Weather Summary for Maine and New Hampshire
National Weather Service Gray ME
806 PM EDT Mon Sep 28 2026

1. Weakening Nor`easter will bring additional beneficial rain
through tonight with coastal impacts gradually diminishing before
the system pulls away from the region on Tuesday.

2. Temperatures move well above seasonal norms by the middle of
the week with dry conditions before a cold front brings a
chance of showers to end the week.

KEY MESSAGE 1 DESCRIPTION...

Vertically stacked and decaying Nor`easter to spin southeast of
New England....but has finally started to move to the northeast
which will lead it into the Gulf of Maine through Tuesday.
Thus...we expect one more night of rainfall and elevated
temperatures before the drying trend begins on Tuesday.

Some details follow...

Rain: Bands of showers/rain will continue to pivot through the
region tonight as the low pressure system makes it/s closest
approach.  HREF PMM graphics suggest some locations along the coast
may see another 0.5-0.75" of rain overnight with amounts
trailing off as you head inland. Rates will generally be light
to moderate and therefore no flood impacts are expected...but
instead a beneficial rain across the region. Shower activity
diminishes after midnight and especially by Tuesday morning.

Wind:  There have been a few gusts 30-35 mph along the NH coast..and
25-30mph along the ME coast today. These will quickly subside this
evening and back more northerly as low pressure moves into the Gulf
of Maine.  No significant wind impacts are expected.

Coastal Impacts: Surge values of continue around 1`but will
subside tonight. With the next astronomical high tide lower than
the one that just passed...we should be done with additional
statements/etc. As for the high surf advisory...6-10 footers
continue along the coast and will also gradually subside
tonight. Have continued the high surf advisory into the evening
to account for the continued wave action...well evident on
coastal webcams this afternoon.

KEY MESSAGE 2 DESCRIPTION...

A ridge of high pressure builds towards the region on Tuesday
and then crests Wednesday before moving offshore by Thursday.
The result will be a drier period of weather with temperatures
warming each day. By Thursday...T8s push to around 13C which
should allow high temperatures to move well into the 70s with a
few spots likely touching 80. This is roughly 10 degrees above
seasonal norms for the beginning of October. A strengthening
polar jet across the US/Canadian border will drive a cold front
towards the region by Friday. At this range...there is only
modest ensemble support for measurable rainfall with the
frontal passage...with no widespread significant rainfall seen
at this time. Therefore, no additional drought relief is
expected across the region after tonight/s rainfall. High
pressure should usher in a cooler/drier airmass for the weekend.
