Tornadic Activity in the Heartland

I will be traveling through the Heartland from May 10-May 20 with a travel trailer are tornados predictable?

Tornadic activity in May in the Heartland

Seriously, you're going to be in the Heartland Region in mid-May and you want to know if there will be tornadic activity? Considering that this is basically "tornado alley", I think it's safe to say "YES" the chances are pretty good that there will be some kind tornados in that region in that period of time. I would be more surprised if there wasn't.

Outdoor wedding

Curious about temperatures Sept 22,2018 for an outdoor wedding in Spirit Lake,IA

September Weather

We’re predicting scattered thunderstorms and warmer-than-normal temperatures around that time. It’s always a good idea to have a back-up plan in case the weather doesn’t cooperate!
