There is a small chance for storms tonight mainly for SW MN, but otherwise a quiet evening is expected. Tuesday will be quite hot, followed by another hot day on Wednesday. Heat indices will be over 100 degrees on both days, so be sure to practice heat safety!

What are some good heat safety practices to follow? Here are some things you should do! 🥤 - Be sure to hydrate 🧴 - Wear sunscreen, light clothes, use sunglasses 🕰️ - Plan your activities in cooler parts of the day 🐶🧓👶- Check on pets, the elderly, and children

What about things that you should not do during the hottest parts of the day? 🍲🥘- Eat big meals (they raise body heat) ☕️ - Caffeine (speeds up dehydration) ⌛️ - Spend long periods outside with no breaks 🚘 - 𝗡𝗘𝗩𝗘𝗥 leave children or pets in a vehicle

As the sun continues to descend, we are getting a better look at the coverage of the smoke aloft. Notice all of the green? That's all smoke. Normally we would expect to see a lot of deep blue in this false color image, which would represent the surface.

Yep. Another hot day, with highs in the mid 90s to just over 100. Unfortunately, it will be even hotter for Wednesday. It does look to cool down for the end of the week though!
