DISCUSSION
ISSUED AT 1205 AM CDT SUN OCT 12 2025
MID/UPPER RIDGING CENTERED IN MEXICO WILL DRIFT NORTHWARD AND OVER
TEXAS HEADING INTO THE EARLY-MIDWEEK TIMEFRAME. DESPITE A MORE
PREVALENT SE LLVL FLOW DEVELOPING, DEWPOINTS WILL ONLY SLIGHTLY
CLIMB...BUT STILL ANTICIPATE LOW DAYTIME RHS FOR MOST OF THE AREA
CONSIDERING THE ABOVE NORMAL HIGH TEMPERATURES.
HEADING INTO LATE TUE AND WED, ANOTHER SURFACE HIGH PRESSURE AREA
DIPPING SOUTHWARD DOWN INTO THE MS VALLEY WILL BACKDOOR ANOTHER
SURGE OF DRIER AIR INTO THE REGION.
PACIFIC SHORTWAVE WILL DIG SOUTHWARD AND CARVE OUT LARGER WEST
COAST TROF EARLY IN THE WEEK. AS IT KICKS OUT AND TRACKS ACROSS
THE ROCKIES INTO THE PLAINS IN THE SECOND HALF OF THE WEEK, IT
LOOKS LIKE IT'LL SUPPRESS THE ONGOING RIDGE AS IT TRANSITIONS
EASTWARD. SHOULD THERE BE ENOUGH OF A LLVL MOISTURE RETURN, UPPER
LEVEL CONDITIONS SHOULDN'T BE AS HOSTILE FOR SOME ISOLATED PRECIP
DEVELOPMENT. NOTHING THAT'D PUT MUCH OF A DENT IN THE DROUGHT
CONDITIONS, BUT IT'D BE SOMETHING AT LEAST. 47
