Arctic Air Blasts In Again

Good Morning Bloggers,

We just experienced a rather fascinating weather day in Kansas City. We went from a fluffy and dry snowfall in the morning, with temperatures in the teens, to a big warm up to above freezing with a mixture of rain, freezing rain, sleet, and snow during the late evening hours. The high temperature reached 33 degrees at KCI Airport. And, then an Arctic Blast arrived early this morning and now temperatures are crashing as you wake up and read today’s blog entry.  It was a bit frustrating, but in the end fascinating and fulfilling for myself last night. I experienced rain, freezing rain,  sleet, and then snow. The different types of precipitation went back and forth for two hours before finally ending with around a half inch of snow leaving a sheet of white on everything, and it is beautiful this morning.

Kansas City Snowfall:

  • 2.1″ fell yesterday at KCI Airport between the two winter weather precipitation events
  • 4.7″ has now accumulated this season, which means we are now just 0.2″ away from last years total

High pressure is building in from the north and our pressures will be going way up peaking on Tuesday.  A WIND CHILL ADVISORY has been issued and it will begin tonight at 6 PM.  Very cold wind chills will happen tonight and this could cause frostbite in 30 minutes or less to exposed skin. Wind chills are expected to be as low as 25 degrees below zero.

A 1052 mb surface high is forecast to weaken to a still large 1045 mb surface high near KC by 6 PM Tuesday.  This is equivalent to a 30.86″ pressure, which is quite high.  Look closely, as there is only low pressure left in Canada, so the Arctic air is basically emptying out  and expanding into the Gulf of Mexico.  The pink and purple shaded area shows mixed precipitation all the way down to the Gulf coast again. This has happened multiple times in this years pattern already.

Later this week we will be seeing a rather big moderation and retreat of the Arctic Air.  South to southwest winds will be blowing from Texas into southeastern Canada:

We will then be monitoring a storm system moving into the western states, which is right on schedule according to the LRC.  It appears this next storm will produce winter weather again, but most likely north of KC later this weekend. This something we are monitoring closely and will go more in-depth with in blogs later this week.

Kansas City Weather Timeline:

  • Today: Falling temperatures steadying out in the single digits later this morning. Windy, with northwest winds 10-25 mph adding a strong “bite” to the cold air and creating dangerous wind chills.
  • Tonight:  WIND CHILL ADVISORY. Wind chills will create dangerous conditions and time outdoors should be limited to minutes. Wind chills 25 below zero are possible. The low temperature will drop to 3 below to 10 below across the area
