At 0700 it’s 80*F with humidity to match. Today should top out around 97*F but we haven’t cracked 100*F yet this year. Just another north Texas summer.
These guys didn’t have as much humidity to deal with but a dry heat is still hot. Add in a little breeze and it’s like standing in front of a blow dryer or convection oven.
