Synopsis
Low pressure will depart the region this evening bringing the
snow to an end. High pressure builds eastward into the region
for the rest of the week and into the weekend with a return
southwest flow bringing warmer temperatures by the weekend. A
storm system may affect the region early next week with mixed
precipitation and rain.

Near term until 6 am Thursday morning
1000 pm update
flurries are winding down in midcoast areas of maine late this
evening and skies are clearing over western new hampshire.

Expect clearing skies downwind of the mountains through midnight
while clouds and a few flurries continue in the north. Have
adjusted temp TD sky and pop grids to reflect latest obs and
expected trends. No major changes plan for the current forecast.

Prev disc...

700 pm update... Quick update to drop expired headlines for
warnings and advisories. Left over flurries currently exiting
southeast new hampshire and lingering flurries over southern
maine will be ending through midnight with no further
accumulation expected. Expect clearing skies downwind of the
mountains by midnight or shortly after. Have updated area pops
based on current radar trends. Aside from a few temp and td
tweaks no other changes planned to current forecast.

Prev disc...

530 pm update... Have adjusted pops just a little bit for the
next couple of hours based on latest trends in radar imagery.

The hrrr has been doing a pretty good job with the light
snowfall progressing over our forecast area early this evening.

Have therefore stuck with hrrr forecast for the departure of the
accum snow this evening with the departure of a short wave
trough and weakening of an inverted sfc boundary. Advisories and
warnings remain up until 7 pm and should be able to expire on
time. Up to an additional inch is possible through that time.

Previously...

low pressure will gradually move away from the region this
evening bringing an end to the snow early on. Winter weather
advisories are in effect for the southern half of nh until 7 pm
with winter storm warnings and advisories continuing for
portions of me until that time also. A short wave trough will
swing across northern new england late this afternoon and early
evening allowing much the advisory and warning area to pick up
an additional inch or two of snow. This will make the evening
commute slippery in most areas. Some spotty freezing drizzle may
occur as well for a short period of time early this evening, but
that looks like a low probability at this time. Clearing is
expected to occur in the wake of the short wave trough later
tonight downwind of the mountains.

Short term 6 am Thursday morning through Thursday night
Thursday looks to be a fair weather day with seasonable
temperatures. However, the northern whites and a portion of the
western me mountains will probably see upslope snow showers
especially in the morning. Another short wave trough will cross
the region Thursday night with an increase in clouds. Some snow
showers may occur as well if the column moistens up
sufficiently.

Long term Friday through Wednesday
Zonal flow will replace the trough which has been plaguing the
east coast by the end of the week. A more southwesterly warm
air advection pattern develops for the weekend and into early
next week as low pressure detaches and forms along the base of
southern stream troughing over the southern and central plains.

Weak upslope snow showers will be possible over the white
mountains and the western maine mountains Friday through
Sunday with persistent but non-significant short wave energy
passing by. Precipitation then spreads east with time on Monday
into Tuesday. Coastal locations may see rain with the
possibility of mixed wintry p-types as an eastward moving cold
front brings lifting for ascent towards low pressure pivoting
up the eastern seaboard. This will allow cooler air back in with
temperatures dropping back towards normal values by next
Wednesday.

Aviation 03z Thursday through Monday
Short term through Thursday night ... MVFR to ifr conditions
early this evening in snow and low clouds will give way toVFR
conditions after midnight tonight through Thursday.

Long term... MainlyVFR conditions across the region Friday
through Sunday. There will be a chance of light mountains snow
showers MVFR ceilings for mainly hie and possibly leb during
this time. Widespread lower ceilings and visibilities in
possibly mixed wintry precipitation late Monday night as low
pressure heads towards new england.

Marine
Short term through Thursday night ... Marginal SCA for seas
remains in effect for the ocean waters for tonight into early
Thursday morning.

Long term... Waves and winds increase to near SCA conditions
late Friday into Saturday in gusty SW flow before dropping off
once again.

Hydrology
River flood warning for the kennebec has been reissued as jammed
up ice has caused the river to rise just above flood stage
again. It is expected to go below flood stage Thursday
afternoon.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory for hazardous seas until 7 am est
Thursday for anz150-152-154.
