The Iowa Storm Chasing Network (http://iowachase.com) reports the Severe Storm Prediction Center (SPC) is currently watching parts of southwestern Iowa for the probability of issuing a severe thunderstorm watch. It appears more robust storm initiation will occur over the next hour or two across south central Iowa. A large hail and perhaps an isolated tornado threat may develop over the next several hours as attempts are made for storms to increase in coverage and intensity across central Iowa
