032 FXUS64 KHUN 191430 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 930 AM CDT Sun May 19 2024 ...New NEAR TERM... .NEAR TERM... (Rest of Today) Issued at 930 AM CDT Sun May 19 2024 A beautiful day is setting up over the Tennessee Valley after early morning fog has dissipated and clouds are thinning east of I-65. Upper ridging will build in from the west today, leading to warming temperatures as sfc high pressure enforces a drier airmass. Look for light northeasterly winds and mostly clear skies today, with afternoon highs in the low to mid 80s. The only adjustments made during the morning update were to better match current cloud cover. && .SHORT TERM... (Tonight through Wednesday) Issued at 254 AM CDT Sun May 19 2024 Another clear/calm night with moist boundary layer conditions will once again creating an environment favorable for patchy fog. High pressure will build into the area early this week, with mostly sunny/dry conditions pushing highs into the mid to upper 80s both Monday and Tuesday. A mid/upper trough lifting into the Great Lakes on Wednesday will force a weak front SE into the Mid South. We could see some additional cloud cover on Wednesday and even a very low (20%) chance for a shower/thunderstorm in the afternoon in northwest Alabama. However, the main theme with the forecast for Wednesday will be the warmth as highs return to the 85-90 degree range once again. && .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... (12Z TAFS) Issued at 551 AM CDT Sun May 19 2024 Patchy dense fog will gradually dissipate by 13-14z. This fog may briefly impact wither terminal, dropping visibilities to IFR levels. By mid/late morning, clouds will begin to scatter out and a return to VFR conditions is forecast through the remainder of the period. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
