Sherman, Texas – Damaging wind gusts up to 70 mph and hail as large as 1.75 inches could hit parts of north and northeast Texas before sunset Wednesday, with southeastern Oklahoma also in the threat zone.
According to the National Weather Service Storm Prediction Center, a severe thunderstorm watch may be needed later this afternoon or evening as instability increases across the Red River region. Forecasters place the probability of watch issuance at 40 percent through early tonight.
Warm, humid air with dew points in the mid to upper 60s is fueling isolated storm development from the Dallas-Fort Worth area north toward Sherman and Denison. While storm coverage may remain scattered at first, steep midlevel lapse rates and increasing wind shear could allow individual cells to produce quarter- to ping-pong-ball-size hail and localized damaging wind bursts.
By early evening, a strengthening low-level jet may help storms organize across Grayson County, Cooke County and into Bryan County, Oklahoma. Travel along U.S. 75 and U.S. 82 could become hazardous in heavy downpours with sudden visibility drops.
Residents should secure vehicles under cover, remain weather-aware and prepare for possible warnings. Additional updates and a potential watch issuance could follow before nightfall.
