Synopsis
Lingering showers across the eastern half of the area this
morning. An upper level low will be slow to lift away to the
northeast over the weekend.

Near term through tonight
As of 400 am edt Saturday...

improving conditions for most early this morning with lingering
mostly light to moderate rain near and east of i-95. One last
area of showers with some embedded thunder will continue to
impact coastal locations through 8am or so. A few areas of
generally weak rotation noted in the strongest storms over NE nc
early this morning but overall the severe threat has diminished
considerably. Will allow the remaining flash flood watch to
expire on time early this morning.

The upper low to our west will be slow to lift northward today
which will keep partly to mostly cloudy skies in the forecast
for today. A few showers may develop across the western half of
the region this afternoon due to cooling temperatures aloft
associated with the upper low. Highs this afternoon will range
from the mid 60s across the west where cloud cover is expected
to be thicker to the low 70s from roughly i-95 to the east.

Overnight temperatures will cool into the upper 40s W to low 50s
e.

Short term Sunday through Tuesday night
As of 400 am edt Saturday...

clouds associated with the slow-moving upper low will stick around
on Sunday with isolated showers possible across most of the region
through the afternoon hours. Highs on Sunday will top out in the mid
60s with overnight lows in the upper 40s and low 50s. The upper low
will open into a trough and finally lift out of the region Sunday
night and Monday allowing skies to clear from southwest to
northeast. Increased sunshine will send afternoon highs back into
the 70s for Monday with overnight lows in the 50s. Tuesday will be
warmer still with temperatures generally in the low 80s inland and
mid to upper 70s near the water and across the eastern shore.

Long term Wednesday through Friday
As of 330 pm edt Friday...

the extended period begins with the upper trough that will
impact the region this weekend finally exiting the area and a
stronger upper level ridge building in and across the
southeastern us. As the ridge builds in, expect to see a period
of warmer weather and also drier conditions on Tuesday.

There is a great deal of uncertainty from Wednesday through
Friday however as several shortwave troughs try to break down
the SE ridge and push a surface front through the area. The
models are showing little consistency between themselves and
little run to run consistency either. The 00z ECMWF was quicker
to push the surface front south of the area as it was more
progressive with the upper level shortwave trough and had the
surface front south of the region by Thursday before lifting it
back north on Friday. The 12z GFS on the other hand was slower
to move the front through waiting until Thursday night to push
the front through as a stronger northern stream trough
approaches on Friday. Then the 12z ECMWF completely changed
things by being so slow that is never has the front reach the
area and amplifies the upper trough over texas and holds the
front northwest of the area into Friday night. So confidence in
the over pattern is low. For now, have added a generally low
chance of showers into the forecast from Wednesday into Friday
and it will all be dependent on the position of the front.

For temperatures, have gone a touch warmer on Tuesday into
Wednesday with readings in the upper 70s to the lower 80s. But a
touch cooler on Thursday and Friday with readings in the mid
70s. But if the front does stay to the north, readings could be
a little warmer toward the tail end of next week. Overnight lows
should stay on the milder side in the 50s across the region.

Aviation 08z Saturday through Wednesday
As of 130 am edt Saturday...

the bulk of the heavy showers and storms have moved off the
coast but another area of showers with occasional thunder is
moving northward into the area. Bkn to ovc MVFR CIGS are in
place across much of the area and are expected to continue
through about 12z before lifting toVFR. Southerly winds 10 to
15 knots will continue through the 06z TAF period with gusts 20
to 25 knots.

Outlook: upper low will be slow to move into and acrs the region
sat evening into early Mon morning. This will result in more
clouds (still mainlyVFR cigs), esply over ric sby phf, along
with a slight chance of showers.

Marine
As of 315 am edt Saturday...

low pressure will be slow to exit the region during the
weekend. Will maintain a S wind 20-25 kt (gusts to 30kt mouth of
the ches bay ocean) to start then mainly 15-20 kt today (aob 15
kt on the rivers), becoming SW tonight, continuing Sunday w
further lowering of speeds expected. Scas up for rivers sound
until 10z 20... The ches bay until 22z 20 and on the ocean until
10z 21 (which may need extended a little longer due to seas slow
to fall blo 5 ft). Mainly SW winds AOB 15 kt over the local
waters mon-tue.

Tides coastal flooding
As of 350 pm edt Friday...

latest guidance depicts potential minor tidal flooding for the
bay-side of the lower md ERN shore where tidal departures are
expected to average 1.0-1.5ft mllw. Additional minor flooding
is possible along the albemarle sound with a strong S wind. A
coastal flood advisory has been issued for the md ERN shore from
midnight to 7 am Saturday, and a coastal flood statement has
been issued through 8 am Saturday.

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.
