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
cape.

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 (06z TAF issuance)
updated at 1220 am est Wed dec 12 2018
vfr expected through the valid TAF period. A modest wsw low-level
jet will develop toward daybreak, and while the speeds aren't too
impressive at 35 kt the directional shear is worthy of llws at bwg
and hnb. By the time this jet translates as far east as sdf, let
alone lex, it should be late enough in the morning to start mixing
out.

Sw winds will increase late in the morning with sustained 15 kt and
prevailing gusts at 20-25 kt for most of the afternoon. Look for the
gusts to lay down around sunset.

Increasing moisture will develop a lower strato-cu deck, which will
be enough for a ceiling by late afternoon early evening. Will keep
itVFR, but just barely so.

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.
