Synopsis
High pressure moves across the southeastern states through
tonight, then slides offshore through Tuesday morning. Low
pressure will move northeast along the mid atlantic coast
Tuesday night ahead of a cold front that pushes offshore
Wednesday.

Near term through tonight
Latest weather analysis reveals ~1026mb surface high pressure
over the lower mississippi river valley and the mid-south. The
surface high will slide across the carolinas this afternoon,
before sliding offshore late tonight. Lingering mid clouds have
abated over northern mid-atlantic DELMARVA this morning, and
expect plenty of sunshine later this morning and this afternoon.

Highs today mainly in the upper 40s to near 50 on the eastern
shore... To lower 50s inland. Mainly clear tonight with lows in
the upper 20s to mid 30s.

Short term Tuesday through Wednesday night
The sfc high slides off the coast to begin the day on Tuesday.

Resultant strengthening return flow initiates a short-lived
warming trend, with highs 60-65. After a sunny start, some mid
to high clouds begin to filter in from SW to ne. A quick moving
northern stream system lifts from the tn valley into the
northeast Tuesday night into Wednesday, pulling a cold front
east to the atlantic seaboard by Tuesday night. Weak sfc low
lift n-ne along the carolina mid-atlantic coast Tue night and
wed. Moisture from the system lifts north with the best lift
remaining along the coast. Expect a period of showers mainly
along and east of i-95 after midnight Tuesday night early
Wednesday morning. Likely pops along the bay and coast... Chc
pops inland. Chc pops along the md coast Wed morning then drying
out. QPF generally under one quarter inch. Lows Tue night in
the 40s to near 50 se. Highs Wed in the 50s except near 60
across nern nc.

Long term Thursday through Sunday
High pressure builds into the area Thursday resulting in a dry but
cool holiday. Lows Wed night in the 30s to lwr 40s se. Highs thurs
in the upr 40s to lwr 50s.

Another area of low pressure develops off the SE coast late in the
week but it appears the high to the north keeps any significant
moisture south of the local area. Dry and continued cool fri.

Highs 50-55. Next cold front approaches from the NW late sat
then crosses then area early sun. GFS wetter than ECMWF so will
go with low chc pops Sat night for now. Warmer Sat ahead of it
with highs 55-60. Lows Sat night in the 40s to near 50 se.

Cooler behind it Sun with highs mid 40s-lwr 50s.

Aviation 09z Monday through Friday
Vfr conditions across area terminals early this morning, with
vfr conditions to prevail through the TAF period and into
midweek, as high pressure builds back into the region later
today through this evening.

Outlook: high pressure slides offshore late Monday night and
Tuesday. A trough of low pressure develops along the carolina
coast Wednesday with scattered showers possible at area
terminals by later Tuesday into early Wednesday. A brief period
of sub-vfr conditions are possible over the terminals during
this timeframe.

Marine
Sca flags cancelled for mouth of james river and currituck
sound as high pressure builds over the southeast states and
the pressure gradient relaxes. This trend will continue through
today. W-nw winds 15-20kt primarily occurring on east side of
ches bay and ocean (gusts up to 25-30kt north of parramore
island). There is a good chance that SCA flags for coastal
waters from chincoteague to currituck light will expire be
cancelled by 700 am.

Otherwise, relatively quiet conditions anticipated the rest of
today through tonight as high pressure becomes centered over
the carolinas and slides offshore late tonight. W-nw winds
becoming s-sw tonight with sub-sca speeds. A canadian low
pressure system will drag a cold front into the ohio valley
tue... Approaching the waters late Tue night. Pressure gradient
tightens over NRN half of area during this time. SW winds
should average 10-15kt north 5-10kt south Tue and diminish
through Tue night as wind direction becomes more westerly late.

Seas 2-4ft north 2-3ft south this aftn through Tue night. Waves
generally 1-2ft. Meanwhile, low pressure develops off the
carolina coasts and tracks northeast... Passing well east of
cape hatteras by Wed aftn. Next chance for SCA conditions
should be Wed wed night for all waters except york, rappahannock,
and upper james rivers. Seas 3-5ft; waves 3-4ft. High pressure
rooting itself over the ohio valley to tn mid-mississippi
valleys Wed night through Thu night will allow another low
pressure wave to track northeast from the southeast coast to
an offshore location farther east of CAPE hatteras during this
time. Best pressure gradient appears to stay well south of the
local waters, therefore sub-sca n-nw wind speeds are anticipated.

Seas slowly subside from 3-5ft Thu to 2-4ft Thu night fri.

Waves 2-3ft subsiding to 1-2ft during same timeframe. High
pressure builds into the mid-atlantic region for Fri with light
and variable winds expected.

Equipment
The fan on the temperature sensor at the richmond ASOS (kric)
has likely failed, causing erroneous temperature readings. The
contract observer is augmenting the official METAR observations
(hourly METAR and specis). However, the 5-min high resolution
data is automated directly from the sensor and is subject to
reporting this erroneous data. As such, do not rely on the 5 min
temperature data from kric until our techs can repair the
sensor, likely on Monday.

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.
