DISCUSSION
ISSUED AT 1235 AM CDT SAT OCT 17 2026
WINDS ARE STILL ELEVATED BEHIND THE COLD FRONT, PARTICULARLY OVER
THE GULF WATERS AND COAST. AS HIGH PRESSURE BUILDS IN THE WAKE OF
FROPA, THE SURFACE PRESSURE GRADIENT LOOSENS AND THE WINDS WEAKEN
THIS AFTERNOON. THE REST OF THE WEEKEND IS COOL AND DRY, WITH
HIGHS IN THE UPPER 60S-LOW 70S, LOWS IN THE 40S/50S AND LOW RH'S.
THE APPROACHING WORKWEEK IS SIMILARLY TEMPERATE, WITH MODELS
LARGELY IN AGREEMENT. SURFACE HIGH PRESSURE TRANSITIONS FURTHER TO
TO OUR E BRINGING AN EASTERLY FETCH OF WINDS ACROSS OUR AREA FOR
MUCH OF NEXT WEEK. THIS SUBTLE DIFFERENCE FROM OUR TYPICAL SE FLOW
IS ENOUGH TO STIFLE MOISTURE DEVELOPMENT AND RAIN CHANCES AND
HELPING TO KEEP PWATS AROUND AND BELOW 1" FOR MUCH OF THE REGION.
THE MAIN CONCERN FOR RAIN CHANCES, ALBEIT LOW, WILL BE MOSTLY
OFFSHORE MONDAY-WEDNESDAY. WITHOUT REPRIEVE FROM RAIN (AND ONLY
PARTLY CLOUDY MID-UPPER LEVELS), HIGH TEMPERATURES GRADUALLY
CLIMB TO THE 80S BY WEDNESDAY, AND LOWS IN THE MID 50S INLAND AND
UPPER 60S TOWARDS THE COAST.
