Yesterday evening, I needed to wear earmuffs and gloves when walking Parker because of the 7°C weather. Yes, it's the middle of May, but we've had a really screwy spring this year.
Today I don't need gloves. Our official temperature bloomed from 8°C to 26°C in the past six hours. Even close to the lake, where I live, it's already warmer outside than inside—and I had the heat on briefly this morning!
Today the forecast looks hot and humid, before temperatures plunge again Sunday night. Then hot again next weekend. And maybe seasonally appropriate when meteorological summer begins two weeks from today.
Who knows. Welcome to Chicago in spring.
