Area Forecast Discussion...CORRECTED
National Weather Service Goodland KS
153 AM MST Wed Nov 22 2017

.SHORT TERM...(Today through Friday night)
Issued at 144 AM MST Wed Nov 22 2017

Across the Tri State region this morning...skies are a clear to
partly cloudy mix as a veil of mid/high clouds works SSE off the
central Rockies/northern Plains region. Temperatures are mainly in
the 20s...with a few locales around 30-32F. Winds are mainly light
from the SSW.

For today and on thru Friday night...dry conditions are expected for
the area as H5/H7 ridging remains in place for the western portion
of the country. Models carry a shortwave over the ridge
Friday/Friday night. As this system works thru the Plains
region...the CWA will see a cold front move thru the area.

With the strong ridging in place over the next 72 hours...the area
will see above normal daytime temps. Today the area will see temps
in the be replaced mostly by the 70s for Thursday and
Friday...tempered only by approaching cold front Friday from the NW
as the shortwave works off the central Rockies. For Thursday/
Friday...these numbers will be 25-30 degrees above normal. Records
are possible to be broken in some areas each day. Please refer to
the Climate section below for further info.

Overnight lows will range in the mid 30s to lower 40s tonight and
Thursday night. By Friday night the passage of the cold front will
usher in another round of CAA that will allow for lows to drop to
around 30F.

Other than the wild temperatures swings the area will see over the
next 72 hours...the only other wx concern will be the strong winds
over the area on Friday/Friday evening on the backside of the
exiting cold front. Gusts 30-35 mph are possible.

.LONG TERM...(Saturday through Wednesday)
Issued at 150 AM MST Wed Nov 22 2017

Above normal temperatures and dry conditions are expected this
weekend as upper level ridging continues to dominate the large scale
pattern in the Western US and Central Rockies. Western US ridge is
shown to transition eastward as positively tilted trough digs into
the western US through the weekend into early next week. There are
some model variances on timing of eventual trough passage and it`s
associated front Monday through Monday night which could impact
temps. If front slows down we could see record high temperatures
Monday with strong WAA in deep southwest flow (H85 temps 20-21C).
All guidance continues to show a prohibitively dry air mass in place
and the main forcing associated with this trough splitting around
our CWA. Temperatures should be closer to seasonal normals behind
this trough (next Tuesday and Wednesday).


.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1049 PM MST Tue Nov 21 2017

Throughout the remainder of the TAF period, VFR conditions will
prevail at the McCook and Goodland terminals. Wind directions will
shift quickly throughout the next 24 hours.
