Extremely 2019

It seems like it was just a year ago that we were posting this Mesonet extremes figure. Oh wait, it was. As we sit bleary-eyed wondering how another year could have passed so quickly, the true wonder remains exactly how Oklahoma continues to produce such exhilarating environmental extremes. And remember, those are just the parameters that we measure with the instruments of the Oklahoma Mesonet (or calculate from those measurements). That says nothing that even in 2019's last week, we increased our annual record tornado total from 146 to however many tornadoes struck eastern Oklahoma on Dec. 28. At least one has been confirmed by the Tulsa NWS office, so we'll put that record at 147 for now.
There were some equally momentous amounts from the Mesonet. Take the 81.64" of rainfall at Miami. No, please. Hey, I ain't no Henny Youngman...these are the jokes you get, folks! That rainfall total is 37.4" above normal. Let me repeat. Okay, I won't. But that's an incredible amount of rainfall to hit the state of Oklahoma. That's 2015 Godzilla El Nino territory right there, WITHOUT the aid of the Godzilla El Nino. That's the highest of any official reporting station in Oklahoma. There was a CoCoRaHS site at Jay that recorded 82.79", so obviously the totals in far northeast Oklahoma shattered the previous annual records for those locations. Still far behind the current state record holder, the COOP site at Daisy with 89.69", but very impressive nonetheless. Simply put, one of the highest annual rainfall totals ever recorded in the state of Oklahoma.

Then there's the not-so-fun stuff, like the heat index at Bixby on August 26 of 118 degrees. And the 108 degrees at Hooker on August 19 for the highest actual air temperature recorded during the year. Both somewhat tame by Oklahoma standards, but if you're at those locations experiencing those extremes, you aren't having a fun day.

But that's a might sight better than the -4 degrees at Eva on November 12, or trick-or-treating in sub-freezing weather like out at Kenton on Halloween this year. The reading of zero degrees is the lowest temperature ever recorded in Oklahoma in October, or that early in the cool season. Rather momentous.

The 31 days at or above 100 degrees for Hollis again seems almost tame by our standards, but the 94.2 mph wind gust at Marshall on May 20 (a date with worse connotations) would blow your eyeballs out regardless of the location.

So we're extremely happy to be able to present the Mesonet extremes graphic for yet another year. And we anxiously await the amazing meteorological wonders our 120 lonely sentinels -- the Oklahoma Mesonet sites -- will observe during 2020. Some with trepidation, some with bated breath, always with anticipation, but also with an understanding that this is the weather we are accustomed to in Oklahoma...a land of weather extremes.
