Synopsis
High pressure crosses tonight. Temperatures and dewpoints on
the increase through the end of the week. Cold front late
Saturday Saturday night.

Near term through Wednesday
As of 925 pm Tuesday...

models appear to be on track. Most of the diurnal clouds that
developed today have dissipated and winds around the area have
become light.

Temperatures have cooled into the 60s in most locations with 50s
across the highest elevations. Latest temperature guidance
continues to indicate the forecasted lows tonight are very
reachable.

As what usually happens, the MOS guidance for our cooperative
observer locations based on the GFS indicates temperatures in
rural areas will be several degrees cooler than the more urban
sites. One example of this is that this guidance shows the low
temperature at our office will be in the upper 40s while the low
in the lower 50s at the charleston airport, the official
observation site, looks good.

As of 230 pm Tuesday...

models continue to settle canadian high pressure directly over
the area tonight, allowing for clear skies after some afternoon
cumulus clouds, and near calm winds. This will bring ideal
radiational cooling conditions tonight. Little change to
previous thinking concerning low temperatures tonight, which
remain close to but just above record values in the major
metropolitan areas. However, record lows may be reached in the
more protected valleys by dawn Wednesday. These lows we have
forecast are actually on the low side of the vast majority of
guidance, but cannot neglect the ideal cooling scenario. In
addition, despite the dry air in place, there will likely be
some river valley fog later tonight, mainly at crw and ekn. So,
will not get carried away with the fog given the dry air in
place.

For Wednesday, the high moves off to the east with a southerly
flow developing. Under abundant sunshine and still relatively
dry air, temperatures will rebound to around 80 degrees or so.

Forecast lows tonight are close to records in some cases:
location forecast low tonight record year
crw charleston 51 50 1988
hts huntington 51 47 1915
pkb parkerburg 50 48 1988
ekn elkins 43 39 1988
bkw beckley 49 39 1955
ckb clarksburg 49 46 1927

Short term Wednesday night through Friday
As of 305 pm Tuesday...

slow retreat of canadian high pressure off the coast will
translate into warming temperatures through the end of the week
with primarily dry weather, although the northwest zones will be
exposed to low chances from northern stream upper level energy.

No major changes to the forecast overall.

Long term Friday night through Tuesday
As of 305 pm Monday...

shower and thunderstorm chances on the increase with an arriving
cold front and upper level trough spinning through the great
lakes. Without a clean passage of the upper low, with it only
rotating northward as oppose to eastward, the unsettled weather
will tend to linger with the front taking some time to finally
exit the mountains.

Aviation 01z Wednesday through Sunday
00z Wednesday thru 00z Thursday...

as of 755 pm Tuesday...

latest satellite imagery and surface reports indicate the
diurnal clouds that developed today have begun to dissipate.

This trend should continue leaving the region with clear skies
by 03z.

High pressure will push east across the area tonight. Clear
skies and calm winds will result in favorable radiational
cooling. As a result, believe river valley fog should form
after 06z with some locations, such as ekn and crw, seeing ifr
or lower conditions from 07z-12z.

Once the fog dissipates on Wednesday,VFR conditions should
prevail with mostly clear skies and light southerly winds.

Forecast confidence and alternate scenarios through 00z Thursday...

forecast confidence: high, but medium tonight for fog.

Alternate scenarios: river valley ifr fog later tonight may vary
from forecast.

Experimental table of flight category objectively shows consistency
of WFO forecast to available model information:
h = high: TAF consistent with all models or all but one model.

M = medium: TAF has varying level of consistency with models.

L = low: TAF inconsistent with all models or all but one model.

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.
