THUNDERSTORMS IS THIS AFTERNOON INTO THE FIRST PART OF THIS
EVENING.
MUCH DRIER AND BREEZY CONDITIONS FOLLOW FOR FRIDAY WITH WEST
WINDS BETWEEN 15 AND 20 MPH GUSTING TO 35 MPH.
MINIMUM RELATIVE HUMIDITY VALUES FALL TO AS LOW AS 30 TO
35 PERCENT ACROSS THE INTERIOR. SLIGHTLY HIGHER VALUES ACROSS THE
CAPE AND ISLANDS WITH VALUES BETWEEN 45 AND 55 PERCENT.
OUTLOOK...FRIDAY NIGHT THROUGH MONDAY
NEAR TO SLIGHTLY ABOVE NORMAL TEMPERATURES CONTINUE THROUGH THIS

CHANCE FOR A POPUP SHOWER OR THUNDERSTORM SUNDAY, BUT MANY HOURS
