Synopsis
High pressure over the lower mississippi valley will move east
and off the southeast coast tonight. A cold front will move
through the eastern united states Tuesday night, followed by
high pressure on Wednesday and Thursday. Another cold front will
cross the region this weekend.

Near term through tonight
As of 210 am edt Monday...

upper trough and colder air aloft over the northeast united
states move east today. 500 mb pattern over the mid atlantic
region gradually becomes southwest ahead of the next northern
stream trough. Colder air at 850mb is retreating too. By Tuesday
morning 850mb temperatures will be in the +6 to +8 range over
southeast west virginia, southwest virginia and northwest north
carolina.

At the surface high pressure moves from the tennessee valley to
off the carolina coast by this evening. Expect the high to be
far enough offshore tonight that winds will slowly increase from
the southwest over the ridges overnight. Even surface winds in
the foothills and piedmont may not decouple.

Clouds and moisture along the western slopes all below 850mb.

Model show clearing before 9am then little to no clouds for the
rest of the day and tonight. Will be staying close to national
blend and bias corrected mav for highs today and lows tonight.

Short term Tuesday through Thursday night
As of 145 pm est Monday...

shortwave ridging will slowly weaken Tuesday as surface high
pressure slides offshore in advance of both northern southern
stream shortwaves within the split flow regime. These features
still remain just out of phase with only a couple solutions
pulling enough moisture north for showers Tuesday night as the
southern surface low passes off the carolinas. Since the latest
ensembles show a few showers both across the east, and also
northwest with the northern piece of energy will keep in some
low pops in spots Tuesday night. High pressure following these
systems to bring drier weather including a quick punch of cooler
air on brief gusty winds Wednesday before the gradient
diminishes by Wednesday night. We will see another short wave
trough track a disturbance off the carolina coast Thursday and
Thursday night. Rain with this system will remain along the
coast with only an increase in high clouds for the area.

Highs mid 50s to lower 60 Tuesday before cooling back to 40s
mountains and 50s east per cool advection Wednesday and
Thursday. Cold air slow to come in Tuesday night with most areas
staying above freezing (mid 30s to lower 40s). Temperatures
fall into the 20s across the mountains and 30s east Wednesday
and Thursday night.

Long term Friday through Sunday
As of 200 pm est Sunday...

overall upper troffiness to prevail through the period with
reinforcing energy arriving next week that looks to carve out
an even deeper 500 mb cold pool. Will see low pressure develop
offshore the carolinas later on thanksgiving within split upper
flow early on but appears too far offshore for any showers at
this point. Otherwise should see mainly dry weather under weak
high pressure and overall below seasonal temps until a strong
cold front arrives Saturday. This front will again be followed
by colder temperatures next Sunday similar to this weekend.

Appears a few western rain showers possible ahead of the front
Saturday night, followed by western snow showers early Sunday,
but little more than low pops for now.

Aviation 12z Monday through Friday
As of 625 am est Monday...

MVFR clouds on the west slopes of the appalachians were rapidly
eroding this morning. High confidence ofVFR conditions across
southeast west virginia, southwest virginia, and northwest north
carolina today and tonight. Winds will be from the west today as
high pressure moves through the tennessee valley and off the
southeast coast. Return flow around the high late tonight will
produce an increasing southwest low level jet. The highest
elevations may have gusts up to 25 knots.

Extended discussion...

mainlyVFR conditions are expected Tuesday into Friday.

Exceptions would be some lower CIGS with a front trough tue
night-wed in the mountains, and again thanksgiving. With the
flow aloft mainly northwest, no appreciable amounts of moisture
or precipitation are expected through the week.

Rnk watches warnings advisories
Va... None.

Nc... None.

Wv... None.

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.
