The official 1991-2020 OKC normals are also about a degree cooler than what was actually recorded during that timeframe. I will never understand the reasoning behind that and it's going to annoy me for the next 7 years until the 2001-2030 normals are released lol.

Anyways, it looks like we could make it until the middle third of June before hitting 90 degrees, which I'll take anytime. We usually average about three 90 degree days in May but we didn't get any this year. We usually average about 14 in June and it will take consistent heat in the latter half of the month to get there this year (always possible given that this is OKC, but it would represent a major pattern change from what we've been seeing over the last few weeks).
