223 AM EDT Tue Sep 29 2026

1. A nor`easter will continue to weaken as it exits east today
with much of the remaining rainfall ending this morning.
Additional impacts from this system are not expected.

2. Temperatures run well above normal by the middle of the week
with dry conditions before a cold front brings a chance of
showers late Friday.

KEY MESSAGE 1 DESCRIPTION...

Latest surface analysis shows a weakening nor`easter tracking
northeast across the Gulf of Maine. This system will continue
rain chances into the pre-dawn hours with chances diminishing NW
to SE through mid morning. Winds will generally be light and
shift N to NW through today. Waves heights have been on the
downward trend and will generally be less than 5 feet by this
afternoon. Clouds will likely hang tough along the coast into
the afternoon with breaks in the clouds across the interior.
Highs today will range from near 60F across the north to 70F
across southern NH. Dewpoints will be elevated and will stay
that way into tonight that will bring potential for areas of
fog.


KEY MESSAGE 2 DESCRIPTION...

We will see a series of upper level ridges move across the region
Wednesday and Thursday which will lead to mainly dry conditions and
a significant warming trend. Highs on Wednesday will mainly be in
the upper 60s north, to the lower 70s south and along the coast.
Then by Thursday and Friday, we should see widespread highs in the
70s, potentially even some readings in the lower 80s across southern
New Hampshire and southwest Maine. These temperatures will be well
above normal for this time of year, especially on Thursday.

A cold front then move across the forecast area on Friday, which
will lead to a cooling trend through the weekend. By Sunday, highs
will probably be back in the upper 50s to mid 60s.

The passage of the cold front will lead to a slight chance of
showers (20 to 30 percent) on Friday. The best chances will be over
the higher terrain and north but we will should at least see some
showers elsewhere. Some guidance then suggests that the next rain
maker will move in Sunday or Monday next week.
