December Outlook

sioux falls, sd

Winter doesn't officially start until December 21, but it feels like it's already here.

More snow is in the forecast for later this week, followed by a touch of cold weather into early next week. After that, temperatures will slowly start to warm.

The pattern going into the second week of the month is similar to what we saw in October.  It's called an Omega Blocking pattern. It will be dry in the central U.S. with storms on the east and west coast. The difference this time around is that the low pressure in the northeast will move farther northwest toward the Hudson Bay. This should supply hits of colder weather in KELOLAND and the upper plains, eventually breaking down the blocking pattern. If that happens, we'll have a better chance of snow. 

Most years, we see around seven inches in December; in eastern KELOLAND it looks like we could see above average snow.  Average highs are in the 20s to near 30 degrees with overnight lows in the single digits.  We could see above average temperatures a few times this month, but I predict most days will be colder than average.
