Synopsis
High pressure will prevail over the mid-atlantic through
Thursday. Low pressure approaches from the southwest Thursday
night into Friday, and tracks across the region Friday afternoon
through early Saturday. An upper level trough will remain over
the area through Sunday.

Near term until 6 am Thursday morning
As of 900 pm est Wednesday...

latest msas has high pres over the area with weak warm front
lifting north from ohio to near the mason-dixon line. Clouds
assctd with weak S W trofs both to the south and NW continue
to cross the region with sfc obs Sat loop showing periodic
mid high level clouds along with a light south wind.

Temps much slower to drop this eve than recent nights, with
only a few sites AOB freezing versus widespread freezing temps
from 24 hrs ago. In fact, tonights hrly temp guid is showing
readings not falling much from the current values. However,
not sure if the remaining snow cover plays into this, so will
keep fcstd lows below guid with this update. Lows from the mid
20s-lwr 30s except mid 30s SE cstl areas.

Short term 6 am Thursday morning through Saturday
As of 400 pm est Wednesday...

dampening upper trough pushes across the northeast tomorrow,
with weak sfc trough pushing just north of the local area
Thursday morning. Meanwhile, high pressure builds across coastal
new england and ridges south into the local area. Sct-bkn mid to
high clouds will once again prevent temperatures from warming
very quickly Thursday, and have once again opted toward the
cooler end of guidance, though dewpoints rising into the low mid
30s should hasten snow melt a bit further. Highs in the mid to
upper 40s inland, to the low mid 50s in SE va NE nc.

The aforementioned SRN stream system will interact with northern
stream energy dropping across the canadian rockies this
afternoon. This will carve out a a broad upper low, which will
close off over ERN tx la by late Thursday, with a moist frontal
band emerging from the gulf into the deep south ahead of the
low. Continued dry across our area Thursday night with lows in
the low 30s inland to the upper 30s low 40s at the coast.

The upper level system traverses the deep south Friday into
Friday night, as the moist frontal band pushes toward the mid-
atlantic Friday aftn into Friday night. 12 12z models have
slowed slightly, but generally remain in good agreement with a
warm and wet pattern prevailing Friday aftn into Saturday
morning. Storm-total QPF has stepped up once again... Which makes
sense given strong forcing and favorable dynamics... With
1-1.75" expected across the local area with amounts up to
2.0-2.25" possible through 00z Sunday. This combined W saturated
ground and additional moisture released from snowmelt will
bring potential flooding. A flood watch will almost certainly be
needed for at least a portion of the local area with later
forecast packages if current setup remains in place in modeled
data, and will continue to make a mention in hwo, given pops in
the 70-90% range. Latest mmefs still depicts minor river
flooding with moderate flooding possible.

Long term Saturday night through Wednesday
As of 355 pm est Tuesday...

still some model differences in the long term, but it is appearing
likely that showers will linger into at least Sunday afternoon. Both
12z ecm and canadian have the upper level low pressure system moving
further to the south (over north carolina) while the 12z GFS brings
this low pressure further north over virginia. Fv3 also agrees with
the ecm canadian on general low placement, but is drier compared to
the other models. Have trended towards the more southern placement
of the upper level low, thus have trended pops upward during the day
Sunday. Both the ecm and canadian show surface cyclogenesis off the
nc coast late Sunday into Monday, allowing for the threat for rain
to continue across the east into overnight Sunday. Through this
period, the ecm is the most aggressive with qpf, showing an
additional 1.00" plus of precipitation for portions of the region
while the american models are much drier during this timeframe.

Temperatures on Sunday will range from the upper 40s NW to the
mid upper 50s further se. Low temperatures will range from the
low mid 30s to the lower 40s.

By Monday afternoon, high pressure returns to the area bringing dry
weather for the remainder of the long term period. Temperatures will
trend cooler by Monday with high in the lower 50s on Monday and only
mid to upper 40s for Tuesday. Overnight lows will range from the 30s
to upper 20s.

Aviation 02z Thursday through Monday
As of 610 pm est Wednesday...

vfr conditions through the forecast period. Bkn high level clouds
tonite with sct-bkn sc developing thurs over the north. Ssw winds
aob 5 kts.

Outlook:
low pressure approaches from the SW Fri and moves across the area
fri night into Sat bringing rain and degraded flight conditions.

An upper level trough lingers over the area into sun.

Marine
As of 400 pm est Wednesday...

tranquil marine conditions will remain in place through Thursday
night as high pressure will dominate our local weather. Longer term
model guidance shows low pressure impacting the area late Friday
through the weekend. For now, winds looks to remain sub-sca for the
most part through the weekend. E-se winds 10-15 kt Fri aftn will
become s-sw Sat morning, the variable Sat aftn. Winds then become n-
ne on Sunday. Winds become NW 10-20 kt to start next week behind the
departing system. Seas are expected to increase starting Friday
night and then remain elevated over the weekend. Scas will likely
need to be issued for this.

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.
