Area Forecast Discussion
National Weather Service Wichita KS
617 PM CST Sat Jan 20 2018

.SHORT TERM...(This evening through Tuesday night)
Issued at 220 PM CST Sat Jan 20 2018

In the short term, low-level cloud cover that was widespread
across the area this morning and early afternoon has been mixing
out from west to east across the area. Behind the clearing, sunny
skies have been prevailed allowing temperatures to climb into the
upper 50s in central Kansas and low 60s in south central and
southeast Kansas.

Overnight tonight, low level moisture will once again make its way
into central Kansas and along the Flint Hills and could
potentially saturate the air enough to produce some patchy
drizzle. The biggest uncertainty surrounds exactly how low
temperatures are expected to drop to coincide with this low-level
moisture in central KS. ECMWF, SREF, Canadian, and NAM indicate
that areas of patchy freezing drizzle are possible with temps
dropping to the freezing mark or slightly below, while the HRRR
and GFS are less agressive with the push of cold air advection
into the northwest corner of the CWA. Therefore, not ruling out a
few areas of isolated patchy freezing drizzle in Central Kansas
tonight and into early Sunday, but ice accumulations and travel
impacts should be minimal.

The focus of the forecast will then shift to the impressive upper
level trough currently situated over the southwestern U.S. This
system is expected to strengthen and push a surface low over Kansas
through the day on Sunday night into Monday. Though it is expected
to bring some significant winter weather to portions of western
Kansas and Nebraska, a wedge of dry air that will be situated over
much of the forecast area should prevent the bulk of the CWA from
receiving significant impacts from the system while keeping most
snowfall further to our north. With that being said, current
thinking is that areas of central and eastern Kansas could see up to
1-2 inches of snow locally Sunday night-Monday.

Additionally, with a very tight pressure gradient force in the wake
of the shortwave on Monday, northwest winds will be quite high with
gusts up to 45mph possible in central Kansas.

.LONG TERM...(Wednesday through Saturday)
Issued at 220 PM CST Sat Jan 20 2018

Following the frontal passage, an upper level ridge will dominate
the synoptic pattern through much of next week before the next
shortwave begins approaching the region next weekend. Temperatures
are expected to cool back down heading into Monday, though will
be around normal for the time of year with highs in the mid 40s.
Another gradual warming trend will then continue through Friday of
next week.

.AVIATION...(For the 00Z TAFS through 00Z Sunday evening)
Issued at 607 PM CST Sat Jan 20 2018

Aviation concerns will be low clouds and fog.

Water vapor imagery shows potent shortwave tracking across the
desert southwest with surface low pressure continuing to deepen
over eastern CO. As moisture continues to stream north, a
strong stationary front will setup tonight from northeast KS into
sw KS. Surface low will be on the move Sun and will track from the
OK Panhandle into eastern KS by early Sun evening. Low ceilings
are expected as the front slowly sinks south tonight which should
bring some IFR conditions to KRSL-KGBD and possibly KSLN. Not out
of the question to also see some visibilities in the 3-4sm range
with these lower cigs. KCNU may also see some low ceilings
overnight as moisture continues to pump into the region. Areas
west of I-135 will maintain best chance for low ceilings during
the day Sun as colder air continues to spill south behind the
departing low.

.FIRE WEATHER...
Issued at 220 PM CST Sat Jan 20 2018

Very high grassland fire danger is expected across nearly all
portions of central, south central, and southeast Kansas on
Monday. Strong winds out of the north/northeast with sustained
speeds around 35mph and gusts near 45mph are possible. Very high
grassland fire danger will also be present in central and south
central Kansas on Thursday and Friday of next week.
