Synopsis A broad and slow moving low pressure system will
drop from the ohio valley into the southeast by Monday. This
low will continue to influence the mid atlantic during the early
part of the week.

Near term through tonight
Precip today will be less organized than yesterday due to
weaker forcing which makes the location of the showers much more
difficult to pinpoint. Despite rain deluge yesterday and
significantly lower FFG values, am leaning toward no flood watch
for today attm. First, the big plume of pw air >2.0 inches is
expected to remain offshore through tonight, precip should be
less organized, and model signal for heavy rain is not that
strong. Think any flooding problems today will be localized and
difficult to pinpoint at this time.

Short term Monday through Tuesday night
Plume of very high pw air >2.0 inches is expected to shift more
westward inland as upper low drops into the southeast and
heights rise along the coast. Fcst wind profiles indicate strong
unidirectional flow very conducive to training convection and
model signal for heavy rain is stronger with widespread
convection. Will likely see more scattered incidents of flooding
and a flash flood watch will likely be required for Mon and tue.

Locations along and east of the blue ridge into northeast md
appear at greatest risk of experiencing flash flooding.

Long term Wednesday through Saturday
A trough of low pressure will remain stationary through Thursday. A
persistent train of moisture pushing up from the south will interact
with this trough to produce showers and thunderstorms. Much of the
shower and thunderstorm activity should occur during the warmest
time of the day in the afternoon through the early evening hours
each day. Precipitable water values of 1.75 inches to 2.25 inches
will aid in heavy rainfall within the shower and thunderstorm
activity. High temperatures will be slightly below normal and low
temperatures will be slightly above normal due to cloud cover and
showers and thunderstorms.

The trough of low pressure will gradually push east Thursday night
and Friday. Because the trough is not expected to move too far to
the east and possibly become stationary across the delmarva
peninsula or tidewater of virginia Friday, the chance for showers
and a few thunderstorms may linger Thursday night and Friday. The
farther northwest and northern zones may encounter a few showers
Thursday evening, briefly become dry overnight Thursday and Friday
morning, then follow up with showers and a couple of thunderstorms
Friday afternoon. There is some uncertainty as to how far the trough
moves eastward, the strength of the trough, and coverage of showers
and thunderstorms. High temperatures will be closer to normal as we
could see a southwest wind develop along a weak front.

Weak high pressure makes an attempt to dry us out Friday night and
Saturday, but could soon be followed up by an approaching upper
level disturbance from the west Saturday night and Sunday. This
upper level feature could bring a warm front northward and a couple
rounds of showers and thunderstorms along it or behind it.

Temperatures will be close to normal.

Aviation 08z Sunday through Thursday
MVFR ifr CIGS early this morning should improve shortly after
sunrise. Sct t-storms expected today which may result in brief
MVFR ifr CIGS vsbys. Unsettled wx will continue through mid
week.

Showers and thunderstorms each day through Thursday. The warmest
time in the afternoon into the early evening hours would be the more
prominant time to encounter these showers and thunderstorms.

Occasionally MVFR or perhaps ifr could develop with the showers and
thunderstorms. Winds generally southeast to south at 5 to 10 knots
with higher gusts in thunderstorms through Wednesday night. Winds
could become southwesterly at 5 to 10 knots Thursday ahead of the
trough. Winds could shift to more westerly later Thursday night and
Friday with a trough moving across the region.

Marine
Sca conditions possible through Tue night. Winds and waves
locally higher in t-storms.

Small craft advisories possible Wednesday and Wednesday night for
the main stem chesapeake bay near and around the tidal potomac.

Winds southerly around 10 knots gusts to 15 to perhaps 20 knots
Wednesday and Wednesday evening. Winds becoming southwest to
westerly 5 to 10 knots gusts 15 knots Wednesday night and
Thursday.

Tides coastal flooding
Will likely be issuing coastal flood watch for annapolis for
tonight's high tide into early Mon due to gusty southerly flow.

Minor coastal flooding is also expected at dc waterfront likely
through the middle of the week.

Lwx watches warnings advisories
Dc... Coastal flood advisory until 10 am edt Monday for dcz001.

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.
