A Brief Update For Tonight’s Weather

Well there is two bits of good news for tonight’s weather. The first good news is that we will receive even more beneficial rainfall to help bring our deficits down. Even though there is a lull in the rainfall across much of the area at this moment, more rain is expected to move in from the west and southwest.

The second bit of good news is that the SPC has cut the risk areas down a bit from earlier today. Only the southern parts of Barbour, Bullock, and Pike Counties in the southeastern corner of the area remain in the “Slight Risk” for severe storms, with locations in our area south of a line from Auburn to Montgomery to just south of Demopolis in the “Marginal Risk.”

The boundary that is expected to move north as a warm front has not started its move as of yet. With that staying in place, that has kept the convection down near the Gulf Coast, and has allowed temperatures and dew points north of that boundary to be way lower than expected, especially with the amount of precipitation that has fallen already in Central Alabama. There still may be a few thunderstorms with moderate to heavy rainfall, but for nearly the entire Central Alabama area, there will be no severe weather threat through the rest of the evening and the overnight hours.

So bring on the rain, and a few claps of thunder. That will only help me sleep better.

New Tornado Watch to the South and Southeast; First Damage Survey Info

Rain is about to end in the Birmingham metro area, but not before leaving 1.74 inches at my house in Vestavia for a three day total of 3.40 inches. Thank you!

The tornado watch was allowed to expire at 10 a.m. and was not reissued for western Alabama. A new tornado watch was just issued for Barbour, Bullock, Chambers, Elmore, Lee, Lowndes, Macon, Montgomery, Pike, Randolph, Russell and Tallapoosa Counties till 5:00 PM CST.

There are warnings ahead of the line in South Alabama, for parts of Wilcox, Monroe, Butler and Conecuh Counties. There is a slight risk severe weather outlook for areas east of a line from Centre to Clanton to Grove Hill, but that will shoved eastward along with the storms all day. Storms could become severe ahead of the line as the airmass destabilizes with daytime heating over southeastern portions of the area.

National Weather Service survey teams from Birmingham and Huntsville are going over the damage from last nights storms. In the Tennessee Valley, three people died and four children were critically injured in the Rosalie area of Jackson county by an apparent tornado. The same tornado damaged 60 structures in the Ider community in DeKalb County, with possibly 25 destroyed. There were approximately injuries with 10 individuals still hospitalized.

Birmingham Survey Team 1 has confirmed a tornado in Pickens County north of US 82 on CR 35. No determination on length/width, but so far it is at EF1 strength.

Birmingham Survey Team 2 has confirmed tornado damage in Winston County in the Arley area and towards the Helicon FD. So far that looks like EF1 damage.

More Counties Trimmed From The Tornado Watch

| November 30, 2016 @ 5:56 am

As the squall line continues its march across Central Alabama, the National Weather Service in Birmingham have removed Fayette, Pickens, and Winston Counties from the Tornado Watch.

Counties remaining in the watch are Bibb, Blount, Calhoun, Cherokee, Chilton, Cleburne, Etowah, Greene, Hale, Jefferson, Marengo, Perry, Shelby, St. Clair, Sumter, Talladega, Tuscaloosa, and Walker.

Latest Update & Mesoscale Discussion

The part of the squall line that is in the state is currently located stretching from Scottsboro back to the southwest to Pickensville. No convective warnings are in effect for anyone in Central Alabama at this moment. A few counties in the northern part of the state, including Cullman County, are currently under Flash Flood Warnings. The line is slowly pushing to the east, as the cells in the line are moving to the northeast.

The threat for damaging wind gusts and a tornado or two persists across the watch area. Thermodynamic environment ahead of the convective line has changed little over the past hour or so, with the majority of the watch area still characterized by temperatures in the low 70s and dewpoints in the mid 60s. These conditions in tandem with generally moist profiles remain supportive of modest instability and the latest data suggests MLCAPE around 500 j/kg. Kinematic environment has also remained relatively unchanged with only a slight increase in the vertical shear. Subtle backing has occurred at Tuscaloosa and at the Shelby County Airport in Central Alabama as the convection within the pre-frontal confluence moves into the region. There has also been a slight uptick in updraft strength and increased eastward motion with the portion of the line near Jasper. All this to say, the severe threat persists across the region with mesoscale influences playing a large role in modulating storm strength. Damaging wind gusts and a tornado or two remain possible.
