RECORD EVENT REPORT NATIONAL WEATHER SERVICE FORT WORTH TX 140 AM CDT TUE JUL 16 2013 ...RECORD LOW MAXIMUM TEMPERATURE SET AT DALLAS FORT WORTH... THE HIGH TEMPERATURE AT DALLAS FORT WORTH INTERNATIONAL AIRPORT ON MONDAY JULY 15 WAS 74 DEGREES. THIS BREAKS THE PREVIOUS RECORD LOW MAXIMUM TEMPERATURE ON THAT DATE OF 79 DEGREES...WHICH WAS SET IN 1900.
It is interesting that, while it was ninety up in Montreal at seven o’clock in the evening yesterday, in Dallas they were cool.
We are not talking down in Houston, where you can get a southern version of a sea breeze, but up north in Dallas, where in July you tend to think of cactus, and a cow’s skull bleached white in blistering desert heat.
Nor are we talking about a brief spell of coolness after a thunderstorm, as the hailstones melt in the puddles. A thunderstorm would be preceded by a hot day, and the day’s high temperature might be over ninety, before the thunder.
No, we are talking about an entire day, sunrise to sunset, where the temperature never got above seventy-four. In July!
This did not edge out the old record, from back in the year 1900, 112 years ago. It crushed it. The old record was 79 degrees. Practically eighty. However yesterday it was in the low seventies all day, which is “practically in the sixties.”
This weather is due to a cool upper air low pressure area which has been pushed to the west by the Bermuda High’s growth. It started out as a large pocket of cool air in a trough digging into the east, but the trough “split.” Part of it retreated back to the north and rippled away to the east, but the southern part was cut off, and in a sense became something like a tropical wave in the Trade Winds, moving east to west.
(Think of a northern trough as a triangle, with its point down, moving west to east in the Westerlies, while a tropical wave is a triangle with its point up, moving east to west in the Easterly Trade Winds. A “trough split” is an exchange between the two.)
The Alarmists need some help at this point. They spoke of “Global Warming,” and it simply fools no one to change the terminology to “Climate Change” at this late date. While ninety degrees in Montreal is not unheard of in July, seventy-four for a high in Dallas is unheard of, in July. You call that warming!!!?
Therefore, out of the goodness of my heart, I will lend Alarmists a hand. What they should do is state the coolness in Dallas is proof of warming, because it demonstrates that the Trade Winds are coming further north, and the climate of Dallas is no longer in the reach of hot summer Westerlies, which have been driven north by the “increasing heat.”
The reason I can be so helpful is because I try to stay one step ahead of Alarmists. I try to figure out what excuse they will dream up next. (This may be a side effect of dealing with so many small children’s excuses, at the Childcare at our farm.) (It also may be a side effect of once needing to dream up so many excuses for undone homework, when I was a schoolboy.) In any case, I am often several steps ahead of Alarmists and their excuses for the failure of their theory.
In this particular case one needs to focus on the fact that, even if you consider the feature that passed over Dallas an “Easterly Wave,” it is a very cold wave, compared to other Easterly Waves. It does not fit in with the idea that there should be a “hot spot” in the upper atmosphere down in the tropics. In fact, with easterly waves this cold, it is going to darn hard to melt the icecaps and see the rising oceans boil.
In conclusion, if you add the Dallas coolness into the totality of the Earth’s temperatures, you come up with an average temperature for the planet that is taking a plunge from a short-term peak it achieved in June. In fact, according to Ryan Maue’s daily calculations of the earth’s average temperature at a couple meters above the surface, temperatures world-wide have fallen a full half degree in only two weeks.
I find thinking of this cooling is a conciliation, during an East Coast heatwave where even sitting here typing has a sheen of sweat beading on my brow.
