BATON ROUGE, La. (WAFB) - The gradual trend toward drier weather will start to get underway today. Isolated showers this morning will give way to scattered showers and thunderstorms this afternoon. Rain chances are expected to run about 50%, with highs in the upper 80s to near 90°.

Rain chances will continue to see a slow, but steady decline in the days ahead, running about 40% for Thursday and Friday and dropping to 20% to 30% by the weekend. High pressure currently centered over the western Atlantic will build westward across the Gulf, finally putting a bit of a lid on the atmosphere. Of course, the tradeoff this time of year is an increase in heat, with highs expected to reach the low to mid 90s over the weekend.
