440 pm est Wed feb 20 2019

Synopsis
Low pressure will move northeast through the great lakes and
into canada overnight lifting a warm front northeast across new
england into early Thursday. This front will be the focus for
snowfall and mixed precipitation before the temperature warms
up behind the warm front. A cold front will drop in from the
north Thursday afternoon bringing cooler weather back into the
region. High pressure moves in from the west Friday and exits to
the east on Saturday. Meanwhile the next storm system will be
developing in the southern plains and tracking northeast toward
the great lakes. It will bring another frontal system into new
england Saturday night into Sunday with another round of wintry
precipitation.

Near term until 6 am Thursday morning
440 pm update...

just a quick update to adjust a headline.

Previous discussion...

clouds are gradually thickening across the region early this
afternoon as a warm front approaches from the southwest. Radar
showing widespread returns across southern new england and
eastern new york but a majority of this not showing up in
surface obs as the very dry airmass in place across the region
is inhibiting northward progress. Main area of precipitation
well back to the southwest over the lower hudson valley into
south central new york. Will take some time to saturate this
airmass so only looking for occasional snow showers in southern
new hampshire from late this afternoon through the early evening
hours. Expect steadier precipitation to move into southern new
hampshire between 800 and 1000 pm and will overspread the
remainder of the forecast area by midnight or shortly after.

Have not made much in the way of changes to snowfall amounts and
still looking for 3 to 6 inches across most of central and
northern maine and new hampshire. Still expecting warmer air
aloft to penetrate into southern new hampshire and
coastal southern interior maine during the early morning hours
with precipitation changing to sleet and possibly a brief period
of freezing rain in southern new hampshire. This should hold
accumulations in the 2 to 3 inch in those locations. Expect low
temperatures to be reached during the evening before temps
become steady or slowly rising. Lows will range through the
teens in the north and lower to mid 20s south.

Short term 6 am Thursday morning through Thursday night
Snow and mixed precipitation will quickly end from southwest to
northeast Thursday morning as trough axis shifts east and
westerlys kick in behind a cold front. Expect clearing downwind
of the mountains during the morning hours and with colder air
lagging back to the west... Should see temps take a jump into 40s
in southern zones which should help melt off area roads. Farther
north clouds and snow showers will persist in the usual upslope
areas. Highs in the north will range through the 30s.

Looking for variable clouds in the mountains Thursday night
with evening snow showers. Remainder of the area will see partly
cloudy skies as high pressure begins building in from the west.

Lows overnight will generally range through the 20s.

Long term Friday through Wednesday
The global pattern stays fairly consistent over the next few
days with a large trough over the western conus. In the east a
series of waves will move through the ridge pushing more
precipitation through the region.

Friday and Saturday we have high pressure over the region. Sunny
skies and fairly moderate temperatures aloft will allow for
highs to reach into the 40s.

Friday night will see skies mostly clear allowing temperatures
to drop back into the teens. By Saturday night another
approaching system brings clouds to the region keeping
temperatures up overnight.

The next system continues our pattern with the main low
pressure tracking to our west through ontario and into southern
quebec. Once again this sets up northern new england to be in
the warm sector of the main cyclone and a mix of precipitation
types is expected. Aloft the infiltration of warm air is likely
and while timing differences between models are to be expected
at this time range all options put warm air into the region far
enough to push a mix through at least the foothills. At the
surface we see what is beginning to become an all too familiar
story. The departing high pressure will allow for cold air to
linger along the mountains and the potential for weak secondary
surface cyclogensis also suggests that colder air may hold on
longer at the surface. Have kept with these trends keeping
colder air longer at the surface while allowing the warm air in
aloft for yet another mixed precipitation event. Temperatures
uncertainty will likely decrease over the next few days as the
system forms to our west and for now have kept to a middle
ground for timing and temperatures.

Behind the system on Sunday night into Monday we see a cold
front cross the region with the cold air advection pushing in.

While the initial cold FROPA may actually increase temps briefly
across the interior western maine mountains as downsloping takes
over from the cold air damming in general temperatures will fall
from Sunday into Monday. Strong mixing on the backside of the
front will lead to gusty winds from Sunday night into Monday.

With a low level jet of up to 60kts there is some potential for
strong wind gusts, especially over the waters through Monday
afternoon.

Aviation 22z Wednesday through Monday
Short term... Ifr lifr ceilings vsby develop this evening from
southwest to northeast. BecomingVFR downwind of the mountains
by Thursday afternoon with areas of MVFR ceilings vsby in the
north.VFR Thursday night.

Long term... High pressure on Friday and Saturday will maintain
vfr conditions across the region. Low pressure approaching will
lower conditions to MVFR and then ifr as mixed precipitation
moves into the region on Sunday. Expect ifr to continue with
snow north and snow shifting to sleet and rain in the south. A
cold front will cross the region late Sunday or early Monday
with increasing westerly winds and improving ceilings.

Marine
Short term... Have issued sca's for late tonight through Thursday
night.

Long term... High pressure will cross the region from Friday into
Saturday. Low pressure will pass northwest of the waters on
Sunday brining widespread rain. A cold front will cross the
waters late Sunday into Monday bringing strong west
northwesterly winds with gale force likely and a few gusts to
storm force possible.

Tides coastal flooding
Storm surge of around a half foot will combine with high
astronomical tides on Thursday to produce minor coastal flooding
and splash-over at the time of high tide which occurs around
noon. A coastal flood advisory is in effect from 10 am to 200 pm
Thursday for coastal new hampshire and southwest maine.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
