Synopsis
Strong high pressure will build north of the region through
early next week. A tropical cyclone could form over the weekend
and move near the southeast coast and out to sea. A cold front
will cross the region on Wednesday.

Near term through Sunday
Patches of cloud cover are likely tonight in onshore flow around
high pressure situated to our north. Where and when conditions
clear, patchy fog will likely develop. Below normal temperatures
in the 50s and 60s are expected.

Short term Sunday night through Monday night
Ridge of high pressure will remain in control along the eastern
seaboard on Sunday with northeasterly flow continuing. A mix of
sun and clouds is anticipated again with fair weather cumulus
developing through the day. Once again an isolated shower or two
is possible, mainly near the bay. Highs will be similar to
today, in the 70s to near 80f. Lows Sunday night in the 50s 60s.

Surface high pressure will be positioned near coastal maine by
Monday with an area of low pressure southeast of the carolinas.

This will help to turn low level flow more easterly, which will
promote more of a marine influence. That in combination with
an upper trough moving towards the area from the mississippi
valley may act to bring more cloud cover in addition to the
possibility of some isolated to scattered showers. Highs Monday
will likely remain in the 70s. Lows Monday night in the 60s.

Long term Tuesday through Saturday
High pressure will start to weaken and shift off to our
northeast on Tuesday. A cold front will slowly approach our
region from the west. The models have this cold front moving
through our region some time on Wednesday Wednesday evening. A
coastal low tropical system will move northward offshore of
the atlantic coast. The system should remain well off-shore with
little sensible impact to the region aside from promoting mostly
easterly flow Tuesday into Wednesday. The easterly flow will
lead to increasing moisture in our region with temperatures
both Tuesday and Wednesday in the mid 80s. Showers and
thunderstorms could be possible as the frontal boundary moves
through our area Wednesday afternoon and evening.

The cold front is expected to be fully through our our region
by Thursday morning. High pressure will build back into our
region from the west through Friday. Daytime temperatures will
average in the mid 80s with dew points in the 50s.

Aviation 01z Sunday through Thursday
Patchy fog possible especially near mrb cho later tonight.

WidespreadVFR will return on Sunday. Winds will be generally
northeasterly through Sunday.

Vfr is likely Monday as well, although easterly flow may promote
thicker cloud cover and some isolated to scattered showers. MVFR
conditions are therefore possible at some locations Monday and
Monday night.

An increasingly easterly flow will lead to broken to overcast
skies Tuesday and Wednesday. Some clouds bases could reach
sub-vfr condtions especially as a cold front approaches on
Wednesday.

Marine
Sca is in effect for the lower tidal potomac and central
chesapeake bay this evening, overnight, and through Sunday.

Additional small craft advisories may be needed for the marine
zones Sunday night and Monday as a pressure gradient is
maintained between the high pressure to the north and northeast
and the developing coastal low pressure system near the
southeast u.S.

Winds will be mostly out of the east Tuesday through Wednesday.

Marginal winds near SCA criteria will be possible.

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.
