...Updated short and long term section...

.SHORT TERM...(Today and tonight)

An upper level shortwave currently over the area will continue to
move eastward towards the Mid Mississippi Valley today bringing
severe weather to eastern Kansas and eastern Oklahoma. Meanwhile, a
second upper level shortwave is progged to move into the Central
Rockies today then into the Central High Plains tonight. Towards the
surface, an area of low pressure will shift from western Kansas this
morning and stretch from central Oklahoma to Missouri this
afternoon. Cold air will be advected southward behind this low
bringing windy conditions and below normal temperatures to western
Kansas. North winds of 30 to 40 mph will be observed this afternoon
with gusts up to 50 mph. High today are expected to range from
around 50 degrees across west central Kansas where the surge of cold
air will move through this morning to around 70 degrees across south
central Kansas where the surge of cold air is not expected to move
through until later in the day. Precipitation chances will also be
on the increase as the day progresses as mid level moisture wraps
around the aforementioned area of low pressure. The chance of rain
showers start out across west central Kansas this morning spreading
across the remainder of the CWA by this evening. Otherwise expect
mostly cloudy skies throughout the day.

Precipitation chances continue this evening as the second shortwave
moves into the Central High Plains. A band of mid level
frontogenesis forms across portions of southwest Kansas overnight
and this is where the heaviest precipitation is expected. Rain will
mix or change over to snow from west to east as the night progresses
with a majority of the CWA changing over to snow by sunrise Monday.
The only exception to this will be across south central Kansas where
temperatures may stay above freezing. With the exception of central
and South Central Kansas, snow fall amounts by Monday afternoon are
forecasted to be around an inch with closer to two inches of snow
possible across the KS/CO border. Lows Sunday night are expected to
range from the upper 20s across the KS/CO border to around 32
degrees across south central Kansas.

.LONG TERM...(Monday through Saturday)

A widespread hard freeze is expected early Tuesday morning as ideal
radiational cooling will likely set up with clear skies and light
winds. Given the fairly high confidence in temperatures reaching the
mid to upper 20s, we will have a Hard Freeze Watch (forecast lows of
28 or colder during the growing season, which has just started
across much of the area) in effect for all of our west central,
southwest, and south central KS counties.

The next weather maker expected to impact the western Kansas region
will be Wednesday Night into Thursday. There are some significant
differences, though, between the ECMWF and the GFS models regarding
degree of amplification and resulting lower-mid tropospheric
development. The GFS is far more aggressive with both the cold air
intrusion into western Kansas as well as precipitation in the cold
sector. In fact, the GFS is suggesting a fair amount of snow in the
cold sector across much of the western half of Kansas Thursday,
whereas the ECMWF shows much less precipitation and focused farther
north toward the Kansas-Nebraska border. The official forecast calls
for Chance POPs (30 to 50 percent south to north) focused during the
day Thursday.  We kept the mention of snow mainly across areas
along/north of the Arkansas River and west of a Jetmore-Hays line,
however if the ECMWF model starts to trend more toward the more
aggressive GFS solution, then this forecast will need to be revised
to include more snow for more areas (as well as much cooler


.AVIATION...(For the 06Z TAFS through 06Z Sunday night)

VFR conditions will prevail overnight with increasing mid level
clouds. Low level moisture will increase towards sunrise with MVFR
conditions expected in the late morning into the afternoon. There
will be a chance of precipitation in the afternoon but have left
the mention of it out of the taf at this time. Winds will
generally be from the north around 10 knots increasing to 10 to 15
knots by sunrise. Stronger winds around 25 knots with gusts around
35 knots are then expected this afternoon.
