What forecasters said that day

The local office's own words before this high wind warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Cheyenne, WY wrote its last area forecast discussion before this high wind warning went out at Feb 7, 3:56 AM MST, 4 hours 33 minutes earlier.

Area forecast discussion, Feb 7, 3:56 AM MST, 4 hours 33 minutes before
Area Forecast Discussion
National Weather Service Cheyenne WY
356 AM MST Wed Feb 7 2018

.SHORT TERM...(Today through Thursday night)
Issued at 250 AM MST Wed Feb 7 2018

A slow warming trend will begin today with locally strong winds
across the wind prone areas being the primary forecast concern
through the middle of the week. Arctic front is currently along
the I-25 corridor early this morning with temperatures in the 20's
and teens, with single digits further to the northeast. Snowfall
has ended across the area with low clouds along and east of the
front. Current thinking is this front will move east of the I-25
corridor late this morning before rapidly retreating eastward by
this afternoon. Daytime temperatures will respond with highs
mostly in the 40's. Winds have been behaving across the Wind Prone
areas thus far this morning with gusts between 35 to 40 MPH in
the Arlington and Elk Mountain areas. Do not anticipate any last
minute High Wind headlines into Wednesday morning.

For tonight and Thursday, models show the arctic front close to
the Lusk and Chadron area with the boundary across far northeast
Wyoming and near the Black Hills. Because of this, kept
temperatures north of the Platte River valley below guidance.
Attention then shifts to winds, with models showing an increase in
low to midlevel subsidence late Thursday and Thursday evening with
700mb winds over 50 knots and a 100kt Pacific jet moving into
Wyoming. May need a High Wind Watch soon for at least the
Arlington zone as well as the I-80 summit late Thursday through
Thursday night. Want to see an additional model run before
committing to any watches or warnings since models yesterday were
more aggressive with winds early this morning. Highs on Thursday
will be pleasant and generally in the upper 40's to upper 50's,
warmest across extreme SE Wyoming and the southern NE panhandle.
Winds will spread into the high valleys and high plains on
Thursday, but do not anticipate gusts over 50 MPH at this time.
For Thursday night, all models show the arctic front making
another push southward with snow developing north of a line from
Douglas to Alliance Nebraska by sunrise Friday. Increased POP in
these areas between 30 to 60 percent.

.LONG TERM...(Friday through Tuesday)
Issued at 230 AM MST Wed Feb 7 2018

Arctic boundary forecast to lay just north of the Cheyenne CWFA
Friday morning and it pushes into the area through the late
morning. Going to see light snow break out across the northern
Panhandle and Niobrara County Friday morning and as the front
moves southwest, we should see increasing chances for snow across
a wider area. By Friday afternoon the front should lay along the
laramie Range with 700mb temperatures falling to -11C across the
northern Panhandle and -6C directly behind the front. Temperatures
falling through the day as the front moves in.

Confidence low on snow totals Friday night into Saturday as the
more consistent GFS is now trending towards the ECMWF solution. A
lot less precip for our area, at least initially.

Secondary shortwave set to move across the front Monday with
better chances for widespread snow Monday afternoon into Tuesday.
One thing for certain is it will be cold with 700mb temperatures
-13 to -14C and 850mb temperatures -8 to -10C behind the front.
 Single digit to low teen highs behind the front for Saturday.
 Slow warming for Sunday and Monday. Do think I may be too warm,
 but had to match up with neighboring offices for Monday/Tuesday.
 If we do get that widespread snow Monday/Tuesday, we can drop
 probably 5-10 degrees off going highs.

&&

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 354 AM MST Wed Feb 7 2018

Some lingering low clouds (MVFR to IFR) over the southern
Nebraska Panhandle from Scottsbluff to Sidney should slowly move
off to the south as the early morning progresses. VFR all
locations after 15-16Z. No weather impacts for southeast Wyoming
and northern Nebraska airports today.

&&

.FIRE WEATHER...
Issued at 136 AM MST Wed Feb 7 2018

No Fire Weather concerns through the weekend. Mild temperatures
and drier conditions are expected Wednesday and Thursday as an
arctic cold front retreats east of the region. This front will
return to the area by the end of the week resulting in colder
temperatures and a good chance of accumulating snow Friday and
Saturday.
