.SHORT TERM...(Today and tonight)
Issued at 400 AM CST Wed Dec 13 2017

Satellite imagery shows another shortwave trough moving southeast through
the Dakotas early this morning. This wave is progged to move into the
Ohio Valley by this evening. Surface winds across western Kansas were
gradually increasing and veering to a more westerly direction early
this morning. By sunrise, a cold front should be making its way south
across western Kansas. Winds will increase behind the front with gusts
to 35 mph possible through late morning and early afternoon and then
slowly diminishing through the afternoon hours as the surface pressure
gradient relaxes.

The majority of the model and MOS output continues to support high
temperatures in the upper 50s to mid 60s with the warmest readings
over south central Kansas. Winds fall off rapidly toward sunset.
Another shortwave trough currently topping the western North
American longwave ridge early this morning will be approaching the
western High Plains tonight. Mid and high level cloudiness ahead
of this wave will spread over western Kansas tonight. Temperatures
should fall to around or a near 30 degrees after sunset but
should steady out overnight given the increasing cloudiness.

.LONG TERM...(Thursday through Tuesday)
Issued at 400 AM CST Wed Dec 13 2017

The next shortwave trough will move south along the front range of
the Rockies and adjacent High Plains of Colorado Thursday morning.
Model qpf fields try to develop some light precipitation over far
southwest Kansas during the morning hours. Model soundings show
the atmosphere moistening up through a deep layer but both the GFS
and NAM show the best mid level vertical motion associated with
this wave staying west of the KS/CO border. Have backed off on
Superblend pops but will maintain at least a slight chance for light
snow during the morning hours. Another chunk of shortwave energy will
be diving south through the High Plains Thursday afternoon, bringing
a slight chance for light rain to areas of central Kansas mainly along
the I-70 corridor. Max temperatures from the Superblend for Thursday
are now in the mid 40s which looks good given the expected cloudiness.

Western Kansas will see a few mild and quiet days to round out the
week. By Saturday night, another strong shortwave trough will be dropping
out of the northern Rockies toward the central Plains. This system
will help dislodge an upper low over the Gulf of California back across
Texas and the southern Mississippi Valley by Saturday night and Sunday.
This system will likely be too far southeast to provide any moisture
for the forecast area. There will be a slight chance for rain or snow
across central Kansas as the northern Rockies wave moves through.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1144 PM CST Tue Dec 12 2017

VFR conditions will persist through this forecast period. Winds
will gradually shift to the northwest through the remainder of
tonight and then increase from the northwest to north Wednesday
morning as a cold front pushes through western Kansas. Wind gusts
into the 30-35 knot range will be possible by late morning into
early afternoon before winds slowly subside.

.FIRE WEATHER...
Issued at 400 AM CST Wed Dec 13 2017

A cold front moves through western Kansas this morning with
northerly winds increasing behind the front. Based on latest
temperature/dewpoint progs, humidity levels are expected to drop
into the upper teens to around 20 percent today. Thus, a Red Flag
Warning is not anticipated. However, outdoor burning is strongly
discouraged today and this will be highlighted in the Hazardous
Weather Outlook and on social media.
