Rain Develops Later Today

8 hours 20 min ago

RADAR CHECK: Nothing showing up on radar at daybreak; the weather is dry and cool across the great state of Alabama. Vic Bell, the ABC 33/40 Skywatcher at Black Creek, just northeast of Gadsden, reports a chilly 38 degrees just before 6:00. Cullman is at 40… Fort Payne is at 41.

The upper low that has been over Texas the last few days will begin to fill and lift out today, and we expect rain to develop over the northern half of the state at some point this afternoon. Then, periods of rain will continue tonight into tomorrow morning. Seems like the most widespread rain will come from about 6:00 this evening through 12:00 noon tomorrow; rain amounts of 1/2 to 1 inch seem likely for our part of the state. The air will be cool and stable; I doubt if we hear any thunder.

TO THE SOUTH: SPC has dropped the standard “slight” risk of severe weather for far South Alabama today and tonight… they now just define a “marginal” risk for the Gulf Coast.

Drier air returns Thursday as the system pulls away from Alabama, with a partly sunny sky and a high close to 70 degrees.

FRIDAY THROUGH SUNDAY: The weather could not be better, with sunny days, fair nights, and a slow warming trend. We expect low 70s Friday, mid 70s Saturday, and a high Sunday close to 80 degrees. Perfect weather for race weekend at Talladega, spring sports, or just about anything else you enjoy outdoors.

The dry weather will likely continue into early next week; see the Weather Xtreme video for maps, graphics, and more details. We see nothing now in modeling to suggest any severe weather threat for North/Central Alabama for the next ten days.

ONE YEAR AGO TODAY: A total of 18 tornadoes touched down across Central Alabama; EF-2 tornadoes hit Bessemer and Graysville… an EF-1 moved through Kimberly. Over 40 people were injured, thankfully there were no fatalities.

    Rain Returns Tomorrow

    Mon, 04/27/2015 - 15:42

    RADAR CHECK: Rain continues to fall this afternoon over much of the Florida Panhandle… the MCS (mesoscale convective system) that brought winds to 100 mph to parts of Baton Rouge and New Orleans this morning is well south of the coast, over the Gulf of Mexico waters.

    On our end of the state, the sky is mostly cloudy, with temperatures generally in the 60s.

    WET WEATHER AHEAD: Rain should become across North/Central Alabama tomorrow morning in the 5:00 a.m. to 9:00 a.m. time frame, and we will deal with periods of rain tomorrow, tomorrow night, and into Wednesday morning. A surface low will pass south of us, on the Gulf Coast, so there is no risk of severe weather for the northern two-thirds of the state, and there probably won’t be much thunder in the stable air.

    TO THE SOUTH: There is a risk of severe thunderstorms on the Gulf Coast tomorrow… from near Gulfport over to Mobile, Panama City, and Apalachicola.

    The rain will taper off Wednesday morning; rain amounts of around one inch are likely for North and Central Alabama. Could drizzle could linger into Wednesday afternoon as the surface low reorganizes near the North Carolina coast. Temperatures will stay below average with highs in the 60s tomorrow and Wednesday. Some communities north of Birmingham could hold in the cool 50s all day Wednesday.

    Drier air returns Thursday with a partly to mostly sunny sky and a high in the 67-70 degree range.

    FRIDAY AND THE WEEKEND: Doesn’t get any better. Mostly sunny days, fair nights, and a slow warming trend. We reach the low 70s Friday, upper 70s Saturday, and low 80s Sunday. Perfect for the races at Talladega (this is race weekend), spring sports, or doing anything outdoors.

    Dry weather will likely continue into early next week; see the Weather Xtreme video for maps, graphics, and more details.

    Cooler Today; Rain Returns Tomorrow

    Mon, 04/27/2015 - 06:21

    COOL MONDAY MORNING: Temperatures are in the upper 40s and low 50s this morning; Vic Bell up at Black Creek near Gadsden reports 43. We stay dry today, but high clouds will increase, coming from the big MCS (mesoscale convective system) over Southwest Louisiana. The high this afternoon will be in the low 70s; the average high for April 27 (for Birmingham) is 77 degrees.

    TO THE WEST: A tornado watch has been issued for parts much of Louisiana until 1:00p CT…

    That MCS is moving southeast, and will not bother the northern two-thirds of Alabama.

    TOMORROW/WEDNESDAY: A surface low will move along the Gulf Coast, meaning the severe weather risk will be confined to the far southern part of Alabama tomorrow; severe storms are possible on the coast from Mobile over to Gulf Shores, Pensacola, and Panama City, but up this way we will just deal with rain. The high resolution NAM suggests the rain could begin early tomorrow morning, and we will have periods of rain through the day, tomorrow night, and into Wednesday morning. We won’t get out of the 60s both days, and with a cool, stable airmass in place I doubt if we hear any thunder.

    Rain amounts of around 1 inch are likely, and the rain will taper off during the day Wednesday as the surface low moves northeast. The sky becomes partly sunny Thursday as drier air works into the state.

    FRIDAY AND THE WEEKEND: The weather could not be better, with sunny pleasant days, fair cool nights, and low humidity. Expect low 70s Friday, mid 70s Saturday, and a high close to 80 by Sunday afternoon.

    RACE WEEKEND AT TALLADEGA: A big thumbs up for the weather. Dry conditions at the Talladega Superspeedway Thursday; maybe some lingering clouds during the morning, partly sunny by afternoon. Then, sunny weather is the story Friday through Sunday with highs generally in the 70s, perhaps close to 80 Sunday afternoon. Friday morning will be cool with mid 40s likely, the low early Saturday will be close to 50, with lows in the mid 50s Sunday.

    The first half of next week looks relatively dry… see the Weather Xtreme video for maps, graphics, and more details.

    ON THIS DATE IN 2011: A generational tornado outbreak produced 62 tornadoes in Alabama, killing 252 people.

    Tornado Debris Signature South of Fort Worth Tonight

    Sun, 04/26/2015 - 22:02

    Sunday, 9:59 pm

    The Fort Worth radar is showing a clear tornado debris signature in the long lived supercell in southwestern Johnson County west southwest of Rio Vista, heading in the general direction of that town. It will pass near Covington and near Grandview on I-35, just north of the split south of Dallas/Fort Worth.

    The TDS is show as the blue circle in the lower right panel (correlation coefficient) from the Fort Worth dual=pol Doppler radar.

    The Andover Tornado of 1991

    Sun, 04/26/2015 - 16:10

    On this day 24 years ago, an F5 tornado devastated the community of Andover, Kansas, in a violent tornado outbreak over the plains of Kansas, Oklahoma and Nebraska. On April 26, 1991, a total of 55 tornadoes developed, 30 of which were rated an F2 or greater. At one point during the storm, three separate F4 or F5 tornadoes – Andover, Red Rock, and Arkansas City – were simultaneously on the ground. 21 people died as a direct result of the April 26, 1991 severe weather – 17 from one storm alone.

    While the April 26, 1991 storm is most known for the destruction of the Andover community, this same twister also hit parts of Wichita, McConnell Air Force Base and other parts of South Central Kansas. The following devastating tornadoes occurred primarily during the afternoon and evening hours across northern Oklahoma and southern Kansas.

    The Andover tornado initially exhibited multiple vortices, producing F3 damage. As it veered north, it bore down on Haysville, Kansas, just south of Wichita. It passed through the southeastern part of Wichita, passing just a mile south of the South Wichita interchange on the Kansas Turnpike. McConnell Air Force Base was next on the tornado’s agenda. The twister crossed the Base’s runways and missed a billion dollar line of B-1B bombers by less than one thousand feet. The southern part of the Base received F2-F3 damage. The Officer’s Club, Base Hospital and base housing were heavily damaged. But the tornado was growing in size and intensity.

    A subdivision near the Sedgwick County/Butler County line was nearly completely leveled as the tornado grew to its highest intensity. As the tornado turned into an F5 monster, it set its sights on the Golden Spur Mobile Home Park in Andover about 6:45 p.m. Warnings mentioning Andover specifically were issued seven minutes before the tornado arrived; however, the sirens in Andover were not working. A police cruiser drove through the park sounding its sirens as a warning. Many of the residents had heard about the approaching tornado from local television coverage and headed to the park’s storm shelter. Others said they would not take shelter until the funnel was visible. Fortunately, the tornado was slow moving and highly visible, and many made it to shelter in time. Over 200 people were huddled in the shelter when the twister struck, annihilating 233 of the 241 homes. The tornado obliterated the mobile home community, killing thirteen people. Twisted frames were the only remains of many of the mobile homes.

    The tornado thankfully moved into more rural territory northeast of Andover, crossing the Kansas Turnpike. Near El Dorado, the tornado literally bounced a huge oil tank over a half mile. When the tornado finally lifted about five miles north of El Dorado, it had been on the ground for forty five miles. A total of seventeen people in the Andover community lost their lives. Right after the Andover tornado lifted, the same storm produced another tornado that was captured on news video as it passed near on overpass on the Kansas Turnpike, which enforced the false belief that overpasses could provide safe shelter during tornadoes.

    Sunny and Warm Sunday

    Sun, 04/26/2015 - 08:04

    No Weather Xtreme Video this morning since I am providing weather support to the Honda Indy Grand Prix of Alabama at the Barber Motorsports Park.

    Much calmer weather expected for Central Alabama today after a challenging weather situation yesterday. Morning low clouds will give way to sunshine this morning with a mostly sunny afternoon expected. Look for highs to climb into the lower 80s across nearly all of Central Alabama even though a weak cold front will be moving through the Southeast US. Much of the moisture was wrung out of the atmosphere yesterday and there is little convergence with the front to force showers. The front will also usher in slightly drier air later today, so all in all a great Sunday for Central Alabama. Showers are still possible across South Alabama and the northern Gulf Coast.

    Central Alabama will be between systems on Monday with a closed low over the Canadian Maritimes and a closed low over the southern Rockies. This closed low will be slow to come our way with Tuesday the day for the weather to change as clouds increase and rain chances go up late in the day as rain advances across the Southeast US. The closed low will open up late Tuesday and Wednesday so I expect to see a good deal of cloudiness along with periods of rain for Wednesday as a surface low moves along the northern Gulf. With the low so far south, I do not expect to see any severe weather with this rainy period.

    As the upper trough moves by early Thursday, we should see improving weather for the end of the week and into the weekend, great news for the races at Talladega next weekend. After a cool couple of days Tuesday and Wednesday, temperatures should climb back into the 70s for the end of the week and into the weekend as surface high pressure settles into the eastern US and the Southeast US.

    Beach goers will have to contend with chances for showers through the middle of the week, but the weather should turn much better after midweek as that surface low moves east. Temperatures will be in the upper 70s for highs today and Monday, but Tuesday and Wednesday will be slightly cooler thanks to lots of clouds and better rain chances with highs in the lower 70s. Highs return to near 80 for the end of the week and the weekend.

    Looking out into voodoo country, another strong trough will move across the Great Lakes around the 5th of May which is expected to bring a front along with rain chances back into the forecast. After a break in the weather another trough will bring another front to the Southeast around the 11th. So the weather pattern remains fairly active as we head into May.

    Looking forward to ending a rather busy weekend with weather and the events at Barber Motorsports Park. James Spann will have the next edition of the Weather Xtreme Video first thing on Monday. Enjoy your Sunday!

    Severe Cyclone Monica

    Sat, 04/25/2015 - 19:52

    On this date in 2006, Severe Cyclone Monica spared the Darwin area as it curved into land early along the North Coast of Australia, making landfall in a sparsely populated area.

    At the time of landfall, the cyclone had an estimated central pressure of 879 millibars. If this estimate is correct, it would make Monica the strongest tropical cyclone ever in the southern hemisphere.

    Of course, reconnaissance aircraft are only used in the Atlantic, so we will never know for sure. Typhoon Tip (1970) is the strongest typhoon ever observed on earth.

    Is the Severe Weather Over for Central Alabama? Yes!

    Sat, 04/25/2015 - 18:35

    Yes!

    The severe thunderstorm watch for East Central Alabama has been canceled as the last storms have moved into Georgia and no addiitonal storms are expected overnight.

    We had one shot at severe weather this afternoon and evening across Central Alabama and it is done.

    The ingredients that were in place over the area are diminishing now. The speed shear is diminishing as the upper level wind max departs to the north. Instabilities are slowly coming down as clouds cover the area. The convection near the Gulf Coast has effectively cut off additional moisture inflow into the area and drier air is moving in.

    There should not be any more convection initiating tonight. There could be a few light showers as the cold front approaches from the north during the pre-dawn hours, but there won’t be any thunder.

    A passing disturbance and conditionally unstable air caused by cold air aloft tomorrow could trigger a few light afternoon showers as well, but they will be a nuisance at worst, not heavy and not lasting very long at all.

    Coosa County Damage Photos

    Sat, 04/25/2015 - 18:22

    @auburnwde reported destruction of a barn in northern Coosa County caused by strong winds in the severe thunderstorm at 5:18 pm, four miles west of Stewartville on County Road 35. The damage is impressive and could have been caused by a tornado or straight line winds, hard to tell until the Weather Service surveys the damage. There were definitely strong winds, over 65 mph near the surface, shown on doplar radar.

    Heavy Storms in Tuscaloosa County, Not Severe

    Sat, 04/25/2015 - 16:04

    Heavy thunderstorms have developed this afternoon across Tuscaloosa County in West Alabama. They are not severe, but they do have lot sof lightning and heavy rain as well as gusty winds.

    They are moving ENE and will move into Jefferson County shortly. They will reach downtown Birmingham before 4:30.

    Across South Central Alabama, storms were developing across Perry and Bibb County, moving toward Clanton.

    The SPC has moved the slight risk severe weather outlook southward about 50 miles, sort of as expected. It is depicted in the radar graphic as a yellow line extending from Grove Hill to Centreville to Columbiana and Talladega. The dark green line indicates the northward extent of the Marginal Risk and the light green line delineates the northern extent of the threat of storms.

    South of US-82, CAPE values are over 2,000 j/kg giving the storms plenty of octane to work with. There is strong speed shear as well. Mid-level lapse rates are moderately strong as well. But there is almost no low level helicity, so tornadoes are not an issue for now. Overall moisture levels have dropped over North Central Alabama as the special balloon release from BMX indicated at 1 p.m. But low level dewpoints are still quite juicy, running in the upper 60s and lower 70s.

    Storms over South Alabama are stronger, including a couple of severe ones. Two severe thunderstorm watches cover South Alabama, but one has not been issued for South Central Alabama yet. Winds gusted to 59 mph at Fairhope when the storms were over Mobile Bay.

    One Severe Thunderstorm Watch Already, Maybe Another Soon

    Sat, 04/25/2015 - 14:29

    By Bill Murray, 2:25 p.m. Saturday

    An approaching upper level disturbance coming across southeastern Louisiana and southern Mississippi this afternoon. Strong thunderstorms extend now from Southwest Alabama through southern Mississippi into southeastern Louisiana. This system has weakened in the past hour or so but still pose a threat as they move into unstable air.

    But a severe thunderstorm watch has been issued for South Alabama and Northwest Florida downstream of this activity.

    Storms that formed on the northern edge of the area of rain and storms have weakened as well. But the SPC is monitoring conditions across South Central Alabama where instabilities have risen to over 1,500 j/kg south of US-82. Strong wind shear will produce organized thunderstorms, including supercells. Low level helicities are not high, so damaging winds and hail are the main threats, not tornadoes.

    There could be an additional severe thunderstorm watch to the north of the new one over South Alabama.

    Overall, the situation looks better for areas north of I-20, with little to no storm development expected. South of I-20, we will continue to be watching the latest developments all afternoon and evening.
