...WINTER STORM WARNINGS CONTINUE FOR THE SIERRA MADRE AND SNOWY
RANGES TILL 11 AM TODAY...

.UPDATE...
Issued at 443 AM MST Thu Mar 7 2019

With snow ending across the NE Panhandle and WY High Plains, went
ahead in canceling the winter weather headlines across this
region. The Winter Storm Warnings for the Sierra Madre and Snowy
Ranges are still in effect until 11 AM this morning.

&&

.SHORT TERM...(Today and Friday)
Issued at 411 AM MST Thu Mar 7 2019

Diminishing light snow showers and lingering areas of
fog/freezing fog will continue through much of the remainder of
the morning. Much of the snow accumulating bands have departed our
region into central and eastern Nebraska along with areas across
western South Dakota. Will likely let the current winter weather
headlines to run their course and expire at their respective times
considering the lingering travel impacts due to slick roadways and
limited visibilities.

Models are still depicting some potential for light snow showers
in the western portion of the forecast due to availability of
low-level moisture coupled with low amounts of instability.
Otherwise with upper level riding building into the region,
conditions will turn dry and temperatures remaining near seasonal
averages. Areas of blowing snow that may impact travel will
generally be isolated to the southern portion of Carbon County in
the Snowy and Sierra Madre Ranges extending up towards the
Interstate 80 corridor. Strong gap winds from Elk Mountain to
Arlington certainly possible. Wind gusts generally west of the
Laramie Range gusting into the 30 to upper 40 mph range.

Our next weather system will impact the region mainly Friday
afternoon through Saturday. The EURO and the GFS have trended the
center of the low into the southeast corner of CO. Implications
that have shifted some of the heavier snow totals out of our
region. The Sierra Madre and Snowy Ranges could again see up to
another fresh foot of snow. Otherwise looking at two to four
inches of new accumulation along the SD border mainly from Lusk
to Chadron. Most locations should see at least some accumulating
snow but looking at generally under an inch.

Temperatures will generally be cooler and near to above freezing
across the northern NE Panhandle with upper 30s and low 40s near
and along the Laramie Range and southwest NE Panhandle.

.LONG TERM...(Saturday through Wednesday)
Issued at 411 AM MST Thu Mar 7 2019

Saturday will see the continuation of the low pressure system and
snowfall ending during the late morning hours. Concern this period
along with the snow will be for increased strong, gusty winds
across the region. Models are in strong agreement in these winds
across much of the high plains in both states and the wind prone
along Interstate 80. With fresh snowfall and wind gusts in excess
of 35 mph, certainly not out of the question to start thinking of
blowing/drifting snow coupled with slick roadways and limited
visibility impacting the area.

A quiet turnaround with the system passing eastward on Sunday
through Tuesday with upper level riding building in albeit
short-lived. This ridge will quickly move off for our next system
to build off the Rockies. Uncertainty still remains on the track
the system will take as it exits the Rockies. The GFS being quite
bullish in tracking the system through NE meaning greater chance
for precipitation and accumulation while the EURO keeps the center
low south in OK leaving us mainly dry with potential for some
gusty winds. Will have to keep monitoring the later model
solutions to determine the ideal track this system will make and
if any weather impacts for the area.

.AVIATION...(For the 18Z TAFS through 18Z Friday morning)

VFR expected over the southeast Wyoming terminals through the period

this afternoon but may return later tonight over that area.

.FIRE WEATHER...
Issued at 411 AM MST Thu Mar 7 2019

With cool temperatures, recent snowfall and precipitation
potential over the next several days, do not anticipate any fire
weather concerns.
