(FOX Weather)
According to the FOX Forecast Center, a wide swath of the Gulf Coast and Southeast could pick up 1-3 inches of additional rainfall through the end of the week, with isolated areas approaching 5 inches of precipitation.
Many of the communities that stand to see rainfall are dealing with a precipitation deficit, so the rainfall will be welcome news.
More than 95% of counties in Mississippi and 100% of the parishes that make up Louisiana are coping with unusually dry or drought conditions.
The FOX Forecast Center said it expects the wet pattern to relax over the weekend, which will lead to some drier days.
