Area Forecast Discussion
National Weather Service Springfield MO
323 PM CST Wed Dec 7 2016

.SHORT TERM...(This evening through Friday)
Issued at 320 PM CST Wed Dec 7 2016

An upper level low is currently located over the Great Lakes
region this afternoon. An upper level trough and cold front is
current pushing across the Plains. Dry air in the low levels has
kept much of the area dry this afternoon, except for east central
Kansas into west central Missouri where a band of snow was able to
develop, with lingering light snow farther to the north. This band
of snow will sag south and gradually weaken. This band of snow was able
to overcome the dry air and get snow to the surface. The snow will
likely dissipate and not see much snow in the way of snow flakes
south of I44. The snow should dissipate by mid to late evening.
Moderate to brief heavy snow will be possible within this band.
The band of snow will not stay over any given locations too long.

The heaviest snow amounts will be across eastern Kansas into
western Missouri where a dusting up to an inch of snow will occur
on mainly elevated and grassy surfaces. Farther to the south a
dusting to maybe a half inch will be possible closer to I44.

Behind the front a very cold air mass will slam into the area.
Lows will drop into the upper teens to the lower 20s tonight with
highs not warming out of the 20s on Thursday. Lows Thursday night
will drop well into the teens with single digits likely for some
of the colder sites as the cold air mass and high pressure will be
over the area. Wind chills in the single digits can be expected
during the morning and overnight hours Thursday and Friday.

.LONG TERM...(Friday Night through Wednesday)
Issued at 320 PM CST Wed Dec 7 2016

Southerly winds will return on Saturday and will be on the breezy
side. Highs this weekend will warm into the 40s. Another system
will then track through the area later this weekend and will bring
some rain to the area, and possibly light snow on the back side.
At this time little if any accumulations are expected. There is some
uncertainty with this system as there are differences with medium
range models from run to run and from each other.

Another shot of cold air may then spread into the area during the
middle to end of next week as another system sweeps through the
region. At this time moisture will be limited and not much in the
way of precipitation is expected.


.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1057 AM CST Wed Dec 7 2016

Radar has been showing some snowy echoes across the area, however
dry low levels have prevent this from reaching the ground until
around 16z. Starting to get some flurries developing over extreme
southeast Kansas and west central MO now and it should start
working its way into the SGF/JLN areas this afternoon. Ceilings
will continue to lower and may see some MVFR visibility when it
begins to snow. Clearing should take place by late evening with a
clear sky for the overnight hours.
