Some Stats on the Cool Temperatures on 7/15

An unseasonably cool airmass associated with a mid to upper-level low pressure system settled over the Upper Great Lakes on Tuesday, July 15th. Several record low maximum temperatures were set across the region as low clouds and showers prevented warming from the abundant sunshine common to mid-July. Here are a few stats about the 53F high temperature observed at NWS Marquette on 7/15:

- Average high for April 25th and October 15th.

- 6th coldest July day since records began in 1961, but warmer than the 52F observed just last year on 7/28.

- 40th time the temperature failed to reach 60F on a July day since 1961 (average of around once per year).

- 6 degrees warmer than the 47F high temperature observed at the Grand Marais breakwater light.
