Short term (tonight through Monday night)
issued at 245 pm est Sun nov 19 2017
it's been a chilly day with a noticeable westerly breeze as well.

Winds have been fairly steady at 10-15 mph, with gusts to 20-25 mph.

Temps this afternoon were in the upper 30s to low 40s, though we
have a few sites creeping into the mid 40s in the southwest (where
it's been sunny for a while). Stratus clouds still blanket the
eastern part of ky, with the clearing line now east of i-65. The i-
75 corridor will see clouds scatter out by mid-evening. The pressure
gradient relaxes this evening as surface high pressure builds
northeast from texas, so the winds will diminish to 5-10 mph.

That surface high builds across the tennessee valley overnight, so
low-level winds will be light with clear skies. This will allow
temps to drop into the mid 20s Monday morning. Bundle up! Southerly
flow develops on Monday, with deeper southwest flow aloft providing
warm air advection. Expect plenty of sunshine, with highs in the low
50s.

Fair weather will continue Monday night. It'll be quite a bit warmer
than tonight, however. As a storm system moves east across southern
canada, near lake superior, a 35-40 kt southwest LLJ is forecast to
develop over the ohio valley. This will help keep lows in the mid to
upper 30s.

Long term (Tuesday through Sunday)
issued at 315 pm est Sun nov 19 2017
an upper trough digs southeast toward the ohio valley on Tuesday,
sending a cold front through central kentucky and southern indiana
Tuesday evening. Prior to fropa, expect a mild and breezy day with
quite a bit of sunshine. Highs should reach the mid to upper 50s,
and may approach 60 in spots. Decided to maintain the dry forecast
Tuesday evening. The latest suite of model guidance keeps precip to
our north across indiana and ohio, closer to the parent low and
deeper moisture.

We will likely see an increase in cloud cover late Tuesday, with
another shot of cold air arriving Tuesday night. Expect lows to dip
back into the upper 20s low 30s.

The weather continues to look pretty quiet through the rest of the
holiday week. For those traveling on Wednesday, expect fair weather
with chilly temps. After starting out below freezing, afternoon
highs should reach the low to mid 40s. Wednesday night into the
morning of thanksgiving looks cold, with lows in the 20s. Highs on
thanksgiving should recover into the mid upper 40s. We should see
some moderation in temperatures heading into black Friday, with
morning lows around freezing and highs in the 50s.

Medium range guidance is still mainly dry with a cold frontal
passage on Saturday, with a storm track well to our north (similar
to the Tuesday-Tuesday night system). Highs are shaping up to be in
the 50s, with a larger north-south gradient.

Aviation (06z TAF issuance)
issued at 1141 pm est Sun nov 19 2017
cirrus will be our only cloud type as high pressure slides from the
tennessee valley to the carolina coast. Light and variable winds
will become southerly near 10 knots during the day today as that
high moves by.

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 L-36.com 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.
