Synopsis
An upper level disturbance will move across ny and pa this
afternoon and evening bringing scattered showers and isolated
thunderstorms to our area. After this disturbance passes by,
high pressure will build into our region for Sunday and Monday
with fair weather and seasonable temperatures. The next chance
for precipitation will come Tuesday as a cold front approaches
the region.

Near term through Sunday
Scattered showers are developing across western ny and northwest
pennsylvania as weak capping indicated on the 12z buffalo
sounding begins to break down. Strongest storms are beginning to
develop over eastern ohio and these will track east-southeast
across western pa during the next few hours remaining well to
our south and west. Latest hrrr and rap forecasts continue to
indicate only margninal levels of instability in our area with
mlcape values maxing out near or just above 500 j kg and the
best chances for organized convection remaining to our south and
west. We are expecting scattered showers with isolated thunder
to move across our area during the mid afternoon through early
evening followed by clearing overnight, then patchy low clouds
and fog around daybreak Sunday. Sunday looks like a mostly
sunny and seasonably warm day with highs in the mid 70s to lower
80s as high pressure builds across the area.

Short term Sunday night through Monday night
During this period, zonal flow aloft combined with high
pressure moving from eastern pennsylvania to off the new jersey
coast will keep the area dry. High temperatures on Monday will
range in the middle to upper 80s.

Long term Tuesday through Friday
4 am update... Medium range models continue to show good
agreement through the extended period. No significant changes to
current forecast just minor adjustments based on latest
guidance. A cold front will pass through the area late Tuesday
night into Wednesday morning. A secondary trough a Thursday may
trigger isolated thunderstorms otherwise the rest of the period
looks dry and cool with high pressure from eastern canada
dropping into the great lakes region. Highs temperatures Thursday
through Saturday will range in the upper 60s to middle 70s.

1245 pm update... On the large-scale, model agreement is fairly
good this period, indicating a transition towards more
amplification once again next week. This pattern should take
the form of a western canadian-northwest CONUS trough, central
conus-intermountain west ridge, and an eastern canadian-
northeast CONUS trough.

The week should start out generally rain-free and warm from
Monday through much of Tuesday, with highs mostly in the 80s. As
heights aloft begin to fall ahead of the developing eastern
trough mentioned above, a cold front should slowly approach, and
bring increasing chances of showers thunderstorms from later
Tuesday into Wednesday.

Later next week, although we should trend drier behind the
aforementioned cold front, it likely turn much cooler as well.

In fact, by next Thursday Friday, we're looking at highs in the
upper 60s-lower 70s for many areas of cny nepa.

Aviation 18z Saturday through Thursday
Scattered showers with isolated thunder will develop across the
area this afternoon into this evening. A shower is possible at
any of the TAF sites between 19z and 01z today and have included
a tempo group at bgm elm avp for a showers where we believe the
best chance for a shower will be. After 01z skies will become
clear to partly cloudy with patches of low cloud and fog after
06z. Skies will become mostly sunny on Sunday with just
scattered cu. Winds will be west at 10 to 15 kts with a few
higher gusts this afternoon, northwest at less than 10 kts
tonight and west at around 10 kts on Sunday.

Outlook...

Sunday through Monday...VFR. Possible ifr in valley fog early.

Tuesday... Restrictions possible in thunderstorms.

Wednesday...VFR.

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.
