We’re seeing a shift in weather patterns across Western Wisconsin. A cool down ahead then a bit warm up followed by some thunderstorm potential late week and into the weekend.
3 Things To Know:
- A stray shower or thunderstorm is possible this afternoon in central Wisconsin.
- Warmer temperatures approaching the 70s and 80s are expected by this weekend.
- Monitor Sunday and Monday for potential severe thunderstorms.
Current Thunderstorm Risk
Western Wisconsin conditions remain conducive late Tuesday for some isolated convection.
As this upper wave moves southeast, it may trigger brief showers. However, the primary concern will be gusty winds associated with any storm activity, so plan accordingly if you’re heading outdoors.
Temperature Trends
Looking towards the end of the week, we can expect a significant warming trend. Temperatures are likely to rise into the lower 80s by Friday and Saturday. While the forecast suggests warm days ahead, it’s important to note that readings might stay just below 80 degrees. Conditions will remain above the norm for mid-May, perfect for those outdoor activities.
Impacts of the Weekend Thunderstorm Potential
This weekend brings increasing humidity and an uptick in chances for showers and thunderstorms. Starting Saturday, the atmosphere will be primed for possible storm activity. The shift in flow will introduce moisture that may lead to thunderstorms by Sunday. As we approach Monday, there could be a low potential for severe thunderstorms depending on moisture levels and storm dynamics.
“Given increasing southwesterly flow aloft atop southerlies at the surface, this could lead to severe thunderstorms.”
As always, it’s wise to keep an eye on evolving conditions through the weekend, especially for outdoor plans.
In Summary
In brief, expect some isolated showers this afternoon, a warm-up towards the weekend, and increased potential for thunderstorms as we head into Sunday and Monday. Stay tuned for updates and be prepared for changing conditions.
