Area Forecast Discussion
National Weather Service Paducah KY
250 AM CST Tue Mar 7 2017

.SHORT TERM...(Today through Thursday night)
Issued at 250 AM CST Tue Mar 7 2017

Will be canceling the TOR watch shortly. Band of convection will
continue to move from west to east across the area early this
morning. Should be out of the area by this afternoon with
clearing skies on tap. Dry weather will be the rule tonight
through Wednesday night with weak high pressure in control. A
boundary will settle south into the area Thursday. Increasing
moisture Thursday night with the presence of the front may yield
showers and isolated thunderstorms. Used a model blend across the
board for temps and weather. HRRR/RAPTL for short term trends.

.LONG TERM...(Friday through Monday)
Issued at 250 AM CST Tue Mar 7 2017

Cool northwesterly flow aloft will dominate the weather picture
through most of the extended forecast period.

The only exception is a brief overrunning type situation early in
the weekend. Most medium range model indications are that a pcpn
shield will develop over the entire PAH forecast area starting late
Fri night, with a probable switch from rain to snow for mainly the
northern half of the region both Fri night and Sat night as the
atmospheric column diurnally cools. Currently, up to an inch of snow
is possible early Sat morning north of I-64, with only a few tenths
to a dusting south of there. As ground and pavement temperatures are
quite warm at this time, this will be mainly on grassy and elevated
surfaces, with little to no impact expected.

Pcpn could end as all snow in the eastern Pennyrile region late Sat
night as colder air sweeps into the region on northerly surface
winds behind the mid level shortwave trof axis. The best (all
liquid) QPF during this event will be Sat afternoon...around a third
of an inch of rain at most locations.

Sat/Sat night should be the coldest of the extended forecast period,
with highs in the 40s and lows mostly below freezing. This should be
followed by a slow warming trend and a return to warmer southerly
low level flow by Mon, with highs in the 50s. Another pcpn event
appears possible just beyond Day 7 (Mon). Especially beyond the
weekend, confidence in the current extended forecast scenario is not
high because of recent inconsistency in the model solutions.

.AVIATION...
Issued at 1120 PM CST Mon Mar 6 2017

Main challenge with the 06z TAF continues to be non convective
winds and timing of main convective line of thunderstorms. Kept
non-thunderstorm wind gusts in the 30-40 kt range but they could
be even higher at times, ahead of the passage of the convective
line. Will keep wind shear outside of the main convective line as
well. Main convective line will pass through during the overnight
hours with rapidly improving conditions during the morning. Could
see strong wind gusts within the convective line as well. Winds
shift behind the line during the early morning hours to NW and
become less gusty.
