PRESSURE BUILDING IN EARLY NEXT WEEK.
NEAR TERM /THROUGH THURSDAY NIGHT/
HIGH PRESSURE WILL BE BUILDING IN FROM THE WEST THROUGH THE NEAR

LOW LEVEL CLOUD COVER THAT WILL KEEP TEMPERATURES A FEW DEGREES
WARMER TONIGHT AND LIMIT THE FROST POTENTIAL. FOR THURSDAY NIGHT,
HIGH PRESSURE WILL BE SITUATED OVER TOP OF THE AREA AND ALLOW FOR
EFFICIENT RADIATION COOLING WITH CLEAR SKIES AND CALM WINDS. THIS

MORE EFFICIENT RADIATIONAL COOLING, FREEZING TEMPERATURES WILL BE
POSSIBLE, THOUGH THAT SHOULD BE FAIRLY LOCALIZED. HIGH TEMPERATURES
