A new tornado watch has been issued through 6 PM for East Texas and Southeast Texas. Tyler, Lufkin, Conroe, and Houston are a few towns included. Pretty much, all locations east of I-45 and south of I-20 are now in a tornado watch. The strongest storms through the afternoon may produce damaging straight-line winds up to 75 MPH, hail up to the size of tennis-balls, and tornadoes. The threat for strong/long-track tornadoes will increase this afternoon with any discrete supercells in East Texas. The threat for damaging winds will be highest with the squall line now moving just east of Interstate 35.
