NEAR TERM /Now Through Tuesday/...An upper level shortwave lifts quickly northeast from the Tennessee Valley towards the Northeast Atlantic coast tonight, with a longwave trough on its heels deepening over the central CONUS. The latter feature will amplify through the day Monday over the Mississippi Valley and ARKLATEX (Arkansas/Louisiana/Texas) regions. At the surface, high pressure is shifting eastward and a cold front is moving over the Mississippi Valley. This front is expected to push through the lower Mississippi River Valley during the day Monday, approaching southeast Mississippi and southwest Alabama by early Monday evening.
Ahead of the approaching front, isolated to scattered showers and storms develop across the area Monday afternoon in an environment characterized by moderate instability (~1500 J/kg MLCAPE) but little deep-layer shear (around 20 knots). While this environment may not support much of a severe thunderstorm threat, vertical wind profiles improve within the frontal zone, which in combination with the available instability could result in a few strong storms right along the front itself as it pushes through late Monday. These would be capable of producing damaging wind gusts and perhaps some small hail. The Storm Prediction Center has highlighted much of the area in a Marginal Risk to reflect this potential. Once the front passes, any strong thunderstorm threat quickly diminishes as gusty northwest winds usher in a much drier and cooler airmass.
Highs on Monday will be warm, reaching the mid to upper 80s areawide. Monday night is a transition period as temperatures range from 50s behind the front to 60s ahead of it. Tuesday will feel more Fall-like as highs remain in the upper 60s to low 70s and dewpoints fall into the 50s. Expect some really pleasant days ahead in the short and extended term! /49
