Area Forecast Discussion National Weather Service Birmingham AL 1136 PM CST Mon Feb 20 2017 .UPDATE... For 06Z Aviation. && .SHORT TERM... Through Tonight. Today we start off with a decaying elongated surface ridge over Eastern Conus along with east to southeast surface winds around its base across Central Alabama. With only thin high clouds today, we had no problem warming up once again today with return flow to well above normal temperatures again. At the same time, in the upper levels, a longwave trough extending from the Dakotas to Texas will continue eastward through tonight. The southern portion of energy from the trough is expected to become a closed low as it moves into Louisiana and Arkansas. In response, the convection we see this afternoon across Arkansas, Louisiana and into East Texas will continue to the east tonight toward Alabama and should arrive here in the wee hours of the night toward sunrise in the west part of the state. With a decrease in intensity expected from this afternoon, activity upon arrival in Central Alabama is expected to be only light to moderate showers. No thunderstorms are anticipated overnight. 08 .LONG TERM... Tuesday through Sunday. Rain will be knocking on our western doorstep at 12Z Tuesday as a closed 500mb trough moves ESE from the Ark-La-Tex. The GFS continues to play catch up to the ECMWF which has been consistently showing stronger lift and higher rainfall amounts. The latest run of the ECMWF is even more aggressive, and POPs have been raised as high as 90 percent for much of the area for Tuesday. High POPs have also been included for Tuesday night with deep southerly flow continuing as the upper low slips to our south across the Gulf of Mexico. Rain chances will diminish as the trough moves away on Wednesday with dry conditions for Thursday and much of Friday. The upper-low lingering near the Bahamas on Thursday into Friday will serve to rob moisture from the next trough moving from the Plains into the Ohio Valley. Unusually warm temperatures are expected with many locations topping the 80 degree mark on Friday. Enough moisture could meet with an approaching cold front for showers to develop Friday night into early Saturday, but potential rainfall amounts appear rather light at this time. A cool morning is expected on Sunday behind the front as high pressure moves into the region. 87/Grantham && .AVIATION... 06Z TAF Discussion. A slow moving closed upper low currently over Texas will bring a large swath of showers into west Alabama by 12z. VFR conds expected thru 12z with only mid to high level clouds and no pcpn. The leading edge of the showers will arrive in west Alabama around 12z and spread to the I-65 corridor by 17z. Cigs will gradually lower from west to east during the day as the rain overspreads the area. MVFR cigs should reach KTCL first with the remainder of the airports lowering to MVFR between 16z and 20z. After 20z, IFR cigs will become more likely, especially from I-65 westward. Sct shwrs will remain in the area through the end of the forecast period due to the presence of the upper low. 58/rose && .FIRE WEATHER... Dry weather is expected through early Tuesday morning. Widespread rain is looking more likely for the daylight hours on Tuesday and on through Wednesday morning. There are no fire weather concerns. && .PRELIMINARY POINT TEMPS/POPS...
