AREAS AFFECTED...PORTIONS OF SOUTHWESTERN AND SOUTH-CENTRAL TEXAS
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 010123Z - 010400Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...A LOCALIZED WIND AND LARGE HAIL THREAT WILL BE POSSIBLE
THROUGH LATE THIS EVENING AS SUPERCELLS MOVE OUT OF MEXICO ACROSS
THE RIO GRANDE.
DISCUSSION...STORMS ARE NOTED TO BE OCCASIONALLY INTENSE ON
SATELLITE AND RADAR ACROSS THE EASTERN SIERRA MADRE IN MEXICO THIS
EVENING. HI-RES CAM GUIDANCE SUGGESTS THAT A FEW OF THESE STORMS MAY
PERSIST AND MOVE ACROSS THE RIO GRANDE INTO THE EDWARDS PLATEAU
REGION AND PERHAPS PORTIONS OF SOUTH-CENTRAL TEXAS. THE AIR MASS
ACROSS SOUTHERN TEXAS IS MODERATELY UNSTABLE WITH STRONG DEEP LAYER
SHEAR AHEAD OF THE EJECTING WAVE TO THE WEST ACROSS BAJA CALIFORNIA.
STORMS WOULD LIKELY BE ELEVATED IN NATURE, GIVEN DIURNAL INVERSION
LAYER, WITH THE MAIN HAZARDS BEING LARGE HAIL AND STRONG TO SEVERE
WIND. GIVEN SOME UNCERTAINTY IN THUNDERSTORM MAINTENANCE AND THE
LOCALIZED NATURE OF THIS THREAT, A WATCH REMAINS UNCERTAIN. TRENDS
WILL BE MONITORED THROUGH THE EVENING.
