There is still a little bit of stormy weather to get through this weekend before we see a prolonged period of tranquil weather here in Iowa. The Storm Prediction Center has posted a moderate risk for extreme northern Iowa and a slight risk for areas along and north of Highway 30.
This threat looks a little troubling, but it’s not as serious as the threats we experienced earlier this week. Development should begin to our north and west. Even at the point of initial development, the risk for tornadoes is somewhat low.
As for Iowa, this looks to be a late night event, with storms bringing a threat of strong winds to Iowa. Certainly not a chase worthy event in our area but definitely something to keep an eye on.
Another threat for severe weather exists tomorrow, when a secondary boundary moves through the state. This could bring an increased risk for tornadoes, especially in far northwest Iowa where initial development might occur. For the rest of the state I anticipate the primary threat to be strong damaging winds through the evening and overnight hours.
With both of these threats I want to make a clear point, myself and my chase partner are both in a wedding this weekend (and missing another – big time for weddings!) so we will be unable to chase and provide as many updates as we would like. I realize this is unfortunate because a growing number of you turn to us during severe weather. But it’s that time of year and this an event I can’t and don’t want to get out of. I apologize for the inconvenience and hope you understand.
The good news is this new storm system will not linger in the area for a long time. The final round comes Sunday in the form of a much needed cold front. This front is not expected to pass at a prime time for storm development and therefore the risk for severe weather on Sunday is expected to stay east of Iowa. We’ll monitor this however, because any change in the front’s position and timing could alter that risk.
We’ll continue to monitor today and tomorrow’s situation as best as we can and bring you updates when we’re able to. But this looks like some strong to isolated severe summer time storms to me and not a major outbreak that Iowa needs to worry about.
