FIRE WEATHER PLANNING FORECAST FOR WESTERN MAINE AND NEW HAMPSHIRE
NATIONAL WEATHER SERVICE GRAY ME
303 PM EDT TUE AUG 12 2025
DISCUSSION
DRY CONDITIONS CONTINUE THIS AFTERNOON WITH LIGHT WINDS. GOOD
RECOVERY IS EXPECTED TONIGHT, BUT WEDNESDAY BEGINS VERY SIMILAR TO
THE PAST FEW DAYS: WARMING QUICKLY UNDER FULL SUN. WEDNESDAY WILL
BE THE LAST DAY OF THE HOT CONDITIONS, BUT ABOVE-NORMAL TEMPS
CONTINUE THURSDAY BEFORE A COLD FRONT COMES THROUGH THE AREA.
WEDNESDAY DOES BRING RAIN SHOWERS TO THE AREA AHEAD OF A COLD
FRONT. ISOLATED TO SCATTERED THUNDERSTORMS ARE ALSO IN THE
FORECAST FOR THE AFTERNOON AND EARLY EVENING. THE BULK OF THE
LIGHTNING ACTIVITY SHOULD TAKE PLACE IN NORTHERN NH AND THE
WESTERN ME MOUNTAINS. STORMS WILL BE SLOW MOVING, WHICH WILL HELP
WITH WETTING RAINS. HOWEVER, THESE MAY BE LOCALIZED AND A
WIDESPREAD WETTING RAIN IS UNLIKELY. PASSING COLD FRONT ON
THURSDAY WILL BRING ANOTHER ROUND OF SHOWERS AND STORMS TO THE
REGION WITH MORE COVERAGE FROM THE FOOTHILLS TO THE COAST.
IT WILL REMAIN WARM BUT NOT AS HOT FRIDAY THROUGH THE WEEKEND.
OTHER THAN ANOTHER COLD FRONT BRINGING THE CHANCE FOR RAIN ON
SUNDAY, HIGH PRESSURE ARRIVES WITH ANOTHER PERIOD OF DRY WEATHER
NEXT WEEK.
