Synopsis
The remnants of nestor will push offshore of the outer banks by
this evening. High pressure will briefly return for Monday. A
cold front will cross the region Tuesday. High pressure will
follow for Wednesday and Thursday. Another storm system may
approach the mid-atlantic by the end of the week.

Near term through Monday
Mid-level dry slot has pushed through the area already with back
edge of mid-level moisture plume over the chesapeake bay. Light
rain still lingers across eastern areas but should quickly
dissipate or end by 21z. However, a low overcast is expected to
persist through the evening with partial clearing expected in
some areas overnight. This could lead to some areas of dense
fog. Otherwise, widespread stratus clouds expected overnight
into Monday morning.

Warmer tomorrow under partly sunny skies with sfc ridge in
control. Warmer with highs in the mid to upper 60s.

Short term Monday night through Tuesday night
Next frontal system is expected to approach the area Tue with
prefrontal showers expected to move into our area late Monday
night (after 06z tue). Expect widespread showers Tue as cold
front crosses the area and area of low pressure forms to the
south and crosses the area. Rainfall amounts with this system
will be lighter with amounts generally in the quarter to half
inch range. Showers should exit the area Tue evening.

Long term Wednesday through Sunday
High pressure will build over the region Wednesday and Thursday,
before sliding offshore on Friday ahead of an approaching low
pressure system out of the southeast. This will result in dry days
on both Wednesday and Thursday, and even most of Friday. High
temperatures each day will be in the low to mid 60s, with Thursday
being the coolest of the three days. Overnight lows will be in the
mid 40s on Wednesday and Thursday.

Meanwhile, a very strong mid upper level trough will be sliding out
of the northern plains and digging deep into the southeastern u.S.

By the end of the week, and possibly cutting off. This upper-level
energy will interact with the baroclinic zone along the gulf coast
to form an area of surface low pressure somewhere in the lower
mississippi river valley. From there, where the low GOES is a little
up in the air at this point. Will be dependent on if the system cuts
off from the main trough axis or not, which would result in a slower
moving system sliding by to our west. Whereas, if the system were to
remain embedded within the main trough axis, it would likely ride up
the east coast. Either way, some rain will be possible late week
into the weekend.

Aviation 19z Sunday through Friday
Ifr lifr CIGS tonight with areas of 3-5sm vsby. Conditions
improving late tomorrow morning. Northerly winds 10-15kt
diminishing tonight. Next frontal passage expected late Tue with
showers expected late Monday night through Tuesday.

Vfr conditions expected on Wednesday and Thursday, as high pressure
builds overhead.

Marine
Gale warning issued for the southern waters as a few gusts to
34kt have been seen recently. Model trends indicate winds will
should increase through 00z tonight then diminish after
midnight. Scas may be needed again Tuesday afternoon and night
on sse winds.

Small craft advisories may be needed on Wednesday, with some gusty
winds leftover after the frontal passage. These should die down by
Wednesday evening, and definitely into Thursday, as high pressure
builds overhead.

Tides coastal flooding
Issue cf.Y for st. Marys, king george, and prince georges county
where anomalies are up to 1.7 ft and still rising. Water levels
should begin to drop late tonight as winds become more
northerly.

As winds go light and then southerly by late Monday, these
anomalies will come back up the bay and tidal potomac river,
probably resulting in flooding through Tuesday. Offshore flow
should then cause water levels to decrease by Wednesday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
