Isolated thunderstorms are possible Wednesday afternoon but flooding concerns in Oklahoma should decrease throughout the week.
The heavy rains and flooding are the result of a strong low pressure system that covers the southern US and will continue to push a cold front eastward throughout Wednesday, according to Weather Underground. Flow around this low pressure system pulls warm and moist air in from the Gulf of Mexico and triggers more heavy rain and severe thunderstorms across the Lower Mississippi River Valley and Southeast. This system will continue causing major flooding problems as it moves eastward throughout the day. Rainfall totals are likely to surpass 3 inches in some areas. There is a a slight chance that severe thunderstorms will develop over the Southeast on Wednesday. If storms turn severe, expect strong winds, large hail, and possibly a few tornadoes. After the cold front passes, slight cooler temperatures are anticipated. Expect highs to range in the 60s and 70s across the Central US.
A flood warning remains in place in Oklahoma for the Poteau River near Panama in LeFlore County. The river was at 35.43 feet Wednesday morning — that's more than 2 feet above moderate flood level. Hydrologists predict that the river will crest at 37.2 feet Wednesday evening before dropping below flood stage on Thursday.
