Heavy Snow Arrives Saturday Night & Sunday

Happy Saturday!

I hope you’re stocked up on whatever you might need to wait out this weekend’s snowstorm.  If not, you still have until early Saturday afternoon.

This is going to short and sweet if you like snow.

Heavy snow is on the way Saturday evening through Sunday evening and some hometowns may have a foot of new snow on the ground by the time it ends late Sunday night or early Monday morning.

A “Winter Storm Warning” has been issued for all of eastern Iowa and northern Illinois from Saturday evening through early Sunday night for heavy snow this weekend and gusty winds, considerable blowing and drifting snow, and falling temperatures Sunday.

A rain and snow mix will begin early Saturday afternoon across our southern hometowns and it will move northward and quickly change over to snow.

Moderate to heavy snow is likely for about a 12-hour period Saturday night into early Sunday.

This is the where the GFS has the storm system at 6 a.m. Sunday.  The darker shades of green show where the moderate to heavy snow will be falling.

Now, let’s talk snow amounts.

The storm has made another shift to the north in the overnight hours, so that means that the heaviest snow will also shift northward out of central Illinois, which was the thinking Friday night.

For simplicity’s sake, 6-12″ of snow are possible with this storm from Saturday evening through late Sunday night or early Monday morning!

Weekend Snowstorm 13115

In the Quad Cities, I’m expecting around 10″ of snow.

Right along Interstate 80 and to the north, that’s where the heaviest snow will fall.  Amounts of 8-12″ are likely.

If you live south of I-80, you’re still going to be heavy snow.  Amounts of 6-10″ will fall there.

Remember that with any snow event, there could be isolated higher totals in any of these ranges.

LAST TIME WE SAW THIS MUCH

If we pick up more than 8.3″ of snow in the Quad Cities from this storm, it’ll be the biggest storm since that much fell back on February 26 and 27, 2013.

And, it was four years ago today (on the calendar) that a three-day snowstorm started in the Quad Cities that would bring 18.4″ of snow to the area, tying a 1979 snowstorm for the biggest snow event in Quad Cities history.

Groundhog Blizzard of 2011

In that 2011 storm, 14.8″ of that 18.4″ total fell on February 1st alone.

BOTTOM LINE…

This is a dangerous situation unfolding with heavy snow, strong winds Sunday approaching 40 miles-per-hour, and considerable blowing and drifting snow.

Additionally, by Monday morning, temperatures will be near zero and wind chills will be much colder.  Monday’s highs will only be in the teens.

Since all of the pieces of the puzzle are in place, this is my only post today — unless something drastic and unforeseen happens.

Be safe and have a great weekend!

P.S.  I’d like to thank my friends at the National Weather Service offices for the “Winter Storm Warning” base maps. 🙂
