DFW set a record high yesterday, July 20, 2022 and also tied the maximum low temperature record for that date. DFW also set a record high temperature on July 19, 2022 and also tied the maximum low temperature record for that date. DFW also tied the all-time maximum low temperature record for July 18, 2022 while also breaking the daily record for that date.

The temperature yesterday reached a high of 109°F, for the third consecutive day, which broke the old record of 108°F set in 2018. DFW tied the low temperature maximum of 82°F set in 1954.

The temperature on July 19, 2022 reached a high of 109°F which broke the old record of 108°F set in 2018. DFW tied the low temperature maximum of 84°F set in 1980.

The low temperature on July 18, 2022 was only 86°F. This tied the all-time lowest maximum low temperature ever recorded at DFW set several times, but most recently in 2018. This also broke the daily maximum low temperature record of 83°F set in 2018.

DFW temperature records are observed at Dallas/Fort Worth Interantional Airport weather station, station ID, KDFW.


Yesterday the high temperature was 103°F at DFW Airport. This tied the record yesterday set back in 1911. It also marks the first time this summer we officially hit 100°F. This is the hottest DFW has been in nearly two years. You have to go all the way back to August 29, 2020 when the mercury hit 106°F.

In addition, yesterday DFW set a new maximum low temperature of 79°F. The old record was 78°F set in 2018.

The intese heat wave we have been experiencing is going to continue through tomorrow. A record high is likely to be set again today as temperatures across the area are expected to climb to or exceed 105°F. A Heat Advisory remains in effect for the entire area.


December 2021 has gone down in the records as the hottest December on record for DFW by a wide margin. The average temperature was a whopping 13°F degrees above normal. That is 7 plus degrees hotter than the old record hottest December set in 1933. In fact, December 2021 was so hot compared to averages that no other calendar month in our weather history has an average temperatue of 13 degrees above normal. December 2021 also produced the hottest Christmas on record of 82°F. The old record was 80°F set in 2016. The hottest temperature of the month was 83°F on December 10th. The coldest temperature was 32°F on December 12th. That is the first and only freeze at DFW Airport so far this winter season. The top 5 hottest Decembers for DFW are:

  1. December 2021
  2. December 1933
  3. December 2015
  4. December 1970
  5. December 1965


Yesterday, the temperature officially reached 100°F at DFW Airport for the first time in 2021. This is pretty late in the year for a first 100 degree day, but not as late as the latest which was none in 1906 and 1973. The average first 100 degree day is usually on or around July 1st. We average 20 days a calendar year of 100 degrees or greater. The hottest temperature ever recorded at DFW is 113°F on June 26th and 27th of 1980, our hottest summer on record. In fact, temperatures of 110°F or greater are exceedingly rare and have only occurred 12 times in our history. Five of those occurrences were during the summer of 1980. We have only hit 110°F or greater twice during this century, once in 2000 and once in 2011.

The heat will continue the rest of this week and into next, but there are long range signs that the heat will be somewhat transient, and there may be a cool down and more rain headed our way. We will have to see how that plays out. Regardless of the heat this week, it still looks like the temperature anomalies will be too great to overcome so that July will be a slightly below normal month.


The severe cold spell that we had a couple of weeks ago had temperature anomalies so great that it made February the fifth coldest on record at DFW. In addition, prior to that, the 2020-2021 winter season was averaging 1.7°F above normal, and the cold spell turned an above normal winter below normal. Now the winter average is 1.8°F below normal.

The mean average temperature for February 2021 at DFW was 41.1°F a whopping 8.9°F below normal. The top five coldest Februarys in DFW history are as follows:

  1. February 1905
  2. February 1978
  3. February 1899
  4. February 1929
  5. February 2021


The official low this morning was -2°F. That is 2 degrees below zero. This shatters the daily record low for Feb 16th of 12°F set in 1903. This is 42 degrees below the normal low of 40°F for this date. The last time DFW dropped below zero was on December 23, 1989, and the temperature dropped to 1 below. You have to go all the way back to January 31, 1949 to get to the last time we were 2 below zero, a whopping 72 years ago. This makes the 5th time the mercury has dropped below zero at DFW. The other times were:

February 12, 1899: -8°F (all time coldest temperature at DFW)
January 18, 1930: -1°F
January 31, 1949: -2°F
December 23, 1989: -1°F
February 16, 2021: -2°F

In addition, the high of 18°F recorded at DFW today, also broke the daily record high temperature for Feb 16th. The previous record was 21°F also set in 1903.


A new record low temperature and a new record low max temperature was observed at DFW Airport on February 15, 2021. A low of 4°F breaks the old record of 15°F set in 1909. A high of 14°F breaks the old low max high temperature for that date of 31°F set in 1909. It is also the third coldest high temperature in DFW history. The record is 12°F set on February 12, 1899.


A new daily low temperature of 9°F was set yesterday replacing the old record of 15°F set in 1936.

A new daily maximum low high temperature of 22°F was set yesterday replacing the old record of 27°F set in 1951.

A new daily maximum snow record of 4.00 inches was set replacing the old record of 3.00 inches set in 1951.

Yesterday’s snow officially breaks the near 6-year long snow drought. The longest in DFW history of not receiving significant snowfall.

Yesterday’s temperature of 9°F also ends the 25 year long streak of not ever falling below 10°F. The longest in DFW history. Climatology says we should be getting below 10°F every 5 years.

We will have official snow totals a bit a later.

Folks—we cannot stress this enough—you are about to witness a historic winter weather event. It cannot possibly get any more severe than this. This will rival the great cold air outbreaks of December 1989, December 1983, January 1930, and yes the king of them all February 1899. This will be a protracted cold snap. DFW Airport has already spent the last 72 hours below freezing and counting. We are not expected to rise above freezing until next Saturday afternoon at the earliest. This will make for the longest stretch of subfreezing conditions at DFW since December 1983. Major agricultural and infrastructure damage will result from such cold. Governor Abbott has issued a disaster declaration for all of the state of Texas. You have narrow window today to do final preparations before things deteriorate rapidly.

Areas of freezing drizzle this morning are coating surfaces, including roadways with a thin glaze of ice. Motorists are urged to exercise extreme caution this morning if traveling. The freezing drizzle should end this afternoon, with a lull before the next precipitation starts this evening as the main shortwave trough approaches Texas. Areas of freezing drizzle and sleet will begin tonight and ramp up significantly after sunrise on Sunday. The ground surface is frozen after 72 hours and going on 96 hours of subfreezing temperatures at DFW Airport. This means precipitation will stick instantly as it falls to the ground causing roads to deteriorate rapidly on onset. Snow will become widespread and heavy Sunday night. Because of the powdery nature of the snow, much like you would find at a ski resort, it will easily be blown around. Winds are expected to be near 30 mph at times causing blowing and drifting of snow and near blizzard conditions at times. Visibilities will be reduced to near 0 at times causing whiteout conditions. It is strongly recommended that no one travel during this time. Snow ratios may be 15:1 to 20:1 as opposed to our typical 10:1 because of the extreme cold. Total accumulations expected are 3 to 7 inches. Snow drifts could easily exceed 7 inches. It must be stressed that not everyone will see 7 inches and some places could exceed 7 inches, and some places could be a little less than 3 inches. However, everyone should see at least 2 inches of snow.

On top of all of this a frigid Arctic airmass will continue to be advected south. We are dealing with, as stated above, the coldest weather DFW has seen in 30+ years. Temperatures will be close to 0°F by Tuesday morning. Breaking the daily low temperature record and getting near the all-time low temperature record for DFW of -8°F set on February 12, 1899, though that should be safe. We have already gone 72 hours at DFW Airport below freezing. We are not expected to rise above freezing until next Saturday afternoon at the earliest. This will be the second longest stretch of subfreezing conditions ever recorded. The record is December 1983 with 12 days of subfreezing conditions. This is life-threatening cold we are talking about. Frostbite and hypothermia can set in quickly in this type of cold. Hard Freeze Warnings and Wind Chill Warnings will likely be necessary.

Precautions should be completed today to protect people, pets, livestock, and exposed pipes. This type of prolonged cold will cause extensive damage to infrastructure and agriculture locally and across the state. Pipes can freeze and burst in such extreme cold.


A massive Arctic airmass has been building in Canada and has been the focus for the last several days in the weather community. The question was when and if it would move south. The models have come into nearly unanimous agreement this air will move south this week. The worst and core of the cold may move over Texas this weekend bringing some of the coldest temperatures in years to DFW (at least since January 2018, but maybe longer if the models are to be believed). A cursory glance shows most of the central and western Canadian prairies well below zero (-40°F+ in some areas). With an upper low tightening up in the Great Lakes, the flow around this will be enough to give the airmass the nudge to move south rapidly in waves by the weekend.

The leading edge of this massive Arctic air is actually going to move into the area tomorrow, kind of like pancake batter, moving south based on its own density. This is a very shallow leading edge of the Arctic airmass and really not all that cold yet. Our temperatures will gradually turn colder throughout the week with the coldest arriving Friday evening and may last into early next week.

Severe cold is defined at DFW as being a low temperature at or below 10°F or a high at or below 20°F. This is definitely on the table with several models showing that kind of cold. While we are not confident, yet, in cold getting that extreme, we are confident it will turn very, very cold. Temps will likely drop into the teens, if not colder, and wind chills may dip below zero at times. This is also likely to be a protracted cold spell much like Super Bowl week of February 2011. We could see more than a day of subfreezing temperatures.

What is not quite as clear is the prospects of precipitation in the cold air. Experience tells us moisture may be hard to realize in such deep intrusions of cold air. However, it does not take much lift or moisture to cause it to precipitate in that kind of cold air, and their will be some perturbations that move across the cold air. Of course any precipitation in this cold would be frozen and could potentially impact travel. More on this as we get a better handle on the latest data.

Residents of DFW should prepare now to insulate exposed outdoor pipes from the cold. If this cold is realized to its full potential, it would be more than enough to freeze and burst pipes that are exposed.
