to the south of a broad positively- sheared longwave trough effectively extending from eastern Canada into the southwestern CONUS. A true maritime tropical airmass resides to the south of the second warm front. Regardless of the relatively drier airmass, mid-level ascent associated with southern stream wave has been sufficient to generate widespread light/moderate showers north of the Gulf Coast warm front. there is indication in some of the higher resolution models that the southern warm front may lift northward into at least the southeastern corner of the forecast area, with dewpoints returning into the u50s/l60s. assuming that warm front does lift northward and storms do develop. highs today will be in the m/u 70s -- a few degrees warmer than yesterday assuming that clouds clear during the afternoon. Highs tomorrow will be a few degrees cooler in wake of cold front.
