It did warm up to above normal here!
Sunshine and yesterday's high was 58°f. Overnight, the temperature dropped 30° to 28°. I bet those kinda temperature swings are real common for you, James. They are the bane of my gardening existence! Very few plants appreciate such daily extremes.
A 40° difference between daytime high and nighttime low is possible. That's what may happen about the time of a first or last frost. The day just cannot warm above 70° and then frost occurs by morning. Clear skies, sunny days, sparkling stars at night - freeze! And hey! This isn't a desert and at 2,000 feet, it's not very high ... now, I might be lamenting the PNW spring overcast here in a couple of months
