AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
319 PM CDT Tue Mar 11 2014

...Updated for short term discussion...

.SHORT TERM...(This evening through Wednesday)
ISSUED AT 316 PM CDT TUE MAR 11 2014

A strong upper level system will pass across western Kansas this
evening. Just ahead of this feature, a mid level baroclinic zone
will develop, and there will be just enough mid level moisture
and lift to help generate some light precipitation, mainly along
interstate 70. Rain can be expected at the onset as a nearly dry
adiatic layer will extend 2000 ft below the freezing level.
However, continued cold advection and wet bulbing will cool the
boundary layer enough for snow to reach the ground near or after 00z.
Some accumulation of snow is possible, but due to the brevity of the
event, amounts should remain less than an inch at Hays and Wakeeney.
Due to the high winds, measuring this snow will be difficult at
best. A high wind warning is still in effect for much of western
Kansas, with a wind advisory further east.

Temperatures will drop into the mid 20s to near 30 degrees by
Wednesday morning. In the wake of the upper level system, Wednesday
will still be breezy, with mostly sunny skies and highs in the lower
50s.

.LONG TERM...(Wednesday night through Tuesday)
ISSUED AT 309 PM CDT TUE MAR 11 2014

A relatively active spring-like pattern is in store with frequent
frontal passages through the extended (days 3-7) period, which will
result in temperature fluctuations and chances for rain or snow by
the weekend. Thursday will bring warm dry and breezy if not
borderline windy conditions as mixing ensues by late morning and
early afternoon. Warmer temperatures will be achieved largely to
downslope winds with warmest temperatures approaching 70 degrees
perhaps focused farther north across west central Kansas counties
where the 850 mb thermal ridge will be. Temperatures elsewhere should
be at least 65 degrees and up by the afternoon. Temperatures
overnight Thursday and Friday morning will be influenced by a
relatively warm boundary layer to begin with, clear skies and at
least some mixing near the surface, which could result in mild lows
barely falling into the upper 30s in the far west.

Once the dry frontal passage occurs, temperatures will likely
moderate slightly upward again on Saturday back into the 60s, with yet
another surface frontal boundary affecting the area Saturday night
or early Sunday. A shortwave digging into the southern High Plains
is indicated will bring an upper deformation zone across the area
with potential for a weakly organized band of rain and rain or snow
depending on the thermal profiles realized. The remainder of the
period heading into Monday appears continued slightly normal or
near normal conditions with highs the 60s and lows in the 30s.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
ISSUED AT 1242 PM CDT TUE MAR 11 2014

A strong upper level system will pass across western Kansas this
afternoon and evening. Strong north winds at 30-40kts will persist
though 03z in the wake of surface low pressure, before subsiding.
Blowing dust could restrict visbys to 4sm through 23z at GCK/DDC.
Some light rain or snow is likely at KHYS between 23 and 04z as
the upper level trough axis approaches, and this could restrict
visibilities to MVFR. MVFR CIGS can be expected after 22-23z at
HYS/GCK/DDC, before clearing develops after 4z in the wake of the
upper level system.
