Area Forecast Discussion
National Weather Service Louisville KY
312 AM EST Wed Dec 13 2017

.Short Term...(Today through Thursday)
Issued at 255 AM EST Wed Dec 13 2017

Low pressure advancing from Minneapolis to Fort Wayne today and to
New York City by tomorrow morning will drag a cold front through
southern Indiana and central Kentucky this evening. Winds will pick
up as the compact cyclone moves by this afternoon and early evening.
The main bust potential should come from the possibility of clouds
limiting mixing, but right now it looks like we'll have enough sun
to help wind gusts reach advisory criteria, especially west of
Interstate 65. After talking with surrounding offices, will go ahead
and hoist an advisory for this afternoon. The strongest gusts will
occur between noon and 4pm CST.

The front itself should be dry, other than perhaps a few sprinkles
from around Madison to Carlisle, thanks to high pressure blocking
the Gulf and most of the precipitation staying to our north closer
to the low.

Given the strong SSW winds and low dewpoints, lifted MaxT today
several degrees, and still may not have gone warm enough if we get a
good amount of sunshine.

After a breezy night tonight with lows around 30, weak high pressure
building in will provide us with much lighter winds Thursday with
high temperatures only in the mid 30s to around 40.

&&

.Long Term...(Thursday night through Tuesday)
Issued at 309 AM EST Wed Dec 13 2017

The next upper shortwave trough will cross the Great Lakes on Friday
but precipitation will stay confined to our north. The surface
reflection of this system looks relatively weak so we're not
expecting strong surface winds with this one.

A southeast ridge will pump up over the weekend as troughing digs
into the Plains. The trough will grab a vort max over northern
Mexico and sling it northeastward into the Ohio Valley. Surface high
pressure shifting from the Mississippi Delta to the East Coast will
supply Gulf moisture. Precipitation type may be an issue Saturday
night depending on how quickly the precipitation moves in and how
much cool air is in place. Sunday, at any rate, will be all rain as
temperatures warm to around 50.

The new week looks to start on a somewhat drier note as the weekend
system pulls away, but, of course, there is some model disagreement
on that.

Taking another peek ahead towards Christmas... Large scale troughing
digging into the Plains will pull cold air down into much of the
country for several days beginning around the 20th or 21st. The
exception to the cold will be in the southeast U.S. near a
developing downstream upper ridge from Central America to the
western Atlantic. This would put the Ohio Valley in the battleground
between the two air masses roughly during the 23rd-25th time period.
There have been indications of wave crossings around the 23rd and
24th as well.

The EPS and GFS are in fairly good agreement with this general
scenario. CPC forecasts hint at this as well, though they are not as
aggressive with the invasion of the cold Canadian air. The
individual members of the GEFS keep S IN/C KY mostly on the warm,
rainy side of things, but with such a large mass of cold, dense air
just to our northwest it's not out of the question that the leading
edge of the cold air could push farther east than currently
indicated. Something to watch over the coming days.

&&

.Aviation...(06Z TAF Issuance)
Issued at 1209 AM EST Wed Dec 13 2017

Wind speeds have reduced dramatically tonight from earlier in the
evening with all TAF sites now 7 knots or less. Wind will gradually
shift early this morning from westerly to southwesterly. The main
issue through the day today will be gusty winds as a low pressure
system approaches and the pressure gradient tightens over the area.
Sustained wind speeds will increase through the morning to 15-20
knots by mid day to early afternoon. Wind gusts will peak this
afternoon in the 25-30 knot range. Winds will shift once again after
0Z to westerly as a cold front moves through the area.

Mostly clear to partly cloudy skies will prevail through much of the
day. Cloud cover will increase tonight as the cold front approaches
and moves though.
