VALID 140356Z - 140530Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 252 CONTINUES.
SUMMARY...THE LEADING EDGE OF AN MCS WILL CONTINUE TO ADVANCE
EWD/SEWD ACROSS PARTS OF THE E-CNTRL/SERN TX PANHANDLE. AN ISOLATED

HEMPHILL COUNTY TO ARMSTRONG COUNTY WILL CONTINUE MOVING EWD/SEWD.
THE AIR MASS AHEAD OF THIS ACTIVITY SHOULD REMAIN SUFFICIENTLY
UNSTABLE IN THE SHORT-TERM FOR AN ISOLATED/MARGINAL SVR WIND/HAIL
RISK. HOWEVER...AS RELATED OUTFLOW CONTINUES TO SURGE AHEAD OF
PARENT CONVECTION...AND NOCTURNAL STABILIZATION OF INFLOW OCCURS
AMIDST WEAK LOW-LEVEL FLOW...THE SVR RISK WILL CONTINUE TO DIMINISH.
