461 FXUS64 KHUN 192311 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 611 PM CDT Sun May 19 2024 ...New AVIATION... .NEAR TERM... (Tonight) Issued at 141 PM CDT Sun May 19 2024 A very pleasant spring day is ongoing across the Tennessee Valley as skies have become mostly clear allowing temperatures to rise into the upper 70s/lower 80s. Sfc high pressure will keep dry conditions in place through the remainder of the overnight period, with the main concern tonight being fog development. Clear skies and light winds combined with high near sfc moisture from recent rainfall will lead to a favorable setup for at least patchy dense fog, and this will need to be monitored overnight in case another Dense Fog Advisory is needed. Otherwise, expect lows to fall to the low to mid 60s area wide. && .SHORT TERM... (Monday through Wednesday) Issued at 141 PM CDT Sun May 19 2024 Sfc high pressure will remain anchored to our east as upper ridging builds over the area, resulting in a dry but warming forecast through the short term period. Expect highs in the mid to upper 80s each day, with a few locations potentially hitting the 90 degree mark. Will start the week with light southeasterly flow, increasing on Wednesday as gradient flow tightens between the broad ridge to our south and upper troughing digging into the upper Midwest. Overall, could not really ask for better weather for late May, even if it is a tad bit warm. Remember to practice heat safety and remain hydrated if spending time outdoors! && .LONG TERM... (Wednesday night through Saturday) Issued at 254 AM CDT Sun May 19 2024 The aforementioned cold front will clip the Tennessee Valley Wednesday night into Thursday, bringing low to medium (30-60%) chances for showers and thunderstorms -- before this activity tapers off Thursday night. We may stay in an active pattern to kick off the Memorial Day holiday weekend, thanks to zonal flow aloft allowing a couple of shortwaves to ripple through the area both Friday and Saturday. This will bring some additional chances for showers and thunderstorms both days. Despite the cloud cover, temperatures should still reach the low to perhaps mid 80s each day. && .AVIATION... (00Z TAFS) Issued at 610 PM CDT Sun May 19 2024 With high pressure in place across the region, VFR conds are generally expected thru the TAF period. The only exception may be some -br/MVFR vis early Mon morning. Light/var winds will also become SSE around 5-7kt Mon morning. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
