It’s quite possible that the drought will get worse once again in the Great Plains and eventually expand eastward across the Mississippi River towards Indiana and Ohio sometime this summer.

Forecasters at Harris-Mann Climatology are predicting that the severe drought over the southwestern U.S. is expected to intensify as moves eastward over the central U.S.
Many climatologists believe that the very dry conditions seen in Southern California, Arizona and New Mexico in early 2013 are getting worse. For example, Lake Mead, beneath Hoover Dam, is currently at its lowest water level ever. Irrigation supplies in California will be cut drastically this summer’s growing season due to far less snowmelt than normal.
“We currently are in-between the cooler La Nina and the warmer El Nino sea-surface temperature event in the south-central Pacific Ocean. We call this ‘La Nada’ and we often see droughts migrate into the central U.S. during the late spring and summer seasons,” according to Harris-Mann Climatology Meteorologist Randy Mann.
According to the U.S. Drought Monitor, areas to the east of eastern Iowa, central Wisconsin and western Missouri no longer have drought conditions. Instead, they currently have massive flooding eastward through Ohio. By contrast, moderate to extreme drought conditions are still being reported in Wyoming, Colorado, New Mexico, Kansas, Nebraska, Oklahoma, Texas and South Dakota. Severe drought has also been expanding in California, Nevada, Utah and Arizona. Earlier this year, the area of drought in the U.S. was even larger when compared to the same time a year ago.
According to Harris-Mann Climatologist Cliff Harris, “We are still in a long-term cycle of wide weather ‘extremes’ across much of this country and the rest of the world. Many of us recently saw March and April dust storms develop from southern Idaho southward through the Intermountain West into Arizona. We believe that the high pressure ridge over the western U.S. responsible for the prolonged drought cycle will begin sliding off to the east into the nation’s heartland, again like last year, sometime during the 6-week period between early May and mid June."
