Good morning bloggers,

We have a dramatic change moving across the Kansas City region this morning. A cold front is moving through with temperatures crashing and some rain is moving in. Here is the radar as of just before 7 AM, and then the broad view showing the snow moving across Nebraska:

The cold air is now blasting in as this rain moves across. The band of rain is moving fairly fast and this will produce rainfall amounts in the 0,05" to 0.50" range. The half inch amounts will come if you get in one of the heavier downpours for more than a few minutes.

When I was on the air last night at 10 PM, this is the surface map we showed:

And, here is the current surface map early this morning showing the cold blast arriving.

7 AM This Morning:

There is a weak low pressure area right over KC at 7 AM. As this moves past the city by 9 or 10 AM, the wind will increase from the northwest and the rain will push off to the north and east. The window for rain is open now, but it will close up before noon.

We need the rain:
Today is the first rainfall of the month, and we will be able to add some numbers to this months total.It has been extremely dry in the past few months. Take a look at September and October:

The LRC begins each year around October 6th, and what happens in October and November set the stage for what will happen in the next year. Two years ago we had over 64 inches of rain, which was the wettest 12 months in KC history. And, then it dried out significantly with only 33 inches of rain last year, ending October 5. Take a look:

Before this morning, we had only 0.88" since this pattern began around October 6, so today's rain, and this weekend's chance of rain are actually rather important. I have added in the 0.11" that has fallen from this mornings rain, and hopefully I get to add to this total. Let's see how much falls.

Kansas City Weather Timeline:

  • Today: Much colder with rain ending before noon. Windy, with winds up to 30 mph from the northwest and north. Wind chills in the 20s and 30s, so bundle up. Temperatures dropping into the lower 40s.
  • Tonight: A freeze is likely with the wind becoming calm. It will become clear with a low of 29°
  • Wednesday: Mostly sunny with light winds. A great fall day. High: 55°

The weather pattern continues to set up, and we are working on our winter forecast which will be ready in a couple of weeks with our first look.

Thank you for spending a few minutes of your day reading the Action Weather Blog & sharing in this weather experience. Have a great day.
