High Pressure System To Blame For Dry Conditions

Last updated on Thursday, June 21, 2012

(UNDATED) - There’s no El Nino or La Nina to blame for the continued lack of rain in Indiana, as forecasters say we are simply stuck in a cyclical period of dry weather.

Meteorologist Dave Tucek with the National Weather Service office in Indianapolis says a high pressure system has parked itself over the state for a good portion of the last two months, which has caused storm tracks to push to the north, bringing heavy rain and some flooding to states such as Minnesota and the Dakotas.

Tucek says some cold fronts have pushed toward Indiana, but says most of them have dried out by the time they arrive

One reason is a lack of moisture from the Gulf of Mexico. Tucek says ideally, the moisture would flow directly from the South. Lately, Gulf moisture has been flowing from east to west, pushing the moisture toward the Plains states.

Tucek says some of their computer models show we could see some rain next week, but says that depends on whether the flow of Gulf moisture shifts toward Indiana as cold fronts push through.
