Updated aviation discussion...

Short term (today and tonight)
issued at 300 am edt Thu mar 21 2019
a vertically stacked low pressure system centered over lake michigan
will drift southeastward along the longwave trough currently
situated over the eastern u.S. Trailing from the surface low is a
weak cold front that will sweep across southern indiana and central
kentucky today bringing light rain accumulations of up to a quarter
of an inch. Precip should taper off from west to east Thursday
morning and into the afternoon hours for ky counties east of i-75.

Lingering cloud cover throughout the day combined with northwesterly
flow and weak cold air advection will cause temps to be about 10
degrees cooler than yesterday with MAX temps ranging from the upper
40s in southern indiana to the lower 50s for most of central
kentucky.

Models tend to agree on a period of clearing skies late Thursday
night into the early morning hours of Friday. Time heights indicate
lingering low level moisture, which could lead to the development of
fog and or stratus Friday morning. Model soundings show boundary
layer winds strong enough to keep any widespread dense fog at bay,
so will opt for redevelopment of stratus Friday morning. Lows are
expected to drop to the low to mid 30s for Friday morning.

Long term (Friday through Wednesday)
issued at 329 am edt Thu mar 21 2019
Friday through Saturday night:
a weak surface trough will pass through the region from north to
south on Friday behind the main surface low over new england and
upper trough swinging through the saint lawrence valley. There will
be enough low level moisture for scattered clouds, but precipitation
is not expected. Temperatures will lift to around 50 but will be
offset by a chilly northwest breeze gusting to 15-20 mph.

Then canadian high pressure will move from the boundary waters to
chesapeake bay Friday night - Saturday night, keeping us dry.

Temperatures Saturday morning will dip into the mid-upper 20s.

Sunday through Monday night:
surface low pressure near kansas Sunday morning will move into the
ohio valley Monday and then will continue off to the east. Models
differ in the strength of the digging upper trough and the path and
strength of the surface low, but the bottom line is that we'll have
shower chances in the forecast through this period, with the most
widespread activity on Monday. A few rumbles of thunder will be
possible, especially in southern kentucky Monday afternoon. Total
rainfall amounts should be less than an inch.

As for precipitation type, it should be all, or nearly all, rain.

Having said that, incoming cold air will chase outgoing
precipitation Monday night, and lows by Tuesday morning should be in
the lower and middle 30s. Some GEFS members do show the potential of
some light snow as the precipitation ends. Regardless, little if any
impact is expected the way it looks right now. The ECMWF and cmc
show no snow on the ground.

Tuesday through Wednesday:
arctic high pressure will reach the ohio valley by Wednesday. It
will have weakened and modified by the time it arrives, and
thicknesses will be increasing behind the early week system, so
temperatures should be just a few degrees cooler than normal for
late march.

Aviation (12z TAF issuance)
updated at 640 am edt Thu mar 21 2019
current radar shows the band of light rain now extending ne-sw
across central kentucky ahead of a weak cold front. Behind this is
an area of light rain showers associated with the upper low. MVFR
cigs expected throughout much of the day, though satellite does show
intermittent breaks in the clouds. Lex will hold onto rain chances
until later this afternoon. Winds will increase from the northwest
and gusts up to 20kts are possible this afternoon. Expect winds to
decrease by sunset with clouds clearing overnight.

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.
