AFTN.  VERY QUIET PATTERN AND NO OTHER CHANGES ATTM.

PREV DISC;
LIGHT NORTHWEST FLOW EXPECTED TODAY WITH HIGH CENTER STILL JUST
OFF TO THE WEST. THE NORTHWEST FLOW WILL NOT BE ABLE TO COUNTERACT
THE SEA BREEZE... SO EXPECT THE SEA BREEZE TO BEGIN MOVING INLAND
A LITTLE AFTER NOON. HIGHS REACH THE UPPER 70S AND LOW 80S.

THE MOUNTAINS. BUT DO NOT EXPECT SHOWERS.

RADIATIONAL COOLING CONDITIONS AGAIN. TEMPERATURES FALL INTO THE

AGAIN ESPECIALLY IN FAVORED VALLEY AREAS.

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
HIGH PRESSURE WILL HAVE SHIFTED OFFSHORE BY SATURDAY NIGHT
ALLOWING SOUTHERLY FLOW TO RETURN TO NH AND MAINE. WE WILL SEE A

A BIT WARMER THAN THE PREVIOUS NIGHT. SUNDAY LOOKS TO BE THE
COOLEST DAY OF THE WEEK PERHAPS WITH QUITE A BIT OF CLOUDINESS
