A Few Rounds of Storms

Sunday night did bring a few severe weather reports across the state, mainly of marginally severe hail around an inch in diameter and several wind gusts of 60 mph or so. The wind was strong enough to take down a few trees and power poles in a line roughly along Highway 30 from Sioux City towards Fort Dodge. We've held quiet since then, with temperatures still a little below normal for this time of year.

We'll be able to change the temperature aspect and finally feel some good summer heat and humidity for a few days for this weekend. This will also bring us the conditional chance of some thunderstorms during the late afternoon and overnight hours beginning tonight, and likely lasting through the weekend. At this time it is too conditional to really pinpoint any good chances of a round of thunderstorms, but rather good to mention that if thunderstorms do persist or develop into Iowa they are likely to have a chance of some large hail and damaging winds.

Our first chance will be across western Iowa tonight as a potential MCS will swing by the state coming out of the Dakotas. An additional round of storms may also be coming into northern Iowa by the early morning hours as the threat of an additional MCS seems possible. After these rounds of storms have a chance to move through, a good setup will be featured over portions of SD/MN/IA for severe weather. However, the warm air at the surface will also translate into the mid-levels and may keep us capped from thunderstorms. Sunday also appears to have a chance of thunderstorms, with the likelihood of an upgrade of the severe weather risks issued by the SPC in later outlooks.

While dodging the rounds of thunderstorms, enjoy the warm and humid air as temperature soar into the upper 80s and 90s and dew points rise into the upper 60s and even 70s creating the typical miserable summer feel. Additional updates may be given if warranted...
