We just had one of the wettest, coolest springs in a long time here in the PNW - really haven't had a spring like this since 2011. And then right on cue the summer switch was turned on a couple of days ago and we're expecting to be in the 90s for a few days (up to 98 on Sunday). It's kind of jarring to go from ~60F cloudy&wet just about every day for the last couple of months to 90s over the course of just a few days.
Here in the high desert of northern NM, we've just been through the opposite. After a month of highs in the 90s, the last week has seen daily highs in the 60s, and finally some rain. It is weird but we're delighted.
Meh, that kind of weather change is normal for the inland American southeast. We had a temperature change a few years back in excess of 40 degrees in 18 hours.
