The hottest days of summer are upon us. Daytime highs will approach 90 degrees as an upper-level ridge of high pressure reduces mixing and results in mostly sunny skies. Thursday will be the hottest day with some nearby areas close to 100 degrees. The last 100-degree day in the Twin Cities was July 6, 2012 when the mercury reached 102 degrees.
Warm conditions under mostly sunny skies will enhance ozone production and encourage poor air quality. In addition, winds will remain light under the bubble of high pressure inhibiting pollution dispersion. This means that air quality will be rather poor, especially Thursday. Those that suffer from asthma or a respiratory illness may need to limit the time on the bike and/or complete outdoor activities early in the day.
Best chance of wet trails will be Wednesday and this weekend. Heavy rain on Saturday could leave trails too wet to ride into early next week. Stay tuned.
Summer brings warm afternoons perfect for biking, but the summer heat and humidity can also spark thunderstorms and severe weather. Be prepared for any type of adverse weather headed your way with Aeris Pulse.
