Area Forecast Discussion National Weather Service Huntsville AL 1228 PM CDT Thu Aug 29 2024 ...New AVIATION... .NEAR TERM... (Rest of Today) Issued at 1042 AM CDT Thu Aug 29 2024 A strong 500-mb high will remain centered to the immediate east- northeast of the local forecast area today, providing another afternoon of hot temperatures around the region, as air temperatures are predicted to range from the lower 90s in elevated terrain to between 95-100F in most of the valley. Although sufficient boundary layer mixing may occur across the northeastern corner of the CWFA to drop dewpoints into the l-m 60s this afternoon, values will remain in the m60s-l70s elsewhere, translating to heat indices in the 100-105F range (and 105-107F range in the immediate vicinity of the TN River as well as in the Huntsville/Decatur/Florence metropolitan areas). Thus, a Heat Advisory will go into effect for all but our northeastern AL and southern TN counties at 12PM CDT and run through 9PM CDT. Latest data from the CAMs still suggests that showers and thunderstorms will begin to develop in the warm and increasingly unstable airmass across the TN Valley between 12PM-1PM with storm coverage expected to be greatest (35-45%) across the southwestern half of the forecast area from mid-late afternoon. Although vertical wind profiles are not favorable for organized convection, MLCAPE in the 1500-2000 J/kg range and steep lapse rates in the 0-3KM layer may support gusty outflow winds (up to 30-40 MPH) with the strongest cells. && .SHORT TERM... (Tonight through Sunday) Issued at 159 AM CDT Thu Aug 29 2024 Showers and storms will quickly come to an end shortly after sunset. Due to the more humid airmass being advected in, not as cool tonight with overnight lows bottom out in the lower 70s. One more very hot day is in store to finish out the work week. As the aformentioned shortwave pushes further to the east, better forcing should increase the coverage of afternoon thunderstorms. Once again, there is plenty of instability but not shear. Therefore, not expecting severe storms, but a few storms may produce some gusty winds. A cold front then pushes towards the Tennessee Valley from the NW. Overall a slightly cooler day is forecast on Saturday, but medium chances (40-60%) of showers and thunderstorms are forecast. This should provide some much welcomed rainfall to the area as most locations have barely received measurable rainfall the entire month of August. && .LONG TERM... (Sunday night through Wednesday) Issued at 159 AM CDT Thu Aug 29 2024 Mean troughing extending southward from SE Canada will result in overall lower heights over this region, and cooler temperatures. The trough should flatten more as we go into the mid week. At the surface, a cold front now over the Intermountain West and northern Great Plains will advance to the SE, and reach the Tennessee Valley sometime on Sunday. This front will help bring more clouds, and better chances for much needed rainfall. Going with model and blend averages, the front moving across the area Sunday, along with daytime heating and higher instability should bring scattered showers/thunderstorms mainly in the afternoon and evening. The front should become stationary to our south Sunday night into Monday. Another front north of that will also move southward across the area and become stationary over us or just to our south. Upper level systems moving along the front will make for an unsettled early half of the week, with mostly low/medium rain chances. The blends have went with likely rain chances Wednesday afternoon as a disturbances passes. The GFS/Canadian runs were showing possibility more than the ECMWF. In comparison to the previous week, it will be closer to seasonable warmth with high/low temperatures for the first half of next week. Highs on Sunday, Labor Day, and Tuesday should rise into the upper 80s/near 90, and lows in the mid 60s to around 70. Wednesday should be a bit cooler given higher rain chances - highs in the low/mid 80s and lows in the 60s. Areal rainfall totals into the mid week should range from 1/4 to 1/2 of an inch. && .AVIATION... (18Z TAFS) Issued at 1228 PM CDT Thu Aug 29 2024 Development of SHRA/TSRA is in progress across the TN Valley this aftn, with several cells already noted south of the TN River. Although storm coverage will be greatest btwn 19-23Z, confidence in direct impacts at either HSV or MSL is not high enough to warrant TEMPO groups attm. However, both TAF amendments and AWWs (for lightning and strong wind gusts) may be required on short notice until the convection dissipates btwn 0-3Z. Aside from any impacts from showers or storms, VFR conditions will prevail with development of patchy BR/FG possible btwn 6-13Z given mostly clear skies and lgt/vrbl winds. Sfc winds will veer to SSW after sunrise tomorrow, with diurnal convection expected to develop once again toward the end of the forecast period (30/16-18Z). && .HUN WATCHES/WARNINGS/ADVISORIES...
