Synopsis
A passing low pressure system will bring rain through the coming
day. Rain will gradually diminish to showers Wednesday night
into early Thursday. Other passing disturbances could produce
showers at times Friday into Saturday, followed by dry and
warming conditions early next week.

Near term through today
842 pm update...

the models continue to be too aggressive advecting
precipitation into a very dry airmass, indicated by dew points
in the 30s. We slowed the advance of the precipitation into our
counties early this evening by a few additional hours.

Precipitation should fill in as humidity rises in the lower
atmosphere late this evening.

The latest grid update has been sent.

Previous discussion...

mid and high clouds making some progress into the area this
afternoon well ahead of the rain and the center of the storm.

Clouds weren't fast enough to slow the temperatures making it
into the mid and upper 60s and lower 70s. At low levels still
dry with the rain across western ny and central pa. Rain is
making slow progress and will only get into the far west and
southwest early evening, then to most of the CWA by midnight.

The stacked low moving northeast out of the carolinas will
channel atlantic moisture northwest into the area ahead of it.

Steady rain will be over the area late tonight into Wednesday
then start to lift northeast. The rain will be slow to end as
the northern and southern streams try to phase over our area
late wed. Wed night the remaining wrap around rain showers lift
northeast into mostly cny by sunrise.

Rainfall amounts are similar with half an inch to an inch across
most of the area. 1 to 1.5 inches possible in the upslope
regions of the southern catskills to the poconos. The entire
area has now had several days of dry weather so this amount of
rain over a long period shouldn't be an issue. Thunderstorms
should stay along the coast. Over our area low and mid levels
will be saturated and stable.

Temperatures closer to normal with lows in the 40s both night
and highs Wednesday in the 50s.

Short term tonight through Friday
Upper low pulls east into western new england on Thursday.

Instability and cool air will result in scattered showers with
below normal temperatures. Brief ridging on Thursday night into
early Friday ahead of a fast moving low. Significant differences
exist in the models with the euro dry Friday while the NAM gfs
bring showers across the area as the low shears apart. With
continued upper trofiness, better chance that there will be a
few showers than none so have included chance pops during the
day Friday.

Long term Friday night through Tuesday
Long wave trof will be over the area for the weekend keeping
cool air and unsettled weather for the region. Best chance for
showers will be on Saturday as a short wave rotates through the
trof enhancing the instability. Drier air and some ridging
arrives for Sunday and Monday. Expect temperatures to return to
near of slightly below normal on Monday as the air mass modifies
and heights build aloft.

Aviation 06z Wednesday through Sunday
Low pressure system will bring gradually deteriorating
conditions today, as rain and lowering ceilings overspread the
terminals. Fuel alternate required ceilings will start impacting
kavp during the remainder of the night, and kbgm-kelm as well
prior to dawn. As the system works its way northward, kith-ksyr
and eventually krme will eventually get into fuel alternate
required ceilings. Moisture will become abundant enough to bring
all terminals to ifr ceilings later today into this evening; see
tafs for onset timing specifics as well as for rain and visibility
details. Wind for now will be east or southeast 5-8 knots,
including marginal low level wind shear at kavp, but will become
variable this afternoon and then generally northwesterly late
today-this evening as low pressure passes.

Outlook...

late Wednesday night into Thursday morning... Showers diminish yet
restrictive ceilings persist. High confidence for restrictions.

Thursday afternoon and Thursday night... MVFR ceilings scatter out
in afternoon;VFR into Thursday night. Moderate confidence.

Friday to Saturday night... Some restrictions possible from rain
showers at times. Moderate confidence.

Sunday...VFR. High confidence.

Bgm watches warnings advisories
Pa... None.

Ny... None.

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.
