A warm front will approach from the south today as a cold front
approaches from the west. The cold front will pass through later
tonight and early Monday morning. Low pressure stalled over
northern ontario during mid-week will create a slightly cooler
than normal and unsettled stretch of weather.

Near term until 8 am this morning
Fog and some low stratus have already formed in the SW and
clouds cover the NE mtns now, as well. The flow at cloud level
will be more from the E SE through the night and clouds will
expand a bit more through the night under weak high pressure and
it's subsidence inversion. A few patches of drizzle are possible
if the fog stratus can get a few kft thick.

Short term 8 am this morning through 6 pm Monday
The mean sfc-850 mb flow becomes more southerly during the
daytime. This should help bring more-mild air in, but the
mountains tend to thwart good mixing and make it difficult to
really get temps cranking. However, there will be some breaks
start to for in the morning. Some of the higher terrain may then
be ripe to pop a few showers. The column is not all that
unstable at first, but the chance for storms increases during
the afternoon. Again, they will be popping off the higher
terrain elevated heating surfaces at first, then expand some.

Initial storm motions may be slow, and they may kill themselves
off before they get too tall. CAPE will be limited due to the
limited heating sunshine in lots of places. The destabilization
will be easiest in the east where less low clouds are expected,
but the deeper moisture is off to the west and the dynamics are
even farther to the west. Pwat GOES above 1.5 inches in the
west by the end of the day Sunday. Will ramp pops up in the west
through the aftn, leaving the east in chc or less pops. Have
made a slight tweak earlier in time for some showers storms
over the laurels and alleghenies. Temps will get into the m70s
for the eastern valley cities, but only near 70 elsewhere.

Widespread showers and storms will occur this evening and
through the night. The NAM is trending quicker with the cfropa
and others are following suit. The SREF is also aggressive with
the fropa. Even if the slower models come to fruition, the
front will be to the susq river by 12z and little if any showers
are expected after 15z in the east. It should turn out to be a
really nice day with just a westerly breeze. Temps may be a bit
higher than currently advertised due to some earlier clearing
and the downslope effect.

Long term Monday night through Saturday
Dry conditions expected Tuesday morning before significant
cooling aloft accompanies a pair of short waves late Tuesday and
later Wednesday.

Pops during this midweek period will be painted as chc -
translating to scattered showers with preference for the
majority of the QPF (albeit quite light at that)to be across the
typical west-nwrly flow upslope prone areas of the laurel
highlands and NW mtns. The chance for any thunder will be very
minimal Tuesday through Thursday.

Generally dry NW flow occurs late in the week into next weekend as
a 1020 sfc high over the upper midwest Friday evening builds SE twd
the region. Pops thur night through Fri night will be 30 percent or

After our bout of coolish weather with temps several deg f below
normal Sunday and Monday, GEFS mean temps rebound back to near or
slightly above normal (even under slightly cooling 850 mb temps)
for Tuesday through at least Thursday. Ecens mean temps are several
deg warmer than the GEFS and nat'l blend of models temps. Leaned
closer to the cooler solutions based on the few-svrl deg c of
cooling aloft with near to slightly below 850 mb temps.

Aviation 07z Sunday through Thursday
Fog developing in earnest across much of the region at 07z. Ifr
to lifr conditions exist across much of the region, but there
are some notable exceptions, such as kbfd and kipt where
conditions are stillVFR. While expecting fog development at
kbfd soon given no t TD depression, fog may hold off at kipt as
t TD still showing 4 degrees of spread. Model guidance actually
supports limited fog at kipt. Did include some MVFR restrictions
at kipt at this issuance.

Early low clouds fog will begin to lift after 12z, withVFR conditions
expected in most locations by afternoon. However, there is at least
some potential of a moist sse flow into the mountains creating a
MVFR stratus deck along the east slopes of the appalachians from
bfd south through unv,aoo and jst. The other area of concern will
be isold tsra impacts across the western airfields associated
with a warm front pushing into the region.

Mon... Am showers low CIGS possible.

Tue... No sig wx expected.

Wed... Slight chance of showers reduced cigs.

Thu... No sig wx expected.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
