Strong/Severe Storms Possible Tonight-Friday Morning
The potential for severe weather is there across all of southern Minnesota & northern Iowa tonight, lasting though tomorrow morning. This is a little different than what we are used to in terms of timing for severe storms. Here's why...
Storms should fire up in the eastern Dakotas later this afternoon/evening, advancing SE throughout the night.Expect the storms to get here around 10 pm or so as a Mesoscale Convective System (or MCS for short).
This is one of the forecast models showing the MCS pushing through the area during the early morning hours on Friday (snapshot is the forecast for 4 a.m. Friday).
Basically an MCS is a huge complex of strong/severe thunderstorms (we see these often overnight in the summer) that pack strong winds and heavy rain. Hail doesn’t look to be too much of a threat this time around, but I’m saying I am completely ruling out the potential large hail. The storms will last into the early parts of Friday morning.
Be sure you have your weather radios on tonight, so you can hear the alerts for any watches or warnings that are issued. Stay tuned to ABC6 News on air & online, your Storm Tracker 6 Weather Team will be here tracking the storms through the night, bringing you the latest information.
