.SHORT TERM...(today through Saturday)
Issued at 310 AM CST Thu Jan 19 2017

Low clouds working slowly north at 08Z from western and central
Kansas into central Nebraska in advance of 850mb trough over
western Nebraska. 500 mb closed low was also in the area centered
over south central Nebraska.

Cloudy skies are expected to gradually overspread the forecast
area today as upper low moves toward northeast Kansas with short
range models showing some slight deepening during this time.
Temperatures remain above freezing across the area early this
morning and are expected to climb into the 40s by afternoon. Will
only mention patchy fog for a time this morning and mainly in

stratus. Temperatures will likely have a more limited diurnal
range in areas where clouds arrive first this morning. Have also
removed mention of drizzle for today as low level moisture comes
in slower than indicated by previous days models.

Periods of drizzle and fog become more likely tonight into Friday as
the upper system works north across the area with lingering low
level moisture in advance of the next wave moving into the area on
Friday. With better moisture and forcing associated with this
second system rain chances increase Friday night then decrease
from south to north on Saturday as the system lifts into the upper
midwest. Temperatures again are expected to remain above freezing
Friday night keeping precipitation all liquid.

expected to return to the region on Tuesday and Wednesday. There
will be a chance of snow for northeast Nebraska on Tuesday with
rain changing to snow in southeast Nebraska and southwest Iowa by
Tuesday afternoon or evening extending into Tuesday night. Snow
