Synopsis
Low pressure will move over the north country today leading to
widespread light rain and mountain snow. Higher elevation
locations will see the potential for 3 to 6 inches of snow with
a dusting to an inch possible in the valleys. Temps will remain
below normal through the rest of the week before a warming
trend begins over the weekend. Coming out of the weekend we
should see near normal to slightly above normal temperatures
along with dry conditions and plentiful sunshine.

Near term through Friday
As of 352 am edt Thursday... An upper level trough will swing
through the north country today with a surface low pressure
tracking generally south of the area. Other than a few light
mountain snow showers the rest of the evening will remain
relatively quiet. As we move into the daylight hours the upper
level trough will move over the region and low level moisture
will increase as the flow turns more northwest. This will lead
to precip lifting north and becoming scattered across the north
country. The best chance for prolonged precip will be in the
mountain areas but all sites should see measurable rain or snow.

Snow levels during the day will be in the 1000-1500ft range
during the day and then will fall to the valley floors during
the evening hours Thursday. So a dusting to an inch of snow will
be possible in elevations less than 1000 ft and in the high
elevation sites above 2500 feet will have the potential for 3-6
inches of snow with the potential for the mt mansfield stake to
get close to 100 inches by Friday afternoon.

Because we'll be dominated by the upper level trough through the
rest of the week, we'll continue to be well below normal with
highs in the low to mid 40s. Temps overnight will be just below
normal with lows in the upper 20s to low 30s.

Short term Friday night through Sunday
As of 352 am edt Thursday... A deep-layer trough will be
departing to our north and east across the canadian
maritimes newfoundland, with a prevailing NW low-mid level flow
in place across the north country. Should see lingering
rain higher elevation snow showers generally ending during the
first half of Friday night (30-40% pops early) with decreasing
moisture cyclonic flow. Some partial clearing expected by
daybreak Saturday with overnight lows generally in the upper 20s
to lower 30s.

The weekend generally looks seasonably cool and dry with high
pressure across the great lakes gradually building eastward.

Should see partly sunny conditions with highs in the mid-upr 40s
on Saturday, followed by temperatures moderating into the upr
40s to lower 50s with mostly clear conditions and lighter nw
winds on Sunday. Precipitation is not expected Saturday or
Sunday.

Long term Sunday night through Wednesday
As of 352 am edt Thursday... A deep-layer ridge will build
across the northeastern CONUS early next week, finally setting
up a warming trend for the region. Should see high temps in the
mid-upr 50s for Monday, and into the low-mid 60s for valley
locations on Tuesday (normal high for btv is 57f). Next northern
stream shortwave trough expected to arrive on Wednesday per 00z
gfs. Some indication of phasing with a SRN stream system from
the carolinas, which would have implications for overall
rainfall amts. The 00z ECMWF has a similar synoptic pattern with
possible phasing, though the evolution is about 18-24hrs
slower. Too early to say, but a stronger, phased system with
better influx of moisture would potentially have implications
for moderate to heavy precipitation at the end of the period.

We'll be monitoring this potential. Anticipate high temperatures
remaining near 60 degrees for highs on Wednesday.

Aviation 08z Thursday through Monday
Through 06z Friday... GenerallyVFR to MVFR flight conditions
will prevail with periods of ifr ceilings and visibilities at
slk. Widespread light rain and snow will move across the north
country. The best chance for prevailing precip will be in the
afternoon generally after 21z. Winds will generally be less than
10 kts through the period becoming west to northwest after 18z.

Outlook...

Friday: mainlyVFR, with areas MVFR possible. Likely ra, chance
sn.

Friday night: mainlyVFR, with local MVFR possible. Chance shra,
chance shsn.

Saturday: mainlyVFR, with local MVFR possible. No sig wx.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
