Area Forecast Discussion National Weather Service Huntsville AL 203 PM CST Sun Jan 22 2017 .NEAR TERM...(Tonight) Issued at 203 PM CST Sun Jan 22 2017 Rapidly deepening surface low was located near Clanton, Alabama early this afternoon with sub 990 millibar pressures now noted in central Alabama. Pressures have been dropping steadily all day across north Alabama with a 10 mb drop noted since late last evening. Regional radars show a well defined MCV/QLCS structure on the east/northeast flank of this low from near BHM to Troy. Rather interesting semi-cellular structures were located within this line and will need to be monitored as they progress further north this afternoon/evening. Further to the west, a broad expanse of light/moderate rainfall was located in the comma head region of the system. This entire complex was pinwheeling slowly to the north toward the Tennessee Valley. Main questions for tonight will be precipitation amounts and convective potential. Have included isolated thunderstorms through this evening east of I-65 where some modest MLCAPE is noted and ascent will be maximized. Also enhanced QPF in this area slightly. Overall, additional rainfall of 3/4 of inch to perhaps locally 2 inches may push the Paint Rock to near flood but not expecting widespread issues. Precipitation should begin to wind down after 08-09z as surface low rotates into northeast Georgia. Gradient will tighten significantly however, and after coordination with surrounding WFOs, have issued a wind advisory beginning at 09z. .SHORT TERM...(Monday through Tuesday) Issued at 203 PM CST Sun Jan 22 2017 Be sure to double up on the hair spray on Monday as those winds will be cranking, especially through midday. The high resolution guidance indicates a 10 millibar surface gradient from west/east across the state and 925 millibar winds approaching 50 knots. This will likely equate to gusts of 40 mph, perhaps higher over elevated areas. We may see some light rain/showers linger in the eastern counties through midday and included the PoPs from the blended suite of guidance. Also held the clouds in through early afternoon based on a rather stout low level inversion in place. Surface high builds across the region Monday night with temperatures dropping down into the 30s for the first time in over 10 days. We should see a rather nice warmup on Tuesday with a quick transition to return flow by the afternoon. .LONG TERM...(Wednesday through Sunday) Issued at 203 PM CST Sun Jan 22 2017 At the start of this period (Wednesday and Wednesday night), a passing upper level system mainly south of the region, in a zonal predominate cyclonic flow south of an upper low, will bring rain chances back to the Tennessee Valley for the mid week. Decent amount of upglide in the 290-295K region should result in mostly light and stratiform type rain. This rain will come to an end during Wed night, as a cold front pushes across the forecast area. High temperatures in the low/mid 60s on Wednesday will be the last of a warm trend for a while, as cooler air will filter in for the latter half of the week and upcoming weekend. We are currently in the midst of the 3rd longest stretch in January of above freezing temperatures. This will be coming to an abrupt end, as temperatures for the latter week and beyond will cool close to, or below seasonable norms (around 52/32 by the upcoming weekend). As noted above, highs on Thursday will struggle into the mid/upper 40s. This cooler trend thanks to a continuing northwest flow and lower heights/thickness values --- this is despite partly to mostly sunny skies. Night-time lows Thursday and Friday night will cool to around freezing both nights, and likely below freezing for the weekend. Conditions appears will be dry into early next week. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 1100 AM CST Sun Jan 22 2017 Strong mid latitude system continues to impact the southeast United State and will be the primary factor in our weather through the next 24 to 36 hours. The strengthening surface low will track across northeast Alabama this evening and into the Appalachians on Monday. This will bring substantial wrap around precipitation across both terminal sites this evening through the tonight period along with a gradual veering of the winds to the northwest. Although conditions are somewhat favorable for thunderstorms during the late aftn/early evening period have held off on including in TAFs due to uncertainty. Ceilings will remain quite low and have opted for lower MVFR to IFR for much of the period. Also of note, the intense pressure gradient associated with the lower pressure system will bring strong wind gusts across the terminals overnight into Monday. && .HUN WATCHES/WARNINGS/ADVISORIES...
