AREAS AFFECTED...EAST TX/NRN LA

CONCERNING...SEVERE THUNDERSTORM WATCH 227...

VALID 210426Z - 210600Z

A MARGINAL SEVERE THREAT WILL LIKELY CONTINUE ACROSS THE ERN PART OF
WW 227 OVER THE NEXT FEW HOURS. THE SEVERE THREAT MAY EXPAND INTO
NRN LA AS THE MCS DRIFTS EWD OVERNIGHT.

SFC ANALYSIS CURRENTLY SHOWS A COLD FRONT MOVING SEWD ACROSS EAST TX
WITH A MOIST AXIS EXTENDING NWD THROUGH THE SABINE RIVER VALLEY INTO
NW LA. SFC DEWPOINTS ALONG THE MOIST AXIS ARE IN THE MID TO UPPER
60S F AND THIS IS HELPING TO MAINTAIN MODERATE INSTABILITY ACROSS
WRN AND CNTRL LA. IN ADDITION...REGIONAL PROFILERS SHOW 40-45 KT OF
0-6 KM SHEAR SUGGESTING THE SHEAR AND INSTABILITY MAY BE ENOUGH FOR
A MARGINAL SEVERE THREAT OVERNIGHT. HAIL AND STRONG WIND GUSTS WOULD
BE LIKELY WITH THE STRONGER CELLS AS THE MCS MOVES INTO NRN AND
CNTRL LA AFTER 06Z.
