..update to synopsis...

issued at 845 am CST Thu Dec 14 2017

WV imagery indicates an upper level shortwave trough of low pressure
moving south across The Four Corners region. Meanwhile, a secondary
upper level shortwave trough is dropping southward across the northern
plains. Near the surface, an area of high pressure is sinking southward
across eastern Colorado.


Short term...(today and tonight)
issued at 338 am CST Thu Dec 14 2017

A mid level shortwave will be moving southeast across Colorado this
morning, as surface high pressure intensifies across the central and
southern High Plains. The GFS and NAM have been showing a broken
lower tropospheric frontogenetic zone NW to se across se Colorado
into SW Kansas. This may produce light precipitation showers across
our far south western counties, in the form of snow or a snow/rain
mix. The rap/hrrr solutions appears more dry near the surface than
the other models, favoring flurries/sprinkles at best. With such
expansive cloudiness across the area, temperatures may struggle to
fall to the freezing point, remaining in the low 30s most areas.
Temperatures will respond well to insolation despite the cloud
cover, as the GFS MOS jumps 10 degrees by noon, however, respectable
850 mb cold temperature advection becomes established areas-wide in
the early afternoon, limiting temperatures to the low to mid 40s
across all of central and SW Kansas.

Long term...(friday through wednesday)
issued at 338 am CST Thu Dec 14 2017

The upper trough will shift to the deep Southern Plains on Friday,
bringing back a quick return to southwest flow across our area.
Surface winds will probably be in the 10 to 15 mph range, adding
gusts in the afternoon, however not strong enough downslope or warm
enough source air to warm highs any higher than the 50s. Guidance is
marginally warmer on Saturday before the next cold front shifts
through the area, knocking highs back down into the 40s for Sunday,
and close to climate normals with lows expected in the 20s. The
remainder of the week continues to bring the dry pattern with highs
generally in the 50s and low in the 20s.


Aviation...(for the 12z tafs through 12z Friday morning)
issued at 500 am CST Thu Dec 14 2017

A shortwave trough approaching in the northwest flow aloft will generate a
midlayer overcast at the airports today, averaging 5-7k ft above ground level per
forecast soundings. VFR cigs/vis will continue. After 15z, northwest winds
will increase to an average of 15-25 kts at ddc, a few knots weaker
at hys and a few knots stronger at gck/lbl. Shortwave will pass
around the 00-03z Fri timeframe, followed by rapid clearing to sky clear
and a diminishing northwest wind.


Fire weather...
issued at 338 am CST Thu Dec 14 2017

Sufficiently warmer temperatures Friday and Saturday will lend to
lowered minimum afternoon relative humidities with breezy
afternoons, and elevated fire weather conditions.
