Area Forecast Discussion National Weather Service Huntsville AL 232 PM CDT Wed Jun 2 2021 .NEAR TERM...(Remainder of today and tonight) Issued at 232 PM CDT Wed Jun 2 2021 There has been little change in forecast reasoning for the remainder of the afternoon, as a broad surface trough/wind shift axis extending from southwestern TN into central MS will continue to focus the development of deep/moist convection as it shifts slowly eastward this afternoon. Residual mid-level cloud cover in the wake of our morning rainfall has cleared sufficiently to allow temperatures to warm into the u70s-l80s across northwest AL (a bit warmer than previously anticipated), and this is supporting pockets of moderate instability with MLCAPE as high as 1500-2000 J/kg per SPC mesoanalysis data. Thus, we still anticipate a threat for strong- marginally severe thunderstorms with deep-layer shear in the 30-40 knot range. Although wind damage will be the primary hazard with storms this afternoon, a very low risk for mesocyclone/brief tornado development does exist given the magnitude of the low-level jet. Models suggest that the primary synoptic surface low (currently lifting northeastward into southern IL) will gradually loose definition as it advances into northwestern OH/southeastern MI by 12Z. The slow-moving surface trough axis will continue to focus a couple of bands of showers and thunderstorms as it progresses eastward across the local area overnight. Although storm intensity will gradually diminish with boundary layer stabilization this evening, sufficient MUCAPE and modest values of deep-layer shear will support a risk of strong storms throughout the night. Otherwise, it will be another warm and muggy night, with lows in the m-u 60s. .SHORT TERM...(Thursday through Friday night) Issued at 232 PM CDT Wed Jun 2 2021 Over the course of the short term period, an upper low is predicted to cutoff in the base of a longwave trough across the central Plains and drift southward across west TX. The more progressive northern portion of the trough will spread eastward through the OH and TN Valleys on Thursday and Thursday night, with lift from this feature maintaining a risk for showers and thunderstorms in the warm/moist airmass to the south of a cold front due to arrive late Thursday afternoon or Thursday evening. Forecast soundings depict a slightly more unstable environment tomorrow due to steepening lapse rates aloft, and this will support another marginal risk for severe thunderstorms given persistent deep layer shear in the 30-40 knot range. However, unlike today, this risk will be more focused across the southeastern portion of the CWFA, where the slow-moving surface trough will likely be located around the time convective temperatures are reached late tomorrow morning. A drier airmass will be advected southward into the region beginning early Friday morning, with little to no chance for precipitation on Friday/Friday night. Temperatures beneath mostly sunny skies will warm efficiently into the m-u 80s on Friday afternoon, but should cool into the lower 60s Saturday morning. .LONG TERM...(Saturday through Tuesday) Issued at 232 PM CDT Wed Jun 2 2021 A mid-level ridge will build northward across the Southeastern CONUS early this weekend, in advance of a cutoff upper low across South TX. This will provide warm and dry conditions on Saturday, with highs in the u80s-l90s. However, it still appears as if deep-layer southerly flow will begin to strengthen across the region late Saturday night in the gradient between a developing mid-level ridge to our east and the cutoff upper low to our west. Low-level southeasterly flow on the western rim of the Mid-Atlantic Bermuda high will also assist in advecting rich moisture northward into the region, with precipitable water values in the 1.7-1.9 inch range and boundary layer dewpoints in the u60s-l70s much of next week. Given the lack of synoptic scale forcing for ascent, we anticipate scattered mainly diurnal convection each afternoon/evening, with highs in the mid 80s and lows in the u60s-l70s. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1228 PM CDT Wed Jun 2 2021 Although a few lgt SHRA are currently in progress across northern AL, present indications are that additional TSRA will develop along a sfc trough/wind shift axis across northern MS and shift eastward later this aftn. We have included TEMPO groups for TSRA and MVFR cig/vsby reductions from 19-23Z/MSL and 21-01Z/HSV, and it should be noted that some of the storms may produce strong wind gusts and frequent CG lighting, warranting the issuance of AWWs. This particular round of convection will likely dissipate early in the evening, with a deck of low/MVFR stratus clouds expected to develop shortly after Midnight. A second round of showers and thunderstorms is possible during the early morning hours on Thursday, with PROB30 groups included for MSL/7-11Z and HSV/9-13Z. Conditions will improve late in the TAF period as low-level flow veers to the WSW. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
