Some much need rain and snow melt is expected around Iowa this weekend. The latest water summary update, released by the Iowa Department of Natural Resources, shows poor stream flow conditions and groundwater levels at or near historic lows across the state. Tim Hall, with the DNR, says the good news is Iowa received above normal precipitation in both January and February. “That’s tempered by the fact that January and February are pretty dry months, typically, to begin with,” Hall says. “So, above normal precipitation in a dry month isn’t the greatest thing in the world to shout about.” Sioux, Palo Alto, Osceola and Crawford counties are especially hard hit by low levels of shallow groundwater, according to Hall.

“We’re seeing places in northwest Iowa that were struggling to keep up with demand last summer and they’re going into this year with groundwater levels lower than they were a year ago,” Hall says. “So, they’re starting off in a weaker position.” Across much of northern Iowa, much of the rain and snow melt this weekend will runoff directly in streams, lakes or low lying areas because of concrete frost.

“That involves an ice layer frozen into the upper most part of the soil profile, which prevents rain or snow melt from getting very far down into the ground,” Hall explained. Showers and thunderstorms are expected to develop across Iowa tonight and into tomorrow (Saturday). A cold front is forecast to move into the state by Sunday and bring a chance of snow.

Cass County Emergency Management Coordinator Mike Kennon reports the Marne Fire Department and Cass County Emergency Management Agency will host a Storm Spotter Training Program on Wednesday, March 13th, from 7-to 9-pm., at the Marne Fire Station. Kennon says a meteorologist from the National Weather Service (NWS) in Des Moines will be on-hand to provide participants with information about safely observing and reporting severe weather. The session is FREE, open to the general public, and no registration is required.

Each year, National Weather Service meteorologists from Des Moines travel to many counties they serve, to provide a comprehensive multi-media spotter training presentation. The course contains information about severe weather climatology, severe thunderstorm types, different severe weather threats and how to identify them, how to report severe weather, spotter safety and severe weather communications. Spotter training classes typically last between one and two hours.

Trained Spotters provide an invaluable service for the Weather Service. Real-time observations provide a truly reliable information base for severe weather detection and verification. Timely and accurate observations assist NWS staff members in their warning decisions, enabling the NWS to fulfill its mission of protecting life and property.

The Spotter Training class on March 13th is sponsored by the Cass County Emergency Management Agency. Questions concerning the class should be directed to the Cass County EMA coordinator, Mike Kennon at 712-254-1500.
