An upper level trough will remain to our west through mid week.

Weather disturbances moving out of the trough will cross the
overnight into Wednesday. A larger area of low pressure may
approach late Thursday.

Near term through today
Update 12:15 am have adjusted wind, dew point, and temperature
based on latest observations. No other changes.

Previous discussion...

radar showed activity filling in as the upper S WV lifts up
across the region as seen on the latest satl WV imagery. 18z
surface analysis showed area of mid to upper 50 dewpoint air
nosing up into the eastern side of the CWA while lower 50
dewpoints hold back to the west. Expecting the column to moisten
more as shown by the latest rap and nam. Jet streak of 30-35 kt
noted at 925 mbs to lift N into the evening to provide lift.

Llvls have warmed enough thanks to sunshine returning.

Atmosphere will destabilize more into the evening allow to tstms
to fire. Cold temps aloft(-20c at 500 mbs) will allow for the
potential for hail and inverted type sounding will lead to some
strong wind gusts. Associated cold front is expected to lift
across the region later in the evening into the overnight
period. Hail potential still a threat but things appear to shift
to strong winds gusts as noted by the latest hrrr and very
heavy rainfall. Storms moving over areas that have been hit
earlier could lead to some localized flooding. Added patchy fog
w the sse flow expected overnight and moist blyr.

The cold front continues to slide across the area on Wednesday
w more action setting up for the day. There looks like there
could be a reprieve in rainfall through mid morning. Another
round of shower activity expected later by the afternoon. Steep
lapse rates around 6.5 c km and CAPE of 400-700 joules will
allow for the threat for tstm. This activity will be fueled by
the upper level trough swinging across the region. Once again,
the risk for some hail and gusty winds is there but at this
point, confidence is low and decided to leave out enhanced
wording for now. Daytime temps will be somewhat similar to today
w upper 60s to lower 70s. As pointed out by the midnight crew,
well below normal for late june.

Short term tonight through Friday
The upper trof will exit through the canadian maritime
provinces early Wednesday evening followed by partly to mostly
cloudy skies. Lows will drop back to the low 50s north and mid
to upper 50s downeast. The next in a series of upper impulses
will cross the region Thursday with a more showers and chance
for thunderstorms mainly across the north. Unsettled weather
continues Thursday night and as a warm front lifts north of the
region. Expect mainly cloudy skies with the chance for showers
and thunderstorms. Friday will continue unsettled with more
showers and thunderstorms expected as a cold front crosses the
region from the northwest. High temperatures both Thursday and
Friday are expected to be near normal in the low to mid 70s,
except cooler along the coast.

Long term Friday night through Tuesday
The cold front will stall out across central portions of the
region Friday night and then begin to move back north as a warm
front Saturday and Saturday night. This will continue the
unsettled weather pattern with the chance for showers and
thunderstorms. Showers and thunderstorm chances continue on
Sunday as a cold front moves across the region. It finally looks
like a drier weather pattern may finally be in the offing next
week as a large ridge of high pressure builds toward the region.

High temperatures will be close to normal through the period.

Aviation 04z Wednesday through Sunday
Near term: mostlyVFR this evening, but with brief ifr in
heavier showers and thunderstorms. Conditions across the region
will likely lower to ifr late tonight W lower CIGS and vsby due
to some fog. Improvement to MVFR and evenVFR early Wednesday
and then a drop back to MVFR and perhaps ifr by afternoon W the
showers and possible tstms.

Short term: the main story with regard to aviation weather will
be the potential for showers and thunderstorms Friday right
through Sunday. Overall most of the time will remainVFR
outside of possible MVFR or even lower conditions in any times
of showers and thunderstorms.

Near term: no headlines anticipated through the period. Some
elevated convection expected overnight W some fog to limit vsbys
at times. Winds expected to remain around 10 kts W seas around 3

Short term: a small craft advisory may be needed mainly for
seas Friday into the upcoming weekend.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. 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.
