Synopsis
The holiday weekend will feature warmer temperatures, increasing
humidity and a renewed chance for showers and thunderstorms,
mainly during the afternoon and evening hours Saturday and
Sunday. Memorial day itself looks to offer up fantastic weather
for much of the day with near normal temperatures and
comfortably lower humidity.

Near term until 6 am Saturday morning
Mid to high cloud remnants of midwestern convection will continue
stream into central pa over the upper ridge axis located well
to our west over the central ohio valley. Min temps will be
similar or a few deg cooler tonight than those of early today.

Majority of guidance shows all but the northwest remaining dry,
with just low chance pops required for the w.

Short term 6 am Saturday morning through 6 pm Saturday
Saturday will star off quite tranquil with light wind,
comfortable temps and dewpoints along with variably cloudy
skies.

Deep-layer shear and warm advection will increase quickly late
sat morning and Sat afternoon as the high drifts off the nj
coast. An approaching warm front will set the stage for a few
rounds of showers and isolated strong thunderstorms. Models pump
capes into the 1500-2000j range while developing respectable
helicity as the warm front progresses through the CWA in the
afternoon and evening. The eastern half of pa (and our eastern
cwa) will see much lower sfc-based instability which should
limit the svr weather threat.

Spc has its slgt risk across the NW third to half of the state,
while the rest of our fcst area lies within a mrgl risk for
svr.

Temps Saturday afternoon will rebound into the mid and upper
70s throughout many portions of central pa, but could hold in
the upper 60s to low 70s across the region near and east of the
susq mainstem where SE flow and thicker low clouds should be
found.

Long term Saturday night through Friday
315 pm update... In the big picture, a long-wave trough is
progged to stay in place along the west coast through the middle
of next week, with a flat upper ridge axis over the central and
eastern conus. In general, this means near to above normal
temperatures for central pa, with rounds of
showers thunderstorms about every 36-48 hours, courtesy of fast
moving short-waves and frontal boundary passages.

As for the daily sensible weather, warm frontal convection is
still expected Saturday evening, perhaps locally severe. On
Sunday, it will be warm and muggy, with a trailing cold front
bringing hit and miss, mainly afternoon showers and
thunderstorms. Memorial day looks quite nice from this early
vantage point, with rain-free weather, and comfortable
temperatures humidity levels. The approach of another warm
front, followed by trailing cold front Tuesday-Wednesday could
well lead to more showers and thunderstorms.

As mentioned above, temperatures will be on the warm side, with
daily highs mostly in the mid 70s-mid 80s range, and night-time
lows in the 50s and 60s.

Aviation 02z Saturday through Wednesday
Building high pressure will provideVFR conditions into Saturday
under partly cloudy. It will be breezy today out of the
northwest at 15-20kt. The wind will diminish to 10kt or less
overnight.

Humidity will return this weekend with showers and
thunderstorms again possible Saturday afternoon into Saturday
evening. Expect locally reduced conditions in the vicinity of
the convection, mainly in the afternoon into the overnight.

Outlook
Sat-sun... Restrictions possible near scattered thunderstorms.

Mon-vfr.

Tues-wed... GenerallyVFR, although a spotty showers or storm is
possible.

Ctp watches warnings advisories
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.
