Update
Issued at 640 pm est Tue dec 18 2018
after sunset, temperatures are starting to quickly drop off.

Loaded in the latest observations for temps and dew points to make
sure the near term forecast reflected the ongoing conditions. Forecast
lows still seem to be in good shape thus far, but will continue to
monitor throughout the evening. Also, given the extensiveness of
the fog in the valleys last night, and similar conditions in place
(high pressure with quickly dropping temps and a strong inversion
expected to develop), went ahead and added valley fog back in for
the overnight. It was a bit drier today than yesterday, so did not
mention any dense fog, though can't rule out a few isolated
instances near water bodies. All updates have been published and
sent to ndfd web. A new forecast package was also sent out to
reflect the addition of valley fog.

Short term (this evening through Wednesday night)
issued at 319 pm est Tue dec 18 2018
high pressure will remain the dominate feature heading into
tonight and tomorrow. Eastern kentucky will remain on the western
side of these ridge axis, keeping us in return flow through
tomorrow. This will keep milder conditions in place again
tomorrow. Lows tonight will fall off into the 20s under mostly
clear skies. Cross over temperatures will be well under freezing
for tonight, suggesting more frost than fog through the overnight
hours. Tomorrow will be milder as the southerly flow continues to
build on the western peripherals of the ridge.

By late tomorrow and tomorrow night, clouds will be on the
increase as a shortwave pushing northward from the gulf of mexico
moves towards the region. A low level jet is expected to develop
with this feature and could aid in allowing precipitation
development into east kentucky by 12z on Thursday. The flow will
be downsloping in our eastern zones, so will stick with a gradient
in pops late Thursday night going from nothing in the east to a
high chance in the southwest. Despite the increasing clouds, cloud
heights will remain relatively high, allowing for the colder
eastern valleys to decouple and cool off well into the 30s.

Temperatures may come up as denser cloud cover arrives by dawn
Thursday.

Long term (Thursday through Tuesday)
issued at 405 pm est Tue dec 18 2018
the extended period will begin as a dynamic system approaches
from the central conus. Through early Saturday, a deep upper level
trough along with a surface low pressure system will track over
the ARKLATEX region, up through the tennessee valley and to the
east of kentucky, then eventually progress up into the northeast.

From Thursday evening through early Friday, model soundings from
the NAM and GFS show pwats at or near one inch. Therefore, a
decent rain will again be in store for eastern kentucky. Storm
total rainfall from Thursday through Saturday is estimated to
range from an inch to about an inch and a half. Model soundings
also show that the dominant precipitation type will be rain
through Friday. However, with temperatures decreasing overnight
Friday into Saturday, a changeover to snow is expected. Little to
no snow accumulation is expected for most areas, but some light
accumulation is possible in the higher terrain along the va
border. Opted to load in raw data for temperatures and winds
Friday since it was more representative of the CAA and tight
pressure gradient leading to higher winds. Also, due to upslope
flow during this time, kept likely to categorical pops for eastern
kentucky into the evening.

High pressure as well as upper level ridging will dominate
through the first part of the new work week. Although, a weak cold
front will progress over the ohio valley late Sunday into Monday.

This will most likely just bring clouds and maintain cool
temperatures into next week. Return flow from high pressure will
then bring a slight chance for some precipitation on Tuesday. With
low temperatures at or below freezing Tuesday morning, there is a
slight chance for some rain snow mix into christmas morning.

However, no snow accumulation expected since the precipitation
will quickly change over to rain as temperatures increase into
mid-morning.

High temperatures will begin above normal then decrease to be at
or near the seasonal norm Friday through the start of next week.

Highs will then increase to around 50 degrees by christmas day.

Lows Friday morning will be in the low 40s, but be much colder
through Monday with temperatures generally in the upper 20s to low
30s. With some clearing during the overnight and light winds, the
valleys will be cooler than the ridgetops in the mornings Sunday
through Tuesday as well.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 641 pm est Tue dec 18 2018
high pressure in control will keepVFR conditions and light winds
throughout the TAF period. Valley fog will likely form once again
tonight, with MVFR to ifr conditions possible. However, do not
expect this fog to reach the TAF sites, so kept out at this time.

High clouds will begin working into the western TAF sites (ksme
and kloz) late in the period tomorrow ahead of our next weather
system..

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
