Marine Weather and Tides
Benedict, 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 is crossing our region tonight. High pressure will
build over us Monday into Tuesday. A low pressure system moving
across the great lakes will bring a warm front Wednesday
followed by a cold front Thursday. High pressure will build
behind the front by the end of the week and into the weekend.

Near term through Monday
Last showers are passing southeast and will likely clear the
region by midnight. With loss of insolation, no further severe
weather is expected, but brief heavy downpours are still
possible. As the front clears the region overnight, dew points
should drop, but some patchy fog could still develop in
sheltered locales. Otherwise, it likely turns out mostly clear
late with lows mostly in the 60s.

Short term Monday night through Tuesday night
Canadian high pressure will build from the north on Monday
allowing for northwesterly flow and lower dew points over our
area. High temperatures will be in the low to mid 80s on Monday,
and low 80s on Tuesday, meanwhile high temperatures will reach
the 70s at higher elevations.

High pressure will remain in control on Tuesday and will be
centered off of the new england coast on Tuesday. Flow will
become easterly to southeasterly. Upper level energy may enhance
some showers but guidance is suggesting it will be more in the
overnight hours.

Long term Wednesday through Sunday
A weakening surface low will be moving along the us canada border
throughout the day on Wednesday. At the same time, a surface high
pressure will be shifting off the east coast. Southerly flow will
push the warm front associated with the aforementioned low through
through the region on Wednesday morning. This, along with the
formation of a lee surface trough, should result in scattered
showers and thunderstorms in the afternoon, with the best chances
occurring in northern md and northern va. Given 30-40 kt flow at the
mid levels, some storms could be accompanied by gusty winds.

However, given the residual cloud cover from the warm frontal
passage in the morning, the amount of instability available will be
in question by the afternoon. With the southerly flow out ahead of
the cold front, temperatures will begin to increase, with max
temperatures into the mid 80s.

The surface low departs to the northeast early on Thursday, which
will drag a cold front through the region. This will bring another
chance for some pop up showers and storms Thursday afternoon,
especially given MAX temperatures in the low to mid 90s and dew
points in the low 70s. Forcing seems to be relatively weak with the
frontal passage, but enough instability should exist for at least
some scattered development.

A strong upper level ridge looks to move into the area on Friday
through the weekend, bringing dry conditions back to the region.

High temperatures will be very warm, with MAX temperatures expected
to be in the mid 90s.

Aviation 02z Monday through Friday
Last showers pushing southeast with no further severe weather
expected. Brief reduction possible at dca momentarily, otherwise
generallyVFR rest of tonight. Cold front crossing the region
should lower dew points later tonight, but some lingering
moisture and winds diminishing late could allow patchy fog
nevertheless. A high pressure will build over us on Monday and
remain in control through Tuesday allowing for mainlyVFR
condtions.

SubVFR ceilings are possible on Wednesday morning with the passage
of a warm front. Later in the afternoon, scattered thunderstorms
should develop across the region, bringing another chance for some
sub-vfr conditions. Thursday will be very similar, as a weak cold
front moves through the region.

Marine
Lingering showers may produce a brief gust to 25 knots rest of
this evening, but otherwise winds should generally stay below 18
knots next few days. Gradient is a bit elevated on Monday behidn
the front so we may be very close to sca, however, so will need
to keep an eye on it. The pressure gradient will weaken Monday
night into Tuesday as high pressure builds over the area,
therefore not anticipating any small craft advisory during this
time.

Sca criteria winds will be possible on Wednesday, given a strong
gradient across the region, and southerly flow. Scattered showers
and thunderstorms on Wednesday and isolated showers and storms
Thursday afternoon could result in additional gusty winds on the
waters.

Tides coastal flooding
Anomalies should continue to decrease on westerly to northwesterly
flow through Tuesday. Minor flooding is still possible through
Monday morning on the upper tidal potomac shoreline due to some
added freshwater input, but overall the tidal flood threat should be
very low.

Onshore flow will cause anomalies to increase again during the
middle of the week in tandem with a full moon (Thursday), resulting
in a renewed potential of more widespread (minor) tidal
flooding.

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.
