Isolated to scattered showers and storms have developed ahead of the main area of rain that is still in Arkansas and Louisiana. These showers are lifting northward through the viewing area, so rainfall this evening and to start the overnight will be isolated to scattered in nature.
The main batch of rain will arrive towards daybreak Saturday and take the entire day to work through. Rain will be heavy at times and we could see a few embedded storms. Rainfall on Saturday could exceed 1 inch in isolated locations with total accumulation by Sunday morning across the area of 1-3 inches. A Flash Flood Watch is up for most of our Mississippi counties.
Rain will exit on Sunday, but a lingering shower is possible south of I-20, especially in the morning hours. We may see a shower or two creep back north on Monday as an area of low pressure (nontropical) develops in the Gulf of Mexico. Depending on its strength and location will determine if we see rain or not, so we will watch that through the weekend. Otherwise, we should clear out for the middle and later portions of next week as high pressure returns and temperatures warm back into the middle 80s.
