Synopsis
A cold front will cross the area on Tuesday. High
pressure then builds over the area Tuesday night through Friday
morning then shifts offshore this weekend as another frontal
system approaches from the west.

Near term through Tuesday
Low pressure (both at the surface and aloft) will track into
the great lakes tonight and the cold front associated with the
low will pass through the ohio valley. A southerly flow ahead of
the boundary will strengthen overnight... And this will allow
for more mild conditions along with deeper moisture from the
gulf of mexico. A strengthening low-level jet ahead of the cold
front along with the deep moisture will cause showers to
increase in coverage... Especially after midnight.

Models are showing strong forcing (200-meter 12 hr height
falls) over the area with pwats rising to around to 1.5 inches
or 250 to 400% of normal. In addition, wind fields will also
strengthen with models showing 850 mb and 500 mb winds of 50kt
and 80 kt respectively. With the substantial increase in winds
and moisture, there will be potential for t-storms Tue morning
through midday (12z-18z time frame). Stability indices and the
shrb (high shear low CAPE parameter) suggest potential for
severe t-storms given up to 500 j kg of CAPE and strong wind
fields just above the surface with a line of showers
accompanying sfc cdfnt. Biggest threat for severe t-storms is
east of the u.S. Route 15 corridor. Cdfnt will push east of the
ches bay by 18z with showers ending, but over the appalachians
the showers will continue and turn into snow showers.

A downsloping flow and increasing sunshine may offset cold
advection for a period Tuesday afternoon. Temps in the 50s and
60s are most likely.

Short term Tuesday night through Wednesday night
Turning colder Tue night under CAA pattern. Snow showers will
continue over the mtns with a few inches of accumulation
possible. A northwest flow ahead of approaching high pressure
will allow for dry conditions east of the allegheny highlands
along with seasonably chilly temps.

Long term Thursday through Monday
Dry conditions with near normal temperatures are expected for
Thursday and Friday as high pressure moves south or near our
area. Flow will change from northerly to southerly as the high
pressure moves offshore on Friday. Warm air advection will allow
temperatures to become above normal, especially for Saturday -
maybe Sunday- with some areas reaching the 50s.

Guidance suggests that a cold front will move through sometime late
Saturday or Sunday. Timing of the frontal passage and amount of qpf
is still uncertain but trending more into a Sunday event. Showers
associated to this could begin Saturday night. Behind the front, dry
conditions and cooler temperatures expected, with temperatures
dropping to near normal.

Aviation 01z Tuesday through Saturday
Developing ifr conditions mainly 06z-15z Tue with showers with
a slight chance of tsra. Llws also a possibility 06-15z. Cdfnt
pushes east of terminals after 15z with winds shifting and
showers ending.

Vfr conditions expected between Thursday and Saturday with high
pressure moving south or near our area.

Marine
Winds will strengthen tonight into Tue morning with
sca conditions. Showers or t-storms Tue morning may be capable
of producing brief strong convective gusts in excess of 33 kt
which may require smws. SCA conditions will likely persist
through wed.

Wind gusts could reach small craft advisory criteria on
Thursday before decreasing into Friday. Breezy conditions return
on Saturday with the cold front.

Tides coastal flooding
A southerly wind will strengthen tonight into Saturday morning.

Tidal anomalies will increase... But astronomical norms are low
due to the lunar phase. Therefore... Minor flooding is not
expected but it will be close for sensitive areas Tuesday
morning. An offshore flow will develop Tuesday afternoon behind
a cold front.

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.
