Marine Weather and Tides
Vienna, MD

Version 3.4
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.

A cold front will drop south of the area this morning. High
pressure will build from the great lakes Monday, toward the
southern new england coast Tuesday, and offshore by Wednesday.

Meanwhile, low pressure tracks across the carolinas Monday night
into Tuesday, and then off the outer banks by Wednesday.

Near term until 6 am this morning
As of 1015 pm edt Sunday...

convection slowly waning this evening across NE nc counties.

Scattered to numerous covective cells developed late this
afternoon into the evening from central va into maryland
counties... Which then pushed SE toward the hampton
roads tidewater region this evening. Despite weakening lapse
rates, just enough wind aloft for several strong to severe
storms this evening. Have adjusted pops to ramp down a bit
faster overnight as cool front drops across the area and
drier air arrives from the nw, along with decreasing clouds.

Some more patchy fog toward morning over the piedmont. Still
warm tonight with lows ranging from the upper 60s NW to the mid
70s se.

Short term 6 am this morning through Wednesday
As of 400 pm edt Sunday...

24 12z ECMWF nam cmc have taken a more pessimistic turn from
Monday night through Wednesday for SRN va NE nc, while the
24 12z GFS still brings drier air trough the region Monday night
into Tuesday. High pressure is progged to build from the great
lakes Monday toward the SRN new england coast Tuesday, then
offshore Wednesday. Meanwhile, and upper low is progged to
trundle across the carolinas Monday night and Tuesday and off
the outer banks Wednesday. This could result is some bands of
showers and embedded tstms in low-level easterly flow. 20-30%
pops have been introduced for the far SRN tier of the area along
with increased cloud cover. Farther n, drier and partly cloudy
to mostly clear conditions are expected to prevail. Highs Monday
through Wednesday will mainly be in the 80s, with lows
primarily in the 60s, with low 70s across the se.

Long term Wednesday night through Sunday
As of 400 pm edt Sunday...

an approaching mid and upper-level trough with an attendant
shortwave will result in a chance for showers and thunderstorms
Thursday morning through the early afternoon. Showers may linger
across the south into Friday morning, but there is enough model
disagreement on this that chance pops could be removed in later

High pressure builds in later on Friday and through the remainder of
the weekend, per the 12z global models, keeping much of the area
rain-free. However, would like to see better run-to-run consistency
before completely pulling slight chance pops out of the forecast.

Considering that it is summertime and dew points are expected to be
in the 70s with southerly flow, would hesitate to completely rule
out an isolated shower storm across the area fri, sat, and sun

Expect high temperatures in the low to mid 90s thu-sun with lows in
the low to mid 70s. Glancing at the beginning of july, GFS and euro
ensembles both suggest that warmer temperatures will sign up for an
extended stay over the mid-atlantic and northeastern u.S.

Aviation 07z Monday through Friday
As of 215 am edt Monday...

showers and tstms were moving off the NE nc coast early this
morning, withVFR conditions prevailing at the TAF sites. A cold
front will push south of the region this morning, with winds
becoming northerly and starting to usher a drier airmass into
the cwa.

High pressure will build fm the great lakes region ese to off
the SRN new england coast tonight into Tue night, as a wave of
low pressure moves acrs the carolinas to the coast. Still
expectingVFR conditions at the TAF sites today into tue
morning, but with more clouds coming back into ric and ecg
tonight into Tue morning. A sml chc or slgt chc of showers will
move back into ecg, orf, and possibly phf later Tue morning into
tue night, due to the wave of low pressure. Low pressure
lingers off the outer banks into wed, as another area of low
pressure moves into the great lakes. A weak front crosses the
area thu.

As of 230 am edt Monday...

a cold front moves south of the waters this morning then stalls
across nc later today. Winds shift into the N today, NE tonite, then
e on Tue as high pressure tracks north of the region. No flags in
the short term as wind remain below 20 kt into Tue due to the lack
of any significant advection. Seas 2-4 ft, waves 1-2 ft.

Models then diverge on how strong the ese fetch becomes late tue
into Wed as the pressure gradient tightens ahead of low pressure
that develops on the bndry across the carolinas. Wna suggests seas
build to arnd 5 ft across the SRN coastal waters along with sse
winds 15-20 kts. Given a low confidence forecast, bumped up wind
speeds and seas a bit, but kept them at or just below minimal sca
levels for now. Later shifts can raise SCA headlines as needed.

Continued a flood warning for the mattaponi river at bowling
green based off the latest gauge readings.

Allowed flood warning along the north anna NW of doswell to
drop, but did continue from doswell southeast to include the
upper pamunkey river near hanover. Ongoing flooding is due to
the combination of the heavy rainfall and increased dam releases
at lake anna. The increased dam releases have been terminated,
but it will still take some time for the water to flow through
the basin.

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.
