PORTLAND, Maine — The heavy rain that is moving into the northeast Monday night into early Tuesday will set a bullseye for northern New Hampshire and western Maine. I am concerned that several inches of rain will fall in a short time, leading to flash flooding.
Currently there is a stationary weather system parked over the mid-Atlantic states. This will be the focus mechanism for heavy rainfall to start the workweek in northern New England.
Look for an area of low pressure to ride over the stationary front Monday into early Tuesday, sparking torrential downpours in western Maine and northern New Hampshire.
Future rainfall estimates have more than 5 inches of rain falling in a short amount of time for parts of the target area mentioned earlier.
That amount of rain on saturated ground will cause significant flooding issues Monday night and Tuesday during the runoff period.
Of note is the rain will end Tuesday as the sun comes out, but the humidity will ramp back up by mid- to late week with another stormy pattern for the upcoming weekend.
