Storms are ongoing in much of northwest Minnesota today, As the day progresses, look for storms to increase in coverage in western Minnesota. A few storms may develop in the early afternoon, but it looks like the main threat will be for a line of severe storms to develop in western Minnesota early this afternoon and move east into eastern Minnesota this evening.

Unless a few renegade storms pop up near the Twin Cities earlier this afternoon, it appears the most likely window for storms and potential severe weather in the highly populated Twin Cities area will be between 4pm and 9pm tonight.

Have the weather radio tuned up and keep an eye out for severe storms today. Here are a few key resources to track potential sever weather today.

    Since that outlook was issued, SPC extended the moderate risk into west-central Minnesota on the 1630 UTC update.

    About a half-hour ago I went outside here in the Twin Cities and noticed a decent number of altocumulus clouds with decent vertical development on them.

    It’s hard to focus on work today, darn it.

    And, if it means anything after my “open mouth swallow foot” comment yesterday, I will be listening to MPR on my way home this evening to catch the latest weather headlines.
