High based dryline storms forecast today.
TX CAPROCK THIS EVENING...
A DRYLINE WILL BECOME BETTER DEFINED THIS AFTERNOON AS MIXING AND
THE LEE TROUGH CONSOLIDATE THE MOISTURE GRADIENT NEAR THE CAPROCK.
THOUGH THERE IS NO CLEAR LARGE SCALE SUPPORT FOR THUNDERSTORM
DEVELOPMENT...L0W-LEVEL ASCENT ALONG THE DRYLINE MAY SUPPORT THE
DEVELOPMENT OF A HIGH-BASED STORM OR TWO THIS EVENING. VERTICAL
SHEAR IS FORECAST TO BE SUFFICIENT FOR SUPERCELLS IN AN ENVIRONMENT
WITH MLCAPE OF 750-1000 J/KG...AND ISOLATED LARGE HAIL AND/OR STRONG
GUSTS WILL BE POSSIBLE. STILL...SPARSE STORM COVERAGE SUPPORTS ONLY
LOW HAIL/WIND PROBABILITIES.
