Map of the risk of heavy #precipitation from April 25 to May 1:

Tornado Warning continues for Farmington IA, Bonaparte IA and Mount Sterling IA until 4:30 PM CDT

3:36 pm CDT SPC update regarding the storms pushing into southwestern MN at this time. Expectation is that storms will continue to be on a downward trend. See details at this link: spc.noaa.gov/products/md/md…

Severe Thunderstorm Warning continues for Cedar Rapids IA, Marion IA and Hiawatha IA until 3:15 PM CDT. This storm will contain wind gusts to 70 MPH!

Tornado Warning including Rock Rapids IA, George IA and Boyden IA until 3:30 PM CDT

Severe Thunderstorm Warning including Iowa City IA, Anamosa IA and Mount Vernon IA until 3:45 PM CDT

Our latest thoughts with the second axis of developing storms across far southern IA / Missouri moving northeast. Potential for all hazards if they can mature, including some tornadoes. The northern extent of the severe risk is not certain. Hail is a risk with any storm.

Mesoscale Discussion Summary: All severe hazards remain possible across parts of northern Missouri, central/eastern Iowa, northwest Illinois and extreme southwest Wisconsin for the next several hours. #iawx

Tornado Warning including Le Mars IA, Maurice IA and Brunsville IA until 2:30 PM CDT

Severe Thunderstorm Warning including Pella IA, Knoxville IA and Chariton IA until 2:00 PM CDT

A tornado watch has been issued for parts of Iowa, Nebraska and South Dakota until 7 PM CDT

Severe Thunderstorm Warning including Bloomfield IA, Eldon IA and Moulton IA until 12:30 PM CDT

A new Tornado Watch is possible as clearing skies are enhancing instability. 'However, the dry slot is punching into this area which will dry the atmosphere from the south. The window for sufficient instability will therefore be somewhat narrow.' #iawx

Severe Thunderstorm Warning including Ames IA, Fort Dodge IA and Boone IA until 12:45 PM CDT

As storms continue to lift north, there will continue to be a threat for tornadoes, as we have seen one radar confirmed in the warning in this loop. Strong straight line winds and small hail will be possible too with these storms. #iawx #tornadowatch
