The year ended with a complex situation over the middle of the country. A powerful storm system in the southern Plains brought a variety of precipitation types depending on the temperature during the last two days of 2020.

 

There was a lot going on in the middle of the country ahead of a storm system (ā€œLā€) in south Texas. There was ice/snow in cold air north/west of the system, severe weather in warm air along the Gulf Coast, and heavy rain in-between.

Temperatures were in the 60s/70s along the Gulf Coast (it felt like spring), and there was a potential of severe thunderstorms and isolated tornadoes. This did not turn into much, with isolated weak tornado damage around Corsicana, TX on the 30th, and twenty to thirty miles north and west of Macon, GA on January 1st. From west Texas to central Oklahoma, northern Missouri, and eastward to Ohio, it was cold enough for snow and ice.

 

Seventy two hour snow and ice accumulations as of 600 am CST 01/02/2020.

Two to more than six inch snow accumulations were common from Midland, TX to Oklahoma City, OK and Kansas City, MO. In parts of west Texas, including Big Spring, TX, there was more than a foot of powder. It was enough to shut down Interstates 10 and 20 temporarily. Hundreds of vehicles were stranded. Ice was a tenth to a half inch thick on exposed objects from Wichita, KS to Springfield, MO, St. Louis, MO, and Indianapolis, IN.

 

Winter weather, severe weather, and flood headlines were posted across the central United States at 1130 am CST on 12/31/2020.

In Arkansas, it was mostly rain given temperatures were above freezing in most areas. There were several inches of rain in central and southern sections of the state, which is where precipitation lingered the longest.

 

Simulated radar showed a seemingly nonstop stream of mostly rain into Arkansas in the thirty hour period ending at 300 am CST on 01/01/2021.

For a time (late on the 30th and through the morning of the 31st), drier air spread into the northern counties, and nothing fell from the clouds. This was the most rain in awhile after a bone dry November, and drier than normal conditions for much of the region in December.

 

Temperatures at 900 pm CST on 12/31/2020. Readings were around freezing toward the Missouri border.

As moisture built back to the north during the evening of the 31st, there were some issues with freezing rain toward the Missouri border. Temperatures at Harrison (Boone County) and Mountain Home (Baxter County) were around 32 degrees, and these locations picked up a thin glaze of ice. It was a touch colder in the higher elevations of the Ozark Mountains, and ice was more significant. Quarter to half inch ice accruals were reported at Compton, Cowell, west of Vendor, and at Western Grove (all in Newton County). Accruals from a tenth to quarter inch were reported near Beaver (Carroll County), Gateway (Benton County), and Kingston (Madison County),
