066 FXUS64 KHUN 231116 AAA AFDHUN Area Forecast Discussion...UPDATED National Weather Service Huntsville AL 616 AM CDT MON MAY 23 2016 .UPDATE... For 12Z TAFs. && .DISCUSSION... (Issued 316 AM CDT MON MAY 23 2016) Very quiet and mild night ongoing across the cntrl TN valley this early Mon morning, as an Omega Block pattern remains firmly in control of the wx pattern over the Lower MS Valley/Midwest states. High pressure at the sfc also remains layered over much of the ern CONUS, and little change is xpcted with this trend as the new work week begins based on the latest model suites. With a strong upper ridge pattern just to the w, a gradual warming trend looks to begin over the next couple of days, as the upper ridge translates slowly ewd. Afternoon highs Today mainly in the mid 80s may rebound further into the upper 80s by the Tue/Wed time frame. Overnight lows will also show a slight warming trend, with early morning lows Tomorrow predom in the mid 50s before climbing into the lower 60s early Wed and mid 60s Thu morning. Any rainfall or showers/tstms returning to the forecast doesn`t look very favorable thru mid week, with the upper ridge pattern over the SE states helping to deflect any energy/moisture to the w/n. The latter half of the model guidance does hint at the upper ridge feature weakening/shifting to the e starting Thu, with the sfc high displaced just off the mid/srn Atlantic Coast. This should at least help with some moisture flowing back into the region from the s. The flow pattern out of the wsw should also become a bit more active as weak upper disturbances begin to traverse across parts of the area. All of this should result in some chc for showers/tstms starting Thu and continuing into the weekend period, although for the most part rain chances will be fairly low. Overall temps look to remain seasonably warm heading toward the end of the work week and into the weekend, with most of the region under the influence of the Subtropical ridge. Afternoon highs mainly in the mid/upper 80s look to prevail while overnight lows predom hold in the mid 60s. 09 && .AVIATION... For 12Z TAFs: VFR weather, and generally clear skies should continue across Northern Alabama and portions of Southern Middle Tennessee. Surface high pressure just north of the region should control the general weather situation. Light and variable winds this morning will become NW 5-10 kt during the late morning the afternoon. Winds again should become light and variable after sunset this evening. RSB && .HUN Watches/Warnings/Advisories... AL...NONE.
