Area Forecast Discussion
National Weather Service Gray ME
1104 AM EDT Mon Sep 21 2020

.SYNOPSIS...
Mainly dry weather continues through mid week. Our cooler than
normal temperatures will moderate with above average values
expected by the second half of the week. Hurricane Teddy will
remain well offshore Monday before passing east of our region on
Tuesday. High pressure will follow for the foreseeable future.
Chances for widespread rainfall remain low through the end of
the week.

&&

.NEAR TERM /TODAY/...
1100 AM...After conferring with neighboring offices and local
emergency management, a coastal flood advisory has been issued
for coastal York and Rockingham counties with minor flooding and
signifiCant splash-over expected with continued strong surf.

945 AM...Another round of minor tweaks to temperature and dew
points this morning according to trends with little change to
the forecast. Expired Frost/Freeze products.

630 AM...Minor ESTF update to reflect the current mesonet in
near term grids.

Prev Disc...
At 06z...a sprawling 1038 millibar high was centered over
northern New England. GOES infrared imagery showed clear skies
across the region. I expect we'll see some patchy stratus and fog
develop over a few interior valleys during the next few hours.
Otherwise...after another chilly and frosty start temperatures
should rebound into the lower and mid 60s under bright sunshine.
The gradient will be relatively light today with the high
center parked nearby. The light northeast flow should turn
onshore by afternoon near the coast. I adjusted the dew points
down by several degrees relative to the machine guidance for the
midday and afternoon hours...resulting in slightly lower
minimum relative humidity values.

&&

.SHORT TERM /TONIGHT THROUGH TUESDAY/...
For tonight...a clear start to the night along with light winds
under the surface high. However...an offshore impulse will
begin interacting with Hurricane Teddy and help pull the storm
back to the west. The gradient will begin to increase over our
coastal and eastern zones and we'll see a bit more wind there as
the night progresses along with a few high clouds. It'll be
another cold night with many inland communities dropping to near
or below freezing. On Tuesday...the gradient will continue to
increase as Teddy tracks well offshore to our east. It'll be a
breezy day with northerly winds of 10 to 20 mph with a few
higher gusts. With the exception of a low chance of showers near
midcoast Maine...it'll be another dry day. The low relative
humidity values...gusty winds...and mild temperatures will
likely result in an elevated fire danger.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
500 MB pattern across NOAM and environs, which has been fairly
weakly amplified over the last few days, gradually transitions
to a more amplified patter through the weekend and into next
week. PArt of this is due to Teddy, as it will help amplify
troughing to our N and E, while another trough digs equatorward
over the wrn CONUS. Ultimately, once Teddy passes and helps
develop that trough to the NE, we will actually see warmer ridging
over the area late this week and thru the weekend, with little
if any precip expected.

Teddy makes its closest pass to New England Tue night, when it
is forecast to SE of Yarmouth, NS and turning to the NE. Fairly
tight pres gradient between it and strong high to the N will
produce some gusty N-NW winds Tue night. Still, given timing /at
night/, and distance from the storm would expect sustained
winds of 10-15 mph with some gusts of 25-30 mph in ME, and less
than that in NH overnight, with lkly very little wind as far W
as the CT vly. Also given the dry airmass, any precip will
lkly be limited to far ern zones, and even this shouldn't amt
to much, if anything, based on the current track. Persistent
mixing overnight in neutral advection, and 850 temps close to
10C should make for a warmer than we're used to with lows in the
low to mid 40-s mtns, to the low 50s in srn NH and on the
coast.

Wed will see Teddy heading NE into Newfoundland, and any rain in
the east will be ending, but NW winds will persist thru the day
with gust to around 25 mph or so, and clearing skies in the
morning. A well mixed boundary lyr should produce highs in the
upper 60s N, to the mid 70s in the south. Prime downslope areas,
like Portland, could see temps near 80.

500 Mb ridging should persist through the end of the week into
the weekend, although a very weak front will move through on
thu, but should have little effect o sensible other than a
period with a few more clouds. Highs Thu ahead of the front
will once again range from upper to 60s to mid to upper 70s.

FRiday through Sunday look mainly sunny and dry with highs in
the upper 60s to mid 70s, and overnight lows in the mid 40s to
low 50s. Will likely see some sea breeze developing over the
weekend which could keep the coast a bit cooler. The next chc
for rain isn't until Sunday night or Monday.

&&

.AVIATION /15Z MONDAY THROUGH FRIDAY/...
Short Term /Through Tuesday/...Lcl brief LIFR conditions psb
over northern and western NH in patchy valley fog btw 09 and 12z
today and again 09 to 12z tues. Otherwise, VFR conditions
expected.

Long Term...Mainly VFR Tue night through Friday. Some N-NW wind
gusts to 25 kts or so possible at KPSM/KPWM/KRKD/KAUG Tue night
into Wed as Teddy passes to our east.

&&

.MARINE...
Short Term /Through Tuesday/...SCAs will remain for the outer
waters. Long period swell from Hurricane Teddy will continue to
build through the period. By Tuesday...winds will also be
increasing as the gradient tightens over the waters with a Gale
Watch issued starting Tuesday afternoon for the outer waters.

Long Term...Strongest winds from Teddy will be Tue night, and
gales will possible especially E of Casco Bay. Swell from Teddy
will also help push seas to 10-15 ft Tue night as well. Seas
diminish Wed and Wed night, with SC winds holding thru the day
on Wed.

&&

.FIRE WEATHER...
Lighter winds are expected today along with onshore winds near
the coast. However...minimum relative humidity values should
still average between 25 and 30 percent in most areas. We'll see
good recovery in relative humidity again tonight. Tuesday will
be a much breezier day as Hurricane Teddy passes well offshore.
The low relative humidity values...gusty winds...and mild
temperatures will likely result in an elevated fire danger.

&&

.TIDES/COASTAL FLOODING...
We will continue to be near the top of our astronomical tide
cycle over the next couple days.

Several consecutive high tide cycles may have splash-over as
large, long period swells reach the beaches. Coastal headlines
may need to be expanded down the coastline with time, perhaps
through as late as Wednesday morning.

The greatest modeled storm surge arrives Tuesday with over two
feet suggested by the ETSS model. These values will likely be
due to the large swell reaching the coast and not the wind flow.
Winds are expected offshore, out of the north during the period
which is not normally an indicator for coastal flooding. In any
case, the Tuesday tides will need to be monitored for potential
minor, with possibly pockets of moderate, coastal flooding
depending on the track of Teddy.
