What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Shower chances will return on Tuesday as a weak low pressure
system moves through the area followed by a cold front
Wednesday. Thereafter, high pressure will bring seasonably mild
and dry weather on Thursday, then warmer on Friday.

Near term through Tuesday night
As of 729 pm edt Monday... A wonderful evening continues across
the north country with mild temperatures and mostly clear skies.

No significant changes made to current forecast, just updated to
increase high clouds quicker and match hourly grids with crnt
obs. Vis satl pic shows mid upper level clouds increasing from
west to east across our CWA this evening, which should make for
an outstanding sunset over the lake. Otherwise, these clouds
will continue to thicken overnight with areas of light rain
arriving by Tuesday. Lows mainly in the mid 40s to mid 50s range
tonight with light winds becoming south southeast as low pres
approaches the region on Tuesday.

Today's beautiful weather continues through this evening with
high pressure slowly sliding by just to the south. Clouds will
increase overnight as a weak low pressure system approaches from
the west. This increasing cloud cover as well as south flow
developing around the back of the high will keep temperatures in
the 45-55 range for much of the north country tonight.

The aforementioned low pressure system will move across our area on
Tuesday. Warm advection out ahead of this system will bring another
shot of rain to the region. Rain won't start first thing in the
morning as it will take a bit for things to saturate enough for it
to reach the ground, but do anticipate rain to spread from west to
east starting mid-morning or so, reaching the ct river valley by
early afternoon. The rain will persist into the evening hours until
the low moves to our east. Winds will then turn northwest, ushering
in drier air. Influx of cloud cover and rain will keep temperatures
down on Tuesday, close to or just below normal. This in turn will
help to limit instability during the day. However, note that there
will be some elevated instability Tuesday evening as the low moves
through, which may be enough for a rumble of thunder or two. Spc's
day 2 outlook does have south-central vt included in the general
thunder area, but as the best instability will remain to our south,
have not included mention of thunder in the forecast at this point.

Short term Wednesday through Friday
As of 338 pm edt Monday... No real big changes from the previous
forecast thinking for the middle to end of the work week with
models remaining very consistent. Overall big picture highlights
an upper trough with some modest shortwave energy tracking
through me nh skirting our northeast zones on Wednesday,
followed by high pressure for Thursday and Friday. Outside of a
few showers and perhaps an isolated thunderstorms across
northern areas Wednesday, the rest of the week will be dry with
temps ranging through the 70s on Wednesday, cooler in the upper
60s to low 70s for Thursday, and significantly warmer in the
upper 70s to low 80s on Friday.

Long term Friday night through Monday
As of 338 pm edt Monday..Still a ton of uncertainty for the
holiday weekend with little model run to run consistency. Latest
gfs and canadian gem show a frontal zone and digging upper
trough over central quebec dropping southward into the northeast
Friday night through Saturday, with an upper level ridge and
surface high pressure building in for Sunday and Monday. This is
in stark contrast to previous runs, while the ECMWF has
remained more consistent showing the trough well farther
northeast over the canadian maritimes. The ECMWF still
highlights a frontal zone moving over the region Friday night
into Saturday, but without the trough to kick it out, wetter and
warmer conditions prevail through the weekend. Moderate
forecast confidence at this point that we'll see some rainfall
Friday night into Saturday, but beyond that confidence is very
low. Stay tuned.

Aviation 00z Tuesday through Saturday
Through 00z Wednesday...VFR conditions will prevail this
evening and overnight with just a gradual increase in mid-upper
level clouds (aoa 12kft). These clouds should preclude any fog
formation at the TAF locations overnight. Weak low pressure
advancing eastward from the great lakes will bring scattered
light rain showers, mainly 14-23z Tuesday at all TAF locations.

May see some intervals of MVFR ceilings with hir trrn obscd
during the shower activity, especially Tuesday afternoon. Winds
will be relatively light overnight, becoming s-sw 6-10kts during
the daylight hrs Tuesday.

Outlook...

Tuesday night: MVFR ifr conditions possible. Chance shra.

Wednesday:VFR. Slight chance shra, slight chance tsra.

Wednesday night:VFR. No sig wx.

Thursday:VFR. No sig wx.

Thursday night:VFR. No sig wx.

Friday:VFR. No sig wx.

Friday night:VFR. Chance shra.

Saturday: mainlyVFR, with areas MVFR possible. Chance shra.

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.
