South Dakota North Dakota border. Significantly colder north of
the warm front with temperatures in the 30s at 18z across North

This colder air is forecast to begin to spread south on Monday
behind a cold front which models bring into eastern Nebraska by
late afternoon before stalling out across the area through Monday
night. Better forcing and moisture look to remain mainly north of
the area on Monday as the front approaches but some sprinkles here
and there not out of the question late Monday afternoon into the
evening. A better chance of showers moves into the area late
Monday night and becomes likely on Tuesday and Tuesday night as
the stalled frontal boundary begins to become more active and push
southeast into Kansas and Missouri with overrunning pattern
developing north of the front as strong upper trough approaches
the central plains. Parts of northeast Nebraska could see a mix of
rain and snow for a time late Tuesday night and Wednesday morning
before ending.

Temperatures will be turning colder behind the front on Tuesday
with north winds increasing to 10 to 20 mph and gusty. Northern
parts of the area are expected to remain in the 40s on Tuesday and
again Wednesday. The clouds and rain will hinder any freezing
temperatures or frost Wednesday morning but pockets of freezing
temperatures are possible Thursday morning in northern and western

.LONG TERM...(Wednesday night through Sunday)
Issued at 245 PM CDT Sun Apr 23 2017

Pattern looks to remain cool and wet through much of the period
beyond Wednesday night as a series of upper troughs track across
the central plains. Most significant system currently indicated by
models will impact much of the region over the weekend with
widespread showers and thunderstorms. Some potential for snow is
also indicated for parts of the western high plains region during
this time.


.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1222 PM CDT Sun Apr 23 2017

VFR conditions are expected through the period with only scattered
high level clouds. As a low-level jet develops over the area
tonight we will see low-level wind shear develop at all 3 TAF
sites. This will likely continue into mid morning on Monday before
the low-level jet weakens and the boundary layer couples with
southwest winds increasing with gusts likely from the southwest.
