Much Cooler Air Arrives This Afternoon

Good morning bloggers,

A cold front is approaching. It will move through this afternoon, and before the sun sets tonight it will be dropping into the lower 60s or upper 50s, then down into the 40s by morning.  Here is a look at the temperature forecast at 2 PM today:

There will be a chance of rain and thunderstorms as this front moves through this afternoon.  The window of opportunity for rain showers and thunderstorms will briefly open for around an hour or two as the front approaches and moves through your location. Rainfall  amounts of a trace to 0.50″ are possible.

Kansas City Weather Timeline:

  • Today:  A few morning clouds with southeast winds. Temperatures will warm up to near 80 degrees by 1 or 2 PM.  A cold front will then sweep across the region by mid to late afternoon.  The temperatures will drop into the 60s rather quickly with a chance of showers and a few thunderstorms near the front as it passes through.
  • Tonight: Clearing and turning colder. Low:  45°
  • Wednesday:  Mostly sunny and cooler. High:  66°
  • Thursday:  Mostly sunny. High:  73°
  • Friday:  Increasing clouds. High:  71°

The Changing Pattern:

This next graphic below shows four previous GFS model runs valid around ten days from now.   Look closely at the trough over the western United States. On the most recent run there is a deep trough and storm over the western United States, while on all of the previous runs this trough is either not there at all, or just a weaker system:

The models are all over the place with possible solutions for the beginning of the new LRC. We are still in the old pattern, and the computer models are projecting from our “horrible” pattern from this past year in the KC region. How this actually sets up is what is important, not what the computer models show.  So, as I say every year, “be patient”.  We have the next six to twelve weeks to monitor closely before we make any conclusions.  I will say it in advance, that I will not jump to conclusions, so I recommend patience and understand if I do not respond to any questions about this developing pattern until we have some answers which usually takes until sometime in late October into November.

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