An Excessive Heat Warning is in effect through Saturday!
Good morning bloggers,
We hope you had a nice celebration on Independence Day! It was 102° yesterday, our sixth 100 degree day so far this summer with many more likely on the way. It was the hottest Independence Day since 1954 when it was 103° that day. The heat wave will grow stronger before a weak cold front moves through this weekend:
Heat Wave June-July 2012
- Day 1, June 27: 102°
- Day 2, June 28: 105°
- Day 3, June 29: 102°
- Day 4, June 30: 101°
- Day 5, July 1: 99°
- Day 6, July 2: 97°
- Day 7, Today: 100°
- Day 8, Wednesday: 102°
- Day 9, Thursday: 103° Forecast
- Day 10, Friday: 105° Forecast
- Day 11, Saturday: Near 107° Forecast
We will be working on some special weather graphics to describe this next change in the weather pattern due in late Saturday night. It looks like the heat wave will take a break Sunday into Tuesday. A cold front will be approaching Kansas City Saturday and this will be a front that stretches from Colorado to New York. Here is a surface forecast map valid at 7 PM Saturday:
How much cooler it will get behind this front is still something we are figuring out, but it will drop at least 10 to 15 degrees, if not a bit more than that. Unfortunately it may be 105 to 110 degrees ahead of this front so a 15 degree drop would get us only down to near 90°. There will be a chance of thunderstorms near the front Saturday night, but right now we have a very slight chance at any one location. The dry summer continues and now it is becoming a serious drought. This is going to be a tough one to break with the jet stream still retreating north as the peak of summer is still a few weeks away. Take a look at this rainfall forecast that I awakened to this morning:
This map, above, shows there rainfall forecast added up over the entire 06z GFS model run through the next sixteen days. Kansas City is just east of the minimum rainfall amount forecast over Kansas of almost no rain. Hopefully this overnight run of the GFS model is just wrong.
Have a great Thursday.
