Great Weather Now... And Severe Weather Sunday?

We're watching the weather patterns over the next couple of days very closely - and not just because we are hoping to have nice weather stick around (even though we are hoping for that). We're seeing the potential as a cold front moves in Sunday for some at least slightly organized thunderstorm activity - and involved in that will be the chance for some isolated severe storms.

This image below is forecasted precipitation through Sunday night at about 7pm:
You can see quite a large blob of future precipitation over eastern South Dakota and southern Minnesota. While that is not quite representative of exactly where rain will likely fall - it does give us a baseline for where to look for strong storms. Add into that a variable you've probably heard us discuss before: CAPE (Convective Available Potential Energy, or the energy available to help fuel a storm). Look at this image below - and know that basically anywhere a storm forms where there are shaded areas it will at least be a light thunderstorm:

So... your conclusion after reading this post is that: yes, you should expect rain and thunderstorm chances as we conclude our weekend - but no, you should not expect a major severe weather outbreak - at least not yet. We'll be watching just to make sure.

Have a great night & hopefully you can get outside!
