Area Forecast Discussion
National Weather Service Dodge City KS
215 PM CST Tue Feb 21 2017

...Updated Long Term...

.SHORT TERM...(This afternoon through Wednesday)
Issued at 1151 AM CST Tue Feb 21 2017

Splendid spring weather continues, in February. A clear sky will
continue this afternoon, with temperatures approaching record
levels in the mid to upper 70s. SW downslope winds of 10-20 mph at
midday will weaken by sunset.

Tonight...Increasing mid/high clouds and a light downslope SW
wind of 5-15 mph will work together to keep temperatures again
unseasonably mild for February. Expecting all locations to remain
above freezing, ranging from mid 30s NW to mid 40s SE.

Wednesday...Continued unseasonably warm, with 70s for all zones
during the afternoon, near 80 along the Oklahoma border. Per GFS
soundings, introduced a period of mid/high overcast for several
hours during the morning. Winds will be variable in direction,
starting out SW in the morning, light and variable during the
afternoon, then increasing from the SE late in the day in response
to lee cyclogenesis in eastern Colorado.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 215 PM CST Tue Feb 21 2017

Dry weather will prevail across SW Kansas. The only exception to
this is a possible period of rain or wet snow across the far NE
counties Thursday evening. With dry weather persisting, that only
leaves winds, temperature swings and fire weather concerns for
impacts.

Thursday...Strong shortwave over southern Utah at 6 am will race
into western Kansas by 6 pm. As a result, strong cyclogenesis is
expected across SW KS during the afternoon hours (12z ECMWF
depicts 988 mb surface low near Kinsley around 4 pm). Exactly
where this surface low tracks Thursday will have an impact on
temperatures, wind fields, and where the fire danger will be
highest. Along with WFOs AMA/OUN, increased winds south and SW of
Dodge City, where gusts near 40 mph are likely from Elkhart to
Liberal. Critical fire conditions are likely across far SW zones,
potentially extremely critical along the Oklahoma border.
A healthy temperature gradient is expected, ranging from near 60
north to near 80 south. An increase in clouds for a time Thursday
morning, followed by clearing behind the departing surface
cyclone.

Thursday night...12z ECMWF continues to clip Trego/Ellis counties
(I-70 corridor) with wraparound rain and/or wet snow for several
hours Thursday evening. GFS, with its further north cyclone track,
is completely dry across these areas. After coordination with
ICT/GLD/GID, kept the slight chance pops offered by the model
blend. System looks very progressive, which will make meaningful
precipitation across our NE zones difficult to achieve. Primary
impact Thursday night will be strong cold gusty NW winds behind
the cold front.

Friday...Windy and sharply colder. Any wraparound light snow
expected to remain north of SW KS, although stratus may invade the
northern zones. Temperatures actually below normal for a change,
struggling into the low to mid 40s, with wind chills in the 20s
and 30s. Not unusual for late February, but this winter it will be
a shock.

Friday night/Saturday morning...Cold. Models show consistency
with Canadian surface high settling directly over SW KS. A hard
freeze for all, with teens common across the NW CWA.

This weekend...Continued dry with slowly moderating temperatures.
Much warmer temperatures expected again early next week.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1130 AM CST Tue Feb 21 2017

VFR conditions at all locations through the TAF period. A surface
trough located in Eastern Colorado deepens, causing wind from the
south-southwest at 5-15 knots, changing to west-southwest ~12Z,
then to west-northwest by ~18Z as the trough slowly moves east.
Upper level moisture moves in ~12Z for all TAF sites for a short
period, dropping ceilings to roughly 15-20,000 feet.
