Area Forecast Discussion National Weather Service Huntsville AL 227 PM CDT Tue May 16 2023 ...New NEAR TERM, SHORT TERM, LONG TERM... .NEAR TERM... (Tonight) Issued at 227 PM CDT Tue May 16 2023 An agitated Cu field has developed across the Tennessee Valley this afternoon, with a few showers and storms already developing as of 18z. Expect coverage to increase steadily to around 50-60% this afternoon as we hit our convective temps in the mid to upper 80s. With SBCAPE values between 2000-3000 J/kg, these storms will have the potential to quickly go strong to marginally severe during the afternoon/evening period. Once again, shear values will minimal so don't expect much organization with this activity and thus will be very pulse-like in nature. Thus, we'll need to watch for the potential for some wet microburst over the next 3-6 hours. Convection will wane gradually with the loss of heating -- though some showers will linger along residual outflow boundaries overnight. Low cloud cover will settle in overnight into early Wednesday morning, keeping temperatures in the low to mid 60s. && .SHORT TERM... (Wednesday through Friday) Issued at 227 PM CDT Tue May 16 2023 A surface cold front will push through the area late tonight into Wednesday, bringing with it a slightly cooler and drier air mass. As a result, any convection on Wednesday will be focused mainly across central Alabama -- though some low chances for thunder will be possible for areas south of the Tennessee River. Another shortwave trough will ripple across the region on Thursday, providing some additional lift and helping to generate another round of showers and storms (50-60%), especially during the afternoon/evening hours. Behind this shortwave, flow becomes more zonal and subsequently expect a mainly dry and partly sunny day on Friday -- with slightly cooler temperatures with highs peaking in the upper 70s to around 80 degrees. && .LONG TERM... (Friday night through Tuesday) Issued at 227 PM CDT Tue May 16 2023 A deepening upper-low will swing from the northern Plains into the Great Lakes, dragging a cold front through the Mid South/Lower Mississippi Valley and into the Tennessee Valley on Saturday, bringing the potential for another round of showers and thunderstorms. Behind this feature a much drier air mass will push into region for Sunday into early next week as seen by dewpoints which will fall back into the low to mid 50s. The end result should be some absolutely spectacular days with daytime highs in the low to mid 80s with lower RH values and plenty of sunshine to enjoy. && .AVIATION... (18Z TAFS) Issued at 1141 AM CDT Tue May 16 2023 VFR conditions will be the predominant flight category at each terminal this afternoon/evening. Showers and storms will develop by late this afternoon and move into the area this evening, producing localized MVFR conditions due to reduced vis/ceilings. AWWs and amendments will be possible. MVFR ceilings will settle in overnight and persist into the day on Wednesday as rain tapers off. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
