Arctic high pressure drifted overhead this afternoon and provided a frigid day to eastern Kansas and westrn Missouri. Temperatures were in the deep freeze with most areas topping out this afternoon between 10 and 15 degrees. Here is a quick look at regional highs today.
- KCI & St. Joseph 11
- Lee's Summit 14
- Sedalia 15
- Minneapolis, MN -1
- Madison, WI -2
- Green Bay, WI -3
Temperatures were certainly cold today, but nothing record breaking within the viewing area. After our coldest day of the season the focus now shifts to a little warm up for Sunday and Monday...and also a storm.
Let's start with tonight. The combination of clear to partly cloudy skies and light winds will lead to another very cold night. Expect temperatures to bottom out around midnight to 2am somewhere within a couple of degrees either side of zero. Overnight winds will turn to the south-southeast and some clouds will also return to the region. This will keep temperatures from reaching the levels we saw Saturday morning.
The arctic air pushes east Sunday and highs should return to the 20s. Look at the 500mb flow on Sunday afternoon. It switches from the northwest to a more westerly flow. This will keep the really frigid air bottled up for a couple of days.

A piece of energy with the vort max along the West Coast will eject east and head toward the Midwest by Monday. At the surface a warm front will try to push north. The location of the front will be a key to the type of precipitation that occurs across the region. From the 18Z models the NAM is the warmer of the two with the Monday system and would lead to a greater chance of rain or a mix in Kansas City. The GFS is colder, but still keeps temps pretty close to 32. Right now it looks like the best bet for snow would be the same favored areas...north of KC. But keep in mind arctic air will be dropping south again as the moisture arrives. This should help to change over any mix to snow even for Kansas City. But at this moment it is too early to talk snow accumulations since the possible mix or rain line will play a huge role in this next storm. If the NAM has its say...very little snow would fall anywhere. But for the time being here is the 18Z accumulated precip. map for this next storm.

Make sure to watch NBC Action News tonight at 10pm as I will have all the latest 00Z data to pass along. I will answer your questions this evening and then update the blog tomorrow morning. Have a great night...and stay warm!
Don't forget, beginning Saturday, January 26 we are starting a weekend morning newscast! It will air from 8-9am on Saturday and Sunday mornings.
