It Got Drier Last Week! HUH?

Though the Mississippi fought floods and thunderstorms drenched the South this May of 2013, the US has gotten drier.

Incredibly, despite all the rainfall, 62% of the nation is dry and 48% is in drought conditions! Even with all the rainfall, almost half the nation is still suffering from prolonged drought.

48% of the U.S. is in drought conditions.

The problem is that after two solid years of dry weather, it’s going to take a lot of rain to break the drought. The parched soil soaks up any moisture quickly and needs even more. While there was heavy rainfall over the past two weeks, it has been concentrated in a few soggy areas. Most of the nation only received a day or two of showers or storms.

Basically, all the cold we didn’t receive this winter is finally plunging south. Cold air doesn’t hold much moisture. Where the cold air crashes into warm moist air from the Atlantic or Gulf of Mexico, it rained. (Yes, Atlanta, I’m thinking of you and that 6 inches of rain you received. You needed webbed feet!) Where there was just cool air, it remained relatively dry.

There is some good news. As I noted earlier last month, tornadoes are finicky and it has just been too cold to generate many storms. The same wedge of cold air that limited rainfall has also limited deadly thunderstorms. Normally we would have averaged 625 tornadoes by now and we have only had 237. This season has set a 60-year record and is in the lowest 10% of the history of tornado seasons.

Overall, it looks as if there should be enough rain for planting, once the weather warms up. But, look out. The soil is still thirsty and heat waves could cause some real problems. On the other hand, with the weather the way it has been lately, a nice warm heat wave sounds almost cozy.
