428 FXUS64 KHUN 300202 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 902 PM CDT Wed May 29 2024 ...New NEAR TERM... .NEAR TERM... (Tonight) Issued at 902 PM CDT Wed May 29 2024 Tranquil conditions across the Tennessee Valley this evening with high pressure to the north and east still the primary influence of the weather across the region. Just to our south a passing shortwave will generate some cloud cover which will create at least partly cloudy conditions here (especially south of the Tennessee River) overnight. Any light rain showers will remain well to the south. Otherwise, expect a cool and comfortable night with lows dropping into the mid to upper 50s in most locations. && .SHORT TERM... (Thursday through Saturday) Issued at 205 PM CDT Wed May 29 2024 Strong upper level ridging builds over the area through Thursday, as a surface high over the Ohio Valley dominates the weather over the eastern CONUS. Models do show a disturbance moving from Lousiana into SW Mississippi Thursday morning. However, most models have this feature falling apart as it runs into moves further ESE. Do believe locations SW of a line from near Cullman, AL to the Quad Cities area will see some cloud cover impacting them as this occurs, but not precipitation is expected. These clouds will likely to help keep temperatures a tad cooler. It will still be fairly cool even further northeast where clouds will not be as prevalent. Highs on Thursday look to make it into the mid 70s to lower 80s in most locations. Upper level ridging briefly amplifies over the area Thursday night into Friday afternoon. This should keep precipitation associated with a stronger upper level trough axis over Mississippi through then. Lows Thursday night should be similar. Highs on Friday should warm up in response to the building ridging. Highs should climb to between 81 and 86 degrees. Friday night forcing from the eastern edge of the upper level trough axis moves far enough east that isolated to scattered showers and thunderstorms could impact portions of northern Alabama. Shear and instability look too weak for anything but run of the mill thunderstorm activity producing gusty winds, frequent lighting, and heavy downpours. The coverage of showers and thunderstorms should increase in coverage Saturday into Saturday night, as the trough axis swings through the Ohio Valley and a trailing trough axis produces this activity over the area. Again, shear is very weak, but instability may be a bit higher. Still, no severe storms are expected as this time. && .LONG TERM... (Saturday through Wednesday) Issued at 205 PM CDT Wed May 29 2024 This trailing trough axis lingers over the area into early next week, producing daily chances of additional shower and thunderstorm activity. && .AVIATION... (00Z TAFS) Issued at 606 PM CDT Wed May 29 2024 VFR conditions will prevail at each terminal through the period with light winds and a mostly clear sky. && .HUN WATCHES/WARNINGS/ADVISORIES...
