Synopsis
High pressure remains in control, with cool nights and warm
afternoons through the weekend. A strong cold front and low
pressure system crosses early next week.

Near term through tonight
As of 1024 am Friday...

no changes this morning. Carbon copy of yesterday, so get out an
enjoy the warm afternoon if you are able.

As of 255 am Friday...

surface high pressure moves directly overhead with mostly clear
skies through the period. Temperatures will continue to moderate
and highs will climb a couple degrees warmer than yesterday. With
the high overhead tonight, boundary layer winds will be light,
valley fog will likely be thicker than we saw the last two
nights.

Short term Saturday through Sunday
As of 245 am Friday...

high pressure remains in control through the short term.Used a
consensus blend for highs and lows, with temperatures
continuing to run above normal for late october.

Long term Sunday night through Thursday
As of 245 am Friday...

a cold front will push through Monday night into Tuesday. Models
have some discrepancy on timing of the front, and especially
the track of the low pressure system the front is attached to.

The ECMWF is much farther west, taking the low from western tn,
through in and northwest oh. The GFS on the other hand brings
the low across the forecast area. Either solution should still
result in a good dose of precipitation, so have a fairly broad
area of 80+ pops. Kept some low probability thunder mention in
Monday afternoon just ahead of the cold front.

Cold air filters in as an upper trough slides through Tuesday
night and Wednesday. Should enough moisture linger behind the
surface feature, we could see some snow flakes at high
elevations. A brief ridge dries things out to end the work week.

Aviation 15z Friday through Tuesday
As of 630 am Friday...

high pressure overhead today with mostly clear skies. Low level
flow will be much weaker tonight through Saturday morning, so
ifr valley fog will be possible. Higher confidence for ifr fog
early Saturday morning at crw and ekn, so have added with the
12z TAF issuance. May have to expand fog coverage as forecast
becomes more clear later today or this evening.

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

forecast confidence: high today and medium overnight.

Alternate scenarios: ifr fog development tonight will vary from
current 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.
