Saturday rainfall won't relieve drought conditions

Monday, July 30, 2012 | 6:55 p.m. CDT

COLUMBIA — Despite the light rainfall on Saturday evening, the current drought conditions are likely to persist.

Columbia only received about one-third of an inch of rain, MU climatologist Pat Guinan said. The rainfall was too light to make a difference in soil conditions or impact the severe drought.

The drought won't end without frequent, significant amounts of precipitation over an extended period of time, Guinan said.

MU's Sanborn Field has recorded about 4 inches of rainfall since May 1. A normal rainfall for that period would about 14 inches, Guinan said. This 10-inch deficit has lead to an extreme drought situation and explains why light, infrequent showers have no chance of breaking the drought.

With no indication of widespread precipitation in the near future, light rains will continue to have little or no effect, Guinan said.

Current forecasts predict only a 20 percent chance of precipitation Monday evening, and there is no significant chance of rain in the 10-day forecast, according to The Weather Channel.
