Severe thunderstorms are not expected on Thursday. ...Synopsis... An amplifying upper wave will continue to translate eastward across the eastern CONUS through the day Thursday before moving off the Atlantic Coast by late evening. At the surface, an attendant cyclone will continue to drift north/northeast into eastern Quebec as it begins to occlude. A trailing cold front will start the forecast period draped from the Northeast into the Southeast states, and is forecast to gradually shift east through the day before moving off the East Coast and stalling across the FL peninsula as broad-scale ascent weakens. Thunderstorms will likely be ongoing along the front at the start of the period across portions of southeastern AL, western GA, and the FL Panhandle. Lingering 40-50 knot mid-level flow may support a few organized thunderstorms during the morning hours - mainly along the I-10 corridor. However, it is unclear how intense this activity will be given linear/clustered storm modes and a marginal thermodynamic environment during the diurnal buoyancy minimum. Regardless, steady weakening is anticipated through the day as convection drifts into an environment with decreasing mid-level lapse rates and diminishing forcing for ascent. Across the northern High Plains, cold mid-level temperatures associated with a clipper low may support pockets of sufficient instability for lightning production. Steep low-level lapse rates and strong flow within the lowest kilometer may support a few stronger gusts, but the overall thermodynamic environment appears too limited for risk probabilities at this time. ..Moore.. 03/10/2026 $$
