area forecast discussion... Updated
national weather service gray me
936 pm edt Thu apr 25 2019

Synopsis
Low pressure will approach from the west tonight and finally
sweep across the region Saturday. This system will bring more
rain to the region Friday into Saturday, and will likely cause
flooding in some areas. Another system will pass south of the
region late Sunday and yet another one for early next week.

Near term through Friday
935 pm update...

have adjusted temperatures slightly to increase temperatures
over a warmer corridor still over southern nh and interior
maine, which will continue to fall off gradually. Otherwise no
changes for this update.

650 pm update...

statocu continues to erode to the northeast across northern
reaches of nh and the western me mountains. Some cirrus is
moving across southern nh at this time, but in between there is
mostly sunny skies still. It will take time for the moisture to
return ahead of the next system, so precipitation timing towards
daybreak still looks good, with heftier cloud cover arriving
overnight. Temperatures in the 60s and 50s will drop into the
30s and 40s ahead of the rain. The forecast was updated slightly
to account for current conditions and the above forecast.

Previous discussion...

stubborn stratocu across central and northern zones is gradually
clearing from south to north, but will still take a while to do
so across the mountains. Otherwise, a mostly clear start to the
evening is expected across southern zones before high clouds
begin streaming in from the southwest late in the evening and
overnight. Light rain should begin to fall across western and
southwestern zones just prior to dawn.

Short term Friday night
Unfortunately, heavy rain is once again in the cards for later
Friday and Friday night as moisture-laden low pressure
approaches from the west. Forcing for ascent will increase later
tonight and early Friday allowing for precipitation to overspread
the forecast area Friday morning. A southeasterly LLJ just above
the boundary layer really gets cranking Friday night and this is
when the heaviest rainfall is expected with pwats possibly
approaching 1.3 inches. A multi-model consensus is for a
widespread 1-1.5 inches of rain. However, strong southeasterly
upslope flow into the whites and portions of the western me
mountains will enhance rainfall rates and amounts on south
through southeast facing slopes. Blended in mesoscale model data
to account for this, allowing for some 3 inch amounts there.

This will undoubtedly cause rivers to rise once again, with
additional flooding expected. Therefore, a flood watch has been
issued for the most flood prone forecast zones. At this time, it
appears as though the LLJ will keep strong winds at bay by a
strong low level inversion, so little in the way of wind issues
are expected at this time.

Long term Saturday through Thursday
As the surface low trough move off to the east, colder air will
move in behind the system. Beneath the upper low on Saturday we
could still see some lingering showers especially in northern
areas.

The next wave tracks by to our south over southern new england
Sunday and Sunday night. The precipitation associated with this
will likely spread across the southern portion of new hampshire
and maine Sunday afternoon and evening. Temperatures aloft are
actually cold enough for snow on the northern edge of the
precipitation region, so precipitation type will be dependent
on surface temperature. Cold advection during the day Sunday
will lower the temperature by Sunday evening so a change to snow
is possible even toward the coast. Accumulations look unlikely
at this point, but a few flakes in the air would be notable.

High pressure moves across on Monday with a break in the
precipitation. There are indications that another wave will
track by to our south on Tuesday. This will be similar to Sunday
as we will be on the northern edge of any precipitation with
temperatures aloft cold enough for snow if low level
temperatures are cold enough.

Aviation 02z Friday through Tuesday
Short term through Friday night ...VFR conditions tonight give
way to MVFR Friday morning and then ifr afternoon in rain.

Heavy rain likely Friday night with lifr conditions and llws
likely.

Long term... Conditions improve on Saturday withVFR returning
first to the southwestern part of the area. MVFR conditions and
showers may linger in the mountains. There will be a window of
vfr conditions Saturday night and early Sunday, but the next
system brings a return to MVFR or ifr conditions Sunday
afternoon and evening with rain or snow possible mainly in
southern areas. This should clear up by early Monday morning.

Marine
Short term through Friday night ... Light winds and seas
tonight, but they do increase ahead of approaching low pressure
Friday afternoon and Friday night. A SCA has been issued for all
waters, but gales could be a possibility on the ocean waters at
times Friday night and that potential will be monitored.

Long term... Winds shift to the west on Saturday with gusts to 30
kt before diminishing Saturday evening. Low pressure passing by
to the south of new england Sunday night will bring a shift to
northwest winds which could again reach advisory levels before
diminishing on Monday.

Hydrology
A widespread 1-1.5 inches of rain is expected Friday and Friday
night. However, south and southeastern facing slopes of the
white mountains and portions of the western me mountains will
see an enhancement to the rainfall with some 3 inch amounts
possible. Since rivers are already running high we expect
renewed rises, especially Friday night and Saturday. Therefore,
a flood watch has been issued for the most flood- prone zones at
this time. With snowmelt being a minimal contributor at this
point in the year, we think mainly minor flooding will be the
theme.

Gyx watches warnings advisories
