Marine Weather and Tides
Marlboro Meadows, 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.

Synopsis
A cold front will push south through the area today. High
pressure will build eastward from the great lakes tonight,
eventually moving offshore by Friday. Moisture will increase
ahead of a low pressure system over the weekend into early next
week.

Near term until 6 pm this evening
A cold front stretches across pennsylvania this morning.

Convection in northeast pennsylvania is moving to the east, and
the convective complex in west virginia is rapidly weakening,
with radar returns east of the appalachian crest dissipating.

Thus, am largely expecting the day to start dry. There could be
some patchy fog, but development will be hindered by convective
debris clouds.

Expect some clearing as the day progresses and the cold front
pushes south into the area. Moisture and forcing will be weak
along the front, although it will still be near our southern cwa
border as peak heating is reached. 00z href suggests showers and
thunderstorms will begin developing near or south of
charlottesville around midday, then quickly move southeast by
late afternoon. Have introduced 30-40 pops to this area, though
it's possible convective initiation occurs south of our cwa.

High temperatures will be in the lower to mid 80s for most
locations.

Short term 6 pm this evening through Friday night
The center of surface high pressure will be located over the
great lakes tonight, moving overhead by Thursday evening, then
off the mid-atlantic coast Friday. With ridging building aloft
as well, a respite from the recent unsettled weather will extend
through the end of the work week. Temperatures will be a little
above normal, with highs in the lower to mid 80s, and low
temperatures in the 50s to lower 60s.

Some moisture will begin to advance northward in the return
flow on the back side of the high by late Friday and Friday
night. Most of this advection will be focused on the ohio
valley, and while it's not impossible a few showers could
develop over the appalachians, have kept the forecast dry
through Friday night for now.

Long term Saturday through Tuesday
Southerly flow will continue advecting moist and
warm air over our region on Saturday as a bermuda high is settled
over the north atlantic. Temperatures will be between the low and
the mid 80s on Saturday with possible showers and thunderstorms in
the afternoon due to diurnal heating.

A low pressure system will be moving north from the gulf coast and
along the southeastern states Sunday into Monday as bermuda high
continues settled east of us. Winds will be turning more easterly as
moist air continues to be advected Sunday and Monday with
additional showers and thunderstorms.

A boundary will approach the area on Tuesday and settle over us into
Wednesday. This may trigger more showers and thunderstorms both
days.

Aviation 07z Wednesday through Sunday
A challenging aviation forecast to start the morning. Ifr
ceilings had developed over the baltimore and washington metro
areas and were forecast to remain in place through sunrise.

However, these clouds have dissipated as thicker mid level
clouds moved in. These clouds also seem to be thwarting any fog
development, although there may be some clearing right around
daybreak. Amendments to the tafs are likely through the period.

Otherwise a cold front will push south today, turning winds to
the northwest shortly after sunrise. It will be a dry frontal
passage for the most part, although a stray shower or storm
could develop near cho around 17-20z. High pressure will then
build across the area through Friday.VFR conditions and light
winds are expected through the period.

Vfr conditions likely Saturday with possible afternoon showers
and thunderstorms which may decrease the cigs. Sunday and Monday
looks wetter with additional moisture over us, therefore more
showers and thunderstorms possible.

Marine
A surge of southwest winds accompanying a disturbance has been
affecting the southern maryland waters. Given the hrrr had
picked up on this trend, issued a small craft advisory through 6
am. Winds seem to be on a downward trend now though, and the
advisory may be cancelled early.

A cold front will push south through the area this morning, with
winds becoming northwesterly. It looks like peak winds will be
around 15 kt through the day, with a low probability for a few
higher gusts. High pressure will build across the waters tonight
and Thursday before moving offshore on Friday with light winds.

Some of the wider waters of the bay may come close to sca
criteria Friday night as southerly flow increases on the back
side of the high.

Winds are expected to remain below SCA criteria from Saturday
into Monday, not anticipating an advisory for this period.

Tides coastal flooding
Tidal anomalies should decrease today as northwesterly winds
develop behind a cold front. However, water levels remain more
elevated around dc given some freshwater input, with the current
high tide barely coming in below flood stage. This situation
may repeat itself during the morning high tides the next couple
days.

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.
