Strong heat wave will break

Above, you can see the anticyclone. This is the opposite of a storm or cyclone, and the major reason why we are in this heat wave right now. The air generally sinks under this high aloft. It isn't really high pressure aloft, but high heights aloft. It is now forecast to rapidly escape to the west and be near the Pacific northwest coast by Saturday. This will allow north to northwest flow aloft to develop bringing a cold front through which you can sort of see below on Friday morning. The GFS thinks the front is already south of Kansas City by Friday morning, but this could set us up for some nice thunderstorms. This is rather strange and let's wait to see how it looks on Wednesday. But one thing for sure.........the heat wave will break and we will cool into the 80s this weekend.

Have a great evening and remember to drink a lot of water the next two days. Good luck to those of you who picked this week as the hot one. I think there will be at least one more hot stretch coming up soon, although this is enough for me.

Yeah, I like to place an order for a cold front to hang around for a few days.
I would also like to place a side order of mild to moderate thunderstorms.
Please deliver to Harrisonville as soon as possible.
I have put the order in. We don't get orders like this often, and it may take 48 hours for us to make this up, so please be patient. The side order may be a problem. The ingredients will have to be mixed but sometimes it comes out as a light rain shower. But, as I said we have two days to try some other combinations.

That was funny Nigel...lol I hope Gary can make copies of that order for us too :) My in-laws have been in Alaska the past 9 days and it's been between the 50's and the 70's there. I'm not sure but I thought I heard them laughing at us a couple of times when I told them we were baking here ;)
Gary, why is KCI the official place for high temps, rainfall, etc? I was curious of how and why it's there and not downtown. Thanks and have a good a day!
One spot is just picked as the official site. It could have been downtown and at one time it was. Before KCI was built the downtown reading was the place of record. So most of our older records are actually from the downtown airport.
It really doesn't matter that much. The temperature can vary within a mile or two by a few degrees, especially in the early morning hours.

With the approach of the Up coming cold front, Im wondering if we could have some damaging straitline winds of 65 to 75 mph as the rain cools the air. Maybe some Hail as well if the storms get to rotating. I hope the Front pulls all the way through and does not come back as another warm front.
Steve, we must have a thunderstorm before we can wonder about the severe weather you are talking about. I am not convinced yet that we will have any organized activity.
