Area Forecast Discussion
National Weather Service Goodland KS
819 AM MST Mon Jan 22 2018

.UPDATE...
Issued at 818 AM MST Mon Jan 22 2018

The western portions of the Blizzard Warning has been cancelled as
skies are clearing, snow is coming to an end, and winds speeds
decrease through the remainder of the day.

UPDATE Issued at 425 AM MST Mon Jan 22 2018

Update to forecast to extend Blizzard Warning for central
portions of the CWA thru 18z to match up with eastern locales.
Conditions across the area have not abated to warrant canceling
the warning for central zones.

.SHORT TERM...(Today through Wednesday night)
Issued at 229 AM MST Mon Jan 22 2018

Across the Tri State region this morning...blizzard conditions
remain over the area as winter storm continues a slow trudge east.
Currently the system lies over north central Kansas...putting the
CWA on the backside of the system. Northerly winds remain high
ranging from 35 to 55 mph at times. Latest radar loop shows back
edge of heaviest precip now nearing Highway 25.

With the slow trend eastward with all elements of this
storm...have continued Blizzard Warning for all areas thru
forecasted time. However over the next couple hours if
central/western zones do not show conditions abating...will have
to extend timing to match up with eastern areas(17z-18z).

As the day progresses today...do expect winds to taper down but
some locales will see areas of blowing snow thru 00z Tuesday.

For tonight on thru Wednesday night...high pressure over the
region but cold...especially for overnight hrs. With current snow
cover on the ground from this storm...have trimmed back temps for
the entire short term as do not think models have compensated
temps for snow over area.

.LONG TERM...(Thursday through Sunday)
Issued at 229 AM MST Mon Jan 22 2018

For the extended period...mainly dry conditions expected for the
extended period at this time. H5 ridge over the Plains shifts
east on Thursday allowing for upper level trough to shift out of
the northern Rockies and then SE over the central Plains on
Friday. Subsequent model runs have been showing less and less qpf
chances for the northern tier of the CWA...and latest runs now
have this system coming thru dry. The upcoming weekend will have
H5 ridging returning to the Rockies...putting the CWA under NW
flow aloft...allowing for CAA to put temps near to/just below
normal...especially for locales along and north of Interstate 70.

&&

.AVIATION...(For the 12Z TAFS through 12Z Tuesday morning)
Issued at 430 AM MST Mon Jan 22 2018

Blizzard conditions are expected to continue both the McCook and
Goodland terminals. LIFR and VLIFR flight categories are expected
to improve from 15Z onward. Conditions will first improve in
Goodland as the system moves Eastward, followed my McCook around
18Z. After 23Z VFR conditions will return to the area with
Northwest winds at 10-15 knots.
