Synopsis
High pressure will slowly weaken its grip over the
area Tuesday and Wednesday as hurricane maria moves northward
through the western atlantic. A cold front will move through
Thursday, bringing more seasonable temperatures for the end of
the week. Little if any rain is expected.

Near term until 6 am Tuesday morning
Weakening ridge of high pressure remains overhead tonight as
hurricane maria slowly moves northward offshore of north
carolina. This will promote light easterly flow in the low
levels overnight and into Tuesday morning. Currently looking at
a scattered-broken deck of high clouds across the region that
will persist through the night, but also monitoring low stratus
that has developed near the atlantic coast and will likely make
a westward push overnight in the light easterly flow. This
stratus may overspread the metro areas and points east by
Tuesday morning. In addition, patchy fog is also possible in the
favored areas late tonight into early Tuesday morning. Lows will
be mild, in the 60s to around 70f.

Short term 6 am Tuesday morning through Wednesday night
Clouds associated with hurricane maria will spread
northwestward early Tue morning and as far west as the blue
ridge mountains. There could be a few showers in southern md,
otherwise thickening clouds.

Long term Thursday through Monday
Conditions will be dry for Thursday into Friday with cold front
to our east and high pressure building from the west over our
area. In the meantime, hurricane maria will be moving away from
the us east coast.

An upper trough could bring some showers over our area late Friday
into Saturday, but dry conditions return for the rest of the long
term period with high pressure building in over our region. High
temperatures will be near normal around 70s or 80s... Colder at
higher elevations.

Aviation 00z Tuesday through Saturday
Vfr will continue under scattered to broken high clouds through
around midnight tonight. Afterward, ifr conditions are possible
in low stratus beginning first at mtn, and then moving westward
to bwi dca iad by Tuesday morning. In addition, patchy fog and
reduced visibilities are possible, with greatest likelihood of
ifr visibilities at mrb cho. Conditions will gradually improve
Tuesday morning withVFR area-wide again by Tuesday afternoon.

Additional low stratus and fog is also possible Tuesday night
into Wednesday morning.

Vfr conditions expected Thursday into Saturday. Some
showers possible Friday night.

Marine
Winds will strengthen tonight through Wednesday as
pressure gradient tightens in response to approaching hurricane
maria. SCA is in effect for Tuesday and Tuesday night. A cold
front will move through the area early Thu with gales possible.

Winds will diminish Thu night
small craft advisory expected Thursday into Friday for some
zones of our waters. Lighter wind gusts expected for Saturday.

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.
