Synopsis
Low pressure will move off to the northeast this morning. High
pressure resumes control as the low departs an and remains over
the region through the weekend and into next week.

Near term through Saturday
As of 450 am fri... Upper level low analyzed on h2o vapor
imagery over the central appalachians will eject NE toward new
england through the day today. Resultant w-sw downslope flow
will help to quickly scour out clouds this morning, and
scattered clouds are observed at area ASOS awos. Meanwhile,
surface high pressure rebuilds from the west late today into
Saturday, bringing a mostly clear sunny sky late Friday into the
weekend. Weak CAA at the surface will maintain temperatures
near or just below seasonal averages. Highs generally in the 50s
today Saturday and lows in the 30s inland to low 40s for
coastal SE va NE nc Saturday morning..

Short term Saturday night through Sunday
As of 325 pm est Thursday...

high pressure at the surface builds overhead into the upcoming
weekend, with a quieter, quasi-zonal flow aloft bringing a dry,
quiet wx weekend across the local area. Maxima do moderate through
Sunday, but temperatures look to remain at or just below climo
norms. Expect highs generally in the 50s to near 60 with early
morning lows generally into the low to mid 30s inland to around
40 at the coast.

Long term Sunday night through Thursday
As of 345 pm est Thursday...

much quieter weather still on track for much of next week. A weak
upper-level shortwave approaches the area late Sunday-Monday
(coupled with a sfc cold front). Not much in the way of rain
expected with the fropa, but have slight chc pops for coastal NE nc
from 06-18z mon. Looks like the bulk of the rain will fall well
offshore after the front crosses the CWA by Mon aftn. Behind the
front, sfc high pressure settles just west of the region Mon night-
tue. However, am only expecting temperatures to drop to slightly
below average. A weak shortwave caught in NW flow aloft is progged
to swing through the mid-atlantic on Wed (coupled with another cold
front). However, moisture will be lacking across the area, so this
will be another (mainly) dry fropa. Canadian high pressure then
settles over the region on Wed night-thu am before moving offshore
by the end of the day on thu.

The cooler air lags behind the front a bit, so highs on Mon will
still be in the 50s to near 60. Cooler on Tue wed, with highs in the
upper 40s to near 50 north mid 50s south. Warming back up into the
50s area-wide on thu. Lows Monday night in the low-mid 30s
inland around 40 in coastal SE va-ne nc. Cooler on both Tuesday and
Wednesday night with lows ranging from near 30 NW to the mid-upper
30s se.

Aviation 10z Friday through Tuesday
As of 110 pm est Thursday...

deepening sfc low continues to lift n-ne along the carolina
coast this late this evening, bringing widespread ifr ceilings
and patchy reduced visibility in fog drizzle. Breezy to gusty
wind will occur through the night. Conditions will improve from
southwest to northeast across the terminals Friday morning,
withVFR conditions ensuing within a couple of hours after
sunrise at the latest.VFR conditions prevail through the rest
of the TAF period.

Outlook: high pressure prevails Friday night through Monday
with continuedVFR conditions expected.

Marine
As of 450 am est Friday...

low pressure exiting the region this morning. Strong pressure
rises in wake of departing low means strong wsw winds up to
gale force being observed across parts of the marine domain.

Winds have diminished enough to replace gales with SCA for all
but northern 2 3 of the coastal waters. Winds over the rivers
will diminish below SCA by late morning, then for the chesapeake
bay by mid evening tonight. Seas will follow suit by subsiding
below 5 feet tonight.

Calmer conditions return for the weekend as high pressure
settles back over the region.

Hydrology
As of 450 am est Thursday...

river flood warnings remain in effect for stony creek on the
nottoway, and mattoax on the appomattox, lawrenceville on the
meherrin and sebrell on the nottoway. Palmyra on the ravanna.

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.
