115 pm edt Sat may 27 2017

A milder start to this holiday weekend under variable cloud
coverage and mainly dry conditions. The next chance for wet
weather arrives Sunday night into Monday as a warm front lifts
northward across the region.

Near term until 6 pm this evening
As of 1 pm, main forecast challenge continues to be cloud cover.

Much of the hudson valley has become partly to mostly sunny,
while diurnal clouds have blossomed across portions of the
catskills adirondacks. Meanwhile, an area of mid clouds
associated with a remnant MCV is approaching from central ny.

Have continued with mostly cloudy skies over the
catskills adirondacks while trending from partly to mostly
cloudy with time this afternoon for areas from the capital
district south associated with the mid clouds. Remainder of the
forecast is unchanged.

Previous discussion... There is some weak ridging over the
region at the surface with a ridge axis located to our west
aloft. A short wave which over overtop the ridge will approach
late in the day. Skies are variable cloudy across region with
multiple cloud layers. Made adjustments to cloud cover and
temperatures based on observational data. The hrrr continue to
indicate isolated terrain based showers may develop as we do
remain within a rather moist cyclonic flow regime. Also the
upstream short wave will add some additional lift across the
northern most portion of the forecast area. Kept slight chance
pops on the forecast just pushed off start time until later in
the afternoon. Near seasonable high temperature today in the 60s
to lower 70s; much warmer than last couple of days for most of
the forecast area.

Short term 6 pm this evening through 6 pm Sunday
The fast moving short wave tracks across northeast ny, then
through vt and nh this evening as we will hold onto the slight
chance pops for these areas through the evening hours. The
remainder of the overnight period, increasing subsidence as
short wave ridge axis slides across the entire region toward 12z
Sunday. As surface high transverses the region with moist ground
under partly cloudy skies at least, this will potentially bring
the possibility of fog as we will place this in the grids for
several locations overnight. Overnight lows will range from
45-55f across the cwa.

Any sunshine we receive during Sunday will become increasingly
filtered through the day as the short wave ridge slides east of
the region with the approach of the warm front and convection
developing along and ahead of this boundary. This may be the
warmest day of the holiday weekend with mainly dry conditions
and temperatures able to climb back into the 70s for valley
locations and 60s elsewhere. Marine influence air mass may
advect northward across the mid-hudson valley, eastern
catskills into NW ct through the day too as southerly low level
flow increases ahead of the approaching upstream warm front.

Long term Sunday night through Friday
An unsettled pattern looks to continue to be in place through much
of the extended period.

At the start of the period, a large closed off upper level low will
be moving from the northern plains and canadian prairies towards the
western great lakes for Sunday night into Monday. Ahead of this
feature, weak shortwave ridging will be departing off the eastern
seaboard with south to southwest flow in the low to mid levels
across our area. With increasing moisture advection and warm air
advection in place, a period of steadier rain showers looks to occur
for late Sunday night into much of the day on Monday. Steady precip
will be tapering off during the afternoon hours on Monday from west
to east, as the best moisture lift shifts into eastern new england.

With the clouds and precip, temps will be on the cool side. Lows on
Sunday night will be in the upper 40s to mid 50s ahead of the
approaching precipitation and will only reach into the 60s for

The upper level low will be slowly shifting eastward across the
great lakes region and ontario on Tuesday into Wednesday. Ahead of
this feature, broad southwest flow will be in place. With 850 hpa
temps warming to around 10 degrees c, temps will be warmer on
Tuesday with highs well into the 70s. However, it will continue to
be fairly cloudy, with a partly to mostly cloudy sky. Another
approaching frontal boundary will allow for some additional
scattered showers and possibly a thunderstorm, especially during the
peak heating of the day. As the upper level low starts to get
closer, falling heights and temps aloft will allow for temps to be a
few degrees cooler on Wednesday, with valleys only reaching the
lower to middle 70s. However, there will continue to be a few more
showers around (especially for northern areas closer to the upper
level forcing) thanks to the moist cyclonic flow in place and still
plenty of clouds throughout the day.

By Thursday into Friday, the upper level low will be weakening and
shifting into quebec. Still cannot rule out a few passing light
rain showers (mainly for northern areas) due to the continued
cyclonic flow, but coverage looks to be much less than earlier in
the week and there looks to be more breaks of sunshine compared to
earlier in the week as well. Highs will generally be in the low 70s
for valley areas, with 60s across the hills and mountains.

Aviation 17z Saturday through Wednesday
Ceilings will vary from MVFR ifr toVFR before becoming
predominantlyVFR today. Ceilings at kpou may beVFR all day.

Ceilings will then rise into theVFR range after 13z-14z at all
taf sites.

Kpsf will linger the longest with MVFR CIGS until the late
morning early afternoon.

The winds will be generally light from the north to northwest
at 6 kt or less this morning. Light and variable direction
winds of 5 kts or less are likely late Saturday morning into the
early afternoon.


Sunday night: moderate operational impact. Likely shra.

Memorial day: high operational impact. Likely shra... Tsra.

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

Tuesday: moderate operational impact. Likely shra.

Tuesday night: moderate operational impact. Chance of shra.

Wednesday: moderate operational impact. Chance of shra.

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

Thursday: moderate operational impact. Chance of shra.

Fire weather
Slightly warmer and drier Saturday with light northwesterly
winds. A bit warmer still on Sunday with light southerly winds.

Rh values will bottom out in the 50s both days. Showers and a
few thunderstorms become likely Sunday night into memorial day.

Mainly dry weather is expected this weekend. An approaching
system will bring the likelihood of showers and a few
thunderstorms Sunday night into memorial day, with total qpf
ranging from 0.25-0.75" expected. Additional periods of showers
and thunderstorms are likely Tuesday and Wednesday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
