Area forecast discussion, Oct 5, 8:39 PM CDT, 1 hour 57 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
839 PM CDT Sat Oct 5 2013

.SHORT TERM...(This Evening through Sunday)
ISSUED AT 824 PM CDT SAT OCT 5 2013

Current analysis is a very complicated pattern this evening. Front
is through West Plains and St. Louis with bands of showers and
thunderstorms ahead and just behind the front. Rainfall is very
efficient and may have isolated flooding issues yet tonight.
Thinking is at this time that it will not be widespread.

Severe potential still exists. 850 jet is expected to increase and
models indicate more storms could develop and move up from the
north. still have surface based instability over west Kentucky and
this may lift farther north into southern Illinois and southwest Indiana.

.LONG TERM...(Tuesday through Saturday) ISSUED AT 243 PM CDT SAT
OCT 5 2013

Models agree on a mainly dry forecast in the extended forecast with
cooler air in place. The latest model runs agree on high pressure at
the surface bisecting the forecast area. In addition they indicate
ridging aloft in conjunction at the surface which would dictate a
dry forecast. Skies will be mainly clear although cant rule out a
few friendly cue in the afternoons. Moisture is very slow to return
to the area mainly due to the light transport winds in the boundary
layer. Even when the winds shift southerly late in the forecast they
still remain light. That is until late in the weekend day
8...another system takes shape over the plains and is poised to move
into the heartland late in the weekend. The GFS is not very stable
from run to run with the timing of this system. However the ecmwf
seems to be steady with the timing over the last two runs.

Below normal temperatures will moderate back to normal as we
approach the middle of the week.
