The Storm Prediction Center has issued a Severe Thunderstorm WATCH for parts of the eastern Texas Panhandle, northwest Texas, west central Texas, Permian Basin and Big Country regions of west central Texas until midnight.  In the past half hour, isolated storms have developed out ahead of the front across the southeastern and eastern panhandle region and are quickly moving off to the east/northeast. Additional squall line development has also been noted just west of the Midland/Odessa area.  The squall line will further develop both northward and southward over the next several hours and will track quickly east.  The main threats with all the storms across this area his evening will be the chance for damaging winds and hail up to the size of half-dollars.  The tornado threat remains low but not completely ruled out given the dynamics in place.  Have a way to receive weather warnings and be prepared to seek shelter immediately if a warning is issued for your area.
