Quiet weather tonight and early Saturday will be replaced by another
active period Saturday night through Monday... With scattered showers
and storms expected. High pressure builds in Tuesday and Wednesday
with dry weather returning before the next shot of rain

Near term through Saturday night
400 pm update...

main concerns in the near term remain focused around the potential
for valley fog tonight and Saturday morning... And then the onset of
showers and storms from the SW Saturday afternoon... Tracking mainly
along and south of the ny pa border through Saturday night. There
may be a concern for strong to possibly severe storms and or heavy
rain Saturday night Sunday morning in NE pa, but the threat may end
up being well south of the wilkes-barre scranton area. Strong
winds, hail and heavy downpours are the main threats.

Weak high pressure in place tonight with light winds and mostly
clear skies will lead to another night morning of valley fog across
the SRN tier of ny and NE pa. Fog is expected to lift and mix out
around 8-9 am and we'll likely see a few peeks of Sun in the morning
before a more robust area of cloud cover moves in on the leading
edge of a warm front extending ewd from sfc low tracking across the
srn great lakes. The location of this front will be an important
factor in determining where the strong severe storms develop and the
potentially heavy rain falls. The warm front should slide ewd across
central pa early Sat afternoon with convection developing over much
of the WRN part of the state, lifting E newd through the rest of the
day into the evening. A strong thermal moisture gradient associated
with the front will set up and allow the most intense storms to
focus on. The dividing line between the humid unstable air mass and
the drier stable air will be sharp. Ml CAPE values will range from
50 to the north... To 2000 j kg to the south. Pwats to the north will
be around 1.3" north... And over 2" to the south. So, there is still
some uncertainty regarding the northward extent of the heavy
precip... But there has been a noticeable shift swd in confidence.

So... Pops QPF were lowered over much of central ny Sat afternoon-
night... And enhanced or maintained from the ny pa border south.

The area that we'll need to keep an eye on will be mainly NE pa
where the most unstable, moist air mass will be co-located with an
area of deep layer shear. The surface low to the west of the warm
front appears to be fairly progressive, and should kick the
convection to the east through the night with precip tapering off
after midnight and possibly ending early Sunday morning.

Temperatures tomorrow will only rise into the upper 70s and lower
80s in central ny... With mid to upper 80s over NE pa. Night time
lows will fall into the 60s.

Short term Sunday through Monday
For Sunday, all four main synoptic models (gfs, nam80, cmc and
euro) all show another in a series of waves moving east with
strong thermal and moisture advections for ny and pa. Model qpfs
vary as to the onset of the showers and storms. The 12z euro
suggests showers and storms make it to eastern ny by 00z Monday
with the other models holding the eastward progress back to the
finger lakes by 00z Monday. So for pops we went with chance (am)
to likely(pm) in our western forecast area to no pops(am) to
slight chance(pm) in our eastern forecast area. For Sunday
night, models all move the wave and associated showers and
storms through in the evening so have high pops. Models do show
instability creeping in within a sheared environment suggesting
potential for severe thunderstorms again. Additionally, the
current wet hydrological conditions suggest flash flood
potential. So we will continue mentioning these hazards in our

For Monday, upper level trough will be over ny and pa and we
continue unsettled weather pattern of scattered showers and

Long term Monday night through Friday
For Monday night and Tuesday, cold air advection and moisture
on the backside of this upper level trough will keep lingering
showers across our area Monday night which will fade on
Tuesday. After a brief period of dry weather Tuesday night and
Wednesday, next wave with warm and moisture advection brings
chances for more showers and storms Wednesday to Thursday with
lingering showers possible again on Friday.

Aviation 20z Friday through Wednesday
Vfr conditions expected the rest of today. Fog is likely to
form again later tonight, particularly at kelm but also likely
at kavp. Should see ifr vsbys through approximately 12-13z sat
morning.VFR conditions the rest of the morning.


Saturday through Monday... Periodic restrictions in
showers thunderstorms expected, especially Saturday night-

Tuesday and Wednesday...VFR.

Bgm watches warnings advisories
Pa... None.

Ny... None.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
