      Severe Thunderstorm Watch Issued

      Macon and Linn Counties are now under a tornado watch until 10 p.m. Wednesday.The following counties in the KTVO viewing area are under a Severe Thunderstorm Watch until 5 p.m. Wednesday...In Missouri : Putnam, Sullivan, Adair, Schuyler, Knox , Lewis, Clark and Scotland.

      In Iowa: Henry, Jefferson, Van Buren, Davis, Wapello, Appanoose, Monroe, Mahaska and Keokuk.Several rounds of thunderstorms are expected through the day and into the overnight hours. A warm front is forecast to lift northward towards northern Missouri bringing a chance for severe thunderstorms. The strongest storms through the afternoon and evening in this area would be capable of producing large hail and damaging winds. A few tornadoes are also possible in the vicinity of the warm front. A cold front will push southeast through the region this evening and tonight with a line of potentially severe storms forming along this boundary and sweeping across the forecast area during the overnight hours. As the storms evolve into a linear system, the threat of large hail will decrease, with an increasing risk of damaging winds. A few tornadoes are also possible within this line of storms during the evening and overnight hours.

      The repeated rounds of thunderstorms have the potential to produce widespread heavy rainfall with 1 to 2 inches of rain likely and possibly as much as 3 to 4 inches with storms that train over the same area. These rains could result in flash flooding as well as flooding on area creeks and rivers.Stay tuned to KTVO's Storm Team 3, and NOAA Weather radio throughout the day for the lastest updates.
