Synopsis
Fair weather with mainly clear skies for a couple more days as
high pressure moves over the region. It will be chilly again
today and tonight then temperatures will warm to seasonable
levels Wednesday with above normal readings for the rest of the
work week into the weekend. Our next chance for any showers will
come Thursday afternoon and night as a cold front approaches
and moves into the area.

Near term until 6 pm this evening
Sprawling surface high centered over great lakes will gradually
shift eastward today. While aloft, the upper level trough axis
will finally move off to our east this afternoon with heights
beginning to rise.

Highs today will be a bit lower than Monday with readings from
the upper 20s to lower 40s, around 10 degrees below normal. Good
news is winds will be rather light and we will have abundant
sunshine. Relative humidity levels will be dry today as dew
points remain very low in the single digits with some below zero.

Short term 6 pm this evening through Thursday night
It will be chilly tonight as the center of the surface high is
expected to pass directly over the region early Wednesday
morning plus some weak ridging occurs aloft. With clear skies
and light variable to calm winds temperatures are expected to
bottom out around 15 degrees below normal mainly in the teens.

Single digits readings are expected across much of the western
adirondacks and across the higher terrain of the southern green
mountains.

Moderating temperatures as the high shifts off the coast
Wednesday afternoon and a southerly return flows develops.

After our cold start, temperatures are expected to rebound to
seasonable levels in the afternoon with highs mainly in the 40s
with some lower 50s up the immediate hudson river valley into
the capital district.

It will be even warmer Thursday with broad southwesterly flow
across the region between the departing high and an approaching
trough and cold front despite an increase in clouds. Expecting
highs in the 50s with mid and upper 40s above 1500 feet. Chances
for rain showers are expected to move into the northwestern
portion of the local area during the afternoon as a low level
jet moves in and heights begin to fall. Chances for the showers
will spread across the rest of the area at night with the best
chances to the north and west of the capital district closer to
the upper level support short wave as it pass across eastern
canada. Mild night with lows only in the 30s to lower 40s.

Long term Friday through Monday
Upper level flow pattern Friday will be dominated by an anomalously
strong upper low centered over hudson bay. Fast zonal flow along the
southern periphery of this low over the northern tier of the conus
will become highly amplified by the weekend. This will occur as
northern stream energy along the southwest flank of the upper low
merges with energy ejecting out of the central plains. The result
will be a deep positively tilted trough over the western great lakes
Saturday, pivoting through the northeast and acquiring a negative
tilt on Sunday.

Friday Friday night, a few light showers cannot be ruled out as the
washed out front returns north as a warm front. Any precipitation
looks to be light and spotty with an absence of upper level forcing.

Another seasonably mild day is expected with forecast high
temperatures possibly around 10f above normal.

Saturday into Saturday night, elongated surface low will be
developing along a sharp baroclinic zone associated with the leading
edge of the approaching upper trough. Precipitation is expected to
be widespread along and to the cool side of the baroclinic zone.

Consensus puts the boundary and associated precipitation mainly west
of our area Saturday, putting much of the forecast area into the
warm sector. We could be looking at a very mild day assuming the
boundary stays west, with strong southerly flow in the warm sector.

We still do have chance pops over much of the forecast area due to
uncertainty with the position and speed of the boundary, and even
likely pops over portions of the western adirondacks as model
consensus favors the precip reaching there late in the day. Most
probable time for precipitation associated with this system is
Saturday night into Sunday, although there is still
considerable uncertainty with the timing. P-type looks to be
mainly rain, although if the trough acquires a negative tilt
earlier than current consensus (a la the 12z.25 ecmwf), we could
see rain changing to snow, particularly north and west of the
capital district. Temperatures will crash behind the sharp
boundary Sunday into Sunday night, returning near or a bit below
normal. As the trough shifts east, high pressure is forecast to
build in for Monday, leading to a dry but seasonably cool day.

Aviation 12z Tuesday through Saturday
High pressure will continue to build into the area through the taf
period, resulting in clear skies. Winds will be from the north to
northwest throughout the period, increasing to around 10 kt with
some gusts near 20 kt late this morning, and decreasing to less than
10 kt again around sunset.

Outlook...

Wednesday night: no operational impact. No sig wx.

Thursday: low operational impact. Breezy no sig wx.

Thursday night: moderate operational impact. Chance of shra.

Friday: low operational impact. Slight chance of shra.

Friday night: moderate operational impact. Chance of shra.

Saturday: moderate operational impact. Chance of shra.

Saturday night: moderate operational impact. Likely shra.

Sunday: moderate operational impact. Chance of shra.

Fire weather
Minimum relative humidity values mainly in the 20s this afternoon
and again Wednesday afternoon.

Fair weather with mainly clear skies for a couple more days as
high pressure moves over the region. Our next chances for any
showers will come Thursday afternoon and night as a cold front
approaches and moves into the area.

Hydrology
No hydrological issues are expected at this time. Looking at fair
weather with mainly clear skies for a couple more days as high
pressure moves over the region. Our next chances for showers
come Thursday afternoon and night with only light precipitation
expected.

Below normal temperatures today then they moderate with above
normal readings Thursday into the weekend. The diurnal melting
of the remaining snowpack will occur.

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.
