A few clipper systems will pass through this week with each one bringing a quick hitting of precipitation and gusty winds so read on for the details…
A cold front will slide through the state today fueling a risk for gusty northwesterly winds around level 1-2 on my wind scale across western Iowa. The strong gusty winds will subside later this evening but a second round will hit Wednesday statewide. In addition to the wind, flurries and sprinkles will be possible across northern Iowa later tonight through Wednesday evening before the system presses to the east. Then by Wednesday night temperatures will crash back into the teens and 20s across the state. The overall trend is mild temperatures this week with cooler temperatures northeast due to snowpack.
The second clipper system will arrive later Thursday night and extend into much of Friday. This will start with strong northwesterly winds on Friday and maybe even light rain to the west and light snow to the east. We need to fine tune the precipitation risk but overall should be a nuisance event. The wind risk for the next 2 days is below.
