3 Things To Know:
- Expect isolated showers this afternoon, primarily east of the Mississippi River.
- Warm temperatures in the 90s and increased humidity are expected next week.
- Uncertainty remains regarding precipitation potential as summer heat sets in.
Current Weather Outlook
This afternoon, Western Wisconsin may see scattered showers, especially east of the Mississippi River. Though forcing is weak, this could lead to brief periods of precipitation. Overall, the likelihood of thunderstorms is low, sitting around 10-20%. Expect these showers to diminish as daytime heating wanes this evening.
Seasonal Temperatures Through the Weekend
Friday and Saturday will wrap up the week with near-normal temperatures before a shift occurs next week. As a surface high pressure system moves across the Great Lakes, cooler easterly breezes will follow. However, by Saturday, southerly winds will kick in, setting the stage for hotter and more humid conditions.
Implications for Next Week
Starting Sunday, a warm air mass will push through, contributing to expected high temperatures in the 90s and heat indices reaching the lower 100s. There may be a chance of isolated showers and thunderstorms, especially as the cap builds through the day. However, confidence in rain variability remains high.
“Next Week: Summer Heat Arrives”
As the week progresses, expect a near-continuous influence from a strong upper-level ridge which will dominate our weather. Moisture will increase, leading to higher humidity levels. While there’s a chance for localized rain events, the overall heat is what we can confidently anticipate.
Conclusion
Prepare for a pleasant end to the week, but keep an eye out for rising temperatures and humidity as we enter summer next week.
