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

Near term through Monday
As of 725 pm Sunday...

only minimal changes made to previous forecast to better reflect
current obs and trends.

As of 120 pm Sunday...

weak high pressure keeps the CWA dry and warm today. A minor
impulse at 500 mb passes to our north overnight though trended
towards SREF and GFS ensembles keeping the forecast dry. There
should be fog again in the river valleys overnight though the
impulse and a full day of Sun today may lessen the density and
extent overnight. Despite this, still kept a general mention of
fog in the river valleys.

Monday high pressure holds on albeit weakly, but should be
enough to keep us dry again with minimal cloud cover except in
the mountains where daytime heating may be enough to spark a few
isolated showers.

Short term Monday night through Wednesday night
As of 230 pm Sunday...

5h trough digs southeast into the great lakes with an
accompanying front at the surface. This feature will drive a
colder airmass of continental canadian air into the eastern us
by Wednesday night. Have front pegged to be along the ohio river
along the wv-oh border at around 06z Wednesday and this feature
will drive shower and isolated thunderstorm activity across the
forecast area with decent wetting rains. Made some adjustments
to the model blend pops by just a few hours but generally
accepting guidance.

Long term Thursday through Sunday
As of 230 pm Sunday...

cool period in the long term as canadian airmass in control of
our sensible weather. Surface high dominates the eastern
seaboard. Used guidance throughout the period.

Aviation 00z Monday through Friday
As of 725 pm Sunday...

expecting dense river valley fog to form again tonight, however
with an upper level impulse passing just north of the forecast
area there is a potential for some clouds playing havoc with fog
formation. This impulse may also keep some flow going... Again
having an adverse affect on fog formation.

Fog will dissipate quickly after sunrise withVFR through the
remainder of the TAF period. An isolated shower is possible
across the northern mountains counties Monday afternoon.

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

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

Alternate scenarios: timing and density of fog may vary based on
clouds and some remaining flow.

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. 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.
