Just in time for the beginning of August, the jet stream is undergoing a readjustment that will bring a noticeable change in the weather over the United States for the next couple of weeks. The shift should bring cooler weather to much of the eastern U.S., while the West Coast stays as hot and dry as ever.

The thing about March is that it lures you in with springlike temperatures, chirping birds, bumbling bees, and just when you start to let down your guard—WHAM!—you get smacked with a winter storm. It happens almost every year, but I am so sorry to say that it's probably going to snow this weekend.

In a normal year, the southern United States would see severe weather on a weekly basis by the end of February. But that's a normal year, and this is 2015. For better or worse, severe weather across the United States is at an all-time low since records began nearly half a century ago.
