Synopsis
High pressure Sunday through Tuesday. Strong cold front late
Tuesday Tuesday night. Cooler and drier for the end of the
week.

Near term through tonight
As of 1050 am Sunday...

no changes.

As of 630 am Sunday...

no changes.

As of 255 am Sunday...

weakening east to west surface boundary across southeast oh and
central WV at 06z will dissipate Sunday morning as weak high
pressure takes over. Isolated convection continues to diminish
overnight as drier air aloft spreads over the area, and should
be gone before dawn. However, mostly clear skies and calm winds
early this morning will lead to some dense valley fog,
especially where it rained earlier. Fog will burn off shortly
after dawn, leaving abundant sunshine under the weak high
pressure for Sunday. The high pressure center itself shifts just
far enough east this afternoon to turn low level winds to a
southwesterly component, but with a more southerly component
east of the mountains. This will lead to modest low level
convergent flow east of our mountain ridges with modest pooling
of low level moisture. However, it looks like models keep this
zone just east of our forecast area, so that any isolated
afternoon convection is expected to stay just east of our
mountain counties over western va. So, no pops in the forecast
today. It will be very warm and just a bit more humid with a
slight increase in low level moisture, with highs near 90
degrees under abundant sunshine. Tonight looks to be tranquil
and mild as the weak high pressure system still controls our
weather.

Short term Monday through Tuesday night
As of 230 am Sunday...

accounting for the eclipse in the temperature grids on Monday
afternoon by using modest hourly temperature reductions from
18-20z given the sky cover in the 20-35 percent range.

Digging trough aloft into the great lakes will drive an airmass
changing cold front late Tuesday and Tuesday night, with
increasing flow out ahead of the system. Better dynamics will be
further northeast of the area, but thunderstorms are possible
upon entrance into the CWA late Tuesday, but will erode as the
front moves through in the late evening overnight time frame.

Long term Wednesday through Saturday
As of 230 am Sunday...

should run 10-15 degrees cooler in both temperature and dewpoint
in the wake of the front as canadian high pressure brings
pressure rises back into the middle ohio valley and central
appalachians. The western CONUS ridge eastern CONUS trough
setup will persist, with high pressure holding through the
weekend. The long term will be largely dry, with temperatures
very gradually ticking upwards.

Aviation 15z Sunday through Thursday
12z Sunday thru 12z Monday...

as of 1030 am Sunday...

weak high pressure forVFR until more river valley fog after
06z, especially at ekn and crw.

Forecast confidence and alternate scenarios through 12z
Monday...

forecast confidence: high, except low to medium with fog.

Alternate scenarios: timing, density, and location of river
valley fog tonight could vary.

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.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
