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.


Key Messages:

  • Winter Storm Warning in effect until Monday for the entire forecast area
  • Snow accumulations 3 to 7 inches with possible higher snow drifts
  • Temps plunging to near all-time record cold temps on Tuesday with lows near 0°F
  • Windchill values 10 to 20 below zero
  • Hypothermia and frostbite can set in quickly in this type of dangerous/severe cold
  • This will be the coldest in 30 plus years!
  • This will be a prolonged cold snap
  • Temps will not get above freezing until next Saturday
  • Blowing and drifting snow
  • Near Blizzard conditions at times Sunday night
  • Whiteout conditions possible Sunday night

  • Another major winter storm expected Tuesday night into Thursday
  • Governor Abbott has declared all of Texas as a disaster area

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.


September 2020 turned out to be the 13th coolest September on record for DFW with an average monthly temperature of 75°F. We were 3.3°F below normal for the month. The coolest temperature of 50°F was recorded on September 29th, only 10°F above the all-time coldest monthly low of 40°F. Pretty impressive considering that only last year, September 2019, was the all-time hottest September on record for DFW. Weather records date back 122 years to September 1898 for the DFW area.


DFW Airport shattered the high temperature record for April 8, 2020. The high temperature of 97°F breaks the old record high of 93°F set in 1991.

In addition, the low temperature this morning, April 9, 2020, was 71°F breaking the old low maximum temperature of 70°F set in 2001.


The coldest Halloween in 26 years just occurred at DFW. It was 1993 when we had a cold blast of similar magnitude to the one that just happened. In fact, the cold blast of 1993 was actually a little colder and produced snow flurries on the 29th. On Halloween 1993, we reached a low of 29°F. This year we missed that record by one degree with the low on Halloween reaching 30°F. We tied the record low of 31°F set in 1906 for November 1st. 2019 was only one of five years where we had back-to-back consecutive freezes so early in the season. Other years with back-to-back freezes so early in the season include, 1913, 1925, 1957, 1993, and 2019. October 2019 ended up being 2 degrees below normal for the month. This joins the myriad of cooler than normal months of 2019, with September 2019 being the notable exception because it was the hottest September on record.
