Synopsis
Unseasonable late-september heat will continue in central pa
through mid week. Mostly dry weather will also prevail with
a passing shower possible in spots on Wednesday and Friday or
Saturday. A pattern change will bring cooler, fall-like weather
back to the area for second half of the week into the upcoming
weekend.

Near term until 6 am Tuesday morning
Another unseasonably warm and muggy late-september day in
progress with MAX temperatures fcst to reach the mid 80s to
low 90s or +15-20 degrees above normal. It will feel even
warmer with MAX hx values between 90 and 95 degrees; a few spots
may event get into the mid-upper 90s. Hard to deviate from
persistence in this pattern. Tonight will be another repeat:
very mild with mainly clear skies and more valley fog after
midnight lasting into early Tuesday morning.

Short term 6 am Tuesday morning through Tuesday night
Another day of summerlike heat and humidity expected across
central pa. Highs may be trimmed a bit across southeast pa as
some clouds bands associated with maria wrap into the area. Some
hires and even coarser global models try to develop some
isolated convection Tuesday afternoon but odds remain strongly
in favor of dry wx pattern.

Long term Wednesday through Monday
By wed, the start of the cooldown back to seasonal temperatures
will be underway. The blocking high that has been responsible
for the recent extended spell of dry and anomalously warm
conditions will flatten as a trough slides across southern
canada, dragging a weak cold front through on Wed and nudging
maria eastward. This front will bring our first chance of rain
in quite a while - though with the front weakening and falling
apart as it moves through any scattered showers will remain
light.

Maria (remaining offshore of the carolinas) will make it as far
north as the nc va line before it takes its hard turn eastward
and finally tracks away from the east coast.

A bit more significant trough will approach for late week into
the weekend, bringing a reinforcement of the cooler temperatures
and a renewed chance for light yet scattered showers as the
airmass remains quite dry.

Aviation 20z Monday through Saturday
WidespreadVFR conditions into tonight. No reason to deviate
from persistence with fog restrictions likely again after
midnight into early Tuesday morning.

Tue... Am valley fog becomingVFR.

Wed... Spotty pm shower possible. MainlyVFR.

Thu... No sig wx expected.

Fri-sat... Isold-sct showers possible. MainlyVFR.

It is not checked for accuracy either by anyone at L-36.com 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.
