Fire Weather Planning Forecast for Western Maine and New Hampshire

.DISCUSSION...
Winds will remain breezy into this evening and even overnight a
steady southerly wind is expected. Recovery has been fine at
night
but the anticipated breeze will likely limit that a bit tonight.
Sunday will feature shallower mixing and increasing moisture but
minimum relative humidity values will still fall to between 40
and 50 percent most places. It will also remain breezy with
occasional higher gusts Sunday ahead of a slow moving cold front.
Not much in the way of wetting rains are expected. Most of the
area should remain dry Sunday with the better chances for rain
coming Monday.
