Cold morning

What the heck happen to summer? Wow temps this morning are in the lower to middle 40s with some upper 30s across Northern MN and Northern WI....My low here at my place was a cold 42.9 ° I see that KRPD also showed a low of 42....Looks like these below temps are forecasted by the long range models right through Aug 20th...Sure they may be a few warm days here and there but over all the temps will avg below norms.....
