Hot and humid weather will prevail today, with a heat advisory in effect until tonight, when a cold front is expected to bring showers and thunderstorms to the region. The area is facing increased risks for strong to severe storms, including potential wind gusts exceeding 70 mph and the formation of a derecho as the storms progress eastward.
This morning, expect warm temperatures in the upper-80s to low-90s, combined with high humidity. The weather advisory is in place due to heat index values potentially reaching 105 in some areas. However, as evening approaches, a cold front will advance into west-central Minnesota, triggering a line of showers and thunderstorms between 7 pm and 8 pm. This front is projected to sweep through southern Minnesota, hitting the Mankato area by 9 pm to 10 pm.
The primary concern from these storms will be damaging winds, but there is also a possibility of hail and tornadoes given the prevailing environmental conditions. The storms could be classified as a derecho, which represents a significant windstorm associated with fast-moving showers and thunderstorms when they cover a substantial distance with damaging winds.
As the front drives this storm system forward, the severe threat is expected to diminish after midnight. However, showers and thunderstorms may linger into early tomorrow morning, with temperatures cooling to the upper-60s.
Looking ahead, tomorrow’s weather will fluctuate between mostly cloudy and partly cloudy conditions with continued chances for isolated showers and thunderstorms. Afternoon temperatures are anticipated to rise into the low-80s with light winds. Tomorrow evening will see similar weather, with the potential for another round of late-night thunderstorms as temperatures drop into the low-60s.
As the week progresses, cooler and quieter conditions are expected with highs in the mid to upper-70s, particularly from Thursday through Sunday. The clear skies should provide a pleasant environment, offering residents a welcome reprieve from the recent heat.
Next week appears to continue with mild temperatures, highs in the upper-70s to low-80s, and a mixture of sunny and partly cloudy skies. Overall, the break in oppressive heat brings a refreshing change, and residents can look forward to more comfortable weather patterns in the upcoming days.
Stay safe during the storms and ensure you’re prepared for the changing conditions.
