Happy Monday. Talk about gorgeous weather (like we haven’t said that the last few days). Four places in the state hit 80 degrees: Des Moines, Waterloo, Shenandoah, and Red Oak.
Heads up: This post is going to be abbreviated to just the short-term period (tonight through Tuesday night). Information on the upcoming storm later this week will be made in a separate post.
1. Cloudy Night
GOES-16 imagery shows clouds already on the increase across parts of western Iowa. These are mostly high, thin clouds at this point, which aren’t being picked up by any airport sensors out that way quite yet. Winds are relatively calm west of Interstate 35, while picking up to 10-20 MPH with gusts as high as 35. Winds should diminish further tonight with low temperatures falling to the 40s.
2. Warm and Dry
One final day of all-around nice weather. Clouds will be on the increase throughout the day on Tuesday with highs a bit cooler, ranging from the upper 50s north to near 70 south. Precipitation chances increase during the afternoon hours in the north, but the bulk of the rain should hold off until the overnight hours, perhaps closer to Wednesday morning. Thunder/lightning is not expected. While rain has been plotted at all points, the best chances will be north of Interstate 80.
3. Here it Comes….
Here it comes indeed. A Winter Storm Watch is in effect for Lyon county from late Wednesday night to Friday morning. A significant winter storm will impact the region during this period, likely grazing our far northern counties. A separate post will describe this further.
Temperatures struggle to recover behind the storm over the weekend, but 60s should be widespread again by the middle part of next week, likely prompting more flooding concerns with the associated melting.
