1036 am edt Thu apr 27 2017

A ridge of high pressure aloft will be over the north country
today and early tonight, with high temperatures today in the 70s
to around 80 from western vermont to northern new york. High
temperatures will be mainly in the 60s to lower 70s over eastern
and northeast vermont today. A frontal system will move into
the region after midnight tonight bringing a a chance of rain
showers to the region and a slight chance of thunderstorms.

There will be a chance of showers Friday morning, but skies will
become mostly sunny by Friday afternoon.

Near term /through Friday/
As of 1033 am edt Thursday... Update included to increase clouds
across our central/eastern sections and over the slv where low
level clouds and fog are persisting. These clouds have huge
impact on temps and have tried to capture this into our hourly
temp grids. Current obs show mss only in the lower 50s ATTM with
overcast skies at 300 feet... While potsdam has sunny conditions
and temps warming into the mid/upper 60s. Expecting temps will
jump quickly once the low clouds burn off by midday.

Otherwise... Low level southeast flow will keep clouds and cooler
temps across eastern sections today with highs only in the
mid/upper 60s. Best weather with the warmest temps will be
eastern side of the cpv with highs upper 70s to lower 80s.

Previous discussion from 424 am edt Thursday... An upper ridge
will be over the region today, with skies becoming partly to
mostly sunny. However, a low level temperature inversion over
eastern and northeast vermont will keep low clouds in there
through this morning before skies become partly sunny this
afternoon. Areas of fog over the adirondacks and the saint
lawrence valley early this morning will burn off later this
morning, with skies becoming partly to mostly sunny with highs
in the 70s to lower 80s expected from the champlain valley
westward to the saint lawrence valley. Clouds east of the
western slopes of the green mountains will keep temperatures
cooler there today with highs mainly in the 60s to lower 70s.

Tonight, a weakening frontal system will approach the region
from the eastern great lakes and will bring rain showers to the
north country after midnight tonight. Have also continued to
mentioned a slight chance of thunderstorms late tonight, as
showalter indexes slightly negative, suggesting some elevated
convection possible. Lows will be mainly in the 50s tonight.

Showers to linger into early Friday morning, with skies becoming
mostly sunny by Friday afternoon. High on Friday will be in the
upper 60s to mid 70s.

Short term /Friday night through Saturday night/
As of 520 am edt Thursday... Clouds increase Friday night with
increasing chance of showers as bits of energy approach during
the short term. North country remains in wsw to ese flow at
500mb with bermuda high in place and northerly trough trekking
across hudsons bay and extending southward towards the great
lakes. Not a whole lot of dynamics or moisture associated with
energy moving over the northeast. Strong upper level jet
(120-140kts at 250mb) looks to remain to our north but could
help provide lift for some showers late Friday night into

Canadian high pressure at the surface along with building ridge
axis aloft expected to provide dry Saturday afternoon and night.

Long term /Sunday through Wednesday/
As of 520 am edt Thursday... Active pattern continues to be the
trend in the long term.

High pressure over the north country will be interrupted by
Sunday afternoon as warm front brings clouds to the region and
increasing chance for showers... Mainly late in the day for
portions of northern ny. Associated closed surface low will
continue to strengthen as it heads towards the central great
lakes. Warm front could continue to bring showers Sunday night
into the first half of Monday, but models differ on exact
location of where the warm front sets up... Remaining north of
the international border or over northern portions of the
forecast area. Either way, continued WAA in southerly flow will
result in moist and warm conditions. Both GFS and ECMWF show a
dry slot may move into the region Monday afternoon allowing some
sunshine from breaks in clouds to warm temperatures into the
70s. Southerly jet of 40-50kts at 850mb develops resulting in
breezy conditions across the champlain valley at least.

Front still looks to moves from west to east across the north
country Monday night into early Tuesday. Slight chance of
thunderstorms still possible with weak instability, but
overnight timing not as favorable. Widespread rain of 0.5-1"
should not cause any significant hydro problems on rivers.

Main 500mb trough passes over the region Tuesday, keeping low
level moisture and potential for showers. Developing shortwave
around the great lakes region will keep chance for showers
through the end of the period as we remain under westerly flow.

Aviation /15z Thursday through Monday/
Through 12z Friday... A ridge of high pressure will be over the
region through the period. However, rather widespread MVFR
ceilings across eastern and northeastern vermont as of 11z
Thursday, as moisture is trapped below a low level temperature
inversion. Expecting MVFR ceilings in these locations til 18z
Thursday, and then becomingVFR. Also, widespread ifr/lifr in
ceilings and fog across the adirondacks and saint lawrence
valley in northern new york at this time. Expecting conditions
to becomeVFR in these locations by 14z Thursday. Expecting
rain showers to spread across the region between 06z-10z as a
frontal system moves into the region after 06z Friday.


Friday:VFR. Breezy. Slight chance shra.

Friday night:VFR. Slight chance shra.

Saturday:VFR. Chance shra... Tsra.

Saturday night:VFR. No sig wx.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
