.WHAT HAS CHANGED...
Issued a Coastal Flood Advisory for tonight`s high tide for
coastal areas from Portland and points south.

&&

.KEY MESSAGES...
1. Minor coastal flooding remains possible, especially during
the Monday morning high tide cycle.

2. Radiational cooling will keep low temperatures cold tonight
and especially tomorrow night as high pressure sits over the
area.

3. A relative warm up brings temperatures close to average
early to midweek. Then, another cool down is expected by late in
the week and into the weekend.

&&

.DISCUSSION...
KEY MESSAGE 1 DESCRIPTION...

High astronomical tides combined with between 1.5-2.0 ft of
storm surge from distant low pressure over the open North
Atlantic will bring total water levels to near minor flood stage
both tonight and Monday morning.

The tide is expected to rise near minor flood stage tonight,
but higher wave action (especially south of Portland) will
allow for some splashover and beach erosion across beaches in
southern NH/ME. A Coastal Flood Advisory was issued for
tonight`s high tide. Tomorrow`s high tide is expected to see
less wave action, but the water levels will be a little higher,
with splashover and minor coastal flooding impacts possible
along the entire coastline. Ice movement in marshier areas along
the coast could block some drains and create some ponding.


KEY MESSAGE 2 DESCRIPTION...

High pressure overhead tonight and Monday night should allow
for good radiational cooling conditions. Partly cloudy skies
will mitigate this concern tonight, though low temperatures are
still expected to bottom out in the single digits above/below
zero in most spots.

Conditions look to be mostly clear and very calm across the
area Monday night. Low temperatures are likely to be near or
below 0F across most of the interior, and can`t rule out some
localized double digit below 0F readings in the upper
Connecticut and Androscoggin River valleys (Littleton, Berlin,
Fryeburg being places most prone to colder temperatures).



KEY MESSAGE 3 DESCRIPTION...

A ridge of high pressure builds eastward early this week,
bringing a relative warm up to the region after an extended cold
stretch. While certainly not warm, temperature rise back to
near average for much of the week. Highs in the upper 20s to low
30s are expected south of the mountains through at least
Wednesday.

On Wednesday, a front approaches from the north, but is looking
more likely to wash out before crossing through New England.
This brings the chance for some snow showers across the
mountains late Wednesday. If the front doesn`t clear New
England, highs around freezing likely continue through Friday. A
stronger front then approaches late in the week, with another
shot of cold air more likely by this weekend.

the next cold front likely on Friday.
