Tornado Warning for Sumter County

Sat, 01/03/2015 - 17:03

LATE UPDATE AT 4:12 PM
The storm has lost its circulation, so the NWS has canceled the tornado warning for Sumter County. The severe thunderstorm warning continues for part of Pickens County.

The NWS in Birmingham has issued a tornado warning for Sumter County for the storm near Cuba. It is moving northeast and should pass near York, just west of Livingston and in the general directions of Boligee and Gainesville. This storm is in a prime location to be tornadic behind the warm front with excellent low level shear and a decent amount of instability.

This storm will move into northern Greene and then into southeastern Pickens or Tuscaloosa Counties after that.

* TORNADO WARNING FOR…
SUMTER COUNTY IN WEST CENTRAL ALABAMA…

Confirmed Tornado in Eastern Mississippi, Will Affect Alabama Soon

Sat, 01/03/2015 - 17:01

Storms over eastern Mississippi have become severe this afternoon.  A couple have even become tornadic with confirmed tornado damage in the Rose Hill area southwest of Meridian.   A significant tornado debris signature was observed on radar and spotters confirmed there was a large and extremely dangerous tornado on the ground.

This storm is passing just west of Meridian at this time. It still has a tornado warning on it. It will pass into northern Sumter County and southern Pickens Counties in West Alabama between 4:30 and 4:45 p.m.

Another tornadic cell is just behind the first one, near Paulding MS. It could affect Sumter County later as well.

A quick check of sever weather parameters in that area shows that CAPE values are above 500 j/kg and there is significant low level shear on the order of 350 m2/s2 for surface – 1 km helicity. This is certainly conducive to the formation of tornadoes.

To the north in Mississippi, severe severe thunderstorm warnings are in effect for North Central Mississippi. A severe storm is poised to move into Starkville in the next 10 minutes. The NWS Jackson is upgraded that warning to a tornado warning now.

A tornado watch is in effect until 8 p.m. for West Central Alabama.

Storms Followed by Cold

Sat, 01/03/2015 - 12:14

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

Stormy weather later today will be followed by a big chill later in the week. Central Alabama is under a flash flood watch as we expect a dual threat with flash flooding a possibility along with a marginal threat for severe weather mainly in the form of damaging straight line wind.

CAPE values go into the range of 700 to 1000 j/kg later today and into the evening hours, so the best threat for severe weather comes from about 4 pm to midnight or so. A closed low over the Texas Panhandle will be jetting out to the northeast today and tonight and going positively tilted, so it will help add to the overall lift across the area. The storms are likely to come as discrete cells this afternoon followed by a squall line with embedded strong storms. Be sure to have a way to get weather warnings.

The upper level closed low ejects as an open wave, but we see a major long wave trough being carved out of the Central and eastern US. This will bring us some rather chilly weather for the early portion of January. Come Wednesday and Thursday, I would not be surprised to find us having trouble getting out of the 30s. And those places that do are likely to only reach the lower 40s so it will be a raw day.

We should stay dry until late into next weekend when the next storm system begins to take shape as moisture returns to the Lower Mississippi River Valley. Highs by next Saturday will reach the lower 50s, colder than we typically see for early January.

The weather pattern stays active into week 2 with another cold looking trough around the 15th with still another short wave around the 18th. So I wouldn’t be putting away the winter coats for awhile.

I’m still in Santa Monica, CA, so the Weather Xtreme Videos will be posted a little later than usual due to the two hour time difference between Central Alabama and my location in California. Look for the next Weather Xtreme video here by 10:00 am or so on Sunday. Enjoy the day, but be safe!

Tornado Watch Likely Coming Soon to the West

Sat, 01/03/2015 - 11:35

The SPC is currently working on issuing a tornado watch for areas to the west of Alabama. This initial watch is not expected to include any portion of Alabama. However, as the storm system shifts east, the watches will be shifted east as well. Stay weather aware heading into the afternoon and evening as strong and severe storms will be possible, with the threat of damaging winds, a few tornadoes, and flash flooding.

AREAS AFFECTED…CNTRL/SRN MS…ERN LA

CONCERNING…SEVERE POTENTIAL…TORNADO WATCH LIKELY

PROBABILITY OF WATCH ISSUANCE…80 PERCENT

SUMMARY…PRE-FRONTAL TSTM DEVELOPMENT IS EXPECTED BY EARLY
AFTERNOON WITHIN AN ENVIRONMENT SUFFICIENT FOR ROTATING UPDRAFTS
WITH PRIMARY RISKS OF A COUPLE TORNADOES AND DAMAGING WINDS.

DISCUSSION…COMPOSITE CONVECTIVE OUTFLOW/COLD FRONT EXTENDED FROM
10 W UOX TO 20 W JAN TO 30 W HEZ TO 30 NW LFT AS OF 16Z. FROM THE
JAN AREA SWD TO THE GULF COAST AHEAD OF THIS BOUNDARY…A
DESTABILIZING AIR MASS CHARACTERIZED BY 65-70 DEG F SURFACE DEW
POINTS WAS PREVALENT. VISIBLE SATELLITE IMAGERY SUGGEST THAT WARM
SECTOR TCU/CBS HAVE INITIATED OFFSHORE S OF ATCHAFALAYA BAY. RECENT
HRRR RUNS AND CONVECTION-ALLOWING WRF GUIDANCE ARE CONSISTENT IN
SIMULATING STRENGTHENING OFFSHORE CONVECTION AS IT SPREADS INLAND
ACROSS PARTS OF THE LOWER MS VALLEY INTO THE AFTERNOON. THE HRRR
APPEARS A BIT MORE AGGRESSIVE IN TIMING/AMPLITUDE OF THIS WARM
CONVEYOR ACTIVITY.

DESPITE MOIST-ADIABATIC LAPSE RATES SAMPLED IN 12Z LCH/JAN
RAOBS…SLIGHT SURFACE HEATING IN THE 72-74 DEG F RANGE ACROSS ERN
LA IS ALREADY ADEQUATE FOR MLCAPE AROUND 750 J/KG. VEERED LOW-LEVEL
WINDS /STRONGER WITH NRN EXTENT/ SUGGEST HODOGRAPHS WILL NOT BE
OVERLY LARGE…BUT CERTAINLY SUFFICIENT FOR ROTATING UPDRAFTS
CAPABLE OF A COUPLE TORNADOES AND DAMAGING WINDS. THE MOST FAVORABLE
ENVIRONMENTAL CORRIDOR FOR TORNADOES SHOULD EVOLVE ACROSS ERN LA
INTO SRN MS BETWEEN ABOUT 19-22Z.

Active Day Ahead

Sat, 01/03/2015 - 01:18

Parts of Central, West and Southwest Alabama are under the standard “slight risk” of severe weather today and tonight, with a lower end “marginal risk” farther north and east…

A dynamic storm system will bring a push of warm, moist air up into Alabama today, and we expect a high close to 70 degrees this afternoon. While a few passing showers are possible during the morning and early afternoon hours, the most active weather comes after 4:00 p.m….

Storms will be capable of producing strong, perhaps damaging winds, some small hail, and maybe even an isolated short lived tornado or two.

Additional rain amounts of 2 inches are expected, and some localized flooding issues are certainly possible. A flash flood watch has been issued for parts of North Alabama…

ARCTIC BLAST: One quick note about next week… new guidance is suggesting much of North Alabama will stay below freezing all day Thursday of the coming week as Arctic air rolls into Alabama. Thankfully, it doesn’t look like it will stay for a long period of time, and we do not expect any wintry precipitation issues. The low early Thursday will be in the teens.

Brian will be along in a bit with a new meteorological discussion… and we will have frequent updates on the situation throughout the day.
