NATIONAL WEATHER SERVICE GRAY ME
246 PM EDT MON APR 20 2026
DISCUSSION
CLEAR AND COLD TONIGHT WITH MORE AREAS OF FROST EXPECTED. THERE
WILL NOT BE MUCH OF A WARM UP TUESDAY, BUT IT WILL BE QUITE DRY.
DEWPOINTS WILL MIX INTO THE SINGLE DIGITS AND RESULT IN MINIMUM
RELATIVE HUMIDITY VALUES BETWEEN 20 TO 25 PERCENT OVER A LARGE
PORTION OF THE INTERIOR. THANKFULLY WINDS WILL BE RATHER LIGHT. THE
ONE EXCEPTION WILL BE BEHIND THE SEA BREEZE FRONT, BUT IT WILL
ALSO COME WITH RELATIVE HUMIDITY RISING TO MODERATE LEVELS. AFTER A
CHANCE OF LIGHT PRECIPITATION WEDNESDAY, THURSDAY AND FRIDAY LOOK
TO BE BOTH BREEZIER AND DRIER.
