Officially A Heatwave; And It's An Early One

In our area, we refer to a heat wave as three straight days where the mercury officially reaches 90 or above. Some spots did reach 90 for the third day in a row today, which marks the earliest we've seen a heatwave since 1996.

Heatwaves are sometimes hard to come by. In fact, 7 of the last 20 years did not have one by definition. Check out the summary of the heat waves since 1977 compiled by weather intern Jacqueline Layer.
