We’ve been hearing a lot about the heat wave in the Midwest and it’s expansion to the East Coast. Meanwhile, Flagstaff’s temperatures have been dead on the average for the month to date. The graphic from HAMWeather.com shows temperature records for the last week. New high temperature records we set in a broad fashion across the United States. Just a note that some low temperature records were set in the West.

The rest of the world isn’t exactly following the North American heating trend. Below is a graphic of global surface temperatures for 2009-2011. Notice that global temperatures are lower now than in the last couple years.

The real drivers for the lower global temperature are ocean temperatures.

Europe, Africa, North America, Asia, Australia and Antarctica are all showing up as mostly above normal. But, by and large, the world’s oceans are cooler than normal. Interesting situation.

For Flagstaff, if we can get the daily heating from mostly cloudless morning skies, we should see some nice monsoonal activity this week.
