After a relatively quiet stretch of weather for much of Iowa, a significant pattern of winter storms will affect the over the next 96 hours. There are advisories and watches out, each for a different threat. If you look at the graphic to the right you can see a Winter Weather Advisory for counties highlighted in blue. The first storm system to affect Iowa will strike late tonight and through the day on Monday. This storm has the potential to produce 2”-5” of snow over portions of northern Iowa.
Now some of these counties will drop the Winter Weather Advisory on Monday, other will see it continue all the way into Wednesday. That’s because a second storm system is on the way. As a result a Winter Storm Watch is posted for areas highlighted in green. This area, although missing out on much of the snow set to fall on Monday, could face a stronger storm system passing just to our south Tuesday and Wednesday.
During that time frame, 5”-9” could fall over areas currently under the Winter Storm Watch. The heaviest totals at this time are expected to fall in far southern Iowa. With these storms in tandem, significant snow fall is possible over the entire state this week. That fresh blanket of snow will bring an end to our near or above freezing temperatures for a while. Highs will drop down into the teens with lows dipping below zero at times later this week.
We’ll continue to monitor any pattern changes as these storms draw closer and bring you updates when it’s pertinent.
