NATIONAL WEATHER SERVICE GRAY ME
500 PM EDT SAT OCT 18 2025
DISCUSSION
DRY WEATHER CONTINUES THROUGH THE WEEKEND. WINDS WILL TURN TO
A MORE SOUTHWESTERLY DIRECTION AND REMAIN FAIRLY LIGHT AS WELL.
INCREASING MOISTURE WILL ENSURE THAT MINIMUM RELATIVE HUMIDITY
STAYS AROUND 40 TO 45 PERCENT. THE NEXT CHANCE AT WETTING RAINS
WILL ARRIVE MONDAY AS A COLD FRONT CROSSES THE REGION. AN ACTIVE
WEATHER PATTERN CONTINUES THROUGH THE UPCOMING WEEK WITH MORE
CHANCES FOR SHOWERS.
