Catching Up To Averages...

We *had* been way behind in our snow season snow totals just a couple of weeks ago pre-December. Fast forward 16 days to December 16th, and we've seen snow 13 of the past 16 days that can be measured to be at least a trace amount. Now we are catching up to the average in Sioux Falls. We are now officially up to 11.3" of snow this snow season thanks to an additional 2.6" we picked up today. That puts us at 1.3" below average now, with the average being 12.6" today.

In Mitchell we've seen 13.7" which puts us 6" above our 7.7" average at this point.

Did we mention that we have more snow on the way already for Thursday? We're going to keep a close eye on this one as well, with the majority of the storm coming from the Southwest. That means it'll give us at least a bit of warming along with the snow. Don't expect to see our frigid weather continue.

Here's what the models are showing so far for Thursday:

Option A)

This model would put eastern South Dakota and southwest Minnesota in the 1-3" range. It is more reasonable that the other option below.

Option B)

This one shows around 2-4" of snow around the area in a 12 hour period. We'll keep you updated as this next system forms - as well as on our next system after this one (Saturday). Have a great rest of your Tuesday!

How is snowfall measured when the wind is blowing as hard as it was this past weekend?

Howdy,

Well, it's hard to really get a truly accurate measurement. When I was in college we actually tested out some ideas to "corral" the snow into a measuring device. After speaking with the National Weather Service in Sioux Falls about how they get snow totals with the wind, here's what they have to say about it: "downwind of a building or sheltered area... and taking several measurements. It's tougher at the airport than in town with buildings."

Hope that answers your questions! Also, send us your snowfall totals when you can measure them yourself! We don't need you to be an official weather observer or anything, just send us what you see!
