For the long holiday weekend it looks warm and dry for Colorado and southern Wyoming. The chance for clouds and an afternoon thunderstorm may be on the increase by Monday, and temperatures may be just a little less warm. Daytime maximum temperatures Friday-Sunday in the Front Range urban urban corridor are likely to range from the mid 80s to around 90 (a little cooler in Cheyenne) with Saturday bringing the best chance for topping 90. Unlike northeastern Colorado, other parts of the state have been somewhat dry in May and those areas may see elevated wildfire risk this weekend.
We should get close to some of these records, and it’s not out of the question that there may be a few locations around the region that set a record high. Record high temperatures in Denver are:
Friday 91 (1964), Saturday 95 (1942), Sunday 93 (2006),
and for Boulder:
Friday 87 (2013), Saturday 91 (1969), Sunday 92 (2006).
