Synopsis A broad and slow moving low pressure system over
the southeast will influence the mid atlantic through the
middle of the week. A pair of cold fronts will move through the
area during the second half of the week.
Near term through tonight
Digging upper low across the southeast and westward expansion of
the subtropical ridge will allow for deep moisture plume
sitting offshore to retrograde today and establish itself over
our area particularly along the i-95 corridor and areas that saw
a lot of rain Saturday. This spells a lot of trouble considering
the strong unidirectional flow that will be conducive to
training repeated convection over saturated ground and high
stream levels. Will be expanding and issuing a new flash flood
watch to cover most areas east of i-81. Statement will be issued
around by 5am. Shear also strengthens today which should result
in more organized convection and a threat of severe wx and even
brief isold tornadoes. We've seen some weak rotation with some
of the cells early this morning in northeast md.
Short term Tuesday through Wednesday night
Things get worse on Tue as moisture plume moves a bit more
inland and aims at washington dc. Model signal is stronger for
heavy rainfall with showers t-storms falling over saturated
soils. Coordination with neighboring wfos was not to issue the
flood watch for multiple days, but obviously the riks of flash
flooding will be extremely high. Wpc day ero has moderate risk
for almost the entire area.
Deep moisture plume will start shifting a bit more east on wed
with flooding threat diminishing somewhat for western areas but
remaining very high for eastern areas wed. Mid-level drying will
start taking place late Wed night with convection and risk of
flooding likely decreasing substantially after midnight wed
Long term Thursday through Sunday
By Thursday, the stubborn upper level trough that will influence our
weather much of this week should finally shear out and lift
northeastward. That will leave our area in the wake of the
weakening upper trough and ahead of a potent upper level low
centered just to the north of lake superior. Weak subsidence in the
wake of the departing upper trough could keep us dry for a change on
Thursday. The 00z deterministic GFS and euro both keep us dry
on Thursday. However, a few members of each respective ensemble
produce some precipitation. With a warm airmass in place and
dewpoints in the 60s, an afternoon shower or storm can't be entirely
ruled out. However, the trend on Thursday seems to be in favor of
On Friday, the aforementioned upper low will continue to progress to
the east across southern canada. This trough will drive a weak
surface cold front toward our area from the north. The best forcing
for ascent associated with the upper low looks to stay north of our
area. However, both the GFS and euro hint that a few storms may be
possible along and just ahead of the front. The trough has an
extensive wind field associated with it, with decent mid-upper level
flow extending down to our latitude. Currently models show around
1000 j kg of MLCAPE with 35-40 kt of 0-6 km shear Friday afternoon.
Although coverage of storms looks to be low, those parameters
suggest that if storms were to form, they could show some
Beyond Friday, model guidance begins to diverge. Temperatures should
be a few degrees cooler for the weekend in the wake of the front.
However, the front won't entirely clear low level moisture (and it's
associated convective potential) out of the area. Both the eps and
gefs have precipitation producing members Saturday and Sunday, but
there doesn't to be a clear solution in either the deterministic or
Aviation 08z Monday through Friday |
Widespread showers t-storms expected today into Wed with
training convection likely. Expect MVFR ifr conditions at most
taf sites for a few hours this afternoon into evening.
Conditions begin to improve late Wed night.
Sca conditions likely through Wed night. Mariners can expect
higher winds and waves near thunderstorms.
Repeated rounds of showers and thunderstorms through the first
half of the week will lead to increasingly susceptible
conditions for not only flash flooding but eventually some river
flooding. Flash flood watches and river related products will
likely be extended through wed, and those with sensitive
interests will want to start making plans.
Tides coastal flooding
Gusty southerly flow will continue to lead to elevated water
levels for the next several days. Multiple coastal flood
advisories are in effect through Tue morning. Coastal flood
watch issued for annapolis for the Tue morning high tide. The
overnight high tides will be favored. Daily fluctuations are
proving difficult to pinpoint though, so adjustments to the
forecast are likely.

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.
