FIRE WEATHER PLANNING FORECAST FOR WESTERN MAINE AND NEW HAMPSHIRE
NATIONAL WEATHER SERVICE GRAY ME
230 PM EDT WED MAR 18 2026
DISCUSSION
PORTIONS OF THE AREA COULD SEE LIGHT SNOW SHOWERS THURSDAY INTO
THURSDAY NIGHT AS A WEAK COLD FRONT APPROACHES, BUT THESE WILL BE
MAINLY IN THE MOUNTAINS AND POSSIBLY A PORTION OF WESTERN MAINE.
THE SOUTHERLY FLOW AHEAD OF THE FRONT WILL KEEP RH HIGHER THAN
TODAY BUT STILL COULD BE BETWEEN 30-40% OVER NH AND 35-45% OVER
MUCH OF INTERIOR WESTERN ME. A BETTER CHANCE OF RAIN AND SNOW IS
POSSIBLE FRIDAY NIGHT INTO SATURDAY WITH MOSTLY SNOW EXPECTED IN
THE MOUNTAINS WITH A RAIN/SNOW MIX TO THE SOUTH. A WETTING RAIN IS
POSSIBLE IN AREAS WHERE IT STAYS ALL RAIN. TEMPERATURES FOLLOW A
WARMING TREND THE REST OF THE WEEKEND WITH ANOTHER CHANCE OF
PRECIPITATION LATER SUNDAY INTO EARLY MONDAY. TEMPERATURES LOOK TO
COOL DOWN EARLY NEXT WEEK.
