The United States of America celebrates 235 years of independence under an extreme summer weather pattern. Records are being set for heat . . . and for and deep snow. Four ski areas are open, thanks to the snowiest winter in more than a decade. One of the ski areas is Arapahoe (shown above today, Sunday July 3, 2011) in Colorado. Down the Interstate from Arapahoe in Denver, the temperature reached 95° today. Plenty hot, but not as hot as it was on July 3, 1874, when the record of 101° was set. Here in the East, temperatures have been hot, too. Detroit MI reached 99° on July 2, breaking the record of 98° set 100 years ago.
For the first time in months, we have no closed low near the East Coast or North Atlantic. That means a more classic west-to-east flow, with a warmup for New England. A series of fast-moving short waves will race from the Pacific to the Atlantic across southern Canada this week. Usually that means a warm and dry pattern, with a thunderstorm every other day or so. But we have to keep an eye on the tropics.
