Swells and high surf from both Imelda and Humberto are expected to bring dangerous marine and rip current conditions to the east coast of Florida and Georgia today, spreading north along much of the east coast of the U.S. this week. Heavy rainfall north and west of Imelda falling across coastal Florida and Georgia into the Carolinas could cause isolated flash and urban flooding through Tuesday. Read More >
Overview
A historic outbreak of arctic air resulted in record breaking cold temperatures that lasted almost two weeks for some locations in the combined Texas and Oklahoma Panhandles. The cold air moved over the northeastern combined Panhandles as early as Feb 8th, and spread southwest through Feb 12th, engulfing most of the southern plains by Feb 13th. The frigid arctic air would put a strain on area power grids, resulting in rotating blackouts for some locations (this was much worse for other portions of Texas ). In addition, two storm systems interacted with the arctic air to produce several inches of snow, not only across the Panhandles but across most of the Great Plains, including almost the entire state of Texas and surrounding states. Amarillo ended up with 5.0" on Feb 14th, and 7.4" on Feb 16th. Periods of flurries and freezing fog also occurred mainly in the overnight and morning periods almost each day Feb 12th through Feb 18th.
Snow Round 1: February 14th
On February 14th, an upper level storm system crossed the southern plains which was entrenched in arctic air. The system added lift and moisture to a very cold air mass, which helped produce several inches of snow all across the Panhandles. Most locations saw around 3 to 5 inches, with some outliers seeing more/less. Breezy northeast winds resulted in blowing snow and made measuring snowfall very difficult. Some snow drifts were 16 to 20 inches deep. Snow ratios were around 15:1 to 20:1.

Record Cold
While much of the area was below freezing for over a week, the coldest days were February 14th - February 16th. On the 14th, the daytime high temperature in Amarillo was only 3 degrees. The frigid temperatures combined with a 15 to 25 mph wind resulted in wind chill values around -15 to -25 degrees (some locations even hit 30 below zero). On the night of the 14th into the morning hours on the 15th, winds let up some as the arctic high pressure settled over the area. The ambient temperatures bottomed out that night, with Amarillo falling to 11 below zero. The coldest location fell to 22 below zero (Boise City, OK). In the Texas Panhandle, the coldest was 20 below zero at Palo Duro Reservoir. While not quite as cold, temperatures still fell below zero once again on the night of the 15th into the early morning hours on the 16th.

Snow Round 2: February 16th
Another storm system came across the area on February 16th. This one was a bit more challenging to forecast due to uncertainty with a very narrow band of snow. This band ended up forming over I-40, and produced anywhere from 5 to 9 inches from Vega to Shamrock. NWS Amarillo measured 7.4 inches total snow for this event.
Snow will continue to move to the east northeast across the southern Texas Panhandle. Most of the snow will stay along and south of the Canadian River #phwx #okwx #txwx pic.twitter.com/LDfcMkQjIQ

Climate Fun Facts
Climate Overview
Amarillo, TX had a warm start to February of 2021, along with other areas in the combined Oklahoma and Texas Panhandles, with the first 7 days making it to a high temperature of at least 50 degrees Fahrenheit. In fact, on the third day Amarillo reached a high of 79º F. Overnight lows were only making it down into the 20s through about day 8 of the month.
February 7th, a strong arctic air mass moved into the northeastern combined Panhandles. Beaver, OK would last see temperatures above freezing on February 6th before going into a prolonged freeze event. A cold front moved into the Panhandles bisecting the southwest from the northeast creating quite the temperature difference. Around 2 P.M. CST Sunday the 7th, Beaver, OK was sitting at 26 º F, while Hereford, TX had warmed to 66 º F. Borger, TX which is about halfway between Beaver and Hereford, was at 51 º F by this time. Perryton, TX which is approximately 30 miles to the southwest of Beaver, OK was 34 º F by 2 P.M. The warm air in the southwest would begin to battle over the Panhandles with the cold arctic air to the northeast for several days.
Behind the cold front remained low clouds and moisture that created freezing fog and freezing drizzle across the area starting on the 7th in the northeast but expand as the cold air moved southeast during the hours of darkness. The freezing fog and drizzle created slick driving surfaces and poor visibility to motorists, but it also made for some beautiful winter scenery. Guymon, OK along with much of the northeast half of the combined Panhandles would be stuck under these low clouds and fog deck for days. While Guymon, OK got to 52 on the 7th it only reached a high of 25 º F on Monday the 8th. This was the start of 11 consecutive days that Guymon would be below freezing.
Each day between the 7th and the 11th the warm air would battle over the southwestern combined Panhandles. Those areas that stayed to the northeast of the front would be stuck under overcast skies and sometimes when the fog lifted would get flurries. The cold air won over Amarillo on the 10th with Amarillo’s high temperature only getting to 24º F. The next day on the 11th the warm air took over parts of Amarillo allowing the high to barely squeak above freezing with a high of 33 º F. This would be the last day Amarillo would be above freezing for an extended period. The evening of the 11th the cold air mass finally started taking over much of the southern plains. In fact, it had started to take over the entire state of Texas.
By the 13th, most of the Southern Plains to include a good portion of Texas would be preparing for a strong storm system that would combine moisture with extreme cold to create a winter storm across several thousand miles. Snow began to fall on the evening of the 13th, with more snow and even colder temperatures taking over on Valentine’s Day. Amarillo officially got 0.9 inches of snow on the 13th with an additional 4.1 inches falling on Valentine’s Day. Valentine’s day ended up being so cold that daytime temperatures would not make it out of the single digits across much of the combined Panhandles.
To show how #cold we've been in #Amarillo, #Texas compared to climatology and records, here's a graph showing where we have stood lately. The brown shading is considered the "average" day, and we have been complete below that since February 12th. #ArcticBlast2021 pic.twitter.com/eSfHtX94BK
