Area Forecast Discussion
National Weather Service Goodland KS
305 PM MST Thu Dec 14 2017

.SHORT TERM...(This evening through Friday)
Issued at 207 PM MST Thu Dec 14 2017

Currently instability snow showers are moving across the area. As
we approach sunset, this precipitation will rapidly end. Otherwise,
winds will drop off dramatically near and shortly after sunset. A
further decrease and shift to the west is expected by late
evening. This combined with decreasing cloud cover and dewpoints
will allow low temperatures to drop near or slightly below
guidance.

Flow aloft tomorrow will shift to the northwest. Models are showing
a decent amount of mid and upper level cloud cover. This will offset
the increasing 850 mb temperatures and downslope winds or would go
even warmer than what I have in there. Still temperatures will range
from the middle 50s to the lower 60s.

.LONG TERM...(Friday night through Thursday)
Issued at 305 PM MST Thu Dec 14 2017

The synoptic pattern over the CONUS has been characterized by
ridging aloft along the Pacific coast/Intermountain West,
troughing aloft along/east of the MS river, and NW/NNW flow aloft
over the High Plains and Front Range of the Rockies for some time
now, but not for much longer.

A rather chaotic transition is expected over the CONUS Sat-Wed as
the synoptic pattern undergoes an effective reversal, with
pronounced troughing aloft over the Intermountain West/Rockies
and pronounced ridging aloft along the SE coast expected by the
end of next week. A fair amount of uncertainty is present w/regard
to the forecast this weekend through early-mid next week. At this
time, no significant weather is anticipated over the High Plains
through the middle of next week. However, long range guidance is
in good agreement w/regard to a reversal in the synoptic pattern by
late next week. Thus, an increasing potential for significant
weather (characterized by below normal temperatures and above
normal chances for precipitation) appears likely to develop late
next week into next weekend.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1032 AM MST Thu Dec 14 2017

Vfr conditions are expected through the period. Northwest winds
will be near 22 knots with gusts to near 30 knots through sunset.
At that time, the gusts will stop as the sustained speeds decrease
into the 10 to 15 knot range. By late in the evening the winds
will shift to the southwest at 7 to 12 knots. These winds will
continue through the end of the period.
