Forecast update
Issued at 1101 am est Wed dec 12 2018
mid-level cloudiness is pushing a little quicker to the east this
morning. This should result in a time period of sunny skies
developing in areas along and west of i-65 over the next few hours.

This clearing will eventually work its way into portions of east-
central ky this afternoon.

Temps have responded nicely to the Sun out west with readings in the
upper 40s to around 50. We expect temps to rise in the i-65
corridor over the next few hours and eventually into central ky
later this afternoon. Given the anticipated sun, have bumped up
temperatures for the afternoon period. The Sun will also lead to
some deeper level mixing, so wind gusts of over 20 mph will be seen
this afternoon.

Short term (today and tonight)
issued at 305 am est Wed dec 12 2018
generally quiet weather will continue today under shortwave ridging
aloft. A northern stream disturbance over the upper midwest will
push into the great lakes, and the warm advection regime will
provide fairly extensive cirrus or cirrostratus. Mainly a temp
forecast today which will hinge on the battle between warm advection
and cloud cover. Should run a coupe degrees warmer today than
Tuesday, but still short of the too-warm GFS mos guidance. Sfc
gradient will tighten in the afternoon, kicking winds up to a solid
15 mph with some gusts approaching 30 mph.

Deep upper low digging into the panhandle region tonight will start
to amplify the pattern, with gulf moisture feeding through a deeper
layer. Warm conveyor belt remains well to our south and west, but a
warm advection wing will support a slight chance for some light rain
toward Thu morning, mainly near the ky tn border. With plenty of
cloud cover to inhibit radiational cooling, would not expect mins to
get much below 40.

Long term (Thursday through Tuesday)
issued at 315 am est Wed dec 12 2018
Thursday - Saturday night
a deep trough with a closed off low will be stretched south to the
hill country of texas. The front of the trough will shoot north and
turn east through the ohio river valley. Out ahead of this upper
low, a deep surface low will be centered near dallas, texas. With
tight gradients, stiff southerly wind will carry gulf moisture north
in the low levels while advecting warm air north up the mississippi
river valley. As this system moves east through Thursday, south
central kentucky will see warmer temperatures and increases for rain
showers as moisture continues to wrap around the large low system.

Friday morning, the system will likely become more stacked centered
over southern louisiana as it begins to turn northeast towards
eastern tennessee. As the low passes south of central kentucky,
Friday night could see a few strikes of lightning and hear some
thunder generally south of the bluegrass parkway. Not expecting
anything severe or of concern at this time. The chance of any
thunder is low. There will be low level shear with the low near the
area, but soundings show the area will likely stay capped with weak

By Saturday night, the system will likely be near virginia and north
carolina and will quickly carry its moisture out of the cwa.

Sunday - Wednesday
expect mostly sunny skies. Highs will range from the upper 40s to
near 50, and lows every night will drop to around freezing. The
global models are starting to agree better on where they want to
carry this week's system, as well as general flow into the first
part of next week.

Aviation (12z TAF issuance)
updated at 640 am est Wed dec 12 2018
vfr forecast for most of the valid TAF period, with wind and
potentially shear as the main challenges. Low-level jet isn't quite
as strong or as veered as previously advertised, and since it was
marginal to begin with, we won't mention in this issuance. Still
expect some bumpy approaches with or without mixing. South winds
will increase and veer SW by mid-morning as the boundary layer
deepens. Also look for gradual lowering and thickening of clouds to
a mid-level ceiling, and even as strato-cu comes into the picture
late this afternoon expect it to remainVFR.

Sw wind gusts in the 20-25 kt range this afternoon will lay down
around sunset. Strato-cu ceiling will remain just barelyVFR for
most of the night. Chances of a build-down to MVFR are only great
enough to mention at hnb, though not out of the question in the
other terminals.

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.
