Area Forecast Discussion
National Weather Service Omaha/Valley NE
1130 PM CST Tue Dec 5 2017

.SHORT TERM...(Tonight through Friday)
Issued at 312 PM CST Tue Dec 5 2017

A couple of wave moving out of the northern Plains could bring
some light snow or mainly flurries to the area tonight. The first
wave was already spreading flurries through central SD, and this
should continue to roll east southeast down the MO river valley
based on various model suites. Not expecting much accumulation
though so the chance of measurable precip is only 20-30%. This
first wave moves past the area by midnight, but a second wave
could bring additional light snow or flurries 06-12z, in a very
similar area to the first. Snowfall will be very light, but could
accumulate a tenth or two of an inch, and perhaps even up to one
half inch near the SD border.

The second mentioned wave and associated reinforcing cold front
move across the forecast area on Wednesday, and will have a small
chance of snow or flurries as it continues to move south. Temps
will be cooler Wednesday than today. Snowfall through the day
Wednesday probably won`t measure, and could even become raindrops
in the afternoon in southeast NE as surface temps warm into the
upper 30s to lower 40s. Breezy northwest winds increasing to 15 to
25 mph Wed make it feel much cooler.

Dry and cold weather Thursday with highs only 25 t0 30. Temps do
moderate a bit for Friday back into the mid 30s to lower 40s.
Previous forecast of precip for Friday has been pulled out as it
appears models are now trending just east of the area cross the
mid MS River valley.

.LONG TERM...(Friday night through Tuesday)
Issued at 312 PM CST Tue Dec 5 2017

Dry weather at the beginning of the period with temps moderating a
bit back toward normal. Still just below normal on Saturday in the
upper 30s to lower 40s, but should see about a 10 degree rise for
Sunday with decent downsloping flow. A cold front moves into the
are Sunday night, with the next chance for precip coming later on
Monday into Tuesday as an Alberta Clipper settles southward across
the Plains.

Issued at 1130 PM CST Tue Dec 5 2017

cold front had recently moved through the area with second front
over northern plains expected to drop south and into eastern
Nebraska by 18Z. Northwest winds will pick up again after 18Z
behind the front.
