A warm front draped over the forecast area will serve as a focal point for the development of showers and embedded thunderstorms through Tuesday and continuing into Wednesday. With plenty of moisture in the atmosphere and an unsettled
weather pattern in place, showers are expected to develop along the front beginning early on Tuesday. Forecast models show the coverage of the showers and rain becoming more wingspread by later Tuesday, with most of the area experiencing a period of steady rain Tuesday afternoon. A weak area of low pressure developing along the warm front, in association with the remnants of Hurricane Isaac, won’t help the situation much…as the forcing from that weak low pressure should touch off the development of more showers. The most steady rain is expected Tuesday afternoon and evening, with the showers then becoming more spotty once again early Wednesday.
By later Wednesday, forecast models show a weak cold frontal zone or wind shift near the area with the potential for more showers and storms in the afternoon. Later this week, the showers are expected to become less numerous but will remain a chance in the forecast each day.
