What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Surface high pressure across the mid-atlantic tonight will move
offshore on Friday. Weak disturbances will cross the area over
the weekend into early next week, before a potential low
pressure system approaches later in the week.

Near term through Friday
Very dry air is in place over the area with pwats less than
half an inch which is around the 10th percentile for this time
of the year. Lows will be near normal tonight in the low 50s
under clear skies and light winds.

Previous afd...

quiet weather is expected through tonight. Surface high pressure
overhead will slide offshore by Friday morning. Mostly clear
skies and light winds are expected, with some patchy fog
possible in the favored valleys. Lows will be mainly in the 50s,
except 60s in the urban centers and along the chesapeake and
tidal potomac river.

Short term Friday night through Saturday night
Southerly return flow will develop on Friday as the surface high
moves into the western atlantic and upper level ridging builds
overhead. This will help to usher in increasing warmth and
moisture. Much of the area should still see mostly sunny skies
and dry weather, however across the higher terrain of the
potomac highlands, and possibly into the shenandoah valley late,
a few showers and isolated thunderstorms may develop in the
afternoon evening. Highs will reach the 80s area-wide.

Any showers thunderstorms should largely dissipate Friday night,
although a shower or two remains possible across the potomac
highlands into western maryland. Lows will be considerably
milder given increasing low level moisture, with lows in the 60s
to locally near 70f.

Moisture increases further on Saturday with persistent southwest
flow, and precipitable water values may exceed 1.75". Highs will
reach into the mid 80s, and that combined with dew points in the
mid upper 60s will lead to the development of moderate
instability. A weak disturbance is progged to be nearby the
region as well. Thus, showers and thunderstorms become
increasingly likely by the afternoon and evening. Shear values
are relatively low, so while organized severe activity is not
anticipated, a stronger storm or two is possible. In addition,
given very high precipitable water values, and wet antecedent
conditions, some isolated incidents of flooding are also
possible.

Shower thunderstorm activity should wane with the loss of
daytime heating Saturday night. A muggy night is forecast with
lows in the 60s to low 70s.

Long term Sunday through Thursday
On Sunday, high pressure will be situated off the eastern
seaboard near bermuda. A south to southwesterly flow will be in
place over the region. The southerly flow will lead to the
inflow of tropical moisture into the region. Models are showing
pwat values above 1.5", possibly reaching 2.0". A stationary
front is expected to be located somewhere to our north in pa and
new york. The influx of high precipitable water values along
with the boundary to the north will lead to the formation of
disorganized convection throughout the region. Thunderstorms and
heavy showers will be possible throughout the region. High
temperatures are expected to be in the upper 70s to mid 80s.

Monday into Tuesday, a southerly flow is expected to continue
leading to further transport of tropical moisture into the region
from the gulf of mexico. Pwat values may be slightly lower on
Monday and Tuesday, with the boundary to the north possibly
moving back southward as a backdoor front before a cold front
from the west moves through the our northern parts of our
county warning area. These boundaries will act as a convergence
zone and help provide the lift needed to allow convection to
kick off and lead to the chance for thunderstorms and heavy
showers. Temperatures look to trend upward through the early
parts of the week with temperatures peaking in the 80s to
possibly near 90f in some locations.

Wednesday, a high pressure system will be situated over the
northeastern us. A weak east to southeasterly flow will be in place
over our region. The flow off the bay coupled with existing pwat
values will lead to the ideal conditions for the formation for
further convective showers and thunderstorms.

Aviation 02z Friday through Tuesday
Vfr is expected through Friday night as high pressure builds
across the area. The chance for fog at any of the terminals
through the period looks slim, although mrb would stand the
highest chance. Winds will be generally less than 10 knots
through tonight. Southerly flow will then become established
Friday. A disturbance will likely bring scattered showers and
thunderstorms on Saturday.

On Sunday, a southerly flow will be in place with disorganized
showers and thunderstorms possible, along with potential for
sub-vfr conditions. The unsettled weather will continue into
Monday with showers and thunderstorms possible.

Marine
As high pressure moves offshore tonight into Friday, southerly
flow will develop, but should remain below SCA criteria. Some of
the wider waters of the bay may reach SCA criteria Friday night
as southerly flow increases, but confidence is low. Winds may
also be marginal on Saturday, although the larger threat may
come from thunderstorms during the afternoon and evening.

Showers and thunderstorms will be possible with storms creating
strong gusts both Sunday and Monday. The southerly flow over
the chesapeake may also lead to the need for a small craft
advisory on both Sunday and Monday.

Tides coastal flooding
Minor coastal flooding is possible at dc waterfront at high tide
fri morning (5:32 am fri). However, confidence is not very high
at this time and the most likely scenario is that it stays just
below flood stage.

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.
