Good morning bloggers,

We have a major fall change in progress at this moment. The colder air will arrive between now and 6 PM this evening and temperatures will drop with a 100% chance of rain. Rainfall amounts will likely be in the 1/4" to 1" range. This rainfall will be quite beneficial to our fall foliage that is beginning to break out into some beautiful color. The trees need a good drink of water, and today is the day to quench their thirst.

The map above shows a large area of rain with a few embedded thunderstorms. This is valid at 5 PM this afternoon, and this is when our newscast on 41 Action News airs on Sunday's. I am working Sunday's now, so I will see you tonight at 5 and after the game tonight. The rain is developing now, take a look:

This first radar image above shows a band of light rain showers and a growing area of heavy drizzle centered on I-70. And, look at what is developing farther north:

Look at that thin line forming from Omaha to just south of the Kansas/Nebraska border. This is growing and widening, and heading our way. And, this rain is forming in the colder air. This rain cooled air region will spread overhead this afternoon with that temperature drop into the lower 50s likely. This will make today 35 degrees colder at 5 PM than it was yesterday at 5 PM, which was around 88 degrees. It will really sort of be a shock to the system, so get the raincoats out.

This is the first of a series of cooler shots of air for this week. The weather pattern is going through some huge changes as the new LRC begins developing in the next two weeks, but right now we have done our analysis and this weather we are experiencing now is more related to last year's pattern. The new pattern is still another week or two from beginning. So, hang on and we will keep you updated as we go on this weather "roller-coaster" ride.

We will be dropping into the 50s in the next few hours, and then the colder shot that arrives later in the week may drop us into the 30s. We are not expecting a freeze, however, but there could be a light frost in some areas closer to the Iowa and Nebraska borders. Here are the forecast lows for Friday morning:

Notice how there is a freeze over Iowa on this forecast map. I hope you are ready for the cooler weather. I have enjoyed the warmer weather, but my allergies are really hitting me hard this weekend, so I am ready for that north wind to begin blowing.

Kansas City Weather Time-Line:

  • Today: A 100% chance of rain. A few thunderstorms are possible and the rain may be heavy at times. 1/4" to 1" of rain is likely. The wind will increase to 30 mph by mid-afternoon. Temperatures dropping into the 50s.
  • Tonight: Decreasing clouds and breezy. The rain will shift south early this evening. Low: 48°

Thank you for spending a few minutes of your day reading the Action Weather Blog. Have a great Sunday!
