...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
AS WEAK UPPER TROUGHING OVER THE ERN U.S. CONTINUES EWD INTO THE
ATLANTIC THROUGH THE PERIOD...A SECOND SHORT-WAVE TROUGH INITIALLY
OVER THE GREAT BASIN WILL CONTINUE DIGGING SEWD...CROSSING THE FOUR
CORNERS AND REACHING THE CENTRAL/SRN HIGH PLAINS LATE.

INCREASING WITH TIME...AS WEAK CYCLOGENESIS OCCURS ACROSS TX THROUGH
THE END OF THE PERIOD.
...LOWER MS VALLEY AND VICINITY...
LARGE-SCALE SUBSIDENCE ASSOCIATED WITH WEAK SHORT-WAVE RIDGING IN
THE WAKE OF A DEPARTING SERN U.S. SHORT-WAVE TROUGH WILL COMBINE
WITH VERY WEAK LAPSE RATES/MEAGER INSTABILITY TO HINDER THUNDER
POTENTIAL TO A LARGE EXTENT -- ESPECIALLY EARLY IN THE PERIOD.
AS THE WRN SHORT-WAVE TROUGH DIGS SEWD HOWEVER...INCREASING
LOW-LEVEL WARM ADVECTION MAY SUPPORT SLIGHTLY MORE
WIDESPREAD/ELEVATED CONVECTION. HOWEVER...WITH WEAK INSTABILITY AND
ONLY MODEST FLOW ALOFT...SEVERE WEATHER IS NOT EXPECTED.
