What happened
The episode as NWS SHV wrote it up.
An arctic air mass began to spill southward across Southeast Oklahoma during the evening hours on January 5th, ahead of a shortwave trough that translated east across the Rockies and across Oklahoma/the Red River Valley during the morning hours on January 6th. As a result, areas of light snow developed across much of Oklahoma during the evening of the 5th, and quickly spread east into Eastern Oklahoma and Western Arkansas during the 6th. Temperatures remained in the mid and upper 20s during the daytime hours on the 6th, which resulted in accumulating snow of 1-2 inches across much of McCurtain County Oklahoma. Specifically, 1 inch of snow fell in the Eagletown, Valliant, and Haworth communities, 1.4 inches fell in Battiest, 1.5 inches fell near Broken Bow and Wright City, with 1.8 inches falling in Idabel. These accumulations occurred on grassy surfaces as well as bridges, overpasses, and some roadways, resulting in hazardous travel conditions.

.AVIATION...
For the ArkLaTex, an Arctic air mass is crossing I-20. As the
cold air deepens, our current VFR/MVFR will likely persist. N
wind 10-20KTS on sfc and aloft to 5kft, then back to W w/ some
good FL speeds; 100KTS near FL300. A short wave is nearing the
OK/TX panhandles. Two layers of dry air aloft attm and looking
good, but as the wave approaches, moisture will fill the column w/
snow overnight and Fri for many terminals. The -sn may briefly
restrict vsby to 3SM at KTXK, but keeping 6SM in -SN elsewhere.
Icing aloft perhaps biggest concern for all as moisture scours.
