.SHORT TERM...(Tonight through Wednesday)
Issued at 219 PM CST Sun Feb 10 2019

Wintry mix returning to the area late tonight. Stout WAA/295 K
isentropic upglide expands northward out of KS and into the CWA 
and induces precip sometime toward the morning rush tomorrow. 
Soundings are showing lack of feeder-seeder mechanism generally 
through the morning hours with freezing drizzle the dominate 
precip type. By afternoon likely that we will see mix of freezing 
rain and snow. Monday night southern flank vort max associated 
with deep upper trof/strong omega within moist dendritic 
zone/favorable 850 mb temps will aid in dumping most snowfall 
over Monona/Harrison/Shelby counties in IA and 
Thurston/Burt/Washington counties in NE with amounts ranging from 
3-5" possible. Elsewhere over the CWA 1-3 inches possible by  
early Tuesday morning. 

Because of potential ice accumulation have decided to include 
lowest southern tier of counties in the advisory.

Highs on Monday generally in the upper 20s/lower 30s...Tuesday 
mid 20s/mid 30s...Wednesday upper 20s/mid 30s.

.LONG TERM...(Wednesday night through Sunday)
Issued at 219 PM CST Sun Feb 10 2019

Pacific NW wave drops into the central Rockies Thursday afternoon 
and deepens as it crosses the central Plains Thursday evening. The 
latest runs indicates general agreement with track of surface low in 
the vicinity of the KS/OK border before reaching the southern 
Great Lakes Friday afternoon. At this is point it appears that 
the bulk of snow accumulations will occur Friday night. Too far 
out though to try and pin down amounts. 

Cold conditions over most of the CWA on Thursday with below normal 
highs generally in the lower/mid 20s north of I-80, and mid 
30s/lower 40s south of I-80. Friday through Sunday, entire CWA 
bitterly cold with highs topping out only in the mid teens/lower 
20s.
