508 AM MST Sat Feb 10 2018
.SHORT TERM...(Today and tonight)
Issued at 329 AM MST Sat Feb 10 2018
A winter weather advisory is in effect from this morning through
Sunday morning.
An upper trough swings through the Central Rockies and Central
High Plains between mid day today and mid day on Sunday as cold
surface high pressure pushes further south into the Southern
Plains.
Current expectations are for very cold temperatures to remain
across the area today and tonight. Precipitation will remain as
all snow across the forecast area with areas of very light snow to
continue through this morning with stronger areas of development
extending eastward out of Colorado into far southwest Nebraska and
northwest Kansas by mid day as the area of best lift associated
with the upper trough begins to transition the area. As the upper
trough sweeps across the area roughly from west northwest to east
southeast, expect the favored area of precipitation to continue to
stretch eastward across the forecast area as the entire pattern
transitions further south during the evening before dissipating
Sunday morning. As a result, highest snowfall amounts should be
seen from west to east across the central portion of the forecast
area with somewhat lower amounts across the far northern and
southern sections. Highest amounts of snow will approach 4 inches
while widespread 2 to 3 inches is expected elsewhere.
Winds should remain under 10mph through Sunday, so there really
isn't any blowing and drifting expected with the snowfall.
Fresh snow and skies that will begin to clear tonight will produce
low temperatures in the single digits above zero. Wind chills of 5
to 10 below zero will be common. Wind chills are not as low as
previously forecast, but could end up being colder if skies clear
out more rapidly, or there is an increase in expected wind
speeds. With those uncertainties, the previously issued Winter
Weather Advisory was left intact with the same timing to account
for the snowfall expected along with the potential for lower wind
chills early Sunday morning.
With the colder surface high pressure moving further east over
the plains and a weak lee surface trough developing ahead of the
next upper low pressure area deepening over the western U.S.
by monday night, expect highs to warm mainly into the 30s on
Sunday and into 40s across mainly the southern half of the
forecast area by Monday.
.LONG TERM...(Tuesday through Friday)
Issued at 212 AM MST Sat Feb 10 2018
Tuesday and Wednesday: The ECMWF and GFS are in good agreement as we
head into Tuesday. Split flow to our west will prevail as a closed
low remains in place just off the southern California coast. H5 high
pressure over the Gulf of Mexico will keep southwesterly flow aloft
in place both days across the southern and central Plains. This high
pressure will elongate and spread westward as we head into
Wednesday. This will serve to nudge the area of low pressure
westward and shift the flow aloft more westerly over the CWA. Dry
weather is expected both days with highs near average on Tuesday.
Highs on Wednesday will be well above average with highs in the
upper 50s to lower 60s.
Thursday through Saturday: Upper flow remains westerly Thursday and
Friday with a subtle lee trough forming to our west late Thursday
afternoon. Should see some amplification at the H7 level as we head
into Friday with this trough, allowing a mention of slight chance
PoPs during the afternoon/evening. The low that was off the southern
California coast will be pushing inland at this time. Model
solutions vary greatly with the GFS opening it into a wave much
sooner than the less progressive ECMWF. This system will influence
the region late Saturday; however, the strength of the system is in
question and model agreement is too weak at this point do portray
any confidence regarding potential impacts.

VFR conditions will transition quickly through MVFR to
occasionally IFR by 18Z at GLD and 19Z at MCK as light snow begins
to spread across the region. IFR with intermittent MVFR conditions
