Dangerously cold wind chills will be impacting the state next week, and so will more snow. Tonight light snow will be moving through the state, only bringing 1 to 2 inches of accumulation. Winds will be the bigger story gusting up to 40mph at times leading to reduced visibilities. After this less then impressive system moves through the state this evening, high pressure will be moving into the state Sunday night. Highs on Sunday will be in the single digits with wind chills ranging form -15° to -25°.
Highs on Monday will be a few degrees warmer, however, another system will be knocking on the door. A clipper system will be moving across the northern part of the state, which could bring moderate snowfall accumulations. Snowfall accumulations of 6″ may be possible across northeast Iowa. This is why a winter storm watch has been issued for Monday afternoon into Monday evening. The highest threat area lies south of a Rochester Minnesota to Boscobel Wisconsin line. There will likely be significant travel impacts for some Monday night into Tuesday morning.
After this system clears out, another area of high pressure will move into the state on Tuesday. This will bring another reinforcing shot of cold weather. Waking up Wednesday morning, wind chill values will range from -25° to -40°. Some areas of northern Iowa may need a wind chill warning issued due to the dangerously cold wind chills. Temperatures will then be improving by the end of next week.
Continue to check back here for all of the latest details as we will continue to keep an eye on tonight’s system and the one that will move through Monday night into Tuesday.
