Area Forecast Discussion
National Weather Service Paducah KY
322 PM CST Fri Dec 8 2017

.SHORT TERM...(Tonight through Sunday night)
Issued at 245 PM CST Fri Dec 8 2017

High amplitude northwesterly flow will continue through the short
term. A clipper system will dive southeast into the Great Lakes
region tonight and early Saturday. Though most of the precip with
this system is still expected to stay north and east of the
forecast area, we could see a narrow band of very light snow sweep
through our far ne counties in sw IN/far nw KY Saturday morning.
Little if any impacts are expected at this time. Any light precip
will be east of the region by afternoon, and skies should clear at
most locations by late in the day. The cold air will continue to
settle into the region Saturday night, with lows back down in the
teens to near 20.

Sunday will bring a gradual moderation in temperatures as winds
turn more southwesterly and increase in speed during the day. No
precipitation is expected.

.LONG TERM...(Monday through Friday)
Issued at 245 PM CST Fri Dec 8 2017

The warm up will continue into Monday with brisk southwesterly
winds ahead of the next clipper type system that will be
barreling southeast through the Midwest and Great Lakes. Highs
will make it back into the 50s during the day at most locations,
and portions of southeast MO may even flirt with 60 degrees.

The aforementioned clipper will drag another moisture starved cold
front through the region Monday night. The main effect of the
front will be to bring another shot of cold Canadian air into the
region Tuesday and and Wednesday. After highs in the mid 30s to
near 40 Tuesday, readings will once again fall down into the teens
to near 20 Tuesday night.

Another shortwave trof may follow later Wednesday or Wednesday
night. This low could track a bit farther s/w than the previous
ones, so will need to monitor trends for a possible increase in
precip chances at that time. Just too far out at this point to
speculate much more. At this point, the signal seems weak on the
GFS and the ECMWF actually buries the system into the sw U.S.

.AVIATION...
Issued at 245 PM CST Fri Dec 8 2017

Mainly clear skies and light southwest winds are expect tonight.
Another cold front will move in late and possibly bring some high MVFR
cigs into areas east of the MS River late tonight and Saturday
morning. Could even see a touch of light snow over portions of
southwest IN and nw Kentucky. Brisk west to northwest winds with
gusts 20-25 kts will follow the front later Saturday morning and
afternoon.
