(Today through Thursday night) Issued at 1200 AM CST Tue Feb 17 2026 SFC high pressure has shifted east of the area, with a light return flow regime now in place. Above the SFC, ridging aloft persists, though this will continue to be shunted eastward and flattened out by fast quasi-zonal westerly flow. Warming temperatures and increasing humidity with little to no rain chances are expected over the next couple of days, with overnight early morning stratus and a mix of clouds and sun during the daytime. A shortwave trof passing to our north will drag a weak front to our doorstep THU, which could make it into the Piney Woods and Central LA before stalling out THU night. Shower activity is possible on THU amid sufficient MSTR and lift resulting from the passing shortwave and stalling boundary, but otherwise near record high temperatures around 80 are expected. && .LONG TERM...
