Severe Thunderstorm Warning: Lamar and Marion Counties

Mon, 04/20/2015 - 00:28

Posted 12:31 a.m.

UPDATE AT 12:45 AM
Trees are reported down at Shottsville in Marion County.

ORIGINAL POST
Strong winds from a heat burst or similar phenomenon has caused a 66 mph wind gust at Columbus AFB just across the border in Mississippi from Lamar County. These winds can cause damage.

The storms near Caledonia MS could produce large hail as well. This activity will push to near Vernon in Lamar County.

THE NATIONAL WEATHER SERVICE IN BIRMINGHAM HAS ISSUED A

* SEVERE THUNDERSTORM WARNING FOR…
LAMAR COUNTY IN WEST CENTRAL ALABAMA…
NORTHWESTERN MARION COUNTY IN NORTHWESTERN ALABAMA…

* UNTIL 115 AM CDT

Heat Burst!

Mon, 04/20/2015 - 00:28

Decaying thunderstorms over South Central Mississippi have caused a phenomenon we normally only see across the Plains: a heat burst.

As thunderstorms die, evaporating precipitation falling into dry air making the more dense that its surroundings. It sinks and heats by compression, drying at the same time.

When this air hits the ground, it spreads out causing strong winds. Temperatures rise and dewpoints drop rapidly. This happened at Jackson MS in the past hour.

This could reach over into Sumter County shortly. Interesting.

Storms Are Weaker, But Still Pack a Punch

Mon, 04/20/2015 - 00:04

Monday, 12:05 a.m.

Strong storms continue to march across Mississippi tonight, but they have weakened somewhat over the past hour.

There are no warnings in Mississippi now.

There have been reports of large hail and 40 mph wind gusts in the past hour in the storm that is currently near New Albany.

All of this activity will push into Northwest Alabama from Lamar and Marion Counties into Franklin, Colbert and Lauderdale. The storms should continue to slowly weaken.

The threat of severe weather is diminishing as the storms move into more stable air, but there still could be severe weather overnight. We are waiting to see if the watch will be extended into Alabama. We will continue to monitor closely.

Tornado Watch Issued for Mississippi

Sun, 04/19/2015 - 21:04

Click image to enlarge

Posted 9:04 p.m. Sunday

Intense thunderstorms continue tonight over Arkansas and Louisiana. The strongest ones are over Central Louisiana between I-20 and I-49. A tornado warning is in effect for the area just downstream from Alexandria, for a severe thunderstorm that showed indications of a tornado near the Alexandria International Airport earlier. Half dollar sized hail was reported in Tioga in Rapides Parish.

This storm is turning right now a little so it will pass south of Natchez MS.

To the north, a broken line of supercell thunderstorms, many of which are severe, extends along the Mississippi River from Popular Bluff MO to Clarksdale MS south of Memphis.

This activity is along the pre-frontal trough. Closer to the cold front, other strong storms have formed from the Little Rock area to Fordyce and ElDorado in Arkansas.

A tornado watch is now in effect for much of Mississippi until 3 a.m.

BOTTOM LINE
Will this activity affect Alabama overnight?

The short answer is yes. But there are definite signs that the storms will weaken fairly quickly after getting into Alabama around 1 a.m. Instability levels across western Alabama are almost non-existent. The numbers on the graphic are dewpoint values, and you can see they have dropped to near or below 60F across eastern Mississippi and western Alabama. There is really no mechanism for them to recover before the storms arrive.

There is fairly good consensus among the mesoscale models that the storms will pretty much fall apart as they move across the state. Therefore, the threat for widespread severe weather is very low for Alabama overnight.

But, this is Alabama in April, and our weather watchword is “When it comes to thunderstorms, expect the unexpected.” So we will be monitoring their march across Mississippi towards our front doorstep carefully throughout the night. You should too. Have a source for receiving warnings even while you sleep overnight. And check back periodically for updates.

Alabama Weather Situation Update

Sun, 04/19/2015 - 17:18

Posted 5:18 p.m. Sunday

The storm that prompted the severe thunderstorm warning for St. Clair County no longer looks severe, so the NWS went with the lesser Significant Weather Advisory for northeastern Talladega County.

It is part of a broken arc of thunderstorms associated with a pronounced upper level disturbance that you can see in this radar view. There are severe thunderstorm warnings in Northeast Alabama closer to the comma head of the disturbance.

Looking back to the west, you can see severe thunderstorm watches (light blue) and severe thunderstorm warnings (yellow) associated with the line of intense storms that has developed in the past hour or so ahead of a strong cold front. These storms will affect Alabama later tonight and could produce severe weather including damaging winds and hail. An isolated tornado is not out of the question.

STORM SURVEY REPORT
John DeBlock from the NWS reports that the survey team has found EF1 tornado damage in Russell County.

He reports:
Good Evening! We are still on the road in Russell County surveying storm damage. Thus far, we apcan confirm an EF-1 Tornado that touched down just west of Oswichee along AL-165, and travelled Northeast to the Georgia State Line/Chattahoochee, approximately 3.5 miles long. We are currently back tracking to Pittsview, then to the Barbour County line. Russell County Sheriff’s deputies have confirmed trees down on Perry Wells Road, which we strongly suspect is tornado damage. It does not appear that we can connect the damage all the way from one end of the county to another. We will update as information becomes available.

An additional crew will survey the Cherokee County damage tomorrow.

Strong Storms Moving Through B’ham Metro

Sun, 04/19/2015 - 15:45

A cluster of strong storms is moving through the Birmingham Metro right now, but they are not severe. Areas from Bessemer to Hoover and Lake Purdy and north are

They have heavy rain, gusty winds and lots and lots of lightning. Expect one half inch of rain as they pass.

Storms are intensifying a bit over Northwest Alabama, over parts of Winston, Lawrence, Cullman and Morgan Counties. They are not severe at this time.

This second round of storms is being produced by an upper level disturbance in an active El Nino southern branch of the jet stream.

Another round of storms will impact Alabama late tonight. Storms are expected to develop shortly Texas, Arkansas and Louisiana. These storms will move into Alabama later tonight. A severe thunderstorm watch is already in effect for the aforementioned areas.

Dancing With the Stats

Sun, 04/19/2015 - 14:45

The much advertised heavy rainfall amounts have actually lived up to their billing this week across Central Alabama, although it hasn’t seemed like it. Areas within about 50 miles either side of the I-20 corridor have received two to three inches of rainfall in the past seven days with some four to six inch amounts across Lamar and Fayette Counties.

The Birmingham Airport picked up 3.42 inches through yesterday, with another 0.95 inches after midnight this morning, putting the total at 4.37 inches, with a little more rain to go later today and tonight.

Over the past 365 days, BHM has picked up 51.1 inches through yesterday, which is two inches below normal, so the one inch today has brought us to within an inch of normal over the past year. It looks like another two to three inches of rain will fall through next weekend if the GFS is right. Thanks El Nino!

DROUGHT DENTER: The biggest winners in the rainfall derby this week were the parched areas of South and Southeast Alabama where widespread three to six inch amounts were observed over the past seven days from southern Monroe and Conecuh Counties over to Barbour and Henry Counties. More heavy rains this morning of three to five inches of rain fell across Coffee, Dale and Henry Counties, some of the hardest hit by the current drought in that area.

Storms Firing Over Northwest Alabama

Sun, 04/19/2015 - 13:50

Showers continue to grow across northwestern Alabama and northeastern Mississippi this afternoon ahead of an upper level disturbance.

A strong storm is over northern Pickens and southeastern Lamar Counties moving into Fayette and northwestern Tuscaloosa Counties. It already has lots of lightning and heavy rain.

Other incipient storms are over southern Marion County and over western Jefferson County.

This activity will become strong through the afternoon hours. Severe is possible, but will not be widespread.

Round Two Underway

Sun, 04/19/2015 - 13:22

We are now in the beginning of the second round of a triple header of weather action that is underway across Central Alabama on this mid-April Sunday. The first round brought wind damage to Cherokee County and a possible tornado to East Central Alabama’s Russell County. Five cars of a freight train were brown over on a siding near Abbeville. The second round could bring severe weather this afternoon and the final round will affect the area overnight with damaging winds, hail and even isolated tornadoes.

Let’s set the stage:

MESOSCALE DISCUSSION: A second upper level disturbance was crossing the Mississippi River south of Memphis early this afternoon. Showers and storms were increasing across northern Mississippi and northwestern Alabama ahead of the disturbance. The airmass over Alabama was still slightly unstable and with temperatures expected to warm into the middle to upper 70s with clearing moving in from the west, instabilities will exceed 2,000 j/kg soon , which is moderately unstable.

Here are current instability values, running 1,000-1,5000 j/kg over West Alabama.

Dewpoints are in the middle and upper 60s giving the air a humid feel. There is 40-45 knots of bulk shear in areas generally south of US-78 and US-280.

Fortunately, surface winds are out of the south southwest, limiting the low level helicity, which tornadoes need to spin up.

And mid level lapse rates are poor thanks to sinking air behind our first disturbance, which should help keep the storms in check.

ROUND TWO: Round two of our severe weather event is commencing with those developing showers over Northwest Alabama. Showers will continue to grow in intensity through the afternoon as they feed on the increasing instability from the surface heating and between low level temperature profiles. The storms should be discrete and separated.

The bulk shear will allow them to organize and with drier air aloft that has moved in after this morning’s disturbance, damaging winds and large hail should be the primary threat with the strongest storms. These storms should be out of East Alabama by 8-9 p.m. The SPC has just checked in that the chance of a weather watch this afternoon is small at this time.

ROUND THREE: The final round of our event will come courtesy of a strong disturbance rotating around the base of the powerful upper level trough over Oklahoma this afternoon. It will trigger showers and storms to our west by late this afternoon that will cross Mississippi tonight and enter West Alabama just before midnight. The activity should be weakening as we lose the heating of the day but there are indications that instability levels will remain high enough to allow the storms to hold together into the I-65 Corridor. If they do, we could see more severe weather, including damaging winds, hail and even isolated tornadoes.

We will be closely monitoring weather conditions across Alabama this afternoon and tonight. Stay tuned here at AlabamaWX for the latest and most complete severe weather coverage for Central Alabama.

More Storms Ahead

Sun, 04/19/2015 - 12:52

Here is a projection of what the radar will look like over the next 15 hours, via the high resolution HRRR model…

As Bill notes in the post below, we have two additional windows for severe storms in our state… one from about 1:00 until 7:00 p.m…. and another one from around 12:00 midnight tonight through 6:00 a.m. tomorrow.

New showers are forming now over West Alabama…

These will grow stronger in coming hours as they move east… some storms this afternoon could produce hail and strong, gusty winds, but the tornado threat looks very low (although not zero).

The line of storms arriving ahead of a cold front after midnight tonight will also be capable of producing hail and gusty straight line winds. And once again, the overall tornado threat late tonight is low.

One thing to remember, with the ground saturated, some trees will come down, even with gusts under 50 mph.

NWS survey teams will look at damage in Russell County (around Fort Mitchell) this afternoon; they will review the damage in Cherokee and Calhoun Counties tomorrow (this was damage at Leesburg and Pleasant Valley).

Stay tuned for updates…

Round 1 Ending For Central Alabama. Two Rounds to Go.

Sun, 04/19/2015 - 10:14

Active weather continues across Southeast Alabama this morning as severe thunderstorms associated with an upper level disturbance move into Georgia. A strong upper level jet helped to intensify the storms and low level spin in the atmosphere allowed possible tornadoes to spin up.

Wind damage was reported in Leesburg, especially along AL-68 and Keener Driver, with numerous trees down, including one on a house. Injuries were reported. There are a few tweets that it was a tornado, which is possible, but the radar signatures looked more like straight line winds. Doesn’t rule out that it was a tornado, but the damage from strong straight line winds can be as bad as those of a tornado. NWS survey teams will investigate.

Here is an example of the damage at Leesburg:

Further south, there were strong radar indications of a tornado moving across Russell County earlier. There was actually a tornadic debris signature on Doppler Radar for a time. Structural damage was reported just southeast of Fort Mitchell in Russell County.

That storm is in Georgia near Fort Benning now and is again producing a debris signature. The NWS Atlanta notes the debris is as high as 7,000 feet, indicating a significant tornado.

A tornado watch continues for for much of Georgia, Northwest Florida and East/Southeast Alabama, but the threat is over for areas behind the line of storms.

ROUND TWO

The system responsible for our severe weather is a weakening upper level low over the Central Plains. The low is opening up into a strong trough over Kansas and northern Oklahoma this morning. Disturbance one, which caused the morning round of rain/storms is lifting into eastern Tennessee. The next upstream disturbance is crossing the Mississippi River. It will affect Alabama this afternoon. Will the atmosphere be able to recover from the morning rain and storms?

Skies have cleared over Mississippi with drier air moving in behind the first disturbance. This clearing is moving into western Alabama as well. Temperatures will warm into the upper 70s to near 80F this afternoon. This will allow instabilities to increase to over 2,000 j/kg by early afternoon. Scattered thunderstorms should develop in areas mainly along and south of I-59 by 2-3 p.m. or so. Bulk shear will still be running 30-50 knots along and south of I-59, so storms will be able to organize. There will still be over 100 m2/s2 of low level helicity at that time, so we will be watching for the threat of tornadoes as well.

So, severe weather will probably not be widespread with the afternoon round, but there could be a handful of discrete storms that could produce damaging winds, hail and even a couple of tornadoes, mainly along and south of I-59. But everyone needs to remain weather aware through the afternoon.

ROUND THREE

Another event will come into the state overnight as the main axis of the upper level trough affects Alabama. Storms will fire over Arkansas and northern Louisiana by late afternoon and move across Mississippi during the evening. These storms will be crossing into Alabama before midnight. Now the good news is that they should be weakening. But there should be enough instability ahead of the storms to produce additional severe weather during the late night hours. Decent bulk shear means the storms will be organized and hence strong. Strong low level helicities of 125-200 m2/s2 means that a couple of isolated tornadoes are possible as well.

NEW WORK WEEK
Weather should rapidly improve on Monday as a cold front sweeps through the area. Winds will be brisk, out of the west and northwest tomorrow, and dewpoints will be crashing, making it feel chillier despite increasing sunshine from clearing skies. Highs on Monday afternoon will be in the lower and middle 70s. Monday night lows will be in the 40s and lower 50s. Tuesday and most of Wednesday look to be dry before a passing disturbance brings showers back into the forecast as early as late Wednesday, more likely on Thursday.

WEEKEND SNEAK PEEK
Next weekend looks like it will be wet, with heavy rain returning as early as Friday night. Saturday looks very wet.

Stormy Sunday into Monday

Sun, 04/19/2015 - 07:00

To make the blog more user friendly for those using phones and tablets, we are now embedding the Weather Xtreme video at the top of individual posts. You can also subscribe to the Weather Xtreme video on iTunes by clicking here.

***Note: while in production of the morning video a tornado watch was issued for Southeast Alabama and the Florida Panhandle. ***

A large cluster of storms was moving across Central Alabama early this morning. This cluster is adding additional complexity to the forecast today as it helps to stabilize the atmosphere across the state. Stronger storms were noted across extreme South Alabama. Once these storms move east, we should have a lull in the action until the upper level storm system to our northwest brings a final round of potentially severe storms to the area.

Lots of questions this morning on exactly how both the storms along the Gulf Coast as well as the large rain cluster moving through Central Alabama will affect the weather later today. SPC still has an enhanced area outlooked just to our west and all of Alabama remained in a standard slight risk area. It’s worth noting that the GFS MOS numbers for probability are also down for the day and only peak around 40 percent for early Monday morning. In other words, the models are struggling, too.

Since the early morning convection will be gone by mid to late morning, I expect the atmosphere will have enough time to recover as the GFS paints a broad area of CAPE values over 1,500 j/kg for the afternoon hours. Plus we have the mesoscale convective system that should be moving through the area. While the tornado threat is not zero, the helicity and bulk shear numbers don’t seem to be that impressive. The final round of severe potential will come as the cold front approaches late tonight and into early Monday morning, but by then the atmosphere will be worked over a good deal and with the best dynamics lifting well to our north, the storms will probably be weakening though still the potential for damaging wind and some large hail.

The upper air pattern evolves into a broad trough over the eastern half of the country on Tuesday and Wednesday as surface high pressure settles into the region and provides a couple of very nice Spring days. But the good weather does not last long as another front approaches on Thursday and an upper level trough heads our way Friday and Saturday keeping the weather unsettled for Alabama and the Southeast US.

Wet this morning at the beach, but beach goers should see a lull for the late morning and early afternoon before additional storms occur. Highs will be in the upper 70s. Looks like some nice beach weather for midweek.
