.SYNOPSIS...
ISSUED AT 344 PM CDT WED APR 2 2014

The 12z upper air analysis continues to show strong southwesterly
flow aloft from southern California through the central High Plains
into the Great Lakes region. A deep shortwave trough was located
over the Plateau Region with a 110 knot upper level jet in the base
of the trough. A baroclinic zone at 700 millibars was over the
central High Plains from southern Colorado across northern Kansas.
At the surface, a warm front extended from a low pressure center
over southeast Colorado across far southwest Kansas into extreme
northern Oklahoma. A dryline extended south from the warm front
across western Oklahoma into west Texas.

&&

.SHORT TERM...(This evening through Thursday)
ISSUED AT 344 PM CDT WED APR 2 2014

A weak shortwave ripple that was ejecting out of the base of the
upper trough over southern California will be moving out over the
southern Plains this evening. Satellite imagery was showing a line
of moderate cumulus over northwest Oklahoma that was slowly lifting
north. Short term mesoscale models are tending to keep convection to
the south and east of Medicine Lodge late this afternoon.  There is
some potential for a thunderstorms to develop over and north of the
front in south central Kansas this evening given the elevated
instability and the weak shortwave so will continue the slight
chance pops there.

Later this evening and tonight the surface low over southeast
Colorado is progged to move east into Kansas with cold air advection
increasing across west central and southwest Kansas overnight. There
will be small chances for light rain, or more likely drizzle,
developing later tonight.

The main upper trough will be moving out fairly rapidly across the
central High Plains on Thursday. An area of mid level deformation
with the shortwave trough will move out across west/northwest Kansas
during the late morning and afternoon hours. There should be a
fairly well defined band of precipitation associated with the upper
wave. Surface temperatures/dewpoints are progged to remain in the
mid/upper 30s across west central Kansas. Model soundings show
temperatures dropping below freezing not too far off the surface.
Think that there will at least be a rain/snow mix or brief
changeover to snow with the heaviest precipitation tomorrow
afternoon. Snowfall accumulations should remain light as rapid
melting will occur given the warm soil temperatures. The
precipitation should be winding down fairly quickly later in the
afternoon as the upper wave moves east.

.LONG TERM...(Thursday night through Wednesday)
ISSUED AT 339 PM CDT WED APR 2 2014

An active pattern continues in the medium range forecast period as
amplified troughing advances across the Rockies into the High Plains
once again this weekend. Initially, Friday night will likely be
cloudy with an increasing cool boundary layer through cold
advection and precipitation associated with the first exiting wave.
The primarily rain precipitation type will be rain due to a
sufficiently deep melting layer. Wet bulbing may become even more
likely by evening however as the precipitation comes to an end
especially north across interstate 70. The ending of the
precipitation should be followed by a fairly cold overnight at least
in the western sections of the area. Models indicate large
uncertainty farther east into south central Kansas where some
solutions are as warm as the low 40s in line the the high end of the
ensemble members.

Low and mid level (albeit weak) moisture return will redevelop
Saturday as the next upper wave approaches this time perhaps more
likely the southern High Plains region. The GFS and ECMWF were in
good agreement on a system during the weekend however not in very
good phase for timing and mesoscale placement. However the system
appears mainly warm enough for rain precipitation type if with
convective element depending on location. Thunderstorm might be more
possible with a farther north track of the wave where as a farther
southern track will support the main area of instability to be focused
in the panhandles and se Colorado.

Following the weekend wave, deep northwest flow will develop across
the front range and high Plains regions, resulting in windy
conditions probably both Monday and Tuesday. This should also
result in a warming trend into mid week due to relatively dry
downslope winds.

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
ISSUED AT 635 PM CDT WED APR 2 2014

Much of southwest Kansas will be north of the quasistationary
front tonight as a surface low tracks along the Kansas-Oklahoma
border. We expect widespread IFR and lower flight category a
couple hours after sunset with the best chance at prolonged LIFR
conditions at DDC closer to the rich Gulf of Mexico moisture.
Areas of drizzle will likely develop as well, and a few showers
and thunderstorms may affect HYS. Winds will shift to the north
between 06-09Z and increase slightly to around 17 or 18 knots with
higher gusts. Areas of rain and wet snow will likely develop
during the day Thursday, but much of this will likely stay west of
the GCK and HYS terminals.

.FIRE WEATHER...
ISSUED AT 344 PM CDT WED APR 2 2014

The warm front will continue to lift northward through far southwest
Kansas late this afternoon. With Red Flag conditions developing
rapidly south of the front, will keep current Red Flag Warning in
effect until expiration time.
