Here’s a quick update for Sunday and Monday’s snow event.
A “Winter Storm Watch” goes into effect Sunday evening through Monday evening for the counties shaded in blue. This includes the Quad Cities. It’s basically for counties along and north of Interstate 80.
A “Winter Storm Watch” means that conditions are favorable and confidence is building for significant snow accumulation. This is the time to prepare.
It’s usually the case that this “Watch” will become a “Winter Storm Warning”, a “Winter Weather Advisory”, or a “Snow Advisory” before the snow starts to fall tomorrow.
The latest data Saturday evening is coming in snowier, so I’ve upped the snow totals for some hometowns, especially across the north.
I’ll have another update Sunday morning.
Enjoy the rest of your weekend.

“Mother Nature” definitely makes life interesting.
After the second warmest February on record in the Quad Cities with six straight days of record highs of 69°-74° and two tornado outbreaks in Iowa and Illinois in the past two weeks, “Snow Miser” blasts back into area later Sunday into Monday.
A clipper system will drop through the Midwest Sunday afternoon and Monday bringing moderate snow to the area.
It’s likely the Quad Cities will see more snow with this system than what accumulated in January and February combined! (We only picked up 2.7″ of snow in Moline, Illinois, and 2.6″ in Davenport, Iowa, so far, in 2017!)
Parts of Iowa are already under a “Winter Storm Watch” for Sunday afternoon through Monday evening. I expect watches and advisories to cover eastern Iowa and northern Illinois before the snow event begins.
This forecast is based on Saturday morning data and I’ll continue to update this throughout the weekend, as needed.
Snow will break out across eastern Iowa later Sunday afternoon. That snow will likely reach the Quad Cities by midnight.
This is the forecast map for 6 a.m. Monday. Notice the tightly packed lines around the low-pressure system. That means it’ll be windy, so we’ll have to deal with blowing snow, too.
Snow becomes lighter later Monday as it spreads south and east across Illinois.
The snow event ends Monday night even though a few stray flurries are still possible Tuesday morning.
Here are the snowfall amounts I’m forecasting. Keep in mind that these numbers could shift north or south this weekend as newer information comes in. I’ll adjust my forecast accordingly.
So, just find your hometown and that’s how much snow you’ll have to shovel. The kids may finally get to build a “snowperson” and go sledding after a boring winter without much snow!
The good news is that the first half of the weekend will be quiet to give you a chance to get your errands done!
I hope the stores stocked up for the run on milk, eggs, bread, and toilet paper! (I guess “Bumble” can’t be trusted with fragile eggs!)
Finally, while I don’t believe in the fairy tale of “Punxsutawney Phil”, the Pennsylvania groundhog that predicted six more weeks of winter, some people do (I’m looking at you, James!)
When the snow starts flying later Sunday, it’ll have been 5 weeks and 3 days since “Phil” saw his shadow and made his snowy forecast — just inside the “six more weeks of winter” window! 🙂
