ALOFT, TROUGHING WILL CONTINUE TO CARRY REMNANT CONVECTION (AND
THE ATTENDANT FRONTAL BOUNDARY) FURTHER OFFSHORE THROUGH THE REST
OF THE DAY ON MONDAY. AFTER IT DOES SO, NORTHWESTERLY FLOW WILL
BRIEFLY ENSUE ACROSS SOUTHEAST TEXAS. RIDGING WILL SHIFT FROM THE
INTERMOUNTAIN WEST ACROSS WEST TEXAS BY WEDNESDAY, DISPLACING
NORTHWEST FLOW AND REINTRODUCING ONSHORE SOUTHERLY WINDS THROUGH
THE REST OF THE WEEK INTO THE WEEKEND. THIS WILL SET THE STAGE FOR
A GRADUAL WARMUP INTO THE LATTER HALF OF THE WEEK. MEDIUM-RANGE
GUIDANCE SUGGESTS THE CENTER OF THE RIDGE AXIS TO BE ACROSS EAST
TEXAS BY THAT TIME WITH A 60-70% CHANCE OF TEMPERATURE MAXIMUMS
REACHING THE 90-DEGREE MARK ACROSS MOST AREAS NORTH OF THE I-10
CORRIDOR.
BY THE END OF THE WORKWEEK, THE 70-DEGREE ISODROSOTHERM MAKES ITS
RETURN FURTHER INLAND ON SOUTHERLY WINDS THAT ALSO GAIN SPEED TO
NEAR 10 MPH. LONG-RANGE GUIDANCE STILL VERY GRADUALLY TRIES TO RE-
INTRODUCE SOME RAIN CHANCES INTO NEXT WEEKEND, HOWEVER, FORECAST
CONFIDENCE REMAINS LOW AT THIS RANGE DUE TO THE VARIATION IN THE
STRENGTH OF THE RIDGE THAT IS YET TO BE RESOLVED. WPC DAY 1-7 QPF
VALUES REMAIN LOWER AS A RESULT, RANGING AT 0.5-1.5 INCHES WITH
THE BULK OF THAT TOTAL COMING IN THE NEXT 24 HOURS.
