Synopsis
A cold front will arrive late tonight or early Saturday morning
and exit the region by Saturday afternoon. High pressure builds
in for Saturday night through early next week.

Near term until 6 am Saturday morning
Convection continues to shift off the coast... At least the nrn
portion. The SRN portion lags behind... And will be tracking
through mainly SE va well into the overnight hours.

Drying lowering of dew points will be very slow as main cold
front is sluggish to push across the area from the wnw. Keeping
highest pops across the ERN parts of the fa oavernight. Lows
from the l70s NW to m-u70s elsewhere.

Short term 6 am Saturday morning through Monday
The models are still struggling on how much push is there to
get the front through the region on Saturday. With a strong
shortwave trough digging through the ohio valley, it makes sense
that the front will temporarily stall waiting for the shortwave
trough to move past. This should allow the front to finally get
south of the area and off the coast by Saturday evening. So
have kept a low chance for showers and afternoon storms over ne
nc and the tidewater area on Saturday.

High pressure builds into the area on Saturday night into Sunday
and lingers through Monday. Temperatures will be a couple
degrees cooler, but the humidity will be much less making for
more comfortable conditions.

For temperatures, highs on Saturday will still be in the upper
80s to the lower 90s and that will continue on Sunday and
Monday. But overnight lows Saturday night and Sunday night will
be cooler with readings in the upper 60s NW to low to mid 70s
se.

Long term Monday night through Friday
Sfc high pressure builds north of the area with stacked high
pressure residing off the southeast coast through Mon night. A
thermal trough develops in the lee of the appalachians for
tue Tue night, and then a cold front is expected to track
through the area on wed... Exiting the coast Thu morning.

Conditions will become increasingly more humid ahead of the
front. Thunderstorm activity expected to become widely scattered
tue as convection develops INVOF lee trough. The frontal passage
wed Wed night will provide a better focus for more organized
thunderstorms to occur. Lingering showers storms possible far
se va NE nc on thu. Otherwise, cool canadian high pressure
builds across the midwest with dry conditions anticipated for
the mid atlantic region Thu night-fri night.

Highs tue-wed generally upper 80s to lower 90s; low-mid 80s
beaches. Highs Thu Fri low-mid 80s; mid-upper 70s beaches.

Lows mon-tue nights generally 70-75f. Lows Wed night
mid-upper 60s NW to 70-75f se. Lows Thu Fri nights around
60f NW to around 70f se.

Aviation 02z Saturday through Wednesday
Nearly solid line of tstms now moving through central va-se md
and will continue E through 02-04z 19 W possible gusty winds
and lower vrb cigs-vsbys (mainly at ric sby). Did hold onto
vcsh vcts INVOF the rest of the sites through about 04-06z 19 as
convection is slow to wane overnight. MainlyVFR conditions sat
though possible isold tstms in the afternoon SE va-ne nc invof
lingering weakening frontal boundary.VFR Sat night-mon as high
pressure builds back into the region. Some early morning fog
possible both Sunday and Monday mornings.

Marine
A cold front approaches the region through this evening with
isolated to scattered thunderstorms developing along a weak
boundary along the mid atlantic coast. Winds generally south
10-15kt the rest of today with locally higher gusts of 20-30kt
possible in thunderstorms. The front crosses the waters late
tonight with more widespread and organized thunderstorms
anticipated. Strong wind gusts above 30kt, heavy rainfall, and
frequent lightning will be the primary impacts. Seas 2-3ft build
to 3-4ft this evening and during the frontal passage later
tonight... Subsiding closer to daybreak Sat morning. Waves will
average 1-3ft through tonight. Synoptic SCA conditions still not
anticipated tonight except with the thunderstorms associated
with the front. If any headlines are necessary, they can be
handled with short- fused mws or smw products.

Winds light and variable AOB 10kt by mid-morning Sat through sun
as the front stalls near the mid atlantic coast. Winds become
more onshore Sun night into Mon as the front sags well south of
the area. Seas subsiding from 2-3ft Sat aftn to 2ft by late sat
night through most of Tuesday. South winds Tue tue night as a
thermal trough develops inland with seas building to 2-3ft
tue 3-4ft Tue night. Winds SW around 15kt bay ocean
tue night Wed as the next cold front is expected to cross the
region. Seas waves average 2-3ft. Winds n-ne AOB 15kt behind
front Thu fri. Seas 2-3ft waves 1-2ft.

Tides coastal flooding
Minor coastal flooding is expected for areas adjacent to ches
bay INVOF bishops head late this evening. Water levels should
reach 3.5ft around high tide, which occurs at 1136 pm this
evening. Cambridge is expected to reach 3.1ft, thus remaining
below minor flooding thresholds.

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.
