Is That Cold Air I See Building Up?

Good morning bloggers,

Anticipation of the signs of winter weather is growing as we move through this month. Kansas City averages about 1″ of snow during the month of November.  The largest snowstorm in KC November records has been 9″, so it can happen at this time of the year.  It also can happen in October, as we learned October 22, 1996 when up to 8 inches of snow fell.  The problem is, we haven’t had much snow in many years and it would almost be shocking to our weather minds if anything more than 2″ was in the forecast.  Okay, hang on. I must have snow on my mind.  Here are the October stats:

What a month we just had.  It was 91 degrees and 26 degrees 13 days apart.  We had the earliest measurable snowfall in KC history when 0.2″ fell at KCI Airport.  I only saw a few wet snowflakes mixed in with the rain on the Plaza.  And, the big second week of the month, and yes in this years LRC, where so much rain fell placing us with over 7 inches of rain above average. This rain wiped out what was left of the drought conditions.

So, we move on into November, and cold air is now building up over the high latitudes.  Take a look.

This map above shows the temperature forecast valid at 6 AM Tuesday.  Two pockets of very cold Arctic air is forecast to build up, one over Greenland, and the second over Siberia.  The pattern is supportive for this to build stronger into the middle of next week due to a big ridge forming aloft over eastern Alaska and western Canada. We will look deeper into this developing pattern in the next few blog entries.  And, yes, some models have started to show snow close to Kansas City.

There are a few showers this morning associated with a weak storm system, and then a second fast moving weak storm may bring some rain Saturday evening.  This will be followed by a potentially stronger storm early next week.  A lot to discuss.

Thank  you for spending a few minutes of your day reading the Action Weather Blog featuring Weather2020 and the LRC.  Go to the Weather2020 blog to join in the conversation.
