500 PM EDT Fri Aug 22 2025
.DISCUSSION...
Winds will relax tonight with good RH recovery. High pressure
will
continue dry conditions Saturday with steady onshore winds
allowing to min RH yo be higher than today. A slow moving cold
front will approach from the west Saturday night and Sunday with
increasing south winds ahead of the front. Gusts up to 35 mph
will be possible across much of southern ME, with gusts to 30 mph
for much of NH.
Incoming cold front Sunday has trended slower, thus much of the
region appears to remain dry during the wind window Sunday.
Advancing from the west, best chance for daytime showers will be
over the western mountains. Widespread wetting rainfall is then
expected Sunday night through Monday.
