Area Forecast Discussion National Weather Service Huntsville AL 636 PM CDT Fri Jul 14 2017 .UPDATE... For 00Z TAFS. && .NEAR TERM...(Tonight) Issued at 218 PM CDT Fri Jul 14 2017 Thunderstorm coverage continues to increase this afternoon with the bulk of the activity just north of the CWA. We'll be keeping a close eye on any outflow development from the cells to north as that could easily initiate additional convection over parts of the CWA. Mesoanalysis is indicating sfc based CAPE ~2000 J/kg and LI around minus 5, so expecting a quick development of storms this afternoon especially around the boundary interactions. 12z sounding data from BMX and OHX were showing favorable conditions for increased thunderstorm activity today but lapse rates and a relatively warm atmosphere through the layer are not incredibly conducive for widespread strong to severe storms. However, cannot rule out an isolated storm or two, especially in the northern zones, becoming severe. Temps across the area are generally in the low 90s with heat index values near 100. .SHORT TERM...(Saturday through Sunday) Issued at 218 PM CDT Fri Jul 14 2017 We will start to see a bit of a transition in the pattern beginning on Saturday as a weak cold front shifts through, or washes out over, the region. Deep layer, and strong ridging, through the upper levels will moderate as a short wave trough swings through the SE US. As that short wave encroaches on the TN Valley, expect another round of scattered to numerous thunderstorms on Saturday afternoon. Much like the last few days, cannot rule out an isolated storm becoming severe, but overall widespread strong to severe weather is not expected. Thunderstorm threat will start to diminish around sunset and through the late night as the mid/upper level wave shifts east and flow becomes more zonal. Winds will veer and gain a northerly component early Sunday helping to filter in some drier and slightly cooler air. As such, rain chances were knocked down to the 20-30 percent range on Sunday. Temps are expected to moderate by Saturday, and fall back into the mid/upper 80s for Saturday and Sunday afternoons with lows dipping into the upper 60s on Sunday and Monday mornings. .LONG TERM...(Sunday night through Thursday) Issued at 218 PM CDT Fri Jul 14 2017 The front is still forecast to stall south of the area Sunday night. During this time, model guidance shows additional waves of energy moving southeast into the area around the surface low over the Great Lakes region. Although the atmosphere will not be as moist, the forcing/better shear associated with this energy should be able to produce some isolated to scattered showers and thunderstorms. Cloud cover and precipitation should keep highs from climbing much above the upper 80s to lower 90s, but it will remain humid with heat index values around 100 degrees. Even drier air aloft pushes into the area Tuesday night into Wednesday. This is mainly courtesy of a strong and very warm area of high pressure building east into the area from the southwestern U.S. This area of high pressure should further reduce any shower and thunderstorm potential to isolated at best the remainder of the week. Unfortunately, it will also bring warmer temperatures via 925 mb flow into the area. 925 mb temperatures climb to between 25 and 30 degrees in many models Wednesday of next week. This continues to build through the end of the week over the area. Raised high temperatures a bit into the mid 90s across much of the area during this timeframe. It could even be hotter than this if some model guidance is correct. Dewpoints should remain in the 60s to near 70 degrees at the very least. So heat index values may flirt again with advisory criteria, but could remain below with values between 100 and 105 degrees fairly common. This timeframe will need to be monitored for a minor heat wave if forecasted air temperatures continue to go higher. && .AVIATION...(For the 00Z TAFS through 00Z Saturday evening) Issued at 636 PM CDT Fri Jul 14 2017 TSRA are moving across portions of the area bringing drops in VIS to MVFR directly underneath the storms. These TSRA should move off to the southeast or dissipate after 15/02Z. Then, scattered to broken cloud cover with VFR conditions should prevail prior to a weak front arriving late tonight into early tomorrow morning. SHRA activity may occur with the approach of the front in the early morning hours, but due to the slow movement of the front have instead left VCTS in the TAFs after 16Z-17Z. This front should become the focus for TSRA possibly impacting the TAF sites during the day on Saturday. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
