We first told you about how it would be an active, and interesting week to week and a half ahead back on Sunday. We continue to watch every model run come in, and so far, things are looking VERY interesting. Right now, there are still many uncertainties with the forecast, so nothing is set in stone. Things will continue to be changing over the coming days, but what the models are trying to show, is a progressive downward temperature trend with multiple chances of precipitation.
We will first start off talking about the first of many systems that will be working through the state and the upper Midwest over the next week. A clipper system will be moving through the state Wednesday night into Thursday morning. This system is only going to impact the northeast corner of the state. Places like Mason City, Waterloo, Dubuque and places to the northeast will see precipitation. Temperatures will potentially be cold enough Wednesday nigh across the northeast corner of the state that snow may mix in with the rain.
Colder air will then build into the state behind this clipper system, and this will only allow our highs to be in the 40’s on Thursday. Clouds will then be moving out of the state by Thursday afternoon. We will get a brief break before our next system arrives Friday night into Saturday. Highs on Friday will warm up into the lower 50s across southwest Iowa as warm air advection begins to pull in some warmer temperatures, but across northeast Iowa, temperatures will remain in the lower 40’s. Once again, the best chance of precipitation Friday night into Saturday will be across northeast Iowa, and like before, some snow may mix in with the rain as temperatures will be cool enough.
We will get another break on Saturday. After another reenforcing shot of cold air Friday night, temperatures on Saturday will only be in the upper 30’s across the north to the mid to lower 40’s across the south. Most of Saturday will be cloudy, but we will begin to push the clouds out of the state by Saturday evening ahead of our next weather maker, which looks to be the most interesting out of all the systems.
A weather system that will move through the state on Monday has a lot of our attention. This system still has a lot of question marks though as the models differ from one another. Right now the models are showing a system that will move though the upper Midwest, bringing in cold temperatures and potentially snow. The best potential for snowfall depending on how this system sets up will be across northern Iowa. Even if we don’t see the snow, the temperatures will be worth talking about. Highs next week, will potentially only be in the 30’s and 40’s with overnight lows in the teens to 20’s! Talk about a major cool down! This is demonstrated in the very latest 6-10 day temperature outlook as shown above.
Because of all the uncertainties with the system on Monday, we will continue to watch it so continue to check back here for all of the very latest details.
