Synopsis
Clouds and moisture from a low pressure area along the mid
atlantic coast will move north into the region today, with rain
showers developing across the north country this afternoon
and tonight. Rain showers will continue tonight and into
Wednesday. Expecting partly to mostly cloudy skies Wednesday
night. Thursday will see warmer temperatures with highs in the
70s under partly sunny skies.

Near term /through tonight/
As of 752 am edt Tuesday... Surface observations and radar
showing some very light sprinkles moving into southern vermont
at this time. This will work its way slowly northward, but will
run into somewhat drier air in the lower portion of the
atmosphere. Current forecast still looks good, so no major
changes have been made.

Previous discussion from 418 am edt Tuesday... Clouds and
moisture will be on the increase today from a low pressure area
along the mid atlantic coast. Bufkit forecast soundings show
fairly dry conditions in the lower portion of the atmosphere
today, so it will take a while to saturate the lower layers.

Skies should start out partly sunny today, with increasing
cloudiness the through the day. Expecting rain showers to
develop later this afternoon and continue into tonight. Have
gone with mainly chance pops for today and with likely or
categorical pops for tonight for rain showers.

Short term /Wednesday through Wednesday night/
As of 418 am edt Tuesday... Expecting rain showers to continue
into Wednesday morning as the closed upper low and the surface
low will be coincident with each other south of long island new
york Wednesday morning. This low will then move east and be over
cape cod Wednesday night. Expecting the north country to be
partly to mostly cloudy Wednesday night, but remaining dry.

Models showing upper ridge to build into the region by late
Wednesday night.

Long term /Thursday through Monday/
As of 420 am edt Tuesday... Not much change in the forecast but
overall active period during the long term. The period will
start off dry as rain showers associated with coastal low
continue to move east. Some lingering clouds may limit warming
over eastern vermont, but generally expect temperatures in the
70s.

Thursday night into Friday will have chance for showers and
possible thunderstorms that are expected to move west to east
across the north country as a long wave 500mb trough becomes
negatively titled over ontario, extending into the eastern great
lakes. Reflected at the surface, a front boundary will provide
the lift for these showers... Clearing the area by Friday night.

Heading into the weekend, a bermuda high looks to develop at
the surface and aloft. Several areas of vorticity at 500mb will
move from SW towards southern quebec and possibly impact the
north country through Saturday night.

On Sunday, canadian high pressure centered around james bay
will retreat north and east as strengthening closed surface low
moves northward from texas towards the western great lakes by
late Sunday. A warm front ahead of the low looks to bring more
showers by Sunday night. GFS and ECMWF still show differences on
evolution and track of this system, but strong low level jet
associated with cold front will create good moisture plume from
the gulf of mexico northward. Expect this cold front to move
into the north country sometime Monday. Overall expect this
system to be capable of producing heavy rainfall and strong
winds from tight pressure gradient and strengthening of low.

Also, thunderstorm activity expected ahead and along the cold
front as GFS indicates 500-1000 j/kg in the st lawrence valley
and negative lifted indices.

Aviation /12z Tuesday through Saturday/
Through 12z Wednesday... MainlyVFR conditions expected through
00z Wednesday. Satellite loop and surface observations showing
mainly high and mid clouds across the region at this time.

Expecting ceilings to slowly lower through the day. Bufkit
forecast soundings showing fairly dry conditions across the
region, so it will likely take a while to saturate the lower
levels of the atmosphere. Expecting any rain shower activity
will likely not reach the surface until this afternoon or this
evening. Expecting mainly MVFR conditions in rain showers after
00z Wednesday.

Outlook...

Wednesday:VFR/MVFR. Chance shra.

Wednesday night:VFR. Slight chance shra.

Thursday:VFR. No sig wx.

Thursday night:VFR. Slight chance shra... Tsra.

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.
