DFW Freezing Weather Information

What kind of weather will we have this winter? The Old Farmer’s Almanac says the following about the upcoming Texas/Oklahoma Region for winter of 2021/2022: “Winter will be colder than normal, especially in the south, with the coldest periods in mid to late November, mid and late December, and early and late January. Precipitation will be below normal in the north and above normal in the south. Snowfall will be near normal, with the best chances for snow in early and late January, mainly in the north.”
I would like to comment on their prediction from last winter (2020/2021), which was: “Temperamental! Wild swings from mild to tranquil to cold & wintry.” That sounds about right, as we all remember mid- February of 2021: some of the coldest weather that we have ever experienced (-1), freezing weather for many consecutive hours, and unreliable electricity—which is a bad combination for swimming pool equipment.
With that being said, we will not actually know what kind of winter we will have until it is over. Following is some weather information to help get you in the right frame of mind:

What can really be difficult on pool equipment is consecutive number of hours below freezing—the record by a long shot is 295 consecutive hours between December 18-30, 1983. We would have surpassed this record last winter had it not been for a few hours above freezing, which was sandwiched by extremely low temperatures.
