Very HOT Saturday...Updated

It is a hot Saturday afternoon at 4:00 PM, but temperatures have cooled down a degree or two since 3:00 PM, so here is the surface map at 3:00 PM this afternoon with todays high temperatures and the front I drew in:

The front is just inching our way, so after highs today in the low to upper 90's with 97 degree weather in Kansas City, Sunday will hold much of the same with very similar high temperatures. Eastern Kansas and weatern Missouri will likely be in the 95 to 100 degree weather. Accompanie this with high humidity and dewpoints in the 70's to near 80 in spots, heat indicies will likely be between 100 and 108 degrees.

One thing that has been in our favor during this heat has been the strong southerly winds keeping the air mixing and becoming stagnant. This helps with the humidity, but also with the air quality, keeping it pretty good. Sunday will have a little bit weaker winds, so you will feel the heat more, but they will be strong enough to keep the air mixing - between 15 and 20 mph.

The front should continue its inching path toward us, and the data is saying it will push through. This will likely lead to a chance of some showers and thunderstorms late Sunday night into Monday. There could be some heavy rainfall, but I will wait till tomorrow to talk about this.

Morning entry is below.


It was a very warm night last night with temperatures in the 70's and high humidity. Right now as of 7:00 AM, it is fairly cool outside, but later today, the winds will increase out of the south gust to 20 - 30 mph once again and set the stage for the heat to pour into the area.

In preparation, the NWS has issued Heat Advisories for the area. Highs today should range from the low 90's in northern Missouri, to the upper 90's around the Kansas City area. Along with the heat, dewpoints will be in the 70's. This steamy airmass will make it feel even hotter as heat indicies rise to 105 at times.

More thoughts later this afternoon...
