Ft. Supply Residents Tired of the Cold Weather!
Just got word from the folks across the hall at the Norman National Weather
Service forecast office that Ft. Supply cooperative observer station reached a
low temperature of 40.7 degrees. Rounding that up to 41 degrees doesn't make it
seem any warmer, especially for August 25. The nearest Mesonet station at
Woodward only got down to a relatively warm 50 degrees, but the Woodward
meteogram tells the story of what occurred at Ft. Supply. Very light northerly
winds and clear skies allowed density and radiational cooling to prevail, and
the temperature plummeted at the observer's location.

Historically, that is the coldest temperature ever recorded in Ft. Supply during
August, besting the previous record low for the month of 47 degrees, set on
August 29, 1988. It shatters the previous record for Ft. Supply on the 25th
itself by 10 degrees with the previous record being 51 degrees set back in 1966.
Data from Ft. Supply began in 1940. The reading also becomes the 5th-lowest
temperature ever recorded in Oklahoma during August (tied with 2 others):
39 MARLOW 1 WSW 8/24/1923
39 OKMULGEE WATER WORKS 8/24/1967
40 BOISE CITY 2 E 8/28/1964
40 JEFFERSON 8/10/1903
41 FT. SUPPLY 8/25/2010
41 JEFFERSON 8/31/1915
41 SOUTH GRAND LA KE 8/21/1950
42 ALVA 1 ENE 8/29/1988
43 CHICKASHA 8/31/1915
43 PAWHUSKA 8/31/1915
43 RALSTON 8/29/1988
43 STILLWATER 2 W 8/31/1915
I find the 40-degree reading at Jefferson to be highly suspect, although there
was a 42 at Woodward that day, and a 53 at Newkirk. The surrounding stations
were all in the 60s. That data stands, however, until we can do a bit more
investigating.

At any rate, nothing changes the fact that there was some really cool weather
in the northwest last night. And I'm not talking Fonzie-cool, but brrrrr!-cool.
An early preview of coming attractions.
