Synopsis
An upper level disturbance will cross the region this afternoon
and evening. A cold front will approach the ohio valley
Wednesday, sinking into our area Wednesday night into Thursday,
possibly stalling into Friday. Behind the front, high pressure
will build over the region for the weekend.

Near term through tonight
A warm front is depicted across pennsylvania early this morning
as an area of low pressure is situated over the great lakes.

Over our area, skies are party to mostly cloudy as cloud debris
from decaying showers storms to our west and east drift
overhead. Temperatures are a touch cooler than we've seen the
past few nights, ranging from the middle 60s to lower 70s.

Dewpoints once again are on a similar track, so patchy fog is
being observed in the sheltered valleys along and west of the
blue ridge mountains.

The aforementioned low will track north and east of the great
lakes today, lifting the warm front into new england while at
the same time dragging a cold front toward the ohio valley late
in the day. As the upper level trough nearing west virginia this
morning slides eastward today, this will help trigger scattered
showers and thunderstorms this afternoon and evening.

Instability will not be as impressive as what we saw on Tuesday,
given a bit more cloud cover and slightly cooler temperatures,
and the best synoptic lift will reside north and east of the
mason dixon line. That being said, 1000-1500 j kg of mucape
should develop by this afternoon, along with modest low level
lapse rates and 0-6km shear coming in around 20-25 knots. Pwats
will remain elevated, hovering around two inches today. These
ingredients will support at least an isolated threat for severe
thunderstorms today, with damaging winds and large hail
continuing to be the primary threats.

Shower and thunderstorm activity this evening will dwindle, with
partly cloudy skies and mainly dry conditions persisting
overnight. Patchy fog will be possible towards morning as
temperatures bottom out in the middle 60s to middle 70s.

Short term Thursday through Friday night
The cold front will slowly drift into our area Thursday
morning, helping spark scattered showers and thunderstorms
during the afternoon and evening hours once again. Given the
front will be gracing us with its presence, while coinciding
with shortwave energy tracking overhead, do expect better
coverage of showers storms compared to today. Again, instability
may be limited given cloud cover and lower temperatures,
however we will remain moist and the flow will be parallel to
the front. So in addition to isolated strong to severe storms,
heavy rain resulting in isolated incidents of flooding will be a
concern.

The front shifts southward Thursday night into Friday, but
likely lingers close enough nearby to bring additional
scattered showers and storms on Friday afternoon and evening,
favoring our southern zones. Temperatures noticeably cooler on
Friday, likely holding in the 80s area wide. A drying trend
should commence Friday night as the front sinks further south
into southern virginia.

Long term Saturday through Tuesday
High pressure will build into the region from the north Saturday
and Sunday. Temperatures will be about 5 to 7 degrees below
average. Dry conditions and lower humidity is expected through the
period.

The high will move to the northeast Monday and Tuesday. This will
allow for a return southeast to southerly flow to bring the
humidity levels up and a chance of showers or a thunderstorms. The
discrepancy remains between the european models and GFS models as to
how many and how far north will showers and thunderstorms develop.

The european model keeps most, if not all, of our CWA dry through
Tuesday. The GFS model brings an upper level disturbance across our
region late Monday into Tuesday; thus, the chance for showers and
thunderstorms could be higher and farther north. Temperatures will
remain a few degrees below average, but humidity levels will rise
some.

Aviation 08z Wednesday through Sunday
Afternoon evening showers and storms can be expected through
Friday as a cold front slowly transits the area, bringing
periods of subVFR conditions. Patchy fog could also yield
MVFR ifr vis, mostly likely at mrb cho.

Vfr conditions for all terminals Saturday and Sunday. We can't
rule out a shower or thunderstorm near cho late Sunday into
Sunday night, which could briefly reduce conditions to MVFR.

Winds northeast around 5 knots Saturday and Saturday night. Winds
becoming easterly 5 to 10 knots Sunday.

Marine
Sca conditions expected over the waters today as the gradient
increases and a cold front nears the ohio valley. The gradient
is expected to relax overnight and remain below SCA criteria
Thursday and Friday. The front will drift over the waters on
Thursday, lingering nearby into Friday. As such, afternoon and
evening showers storms can be expected, some of which will
deliver strong gusty winds.

No marine hazards expected Saturday and Sunday. Winds northeast
around 5 knots Saturday and Saturday night. Winds becoming easterly
around 10 knots Sunday into Sunday evening.

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.
