..SYNOPSIS
A POTENT SHORTWAVE TROUGH OVER THE SOUTHWEST IS FORECAST TO RAPIDLY
MOVE EASTWARD BEFORE MERGING WITH A BROADER UPPER TROUGH OVER THE
CENTRAL US. A FRONT, TRAILING FROM THE FIRST TROUGH/LOW WILL LINGER
OVER THE OZARKS AND RED RIVER VALLEY. A WEAK LEE LOW WILL DEVELOP
AND MOVE EAST AS COLD FRONT MOVE SOUTH. GUSTY WEST/NORTHWEST WINDS
AND DRY CONDITIONS MAY PROMOTE ELEVATED FIRE-WEATHER POTENTIAL.
..SOUTHWEST TX AND RIO GRANDE VALLEY
AS THE UPPER TROUGH APPROACHES FROM THE WEST, LARGE-SCALE ASCENT
WILL SUPPORT INCREASING MASS RESPONSE OVER PORTIONS OF WEST TX. AS
THE WEAK SECONDARY LOW DEEPENS OVER THE SOUTHERN ROCKIES, STRONG
SOUTHWESTERLY FLOW ALOFT WILL OVERSPREAD THE REMNANT WARM/DRY SECTOR
OVER PARTS OF SOUTHWESTERN TX AND THE RIO GRANDE VALLEY. DOWNSLOPE
WINDS AND DIURNAL HEATING SHOULD RESULT IN LOW RH AROUND 20% THROUGH
THE AFTERNOON. WINDS WILL INITIALLY BE SUSTAINED AROUND 15-20 MPH,
BUT EVENTUALLY THE APPROACH OF THE SECOND COLD FRONT WILL SUPPORT
INCREASING GUSTS TO 20-30 MPH TURNING NORTHWESTERLY. THE INCREASING
WINDS WILL OVERLAP WITH LOW RH LATE IN THE AFTERNOON AND INTO THE
EVENING. SOME DRY AND WINDY CONDITIONS MAY EXTENDED EASTWARD INTO
THE WESTERN HILL COUNTRY AFTER DARK. WITH DRY FUELS IN PLACE OUTSIDE
OF RECENT AND EXPECTED RAINFALL, SEVERAL HOURS OF ELEVATED
FIRE-WEATHER CONDITIONS APPEAR PROBABLE.
