Radar Update…8:55 p.m. @WVUA23 #alwx

untitled

We are continuing to observe light showers here in Alabama; however, that’ll change late tonight around midnight when a strong band of storms will enter into northwest Alabama. These storms will track through the state throughout Sunday. The greatest risk for severe weather will be for west and northwest Alabama when the line of storms will be their strongest. As they advance, they will be weakening so east Alabama, past the I-65 line, should be out of the highest threat for severe weather. As of now the opportunity for a very quick spin up tornado can not be ruled out for west and northwest Alabama thanks to very strong winds creating shear vorticity. Current timing brings the storms into Tuscaloosa roughly around 2-4 a.m., 3-5 a.m. for Birmingham areas, and 6 a.m. or later for areas east of Jefferson County.  Once the system moves into east Alabama, the weakening storms will only have the power to produce some stronger winds. Quickly following the storms is a massive pocket of cold air that is causing some winter weather advisories for north Alabama because the air will likely cool the rain enough to cause some freezing rain for the far northern portions of the state. Current trends are hinting that this colder air might be catching up with the line of storms back in west Mississippi. If this should be the case, the opportunity for severe weather for us will dramatically decrease…but we will have to wait and see if that ends up being the case. Should we have any tornado warnings tonight, you can get coverage both on our channel and at wvua23.com, under the weather tab that says “Severe WX Live Stream.”

Strong Storms Arriving Tonight…Saturday Evening Update 7:35p.m.

Sevenday_640.JPG

Good Saturday evening! It was an unusually warm day across central Alabama with highs still climbing around 6 p.m. into the mid 70’s. These warmer temperatures are going to have a major roll in the weather that will play out tonight. All day today we’ve only experienced light showers; however, that’ll change late tonight around midnight when a strong band of storms will enter into northwest Alabama. These storms will track through the state throughout Sunday. The greatest risk for severe weather will be for west and northwest Alabama when the line of storms will be their strongest. As they advance, they will be weakening so east Alabama, past the I-65 line should be out of the highest threat for severe weather. As of now the opportunity for a very quick spin up tornado can not be ruled out for west and northwest Alabama thanks to very strong winds experiencing shear vorticity. Once the system moves into east Alabama, the weakening storms will only have the power to produce some stronger winds. Quickly following the storms is a massive pocket of cold air that is causing some winter weather advisories for north Alabama because the air will likely cool the rain enough to cause some freezing rain for the far northern portions of the state. This isn’t expected to make it down into our DMA, besides maybe a few locally independent areas north of Jasper that may only get some freezing rain for thirty minutes. Even then, ground temperatures will be so warm any ice that falls will melt. Should we have any tornado warnings tonight, you can get coverage both on our channel and at wvua23.com under the weather tab that says “Severe WX Live Stream.”

Sunday will be much cooler as we watch showers and a few lingering storms finishing moving through the state during the day. Highs will be a total reverse from highs today with temperatures only getting into the 40’s. 

Christmas work week will start off with some clouds still sticking with us as temperatures slowly start to warm up. The clouds will be gone by Tuesday. Sunshine Tuesday will help get highs back into the 50’s. Wednesday, just when we thought the rain was gone, a new system that will be developing in southern Alabama will bring rain across that southern half late Wednesday and for the day Thursday. Friday clear weather arrives again. Christmas weekend looks to have showers arriving to try and spoil the Christmas spirit.

Low End Severe Risk Late Tonight… Saturday AM Update – 9am #alwx @wvua23

day1otlk_1300

Good Saturday morning! Temperatures continue to warm with a breezy south wind; in-fact, temperatures could reach the middle 70s this afternoon and remain in the 70s through the overnight hours. As moisture continues to increase, a few showers will remain possible at times today, but severe weather is not expected during the day today.

A deep upper air trough will send a sharp cold front into Alabama late tonight and in the pre-dawn hours Sunday morning. There will be an incredible thermal gradient along the front, with temperatures near 70 before the front arrives at your house, then falling into the upper 30s to low 40s within an hour or two behind the front. By the time you wake up tomorrow morning, the cold air will have already taken over all of west and central Alabama. Sunday will be a cold day, with periods of rain through lunch. Temperatures will remain in the 30s all day on Sunday.

Ahead of the cold front, there is a small risk of a few strong storms and maybe a severe storm or two. The higher chance of a severe storm developing will be to the west of HWY 69 across west and northwest Alabama. This is where the highest combination of wind shear, instability and uplift will occur. Fortunately, the forcing to get storms developing will be lagging just behind the cold front, so I expect elevated storms and heavy rain in the colder air directly behind the cold front. Elevated storms do not produce tornadoes. The low end risk of an isolated tornado would be for a spin-up along the leading edge of the line of storms or if any storms can form ahead of the main line. Again, the risk of tornadoes is very low tonight, but not impossible.

The line of storms will enter northwest Alabama sometime around 10pm to midnight, then progress southeast through sunrise. The risk of anything strong to severe will end by 4am along I-59 and by 6am for areas in a line from Demopolis to Clanton to Anniston. Keep in mind, once the cold air reaches you, the risk of severe weather will be over for you. Severe weather is not expected for areas along or to the east of I-65.

Be weather alert tonight, and if a tornado warning is issued, tune into WVUA/WUOA for non-stop coverage.
