Area Forecast Discussion
National Weather Service Wichita KS
1158 AM CST Mon Dec 5 2016

.SHORT TERM...(Today through Wednesday night)
Issued at 153 AM CST Mon Dec 5 2016

A shortwave trough was lifting northeast out of N. Mexico spreading
widespread rain across S. Texas and points downstream across the
Lower Mississippi Valley area and much of the Southeastern U.S.
while another shortwave trough was moving eastward across the
Northern Rockies.

As the mid lvl flow increases over the Central Rockies today, the
pressure gradient will tighten resulting in breezy southerly winds
returning to central KS helping to drive temperatures into the 50s.
The northern stream shortwave trough will drive a cold front south
across the region tonight with H85 CAA driving temperatures down.
Highs on Tuesday will struggle to reach 40 across central KS while
highs climb into the low 40s near the OK state line. Another
progressive shortwave trough is progged to move out of the Central
Great Basin area and into the Central Rockies late Tuesday night
spreading light snow downstream across the Central Plains States and
into central KS mainly after 08-10z. Recent trends have supported a
northward shift of the deeper isothermal layer and more favorable
snow growth zone lowering confidence for accumulating snow across
southern KS on Wednesday. Generally trended accumulations and pops
down near the OK state line and maintained a 2-3 inch accumulation
swath along the I-70 corridor. The progressive nature of the
shortwave trough appears to be the biggest limiting factor for
higher accumulations with only a narrow 3-5 hour window for
accumulating snow. A Winter Weather Advisory for snow may still be
needed, especially across our central KS counties.

Drier, subsident air will arrive Wednesday night with continued low
level cold air advection driving lows into the single digits across
much of central KS while teens will be common over southeast KS.

.LONG TERM...(Thursday through Sunday)
Issued at 153 AM CST Mon Dec 5 2016

Surface high pressure will settle over the Central Plains on
Thursday-Thursday night allowing strong radiational cooling and
single digit lows across most of the area. Highs will struggle to
reach 20 over portions of central KS while highs rise into the
upper 20s near the OK state line. Low level southerly flow will
return on Friday-Saturday with moderating temperatures and dry
weather conditions. Maintained low pops on Sunday with a
progressive zonal flow but confidence in measurable precipitation
remains low at this time.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1149 AM CST Mon Dec 5 2016

Surface pressure falls will occur this afternoon across
central/eastern Kansas ahead of an approaching cold front.
Southerly winds gusting to 25-31 knots will affect most terminals,
with lesser wind at the CNU site. South winds will diminish to
light early this evening. The cold front is progged to push
southward through central Kansas mid-late evening, and the ICT and
CNU terminals overnight, with winds shifting to northwesterly
with gusts of 20-25 knots likely for several hours behind the
front. A period of stratus may develop along/southeast of the
Kansas Turnpike toward mid evening, given lighter winds and
lowered dewpoint depressions just ahead of the fropa. This would
impact the ICT and CNU terminals, with improving conditions likely
within a couple of hours behind the cold front passage late
tonight.
