National Weather Service Hazardous Weather Outlook issued 501 am May 8
Isolated to scattered showers and thunderstorms, some possibly severe, are expected to increase Wednesday afternoon and evening over East Texas, Southwest Arkansas, and Southeast Oklahoma, ahead of a weak cold front and associated upper level disturbance. Storms are expected to diminish late over northwest Louisiana. Hail, damaging wind, and the chance for a tornado or two will all be possible.
Additional showers and thunderstorms should redevelop Thursday afternoon and evening over the region near the slow moving front, with the severe weather threat again possible over these areas. This will diminish Thursday night as the front shifts south of the region.
Impacting Union-Caddo-Bossier-Webster-Claiborne-Lincoln-De Soto-Red River-Bienville-Jackson-Ouachita-Sabine-Natchitoches-Winn-Grant-Caldwell-La Salle Parishes.

WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Sixty-six streamflow gauges record flooding in the USA Wednesday, up from seventy-six Tuesday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, we are watching six active flooding events recorded on the network, all in Louisiana.
Watershed Region 1 continues to record flooding midweek. Bayou Dorcheat is up overnight, running more than a foot over flood stage near Springhill. Bayou Bodcau runs six feet over flood stage near Shreveport. Region 4 Calcasieu River continues to flood near Glenmora, a foot and seven inches over the channel. Sabine River continues to flood from the mid-channel station near Burkeville, six inches above flood stage, four feet above flood stage near Bon Wier, TX and two feet seven inches over the channel near Ruliff, TX.
As many drinking water facilities are supplied from surface water reservoirs, the streamflow situation is pertinent to both drinking water supply and quality. High flows can stir up sediment and cause turbidity in the reservoirs, requiring additional treatments to render the water potable. Low flow volume is linked to warmer temperatures in the reservoir and can be an issue for water quality where HABs are present. WT tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's watersheds. Check the watershed layer on the map to see the direction of flow and streamflows that may be impacting drinking water today.
USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
