Our fabulous weather continues to start off the week as temperatures this AM have started out in the upper 50s, officially dropping to 57° @ KCI. The record is 54° set back in 1995. Mary asked me on the news last night if we’ve started July so “cool” before and actually we have, many times…in 2007 it was 79° and in 1995 it was 75°…one of the chillier starts to the month was in 1988 when we started @ 66° for the month. Regardless another great day in a string of great weather for the KC area for late June and now early July.

I’ve been sending out numerous tweets over the last couple of days highlighting the changes compared to one year ago when we were battling temperatures 100-105° for the beginning of July. Just comparing the two Junes is an interesting study of differences…take a look.

That is just for the month of June…how how overall for the year through June 30th…this next graphic shows the differences between the number of 90°/100° days through 6/30…

On average we get about 36 days with highs of 90° or above…so far we’re at 7 and I don’t think we’ll get there for the next week or so, perhaps through the holiday weekend.

We’ve talked about this a lot lately but basically in the upper part of the atmosphere there is a big(!) ridge out to the west, and a decent trof associated with a weakening upper level storm to the immediate east of the KC area…here is a look at the flow aloft from NEXLAB also combined with the water vapor satellite picture…

There is also a big ridge off the east coast…so we have a ridge-trof-ridge pattern that tends to be stable and slow changing. Hence the continued decent weather for us. Thos ridges, mainly the one out west are the heat wave generators…and boy the west sure knows about that. Yesterday Las Vegas tied their ALL-TIME high temperature by reaching 117°.

Death Valley hit 128° and Phoenix hit 115°, for record highs as well. There were a bunch of daily records as well…here is a sampling from Storm2K.

For a little perspective on what they’re expecting over the next couple of days…take a look.

You can see the heat nicely on the forecast map for the RAP model for later this afternoon…notice where the core of the heat is, from the SW up through E WA state where more records are likely to tumble. Click on that image to make it larger!

The heat in the SW should have the edge taken off as the week moves along, as the ridge starts to push farther northwards…this means that the worst of the above average temperatures will shift farther north as well.

Finally the weather created a tragedy last yesterday as a lightning sparked fire took the lives of 19 firefighters, the largest mass firefighter tragedy since 9/11. They were fighting a fire near Prescott, AZ which is between Phoenix and Sedona, AZ. They were most of the force in Prescott and members of the Granite Mountain Hotshots who are trained to deal with these types of wildfires. Here is a look at the front page of the newspaper in Prescott, AZ.

and also the front page of the Arizona Republic out of Phoenix with a map better showing the location of the fire in Yarnell, AZ.

Additional details are also avail on our FOX station in Phoenix.
