Synopsis
High pressure over the region with result a pleasant dry day
with seasonal temperatures and light winds. A low pressure
system will move into the region Thursday resulting in humid
conditions with showers and thunderstorms likely during the late
afternoon into the evening.

Near term until 6 pm this evening
Ridging at the surface and aloft across the region will result
in a pleasant day with abundant sunshine, seasonable
temperatures and light winds. Expecting highs from the mid 60s
to lower 70s with some cooler readings above 2500 feet in the
western adirondacks and southern green mountains.

Short term 6 pm this evening through Friday night
Strong to severe thunderstorms possible late in the day Thursday
into the evening especially west of the hudson river.

The center of the surface high will shift off mid atlantic
coast tonight. The upper ridge axis is expected to crest over
the region this evening then begin to flatten overnight as a
low pressure system, which brought the severe weather to the
plains, moves into the great lakes region. This system will
impact our region Thursday and Thursday night as it approaches
and moves through. Initially some showers are possible late
tonight into Thursday morning as the warm front lifts into the
region. We will get in the warm sector and it will get humid as
dew points rise into the mid 50s to lower 60s during the
afternoon. Guidance has come into better agreement with the
timing of associated short wave riding over the top of the
ridge approaching the region during the afternoon tapping into
the peak heating of the day. Convection is expected ahead the
cold front as it sweeps through with likely pops 21z- 03z is the
forecast.

Guidance continues to indicate a highly sheared environment
with 0-6 km bulk shear values of 50 to 60 knots expected so
given sufficient instability supercells will be possible. The
guidance indicates that a tight instability gradient should
present across the local area with the greater instability to
the west of the hudson river dropping off quickly to the east.

Mucape values of 500 to 1000 j kg are possible west of the
hudson river during the late afternoon into the evening. Of
concern is the fact 0-3km storm relative helicity values of up
to around 400m2 s2 are modeled. Will continue to highlight
severe threat in our hazardous weather outlook.

With the passage of the low and cold front drier air will be
ushered back into the region with dew points dropping into the
mid 40s to mid 50s. The region will be under cyclonic flow
Friday which will result in partly sunny skies for most of the
day. There will be slight chances for showers mainly the morning
across the western southern adirondacks into the western mohawk
valley and across southern vermont into the northern berkshires.

Seasonably warm temperatures with highs from the upper 50s to
lower 70s. Ridging builds in for Friday night, however its
visit will be brief as another low pressure system approaches.

Long term Saturday through Tuesday
The period starts out on Saturday with surface high pressure
shifting south and east of the region, with an upper level ridge
axis directly over the region. However, by afternoon the upper ridge
also shifts east as the flow aloft becomes flatter. At the surface,
a warm front will be quickly approaching from the west. So chances
for showers will increase especially north and west of albany during
the first half of the day. Guidance in fairly good agreement with
the main synoptic features, with our area likely getting into a warm
sector by late in the day into Saturday evening. A pre-frontal
trough moving eastward across the region along with increasing deep
layer moisture will result in likely showers. There could be some
limited instability in the warm sector, so will mention a chance of
thunderstorms accompanying the showers Saturday afternoon evening.

The pre-frontal trough should be well east of the region by Sunday
morning. However, the system's cold front is then forecast to move
through during the day. Much of the deeper moisture is expected to
shift east of the area, so will only a mention slight chance of
showers associated with the cold front passage. Warming ahead of the
cold front with westerly flow should result in slightly above normal
temperatures. Dry conditions in store for Sunday night, as surface
high pressure builds in behind the cold front.

Monday (memorial day) looks to start out dry, however a fast-moving
short wave trough aloft and associated surface cold front is
forecast to move through during the afternoon. Again, there is good
model agreement with this system. There will not be much time for
any significant moisture return, so will only mention low chance of
showers at this time. Monday does not look like a rain-out, rather
just widely scattered showers. Temperatures should be close to
normal.

Dry and cool conditions then expected again Monday night in wake of
the cold front passage. Surface high pressure settles in over the
region on Tuesday, resulting in plenty of sunshine and slightly
below normal temperatures.

Aviation 12z Wednesday through Sunday
High pressure will remain in control through this evening,
before shifting southeastward off the coast overnight. This
will result inVFR conditions persisting through the 24 hour taf
period ending 12z Thursday. Just some sct high level cirrus
clouds will move in today, with mid level clouds increasing
ahead of an approaching warm front later this evening. Widely
scattered showers may affect the kpou kpsf terminals after 08z
Thursday.

Winds will be north-northwest around 5 kt, increasing to 5-10
later this morning. Winds will become light and variable
tonight.

Outlook...

Thursday night: high operational impact. Likely shra... Tsra.

Friday: low operational impact. Breezy no sig wx.

Friday night: no operational impact. No sig wx.

Saturday: moderate operational impact. Likely shra... Tsra.

Saturday night: high operational impact. Likely shra... Tsra.

Sunday: low operational impact. Slight chance of shra.

Sunday night: no operational impact. No sig wx.

Memorial day: moderate operational impact. Chance of shra.

Fire weather
Minimum relative humidity values in the 30s this afternoon...

high pressure over the region with result a pleasant dry day
with seasonal temperatures and light winds. A low pressure
system will move into the region Thursday resulting in humid
conditions with showers and thunderstorms likely during the late
afternoon into the evening.

Hydrology
A low pressure system will approach and move across the region
Thursday and Thursday night. Some showers are possible late
Wednesday night and Thursday morning as the warm front moves
into the region. Increasing chances for showers and thunderstorms
Thursday afternoon into the evening as the system's cold front
moves through. Generally 1 4 to 1 2 inch of rainfall is expected
with locally higher amounts due to brief downpours with the
thunderstorms. The rainfall is not expected to be hydrologically
significant. Another round of storms is expected Saturday
afternoon and evening as another low pressure system moves
across the region.

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.
