The episode as NWS CAR wrote it up.
The weather pattern changed during October allowing more frequent rain events across much of northern and eastern Maine. The most notable impacts of this change occurred across northern and central portions of the region. However...monthly rain totals across Downeast areas were much more variable with some locations only receiving 50 - 90% of normal rainfall for the month. The greater departures below normal generally occurred along the Downeast coast into Hancock county. Severe drought ( D2 ) persisted along the Downeast coast into Hancock county through October. With the growing season ending and most harvesting finished by months end...agricultural impacts were lessened. Rivers and streams in these areas generally remained at below normal levels through the month.
