What's New / NOTES
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.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Synopsis
High pressure will bring dry weather and slowly moderating
temperatures through the weekend. After a cold night tonight,
highs will reach the 50s in many areas on Saturday, with 40s at
higher elevations. Temperatures will reach the 60s in the hudson
valley by Monday.

Near term until 6 am this morning
As of 130 am edt, latest goes-16 IR imagery shows some cloud
cover across the adirondacks, lake george saratoga region, and
southern vermont. This cloud cover is gradually reducing in
coverage so have trended the sky cover in this direction through
the morning hours. Also did a quick adjustment to the hourly
temps to reflect recent obs where values are already falling
into the 20s to mid 30s. Sent updates to ndfd and web servers.

Prev disc... As of 930 pm edt, skies have become mostly clear
across large portions of the mohawk and hudson valleys into the
eastern catskills, with clouds more prevalent across higher
elevations of southern vt, the berkshires, and into the
taconics litchfield hills. Latest rap13 hrrr data suggest valley
areas remain mostly clear through the remainder of the night,
other than occasional patchy clouds. For higher terrain areas of
western new england, clouds may persist across southern vt
several more hours, while clearing out to the south across
berkshires litchfield hills. Some clouds will likely persist as
well across the far western adirondacks.

With the clearing trend continuing overnight, temperatures
should fall off into the 20s for most areas, given a possible
period of decent radiational cooling, with dewpoints already in
the mid 20s, decreasing winds, and an cold air mass remaining in
place.

Short term 6 am this morning through 6 pm Sunday
Quiet weather will prevail this weekend as high pressure builds
across the area. Temperatures will still be below normal for
late april but with improvement as highs Saturday will reach the
50s in the hudson valley and mid to upper 40s over higher
terrain. A few fair weather cumulus clouds will form Saturday
afternoon otherwise mainly sunny conditions will prevail.

Saturday night will be mostly clear and chilly with most areas
falling below freezing, and well down into the 20s in normally
colder locations north of the capital district. Temperatures
will recover into the 50s on Sunday, with a few spots in the
mid-hudson valley possibly touching 60, along with ample
sunshine and light winds.

Long term Sunday night through Friday
Upper ridging with associated dry and tranquil weather expected
Sunday night through Tuesday. Temperatures will gradually warm
as well. Highs Monday in the mid 50s to lower 60s. Highs Tuesday
in the upper 50s to mid 60s.

Some high clouds may spread across the region Tuesday afternoon well
in advance of the upper system beginning to approach from the
central u.S. The leading edge of deeper moisture, isentropic lift
and stronger boundary layer jet energy and warm advection is
expected Tuesday night into Wednesday. There are considerable
differences in sources of guidance ensembles in timing and track of
strong upper energy and associated upper dynamics and low level
forcing. However, there is a good consensus in guidance ensembles on
unsettled weather Wednesday through Friday.

The strongest upper energy and low level forcing may track south of
our region, as well as some semblance of a warm sector. So, with
the prospect of the warm sector tracking south of our region and
most of our precipitation associated with isentropic lift north of
the warm sector, indicating chances for rain and rain likely
Wednesday and Wednesday night.

Then due to uncertainties in the timing of the departure of the
system, solid chances for showers Thursday, then scattered showers
decreasing to isolated coverage through Friday. However, there could
be another strong upper closed low beginning to approach Friday from
the oh valley and great lakes. So, again, keeping at least isolated
to scattered showers with the uncertainties on timing.

With the clouds, rain and unsettled weather, highs Wednesday in the
50s with around 50 northern areas. Highs Thursday in the 50s but
near 60 southern areas. Highs Friday in the upper 50s to mid 60s
but some lower to mid 50s northern areas.

Aviation 06z Saturday through Wednesday
An upper level trough will gradually shift east of the region
today into tonight. High pressure will continue to build in from
the great lakes region today.

Vfr conditions are expected the next 24 hours for
kgfl kpsf kalb kpou. Some mid-level clouds are lingering this
morning from kalb north and east. These clouds should thin over
the next 3-5 hours. The strong subsidence associated with the
ridge building in will yield partly to mostly sunny conditions
with a few-sct cirrus and a few-sct stratocumulus. These clouds
will diminish by sunset.

West northwest winds will become light to calm this morning.

They will increase to 6-12 kt during the late morning into the
afternoon with a few gusts around 20 kt near kalb, and become
calm tonight.

Outlook...

Saturday to Tuesday: no operational impact. No sig wx.

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

Wednesday: moderate operational impact. Likely shra.

Fire weather
Scattered rain and snow showers will decrease in areal
coverage today. Temperatures will still be below normal through
today... But a pattern change will take place as high pressure begins
to build into the region and persist right through early next week.

Expect dry weather Saturday through next Tuesday with at or above
normal temperatures by early next week.

Relative humidity values will drop to 35 to 75 percent this
afternoon, recover to
75 to 100 percent tonight, and drop to 35
to 65 percent on Saturday afternoon.

Winds will be northwest at 5 to 15 mph today, except 10 to 20
mph across the higher terrain with gusts up to 40 mph, winds
will decrease in most areas tonight to around 5 mph with
northwest winds 5 to 10 mph in most areas on Saturday.

Hydrology
Rivers and streams are currently slowly receding from heavier
rainfall earlier this week.

Widely scattered to scattered rain and snow showers are expected
today with liquid equivalents less than a tenth of an inch. This
will have little to no impact on the main stem rivers.

Dry weather is expected Saturday through Tuesday with a
moderating trend in temperatures which will allow for some
snowmelt in the mountains. The next chance for widespread
precipitation mainly in the form of rain will be next Wednesday.

observed and forecast river stages and lake elevations, please
