Shreveport, LA – A stretch of widespread rainfall is expected across the Ark-La-Tex beginning Wednesday and continuing through Thursday night, with forecasters warning of an increasing risk for localized flooding as heavier rain bands develop. Rainfall totals through the end of the week could reach 1–2 inches across much of the region, with locally higher amounts possible.
According to the National Weather Service (NWS) in Shreveport, a Level 1 of 4 flooding risk is in place for Wednesday and Wednesday night, indicating a low-end but notable chance of heavy rain. Probabilities increase sharply on Thursday, when a Level 2 of 4 flooding risk covers a large portion of northwest Louisiana, southwest Arkansas, and east Texas.
Forecasters say the greatest chance for heavy rainfall will occur later in the day Wednesday through the overnight hours, with storms becoming more widespread and productive on Thursday. This uptick in moisture and storm coverage raises the potential for minor flooding, especially in low-lying or poorly drained areas.
The risk zone includes communities such as Shreveport, Bossier City, Texarkana, Natchitoches, and Longview, with surrounding rural areas also under elevated threat as the system strengthens. Roads could experience ponding, and some streams or small creeks may briefly rise if thunderstorms train over the same locations.
NWS officials emphasize that while Wednesday’s risk is marginal, Thursday’s setup supports the potential for more impactful rainfall. Residents traveling across major corridors such as I-20, Highway 71, and Highway 59 should stay alert for slower travel and reduced visibility in heavier downpours.
The system is expected to move out of the region late Thursday night into Friday, but lingering showers may continue before conditions gradually improve.
