AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
126 PM CDT Mon Sep 15 2014

.SHORT TERM...(Tonight through Wednesday night)
Issued at 116 PM CDT MON SEP 15 2014

Radar shows light shower activity to our north, associated with
the front, and to our south, associated with some warm air
advection that occurred ahead of the front. The front will move in
this evening, and thru the FA tonight. The HRR has been perhaps
the best model of the short term pcpn, particularly this morning,
but all more or less shrivel up the frontal precip as it moves
south and into our area. We`ll still maintain a 20 pop fa-wide,
and the northeast could see a few percentage points higher, but
we`ll monitor that in the near term and made adjustments
accordingly.

After fropa, drier air wedges in and down the column tmrw,
particularly late tmrw-tmrw night. This occurs as surface high
pressure works in and across the Ohio valley. By Wed., the high
has shifted east and some return flow warm air advection on its
backside introduces a small/slgt chance mention pops in the
Ozarks. This has been a fairly consistent signal and given the
extent of precip this morning from a similar signal, we`ll
continue to carry some low pops for Semo to cover it, Wed-Wed
night.

.LONG TERM...(Thursday through Monday)
Issued at 116 PM CDT MON SEP 15 2014

The first half of the long term portion of the forecast will see a
trof to the east and a ridge to the west, with our area becoming
more and more influenced by the ridge to the west. This will
result in rising heights and a subsequent warming of the profile.
Highs in the 70s earlier in the week will rebound to the 80s by
the weekend, and lows will do similarly, moving from the 50s to
the 60s in like manner and timing.

Dry weather is forecast into the first half of the weekend, but as
the surface high moves east, return flow kicks in ahead of a
developing frontal system. Jet energy spilling across the High
Plains will lower heights and help drive cylcogenesis and an
eventual front into and through our area, with fairly consistent
member signalling for pops coming in as early as Sat night, and
fropa Sunday. This should result in a return to 70s/50s by early
next week.

.AVIATION...
Issued at 116 PM CDT MON SEP 15 2014

VFR cigs this pm/evening will gradually yield to MVFR cigs
overnight as a front moves through. There is even a chance for IFR
cigs at times, particularly if a vicinity shower invades the
terminal. Otherwise anticipate southerlys shifting to northerlys
overnight with fropa, and gradual cigs improvement/scattering
tomorrow as high pressure works in the front`s wake/departure.
