MESONET TICKER ... MESONET TICKER ... MESONET TICKER ... MESONET TICKER ... July 18, 2014 July 18, 2014 July 18, 2014 July 18, 2014 The coolest July day on record in Oklahoma...July 17, 2014 Pretty simple title that says it all. And a pretty simple (if not inelegant) method to come up with the answer as well. Simply take all the highs and lows from across the state and average them together for yesterday, July 17, and then compare them to all the historical statewide daily averages for July on record. Here are the highs and lows from yesterday. I'll also throw the historical station records on there as well for lowest minimum and maximum temperatures, so you can see if your area broke or came near a record or not. http://ticker.mesonet.org/archive/20140718/july17-lows.png http://ticker.mesonet.org/archive/20140717/july17-record.low-minimums.png http://ticker.mesonet.org/archive/20140718/july17-highs.png http://ticker.mesonet.org/archive/20140716/record-low.tmax-july16.png Onward. Average all those highs and lows together, brute-force style, and you get a statewide average temperature of 63.6 degrees. Now, go back in history and calculate all the same numbers using the same method (in this case, we are using the NWS COOPerative data for the historical comparison...the number usually come out pretty close between the networks). Compare that to the numbers from the historical data archives obtained from the National Climatic Data Center and you find that yesterday was indeed the coolest July day on record for Oklahoma. Here are your top-10 coolest July days on record for Oklahoma. Congrats to July 16, 2014, which came in at #3! 1. 7/17/2014 -- 63.6F 2. 7/12/1953 -- 66.3F 3. 7/16/2014 -- 66.4F 4. 7/05/1972 -- 66.5F 5. 7/21/1970 -- 66.6F 6. 7/05/1915 -- 67.1F 7. 7/03/1924 -- 67.5F 7. 7/26/2004 -- 67.5F 9. 7/04/1924 -- 67.6F 10. 7/10/1996 -- 67.9F 10. 7/14/1990 -- 67.9F 10. 7/23/1947 -- 67.9F Again, we're comparing Mesonet data with the historical COOP data, but the numbers by climate division and statewide usually end up being pretty close. The fact that yesterday blasted the previous coolest day by 2.7 degrees is pretty telling, nonetheless. And historically, we really only went back to the 1910s so we could have a robust number of stations to figure up the averages. There just weren't many observations (or people) before that time. Plenty of records broken at individual station yesterday as well, obviously. OKC broke both its record lowest minimum and maximum temperatures for July 17 with readings of 62 and 68 degrees, respectively. The previous records were 63 degrees from four other years and 80 degrees from 1900 and 1950...again, respectively. Tulsa broke its record lowest maximum temperature yesterday with 68 degrees, well below the previous mark of 82 degrees from 1950 and 1989. It also broke its lowest minimum temperature from this morning with a low of 59 degrees. The previous record was 63 degrees back on July 18, 2009. And, from comparisons we talked about yesterday, the high of 62 degrees recorded at Slapout is tied for the 12th lowest maximum temperature ever recorded in Oklahoma during July. The temperatures will now start to rise again to summer-like values, with 90s forecast statewide as early as Sunday. Expect the humidity to be thick! http://ticker.mesonet.org/archive/20140718/sunday-forecast-highs.png The event ends with some drought-quenching rains across most of the state. Those in the extreme northeast went largely without, and some areas across west central and northwestern Oklahoma just got a bit of wetness. http://ticker.mesonet.org/archive/20140718/event-rain-totals.png Look for changes on next week's U.S. Drought Monitor as we continue to get unusual drought relief through the summer months. Will it continue? Well, stay tuned. I for one miss summer and its 90s (at least...80s will do). Summer is there for a reason. Who wants to just have Spring and Fall? Sprall? Fring? No, come back summer, for a bit at least!
