138 pm edt Sun may 20 2018

A cold front will cross the region this afternoon with
isolated to scattered showers especially from the capital district
south and east. A drier air mass will build in tonight with a return
to spring time temperatures for the start of the school and work
week. The surface high slides off the northeast coastline Monday
night as the next weather system approaches for Tuesday with the
threat for additional showers.

Near term until 6 pm this evening
As of 135 pm edt... A sfc cold front continues to push south and
east of the capital region, southern vt and the northern
catskills this hour. A sfc dewpt boundary or secondary cold
front is dropping south and east from the mohawk valley, lake
george region, and southern vt. Some isolated to scattered
continue across the region, especially south of the adirondacks,
and lake george. Sfc dewpts reached the mid and upper 60s from
aly south and east, and the latest rap SPC mesoanalysis depicts
sbcapes of 500-1000 j kg south of albany. We placed a slight
chance of thunderstorms for ulster, dutchess and litchfield
counties this afternoon. Limited heating and organization should
mitigate any severe threat, but gusty winds to 30-40 mph will
be possible with any storms. The 3-km namnest and hrrr both
shows some isolated cells in the southeast extreme of the
forecast area.

Temps are spiking up in the hudson valley due to downsloping. We
increased MAX temps to the lower 80s near kpou, and increased to
the mid and upper 70s near the capital region. The goes-16
visible satellite imagery shows breaks occurring in the cold
advection north and west of the capital region, the best chance
of sunshine this pm will be from the berkshires capital region
north and west with refreshing W to NW winds of 10-20 mph with
some gusts to around 25-30 mph. Highs will be in the 60s to
lower 70s in most other spots, except some mid and upper 70s
near the ct river valley in southeast vt, and the southern
reaches of litchfield co.

Short term 6 pm this evening through Tuesday night
Tonight... In the wake of the frontal passage, combination of
clearing skies from northwest to southeast as high pressure
building in from the central great lakes and diminishing winds
should allow for a cool overnight. A few upper 30s are possible
in the southern dacks in the cold advection regime with mainly
40s elsewhere.

Monday... A nice start to the work and school week as high
pressure remains in place across the region. So we will remain
with a dry forecast under plenty of may sunshine. This should
allow for temperatures to rebound back into the 70s for many
locations to perhaps near 80f for portions of the mid-hudson
valley. Upstream we closely monitor deeper convection that is
forecast to develop and track east-northeast.

Monday night... Upstream convection is expected as convective
debris will increase cloud coverage for most of the region
during the night. As for precipitation chances, seems the
deeper moisture profiles will occur from here and points
southward. Temperatures fall back mainly into the 50s.

Tuesday... Fast moving short wave and weak warm advection from
the ohio valley will allow for the potential of showers to
return back to the forecast area throughout the day. At this
time, the best potential for showers will be across the southern
2 3rds of the region. QPF values appear rather light with
minimal instability per surface based parcels and elevated

Tuesday night... First cold front is forecast to move across the
region. This should also take most of the moisture content hence
falling pops during the overnight period under partly cloudy

Long term Wednesday through Saturday
An upper level shortwave trough will be sliding eastward across
quebec and into northern new england for Wednesday into Wednesday
night. As this occurs, a surface cold front will be crossing the
region from west to east, although this front will be fairly
moisture starved. Cannot totally rule out a brief shower (mainly
for northern areas) on Wednesday, otherwise, it will be dry with a
mix of Sun and clouds and winds switching to the northwest. Temps
should reach the mid 70s for most on Wednesday and fall into the 50s
for Wednesday night, with some 40s across the higher elevations.

With a northwest flow in place both at the surface and aloft, it
will be continued dry for Thursday, and temps will be a few degrees
cooler, with highs in the upper 60s to mid 70s. Dry weather should
continue into Friday as surface high pressure remains near the area
with temps a few degrees warmer.

By the weekend, upper level heights will be starting to rise and the
low level flow will be out of the south. Temps should continue to
be above normal. It will probably be mainly dry for Saturday,
although low-level moisture will be increasing thanks to the
southerly flow. Any upper level forcing for showers looks to remain
to the west across the great lakes for Saturday, although this could
be closer to the area by Sunday. There remains some uncertainty to
coverage of showers and thunderstorms, as tropical moisture over the
gulf of mexico and western atlantic ocean could eventually come into
play, although this is still very uncertain and unknown at this
time, as this will depend on the track and development of any
tropical or subtropical lows well south of the area. For now, will
just go with slight to low chc pops for Saturday, and chance to
likely for Sunday, with valley temps mainly in the upper 70s.

Aviation 18z Sunday through Friday
With plenty of lingering low level moisture in place, flying
conditions are currently ifr lifr for all TAF sites thanks to
low ceilings of under 1000 ft. Although winds had been calm or
light for much of the night, southerly winds are increasing to
around 10 kts. Over the next few hours, ceilings should start to
improve, initially to MVFR by the mid morning hours and
eventually toVFR by the late morning or early afternoon hours.

As a cold front moves through the area, there could be some
spotty light rain showers or sprinkles but coverage will be too
few to warrant more than just a vcsh at this time.

By afternoon, winds will switch to the NW behind the cold front
andVFR conditions will be in place for all sites with no more
threat for any showers as drier air starts to work into the area.

Winds may gusts up to 20 kts this afternoon, mainly for
kalb kpsf, through the early evening hours.

Clear skies are expected tonight with light or calm winds for
all sites. With lingering low level moisture in place, some
radiational fog may be possible late at night, mainly for
kpsf kgfl.


Monday: no operational impact. No sig wx.

Monday night: low operational impact. Slight chance of shra.

Tuesday: moderate operational impact. Chance of shra.

Tuesday night: moderate operational impact. Chance of shra.

Wednesday: low operational impact. Slight chance of shra.

Wednesday night: no operational impact. No sig wx.

Thursday: no operational impact. No sig wx.

Fire weather
A cold front will bring a renewed threat of scattered showers
this morning into the afternoon, as a drier air mass will
follow tonight into Monday.

Minimum rh today will average between 50-70 percent. Those
values recover tonight with values at or above 80 percent.

The winds will be gusty west to northwest winds today in the
wake of the cold front will occur at 10-20 mph with gusts around
30 mph at times. The winds will diminish tonight with high
pressure building in.

No widespread hydrological impacts are expected the next 5 days
ending Wednesday.

Total rainfall amounts are expected to be between 0.75 inches
and 1.50 inch through today. Some rises are expected on rivers,
but no flooding is anticipated.

A drier air mass builds later this afternoon through Monday
with the next of chance of rain arriving on Tuesday.

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.
