Area Forecast Discussion...UPDATED National Weather Service Huntsville AL 637 PM CDT Wed Aug 15 2018 .UPDATE... For 00Z TAFS. && .NEAR TERM...(Tonight) Issued at 304 PM CDT Wed Aug 15 2018 Skies have become mostly clear across the TN Valley this afternoon, allowing ample heating to send temperatures into the upper 80s to low to mid 90s. Based on latest trends, temps may rise by another degree or two before we lose daytime heating with the setting sun. An upper level shortwave will shift east of the Mississippi River tonight, though little impact to the sensible weather pattern is expected over the TN Valley. Thus, a quiet night is expected across the area, with only a slight increase in cloud cover. These clouds, along with a light southwesterly flow continuing to advect moisture into the region, will keep temperatures from falling too much, with lows expected to be in the upper 60s to lower 70s by daybreak on Thursday. .SHORT TERM...(Thursday through Friday night) Issued at 304 PM CDT Wed Aug 15 2018 The shortwave currently over the Mississippi Valley will swing into the Ohio Valley on Thursday, though models weaken this feature as it moves eastward. This weakening will limit the flow aloft, with near zonal flow expected as far south as the TN Valley. Given this cut off of any deep layer moisture, and the lack of strong lift aloft, only isolated to scattered thunderstorms are expected on Thursday. Daytime highs will be on the warm side, once again, with highs topping out in the upper 80s to lower 90s. Another trough will dig southward and into the Mississippi Valley Thursday night, swinging eastward through the overnight hours. Southwest flow will increase aloft, helping to advect an abundance of moisture into the region. Given the rapid increase in moisture, along with enhanced lift associated with an impulse rotating around the trough, numerous showers and thunderstorms are anticipated through the day. Isolated stronger storms are possible, given ample instability and at least some weak 0-6 km shear in place, though the threat is low. The axis of the trough will shift east of the TN Valley Friday night, with lingering showers and thunderstorms possible overnight. The increase in rain chances, along with cloud cover, will keep temperatures in the mid to upper 80s. Overnight lows will be fairly mild, with temps in the lower 70s. .LONG TERM...(Saturday through Tuesday) Issued at 304 PM CDT Wed Aug 15 2018 A wet start to the weekend looks to be in store across the TN Valley, as the axis of the upper trough remains just east of the area and northwest flow persists aloft. Several impulses are forecast to move through the region, and with ample moisture in place, scattered to numerous thunderstorms are expected Saturday and Saturday night. Zonal flow aloft returns towards the latter half to the weekend, though models continue to move several impulses through the region. Thus, scattered thunderstorms will be possible through Sunday night. Temperatures over the weekend will be a few degrees below seasonal norms, with highs in the 80s both Saturday and Sunday. Another trough is expected to dig into the Central Plains at the start of the next work week and push eastward. Forecast models are fairly consistent on bringing this trough, along with the associated surface cold front, through the region Monday night and Tuesday. It's still early to pinpoint exact timing, but this may bring a relief to the heat and humidity across the region. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 637 PM CDT Wed Aug 15 2018 VFR conditions will prevail at each terminal through the period. An isolated storm could impact KHSV, briefly, between 00-01z and have included a TEMPO for this possibility. Otherwise, a quiet and mostly clear night is expected. Winds will increase from the SW after sunrise, with an uptick in cloud cover late in the period ahead of an approaching frontal system. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
