.SHORT TERM...(Today and tonight)
Issued at 345 AM CST Fri Feb 24 2017

Today and Tonight...
The RAP and HRRR models indicate the area of moderate to heavy snow
across the sandhills will decay this morning. The dual pol snow
water equivalent product indicates 1 inch per hour snowfall rates.
The snow forecast leans on those solns and an additional 1 to 2
inches of snowfall is expected between 12z and 18z today. Both
models indicate some light snow redevelopment across Southwest
Nebraska.

All weather highlights remain in place. Ice covered...drifted and
snow covered roads are widespread. Wind gusts to 30+ mph are
indicated through at least 18z this morning which will produce
significant blowing and drifting snow in some areas...mainly east of
highway 83. Winds are expected to decrease this afternoon.

Temperatures today rise into the 20s using blended guidance plus
bias correction. Tonight...precipitable water falls to around 0.10
inches across Western Nebraska and 1025 high pressure will build
across the same area. Some high clouds are indicated in the models
but the very dry air support support lows around zero if not colder
across the central and western Sandhills. This is about 5 degrees
colder than blended guidance.

.LONG TERM...(Saturday through Thursday)
Issued at 345 AM CST Fri Feb 24 2017

Main forecast concern for this period will be the colder than normal
temperatures. Lowered temperatures a few degrees on Saturday across
the northern forecast area where fresh snow pack over 6 inches
should keep temperatures in the upper 20s to low 30s. Temperatures
will remain cool with highs several degrees below normal through
Thursday.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1121 AM CST Fri Feb 24 2017

Northerly winds will continue to wind down this afternoon across
western and north central Nebraska as a powerful upper level low
tracks into Iowa. Ceilings will continue to lift this afternoon at
both the KLBF and KVTN terminals. VFR ceilings are expected this
afternoon into the evening hours with HTS ranging from 12000 to
20000 FT AGl. Skies will gradually scatter out tonight with
CIGS around 20000 FT AGL.
