Synopsis
High pressure drifting southeast from the great lakes region
will bring cooler and dry weather for today. The holiday
weekend will feature warmer temperatures, higher 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 through tonight
Ridge of sfc high pressure extending SE into the region is
providing a clear start to the day with refreshingly lower
humidity reflected in sfc dewpoints residing in the mid to upper
40s across much of the cwa, and falling through the 50s in the
far SE zones.

A veil of high cloud remnants (varying in areal coverage and
thickness) from the current MCS over the upper miss valley will
spill ese into pa this afternoon and could dim the Sun at times,
especially across the NW half of the state.

Nw winds will gust into the upper teens and 20s later this
morning through this afternoon and high temps will range from
the mid 60s across the higher terrain of northern pa, to the
upper 70s in the SE metro areas.

Variable amounts of altocu and cirrus clouds will spread over
the region tonight. Min temps will be similar or a few deg f
cooler tonight than those of early today (Friday).

Short term Saturday through Saturday night
Saturday will star off quite tranquil with light wind,
comfortable temps and dewpoints along with variable amounts of
multiple cloud layers.

Deep-layer shear and warm advection will increase quickly late
sat morning and Sat afternoon as the sfc high pressure area 1025
mb) drifts SE off the nj coast. This will set the stage for a
few rounds of showers and sct strong to potentially severe tsra
as sfc based CAPE climbs above 1500 j kg across much of the
western half of pa by 21z. 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 maintained its slgt risk for svr tsra across the nw
third to half of the state, while the rest of our fcst area lies
within a mrgl risk for svr.

0-1km shear of 15-25 kts near the i-99 and route 219 corridors
will combine with the moderately high CAPE to yield ehis in the
2-3.5 m2 s2 range within these corridors. Any line segments or
more cellular tsra that moves within this more favorable
convective environment (at the eastern edge of the higher cape)
could display rotation and a higher propensity to rotate as
supercells or develops transient mini-bow echoes capable of
producing highly localized g50kt + and a few instances of large
hail.

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 Sunday through Thursday
The cold front sags southward into our area on Sunday, keeping
a chance of showers and storms across the area into Sunday
evening.

Most if not all of memorial day looks to be dry.

Most of Tuesday looks to be dry, perhaps a shower or storm
across the north.

Wednesday and Thursday looks to be harder to time, as a deep
polar vortex starts to phase with the next cold front. Thus have
some chance of showers and storms in the fcst.

This activity could linger into late Thursday night, given a
complex system.

Maybe a risk of frost at some point after fropa, but that is
further out than our fcst extends at this point.

Have a good holiday weekend.

Aviation 12z Friday through Tuesday
Building high pressure will provideVFR conditions today under
partly to mostly sunny skies, and a breezy northwest wind could
gust 15-20 mph.

Humidity creeps back in this weekend with showers and
thunderstorms again possible Saturday afternoon into Saturday
evening.

Outlook
Sat... Restrictions possible near scattered tstms, mainly north.

Sun... Restrictions possible near scattered tstms, mainly west.

Mon-tues... 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.
