It’s certainly not the kind of weather that’s going to peak the interest of a lot of storm chasers here in Iowa, but it’s still a threat. A frontal boundary will set up shop over Iowa on Sunday and Monday, bringing with it the threat of severe thunderstorms. The graphic to the left shows the current risk area highlighted by the Storm Prediction Center.
Overall this does not appear to be a large scale event, but storms capable of producing large hail and strong damaging winds are possible. At this time I believe the overall tornado threat for Sunday and Monday to remain limited.
The frontal boundary will stall out over the state on Monday, current thinking is it will cut the state in half from east to west. As the atmosphere destabilizes once again during Monday after, another round of strong to severe thunderstorms will be possible.
Eventually this storm system will exit the region with little to no change in our weather pattern. Temperatures should remain near the 80 degree mark during the week before warming back up closer to 90 by next weekend. Just a good old fashioned summer pattern here in Iowa.
