Synopsis
A cold front crosses this morning. High pressure crosses
tonight. Warmer, more humid and unsettled latter half of the
week. Cold front crosses by Sunday but returns early next week.

Near term through tonight
As of 420 am Tuesday...

a cold front crossing the ohio river early this morning is
likely to become better defined in the surface wind field on
mixing after sunrise, but then may become more difficult to find
as it jumps the mountains late this morning. Models insist
showers break up ahead of the front this morning, as thin mid
level CAPE gives way to mid level drying. The chance for midday
or early afternoon thunder in the mountains is very small
though not quite zero.

High pressure builds in for a clear, calm, cool night tonight.

Short term consensus blend close to previous and mav for highs
today, the mav was a bit high. Mav met previous short term
consensus blend used for lows this upcoming radiative cooling
night, at or a little below previous. GFS based MOS has had 45
at ekn for days, as has the forecast.

Forecast lows tonight are close to records in some cases:

Short term Wednesday through Thursday night
As of 420 am Tuesday...

sfc high pressure prevails across southeast oh and WV through
Thursday.

A low pressure system will move east over the great lakes region
Thursday night. Winds become southwest pumping warm air and moisture
to the area as a cold front approaches.

Long term Friday through Monday
As of 420 am Monday...

a cold front associated with the aforementioned low pressure system
will slowly progress east and south to approach southeast oh by
Sunday morning. Meanwhile, warmer temperatures, abundant moisture
and instability could produce some showers or storms activity
Friday, Saturday and Saturday night.

The front becomes stationary west to east across our area Monday and
Tuesday to continue with chances for showers and thunderstorms.

Aviation 08z Tuesday through Saturday
As of 210 am Tuesday...

brief MVFR is possible with scattered showers along a cold front
crossing the area overnight and Tuesday morning. An MVFR to ifr
fog tail is possible behind these showers overnight into early
Tuesday morning... Coded one up for pkb first couple of hours of
forecast as three hundredths of an inch of rainfall was measured
there.

There does not appear to be much potential for a thunderstorm
on Tuesday given the cold front crossing the mountains by
afternoon.

A CU deck will follow the front Tuesday afternoon up around 6
kft. Tuesday night will be clear and calm as high pressure
crosses. Valley fog may start forming by 06z Wednesday.

Light south to southwest surface flow will switch to light
northwest as the cold front crosses overnight into Tuesday
morning. These northwest winds may be a bit gusty in the
mountains Tuesday afternoon. Surface flow will become calm
Tuesday night, as high pressure crosses. Light west flow aloft
overnight will become light west to northwest Tuesday and remain
so Tuesday night.

Forecast confidence and alternate scenarios through 06z Wednesday...

forecast confidence: high.

Alternate scenarios: brief MVFR to ifr possible with or just
behind sheers overnight into early Tuesday morning. Valley fog
may or may not start forming by 06z Wednesday.

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.
