...NWS DAMAGE SURVEY FOR 1/10/2020 TORNADO EVENT...

.OVERVIEW...Severe thunderstorms developed into eastern Oklahoma
during the morning of Friday, January 10th, ahead of a strong storm
system that moved into the Southern Plains from the Southern Rockies.
Unseasonably warm and moist air ahead of this system resulted in weak
instability to develop across eastern Oklahoma and northwestern
Arkansas. Strong wind fields and very strong wind shear, both deep-
layer and low-level, combined with this instability, resulted in 
some of the storms through mid afternoon to become supercells. These 
storms produced hail up to golfball size, damaging wind, and a 
tornado. The damage from this tornado will be surveyed by our office 
on Monday. By late afternoon, the storms had evolved into a squall 
line that moved across far eastern Oklahoma and western Arkansas
through the evening. As this squall line moved through northwestern 
Arkansas, it produced damaging wind and a tornado. The damage from 
this tornado was surveyed today by our office, along with Franklin 
County Emergency Management. The details of our survey follow.
