It's a great FRIGID Thursday,
The 0 verses 100 degree question results are in the previous blog! ZERO wins again!
Can you believe how cold it is with complete sunshine? Wow, at noon it is still 8 degrees at KCI Airport. Today's high will likely be only around 12 to 18 degrees. Wow, this is VERY COLD. So, this evening expect a quick drop to near 0 or below again just northeast of Kansas City and into the single digits elsewhere.
There is a chance of snow/sleet showers on Friday morning. Look below at the 700 mb forecast for 6 AM Friday. The moisture (Green shades) indicates it is completely saturated at this level likely resulting in a thick overcast moving across early in the morning. The latest data produces enough lift and squeezes out just a few hundreths of an inch of precipitation, likely in the form of snow. Think about it, let's say just 0.02" falls somewhere on Friday morning around sunrise. This is almost nothing, but it could be a quick 1/2 inch of snow. With the ground being so cold it could cause all kinds of problems. Since this is about as much as this fast moving wave of energy is going to produce it will make it difficult to pin it down until it actually happens. So, we will likely be upping our chance to 50% of the trend continues in this direction. This is for just a 5 to 9 AM window early on Friday.

A big warm up is likely after this goes by on Sunday into Monday. But, this warm up happens at the exact same time that a very cold Arctic air mass builds over the western half of Canada, as you can see in the last blog entry. This Arctic air will ooze into the United States by Tuesday. And, this is the time we expect to go into our stormy part of the LRC. The latest GFS has a series of storm systems beginning to show up and close enough where I now am buying it on the models. Does this sound familiar? A series of storm systems in October, then 54 days later a series of storm systems in December, and then 54 days later a series of storm systems in late January and February.
Look below at the forecast for one week from today. This is a strong winter storm forming. The blue dashed line is the rain/snow line. It is again in our viewing area. We won't go further into our analysis as it is still so far away, but confidence is growing, and this is what we have been expecting, based on my theory.

Bundle up and have a great day! We will have special weather graphics ready for our newscasts tonight on NBC Action News. The first thing we will concentrate on is the chance of any snow on Friday morning, and then we will stress the warm up. I think most of us are ready for at least a little break, aren't we?
