A WEAK AND MOISTURE STARVED COLD FRONT CURRENTLY JUST TO OUR
NORTH WILL SAG SOUTH INTO OUR AREA THIS EVENING AND MAY MAKE IT
SOUTH OF OUR AREA LATER TONIGHT BEFORE WASHING OUT TUESDAY. THIS
FRONT WILL HAVE LITTLE IMPACT OTHER THAN TO TEMPORARILY DELAY THE
NEXT WARM UP. SURFACE HIGH PRESSURE WILL BUILD IN BEHIND THE FRONT
LATER TONIGHT AND TUESDAY AND WILL CONTINUE TO EXTEND INTO OUR
AREA AS IT SHIFTS TO THE EAST WEDNESDAY. THIS WILL KEEP THINGS DRY
AND SEASONABLY COOL INTO WEDNESDAY WITH TEMPERATURES NEAR TO A
BIT BELOW NORMAL. THERE MAY BE LATE NIGHT/EARLY MORNING PATCHY
FROST IN A FEW AREAS OVER THE NEXT FEW NIGHTS, ESPECIALLY NORTH,
WITH THE COLDEST NIGHT LIKELY TO BE TUESDAY NIGHT.
GOOD MIXING WILL LEAD TO LOW RELATIVE HUMIDITY VALUES EACH AFTERNOON
OVER THE NEXT SEVERAL DAYS, WITH MINIMUM RH VALUES LIKELY DIPPING
INTO THE 20S AND 30S EACH AFTERNOON.
HIGH PRESSURE WILL REMAIN IN CONTROL WITH A DRY WEATHER FORECAST FOR
THE REMAINDER OF THE PERIOD THROUGH MONDAY, ALONG WITH A WARMING
TREND. TEMPERATURES WILL BE BACK TO WELL ABOVE NORMAL BY THE WEEKEND
INTO MONDAY, WITH HIGHS NEAR OR ABOVE 80 DEGREES COMMON IN VALLEY
AREAS.
