Local Weather History For December 24th...
The Christmas Eve Blizzard of 2009 was a memorable event for most
Oklahomans. A Blizzard Warning was issued for the storm system, which
is a rare occurrence for our state. This storm set snowfall records
in Oklahoma City and Wichita Falls for having the most snow ever
recorded in a single day. Most locations received anywhere from 1 to
7 inches, with 8 to 14 inches reported in Oklahoma City and Wichita
Falls. The event began with rain that quickly changed over to sleet
and then snow with widespread blizzard conditions. Visibilities were
less than 100 feet for several hours and winds built snow drifts at
least three-feet deep. Hundreds of vehicles were stranded as travel
became nearly impossible. Most major highways and interstates were
shut down, and the National Guard was sent in to rescue stranded
travelers from their vehicles. Unfortunately, there were nine
fatalities with hundreds of injuries.
