It will remain very warm and humid today with scattered showers
and isolated thunderstorms over the northwestern half of the
state this morning. A pair of cold fronts will push southeast
through the state, the first arriving late today and tonight,
and the second Thursday afternoon and evening. Cooler and much
less humid air will move in for Friday and will last through
much of the upcoming weekend.
Near term through tonight
Plume of high pwat air (1.5-2.0 inches) over the central
appalachians will provide the fuel for numerous showers across
the NW half of the CWA through much of this morning, followed by
showers and scattered strong to svr tsra this afternoon as a
compact upper trough (moving east from lake michigan attm) and
nose of a 60kt, 300 mb jet to its south adds moderately strong
meso-b lift across the state this afternoon and evening.
Fairly linear vertical shear favors multi-cell tsra clusters
(with some mini bows echoes) that will form in one or two waves
across the central mtns this afternoon, and push gradually east
during the afternoon and early evening hours.
Localized very heavy rain of over one inch in just a 30 minute
period will occur where several showers and thunderstorms train
over the same locations, mainly SE of a kaoo to kunv and kelm
Forecast high temps (ranging from the low 80s in the north to
l90s in the middle and lower susq valley) may need to be trimmed
by 1-2 deg f in many some locations based of the rather
extensive showers and mid clouds across the northwest half of
the state this morning.
After the most potent tsra gradually diminishes and moves SE of
the region this evening, the CWA will be sandwiched between a
pair of cold fronts with the potential for some clearing and
and formation of valley fog (mainly in the deeper, northern pa
valleys containing the larger streams, creeks and rivers).
Short term Thursday through Friday night
A secondary sfc cfront and cfa dropping SE from the glakes
Thursday should trigger a few afternoon showers tsra across
the region. Er range mainly the SE half of pa. 700 mb temps
will likely cool off by at least 2-3c during the day Thursday.
Trailing upper trough, the mdtly strong uvvel within the
thermally direct re region of an upper level jet MAX will be
riding over the secondary frontal boundary that will slow down
or stall out temporarily somewhere across central or southern pa
as the flow aloft backs Thursday into Friday.|
Depending on the exact location of the quasi-stnry front and
area of enhanced lift beneath the re region of the upper jetlet,
there could even be a few periods of steady light, to briefly
moderate rain across central or northern pa and some elevated
tsra cores. Rainfall amounts later Thursday afternoon into
Friday should total a few to several tenths of an inch.
Conditions should improve from west to east late Friday, and
into the upcoming weekend.
Long term Saturday through Tuesday
An extensive area of high pressure will bring fair and dry
weather to central pa this weekend. Heading into next week, the
question will be how quickly can return flow moisture make it
back into the area? GFS is rather bullish early next week in
contrast to the ECMWF which favors continuation of dry wx. These
models seem to agree that developing southeast low level flow
may advect clouds into the area which could result in lower
highs mon-tue. Given the uncertainty, the day 4-8 ndfd forecast
closely follows the national blend of models (nbm) which shows
a gradual increase in low chance pops mon-tue.
Temperatures over the weekend will be near to slightly below
average with pleasant and warm afternoons and comfortably cool
nights. Another brief hint of autumnlike air with september
right around the corner. As mentioned above, could see temps
trend a bit lower early next week before moderating through
Aviation 10z Wednesday through Sunday
Coverage of showers across the western airspace should trend
lower as they drift eastward through the morning before ramping
back up again this afternoon evening. Cloud cover should limit
fog formation this morning but some lower ceilings are possible
especially across the western airfields. A cold front will push
slowly northwest to southeast across the airspace late tonight
through Thursday with high pressure building in by Friday.
Thu... Pm thunderstorms southern 1 2.
Fri... Chance of showers southern 1 4.
Sat-sun... Am fog possible.

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.
