1214 pm edt Sun may 20 2018

Synopsis
A warm front bisected the region this morning, bringing a
period of rain. It will be followed by a cold front later this
morning. High pressure will build in from the west Sunday night
and will pass out to sea south of new england Monday. Weak low
pressure will pass south of new england on Tuesday. A cold front
will drop south through the region Wednesday. Weak low pressure
tracks along the international border late Thursday into
Friday. A frontal system tracks into the area for the weekend
bringing widespread showers.

Near term until 6 pm this evening
1210 pm... A quick update to fine tune the tining of the showers
and the temps, based on current obs. Not much change to forecast
for this afternoon though, and showers should be done by ~18z.

Also, limited thunder to just SE nh, and even there chc is
slight, probably the best chc will be offshore.

10 am... Based on latest obs radar meso models, looks like any
showers associated with the front will move thru between now and
about 2-3 pm. I added the slight chc for thunder, especially
across SW me and SRN nh as there seems to be some decent
moisture convergence developing in this area, which could help
enhance the lift, and support some updraft development.

Otherwise should see winds shift to the wnw behind the front
this afternoon with some clearing during the mid-late
afternoon. Highs should still make it into the low to mid 70s
in many spots, but highs will be closer to 70 on the coast and
in the mid to upper 60s in the mtns.

7am update...

early morning temperatures have been on the increase as wind
flow has shifted to the southwest and we have lost the influence
of the cold gulf of maine. Showers have already begun moving
through northern areas in scattered fashion. Expect a bit more
coverage of this as the front arrives.

Original discussion...

cold front will move through the region today, with a few widely
scattered showers possible before it arrives, and a few more
focused ones arriving with the front. There is an outside chance
for a rumble of thunder, but this likelihood is too small to
mention in the forecast, and no severe weather is expected. It
will start off cloudy, but should see some clearing behind the
front as dry air pours in. Temperatures warm into the 70s to
even near 80 in southeast new hampshire.

Short term 6 pm this evening through 6 pm Monday
Dry air continues to pour in behind the cold front tonight with
a clearing sky. Temperatures drop into the 40s for most areas,
30s for the colder northern valleys. Monday will be drier but
still warm, even though we are behind the cold front. Good
mixing on a northwest wind will bring winds of 10 to 20 mph and
temperatures warming into the 70s again.

Long term Monday night through Saturday
Mostly zonal flow will dominate for Monday and Tuesday followed
by a large scale trough dipping out of canada for the midweek
period. Increasing heights are expected for the end of the
week.

On Tuesday a warm front will lift NE into new england, followed
by a cold front for Wednesday. A backdoor front settles in for
the weekend. Temperatures during the week will range from the
70s and 80s for southern and central nh and the coastal plain of
maine to the 60s across the mountains for highs. Lows will
range from the upper 30s far north to the 50s south and west,
precipitation increases Tuesday afternoon into Wednesday along
the cold front. QPF will be scattered and light in nature.

Mountain showers will be possible Thursday and Friday with
enough short wave energy passing by to produce weak convection.

The next good widespread rain event occurs over the weekend with
the backdoor front and associated upper level energy.

Aviation 16z Sunday through Thursday
Short term... Although conditions start the day ifr or lifr for
much of the coastal plain, we should see some improvement in the
ceilings through the morning, generally to MVFR by noon. A cold
front moves through this afternoon, bringing a shift to
northwest winds and clearing. Clear conditions continue into
Monday.

Long term...

tue - thu... Variable MVFR in -shra, especially across the
mountains, as a cold front crosses the region.VFR conditions
developing late Wednesday into Thursday.

Marine
Short term... Small craft advisory continues for winds and seas
today into this evening. Should see winds diminish today as the
front moves through, and seas subsiding by evening.

Long term... A brief increase in winds is expected Tuesday and
Wednesday as a frontal system passes through the region. Again,
winds should stay below SCA criteria. On Thursday winds and
seas will possibly reach SCA criteria.

Fire weather
After starting the day moist with clouds and showers, a cold
front will begin ushering in drier air this afternoon. Dry air
will be in place on Monday with a northwest wind of 10 to 20
mph. It is possible that we could approach borderline red flag
warning criteria, though confidence is not great and recent
rains might diminish this threat.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory until 10 pm edt this evening for anz150-
152-154.
