725 pm edt Sat aug 17 2019

Disturbances passing north this weekend. Very warm to hot the
first half of next week. Cold front by late in the week.

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

convection mainly remained north of the area, and diminished
quickly this evening. Made some minor edits to the temps, winds,
and sky cover this evening. River valley fog has decreased in
coverage steadily over the last few days with drying, and have
that trend continuing.

As of 130 pm Saturday...

a surface high pressure system currently centered near jackson,
ky will slowly drift east through the period, with weak
southwesterly flow developing tonight into Sunday. This will
bring added low level moisture for Sunday. Today will be mostly
dry with the high pressure system in control. A convective
complex currently over central in should brush by to the nw,
with an isolated t-storm possibly scraping across the far nw
forecast area. High res models are in decent agreement keeping
this activity just outside of the cwa, but its close enough
that low end pops seems warranted.

A weak upper level shortwave trough passes by to the north
overnight, but again the surface high should keep keep activity
to the north of the forecast area. Areas of river valley fog are
expected with flow remaining weak.

With a bit better moisture on Sunday, have isolated to scattered
showers and storms across mainly the mountains. The GFS has more
widespread QPF chances, but think it is too aggressive with mid
level moisture.

Temperatures remain above normal through the forecast period.

Heat indices are expected to be in the upper 90s across the
southwestern forecast area Sunday afternoon.

Short term Sunday night through Tuesday night
As of 215 pm Saturday...

heat wave is prog to continue for at least the first half of the
upcoming work week. H85 temps are prog to warm to approx 22 c
for most of the CWA on Monday and Tuesday, with afternoon sfc
temps likely to warm into the mid 90s across the lower
elevations (few areas could flirt with 100 degrees). Combination
of the high sfc temps along with higher dewpoints could result
in some areas reaching heat advisory thresholds (however dry
soil conditions could result in greater than progged diurnal
mixing... And thus lower heat indices). Convective chances early
next work week are not all that great as lack of significant
moisture depth and very warm mid level temps should preclude
much in the way of convective initiation. Although at least
isolated diurnally driven convection is likely each day given
the very warm temperatures.

Long term Wednesday through Saturday
As of 215 pm Saturday...

Wednesday will likely be another warm and humid day, although a
slow lowering of height fields aloft should allow for slightly
greater convective chances across the region. A cold front is
then prog to push across the CWA sometime Thursday-ish with
additional shower and thunderstorm chances. This front should
help lower temps back to near normal levels by late in the week.

Aviation 23z Saturday through Thursday
As of 725 pm Saturday...

continuing the trend of decreasing coverage and duration of fog
in the river valleys as the area continues to dry out. The only
lifr in the forecast is at ekn. Otherwise, there only brief
periods of ifr fog expected tonight in clear skies and calm

Vfr cumulus field develops again Sunday.

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

forecast confidence: medium to high.

Alternate scenarios: timing and density of fog may vary tonight.

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.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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 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.
