.DISCUSSION...
Warmer temperatures are forecast today as southeasterly winds return
along with more sunshine.

A warm front will then lift northward through the area tonight producing
scattered showers and thunderstorms. Gusty southerly winds will bring
increasing moisture and record or near record high temperatures on
Tuesday. The resultant unstable conditions on Tuesday afternoon will
fuel scattered thunderstorms, with showers and thunderstorms becoming
widespread on Tuesday night as a cold front pushes across the region.
Cooler weather and gusty northwest winds will occur on Wednesday in
the wake of the cold front.
