TEXARKANA — The National Weather Service forecasts thunderstorms across the region that may be severe today and overnight.
Scattered showers and thunderstorms are expected to develop late this morning into the afternoon across portions of Northeast Texas, Southeast Oklahoma, Southwest Arkansas and North Louisiana, near and north of a warm front that will lift north into Southeast Oklahoma and Southwest Arkansas, according to a hazardous weather outlook issued by the NWS' Shreveport, Louisiana, bureau.
Some of these storms may be severe, with damaging winds, large hail and isolated tornadoes possible. Additional shower and thunderstorm development is possible this evening over portions of East Texas and North Louisiana, ahead of a severe squall line that will develop over Eastern Oklahoma and quickly shift southeast across the region from mid evening through the overnight hours.
The severe weather threat will become more pronounced with this squall line, with damaging winds, large hail, isolated tornadoes and locally heavy rainfall possible. These storms will diminish from northwest to southeast late tonight.
