AREAS AFFECTED...PARTS OF SOUTHEAST TEXAS
CONCERNING...SEVERE THUNDERSTORM WATCH 246...
VALID 270721Z - 270915Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 246
CONTINUES.
SUMMARY...EMBEDDED STRONG TO SEVERE GUSTS REMAIN POSSIBLE WITH AN
EASTWARD-MOVING MCS. A DOWNSTREAM WATCH ISSUANCE IS NOT EXPECTED.
DISCUSSION...THE LATEST RADAR DATA FROM KHGX INDICATES AN MCS
TRACKING EASTWARD ACROSS SOUTHEAST TX AT AROUND 30-35 KT. GIVEN THE
WELL-ESTABLISHED COLD POOL, AROUND 40 KT 0-6 KM SHEAR (PER VWP
DATA), AND MOIST INFLOW (LOWER 70S DEWPOINTS) FOR THIS SYSTEM,
STRONG TO LOCALLY SEVERE GUSTS (50-60 MPH) WILL REMAIN POSSIBLE AS
IT CONTINUES EASTWARD OVER THE NEXT COUPLE HOURS. HOWEVER, GIVEN THE
ORIENTATION OF THE MIDLEVEL TROUGH AND ACCOMPANYING MIDLEVEL FLOW,
WEAKENING UPPER-LEVEL SUPPORT AND INCREASINGLY LINE-PARALLEL
DEEP-LAYER SHEAR SHOULD TEND TO LIMIT CONVECTIVE INTENSITY WITH
EASTWARD EXTENT -- ESPECIALLY GIVEN THE LACK OF A STRONGER LOW-LEVEL
MASS RESPONSE. THEREFORE, A DOWNSTREAM WATCH IS NOT EXPECTED.
