...Updated Short Term...

.SHORT TERM...(This afternoon through Sunday)
Issued at 1200 PM CST Sat Nov 18 2017

Strong shortwave exiting eastward through Kansas at midday, with
strong subsidence and drying across SW KS. Pressure gradient has
supported NW wind gusts as high as 50 mph this morning. NW winds
will rapidly weaken after 3 pm, as incoming surface high pressure
settles over SW KS by sunset. Even with full sunshine this
afternoon, 850 mb temperatures will only support lower to mid 50s.

Tonight...Clear and seasonably cold. Surface high pressure will
strengthen further to near 1030 mb as it sinks southward into
west Texas tonight. A light SW wind of 10 mph or less will
prevail. Strong radiational cooling in a dry airmass will easily
allow for temperatures to fall into the mid 20s at sunrise Sunday,
but the weak downslope component should keep most locations out of
the teens.

Sunday...Sunny, windy and warmer. Surface high moves to near the
Arklatex by 6 pm, allowing return flow to establish quickly.
Pressure gradient will support an average windy day for SW KS,
with SW winds averaging 20-30 mph. A modest warming at 850 mb to
near 8C and good downslope components (along with full sun and dry
ground) will allow for most locations to reach the lower to
perhaps mid 60s. Increasing cirrus is expected by afternoon which
will cap temperatures to some extent.

.LONG TERM...(Sunday through Friday)
Issued at 218 AM CST Sat Nov 18 2017

Mean upper level troughing will persist over the Great Lakes
and eastern United States for the next week to ten days, with
upper level ridging over the West. This will result in dry
conditions across western Kansas with occasional cold fronts
as shortwave troughs move from Canada into the northern plains
and upper Midwest. One front will pass through Tuesday morning
and another by Saturday. A warming trend will commence Sunday and
Monday ahead of the next front, and then a little cooler on
Tuesday. Another slight warming trend can be expected Wednesday
through Friday ahead of the next cold front Saturday.

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1100 AM CST Sat Nov 18 2017

Strong shortwave is exiting eastward through central Kansas as of
17z, with strong subsidence, drying and clearing in its wake.
Expect VFR/SKC through this entire TAF package. Very strong NW
winds at midday (peak gust of 43 kts observed at DDC) will rapidly
weaken after 21z Sat, as 1025 mb surface high moves to near LBL
by 00z Sun. Light SW winds less than 8 kts will prevail overnight.
After 15z Sunday, surface high will be located in central Texas,
and return flow will commence with SW winds averaging 15-25 kts.
