DALLAS,Texas - Just in time for 2010 NBA All-Star Weekend, Dallas got its largest snow day ever as 9.8 inches of snow was recorded to have fallen on Dallas/Fort Worh International Airport as of 10:00pm Dallas time and it's still coming down. That is the most snow in Dallas ever, at least since it started collecting weather data 111 years ago. The previous record was 7.8 inches in one day set in 1917 and again in 1964. This all coming just as 2010 NBA All-Star Weekend events began today. The weather has caused havoc on Dallas roads as well as shut down Dallas/Fort Worth International Airport, just as tens of thousands of fans and players were scheduled to come in.
