Synopsis
Dry and seasonable weather is on tap for today as
high pressure builds over the region. A few showers may be possible
tonight as a warm front moves through the area. Warmer and more
humid weather returns on Friday ahead of a strong cold front.

Showers and thunderstorms will be possible late Friday into Friday
night as the front passes through the forecast area. Some of these
storms could become strong to severe, with damaging wind gusts.

Near term until 6 pm this evening
Surface high pressure continues to build into the region this
morning as a strong upper ridge holds steady across the southeast
conus. Due to the ridging in place, low level moisture remains
trapped beneath the inversion, resulting in mostly overcast
skies this morning. This has helped prevent radiational fog
development overnight but has also kept temperatures steady in
the 50s. Today, we can expect mostly cloudy skies across most
locations, except for maybe some partial clearing in the mid-
hudson valley, with highs in the upper 60s to low 70s.

Short term 6 pm this evening through Friday night
A warm front will approach and pass east across the region late
tonight. A few light showers may be possible with some
overrunning of moisture and forcing along the front, so have
maintained slight chance pops.

Friday will be warmer and more humid behind the warm frontal
passage, with breezy south to southeasterly winds. These winds
will aid temperatures warm back above normal, with highs in the
mid to upper 70s. At this point, Friday looks mostly dry with
the cold front and any upper level forcing well to the west. So
have kept most locations dry until late in the day when the cold
front approaches from the west. This front will cross our area
Friday night, and have trended the passage even slower than
previous forecast. Instability looks to be very limited,
partially as a result of the unfavorable overnight frontal
passage timing, however wind shear will be strong. Showers
associated with the front could contain some localized strong
gusty winds and maybe a rumble of thunder if any instability is
realized along the front. SPC currently has our area in a slight
risk for severe weather Friday Friday night and this would
likely be in association with any localized convective wind
gusts that could develop along the front. Any convection will be
low- topped but fast-moving, although it will likely be
weakening as it moves east into increasingly less unstable air.

At this time it appears that the best chance of rain and
thunderstorms will be Friday evening into the overnight period,
moving quickly from west to east.

Long term Saturday through Wednesday
In the wake of the frontal passage overnight, high pressure settles
back into the region from the mid-west and great lakes region for
the first half of the weekend. Dry, cooler and more seasonable
weather with ample sunshine Saturday. As h850 temperatures should
be in the single digits, this should equate with highs mainly in the
60s.

Cold front approaching the western great lakes region Saturday night
will dissipate as upstream surface ridge pinches off additional
moisture. So some cloud coverage increase to the north of i-90 into
Sunday but remaining dry. After overnight lows mainly in the 40s,
under partial sunshine Sunday should allow highs to return back
mainly into the 60s.

That weak nearly backdoor cold front settles across the region
Sunday night before return back as a warm front for early next week.

Meanwhile, moisture near the i70 corridor will begin to lift
northward overnight Monday. So clouds on the increase which leads
into a period of soggy weather Tuesday into Wednesday. Showers with
embedded thunderstorms will be possible during this time frame with
the higher concentrate of wet conditions expected Wednesday at this
time.

As an increasing southerly flow increases, temperatures and
humidity levels will continue to rise. Highs should climb into the
lower half of the 70s into the mid week period with increasing
dewpoints once again.

Aviation 08z Thursday through Monday
Latest goes-16 nighttime microphysics satellite imagery shows
low level clouds within MVFR category expanding across the
forecast area as moisture remains trapped below the nighttime
inversion. Light northerly winds and per the satellite imagery,
seems fog may be limited as we will remove from the tafs at this
time.

Ceilings will break up and clouds will become scattered while
rising above 3000 feet after about 13z this morning. Once the
clouds become scattered above 3000 feet, those conditions should
prevail through the afternoon. Winds then become south to
southeast at 6 kt or less during the daylight hours.

Thursday night: moderate operational impact. Chance of shra.

Friday: moderate operational impact. Breezy chance of shra... Tsra.

Friday night: high operational impact. Breezy likely shra... Tsra.

Saturday: no operational impact. No sig wx.

Fire weather
Dry and seasonable weather is on tap for today as
high pressure builds over the region. A few showers may be possible
tonight as a warm front moves through the area. Warmer and more
humid weather returns on Friday ahead of a strong cold front.

Showers and thunderstorms will be possible late Friday into Friday
night as the front passes through the forecast area. Some of these
storms could become strong to severe, with damaging wind gusts.

Rh values will decrease to 50 to 60 percent during the day
today, but then rebound to between 80 and 100 percent tonight.

Rh values dip back into the 60 to 80 percent range Friday
afternoon before rebounding to near 100 percent Friday night as
a cold front passes through the region.

Winds will shift to southeast at 5 to 15 mph today. Winds will
become breezy on Friday mainly from the south at 10 to 20 mph.

Hydrology
Dry weather is forecast today. The next chance of some rainfall
will be late tonight into Friday, as a warm front advances
northward across the region. Best chances look to be across the
northern half of the area.

A cold front will bring additional showers and perhaps some
thunderstorms Friday afternoon and night. Then drier weather is
expected to return for the upcoming weekend into early next
week.

including observed and forecast river stages and lake

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.
