This is a rather significant area of freezing rain and it is heading directly towards KC early this morning. A line of thunderstorms is on the leading edge, an unusual line of heavy thunderstorms considering it is below freezing this morning. Let’s look at some of the details and your KC weather time-line is posted below.

Here are the graphics I showed last night on the 10 PM news:



A cold surge is arriving this morning, and in combination with an upper level disturbance tracking overhead we are expecting a significant band of freezing rain with a chance of freezing rain thunderstorms to spread up the I-35 corridor. These accumulations I showed last night are possible. I am expecting between 0.10″ and 0.50″ in most areas near KC.  Power outages don’t usually begin until around 1/2″ accumulation happens on the power lines and we will likely fall just short of this potential danger. There is also a chance of sleet before it is over. If it does sleet, then the roads will get covered. If it does not sleet, then most of the roads that are treated will mostly be wet. It will be quite tricky today. Last night we targeted this I-35 corridor to be the center of this system, and it appears to be lining right over this region, which is directly over Kansas City.

Kansas City Weather Time Line:

  • Now through Noon:  Freezing rain spreads over the area and becomes heavy near I-35.  Ice accumulations are likely.  Freezing rain thunderstorms are possible. In these thunderstorms sleet may fall which would coat roads.  Temperatures dropping a couple more degrees into the mid to upper 20s.
  • Noon to 3 PM: The heavy band of freezing rain may change to sleet before ending. The band will slowly shift to the east.  Temperatures in the 20s. Total accumulations of 0.10″ to 0.50″.
  • 3 PM to 6 AM Wednesday:  Temperatures drop a few more degrees, so there will be more freezing of any standing water
  • Wednesday night-Thursday:  Freezing rain and sleet again are likely. Some snowflakes may mix in
  • Friday: There is a chance of rain or freezing rain
  • Saturday: A major winter storm is possible with snow near Kansas City, or just north of the region. We are monitoring this storm closely.

As we showed in yesterdays blog, this part of the pattern is directly related to the first cycle of this years pattern in October. In this first cycle it was rather wet with 5″ of rain in KC. It is an incredible comparison to that first cycle. And, there is some major blocking developing aloft over Greenland. We will discuss this in tomorrows blog and on 41 Action News tonight.

Here is one look at the developing blocking upper high:


That big upper high, the blue H, will have some rather significant influences on the pattern. And, KC may end up with some chances for snow in these next 15 days, not to mention these ice chances.  That is a 575 decameter upper high, which is rather strong. But, it hasn’t formed yet.  This map is valid on March 1st. Let’s see how this evolves.

Please be cautious today and provide a lot of extra time to get around if you have to get out. Thank you for spending a few minutes of your day reading the Action Weather Blog featuring Weather2020 and the cycling weather pattern.  Go to Weather2020 Blog and join in the conversation as we all learn together and share in this weather experience.

    I have a flight at 8:15 Thursday morning. What do you think my chances are of getting out?

      You should go to the weather2020.com blog to ask that. Gary checks those questions more than here. Or there are a great many knowledgeable bloggers who will attempt to answer.
