The latest NAM forecast cranks the 700-mb temperature up to 18.7C at the Salt Lake City airport by 6 PM tonight. Scorching.
The GFS is just a shade cooler at 18.3C. Yesterday the 700-mb temperature was 15.4C and we hit 98F. At 10 am we were already 89F. 100 is in the bag and I think we have a shot at 102 for the max. Stay cool.
