Area Forecast Discussion
National Weather Service North Platte NE
341 AM CST Sat Feb 24 2018

.SHORT TERM...(Today and tonight)
Issued at 324 AM CST Sat Feb 24 2018

Models in fair agreement early this morning. Banding already setting
up on the radar. Models have indicated mid level forcing last
several days along with 100 to 130kt upper jet at 250mb. Looks to be
a half inch per hour snowfall rates and as dynamics increase and
band sets up could be higher snowfall rates. Have lowered some
snowfall amounts slightly this morning due to faster solutions. Will
remove northwest Nebraska from the advisory this morning and keep
the remainder of the forecast area in winter weather advisory.
Forcing looks to hold this morning and become more diffuse this
afternoon with lower snowfall amounts over north central Nebraska.
Will shorten the advisory with snow ending earlier. Highs today with
partial clearing this afternoon around 30 most areas. Winds to
increase out of the northwest through the morning and spread east
through the afternoon. May move snow some. Tonight clearing skies
with fresh snow cover and have lowered temperatures below
guidance.

.LONG TERM...(Sunday through Friday)
Issued at 324 AM CST Sat Feb 24 2018

West to southwest flow aloft is expected the first half of the
coming week. Milder Pacific air will also filter east into the
region during this time with highs in the 40s. Upper level low
pressure will dig south along the west coast into southern CA by
mid week. This system will turn east and then northeast across
the central portions of the country Wednesday night into
Thursday. System expected to be an open wave with most of the
precipitation remaining east/southeast of our immediate area.

By weeks end a long wave trough will be developing across the
western CONUS. This keeps the flow southwest aloft across our
region with continued mild conditions. Some chance for light
precipitation by next weekend as long wave trough advances east

Issued at 1128 PM CST Fri Feb 23 2018

MVFR and IFR ceilings ranging from 300 to 1500 feet agl are
