Good morning! Winter storm warnings and advisories are out for Iowa for expected snowfall on Wednesday:
Simulated radar going from tonight through Wednesday evening: Showers move into Nebraska this evening through the overnight, then we see a transition to heavy, wet snow in northeast Nebraska during the pre-dawn hours, then expected a thump of heavy, wet snow in north-central Iowa Wednesday morning, continuing into the afternoon:
Here is a map of our thinking regarding the risk of snow accumulations. We do think a band of 3-6″ is likely across northern Iowa, with isolated higher totals expected.
Total precipitation from tonight through Wednesday evening:
The next threat for precipitation arrives Friday through the weekend, but this threat will be focused across the western and southern Plains. High pressure centered over the Great Lakes looks to keep Iowa mainly dry for the upcoming weekend. Here is the forecast radar off the European model from 1am Friday to 1pm Sunday CDT.
European model has been trending lower with precipitation amounts, but still brings up to a half-inch in southwest Nebraska. The GFS (not shown) still puts down 1″. I think the European has a better handle on late week rainfall. At least we aren’t talking about snow chances. 🙂 Again, trends suggest that Iowa misses out on this system.
We also work in a gradual warming trend from the weekend through next week across the entire area. Here is the temperature forecast off the European EPS for Des Moines, Iowa over the next 15 days:
North Platte, Nebraska (temps likely underdone at times next week):
High temperatures over the next 4 days:
Low temperatures over the next 4 days:
Wind forecast over the next 4 days:
Weeks 1 and 2 temperatures from normal. Warmer times finally arrive for week 2.
Weeks 1 and 2 precipitation from normal:
