Summary of winter storm on March 13-14 1999:A powerful upper level storm system moving eastward along the Red River valley brought one of the top winter storms on record to the area. After spending much of March 13 in a cold rain, cold air associated with the upper system finally moved firmly enough into the area to cause a gradual changeover to snow around 3 PM. The heaviest snowfall amounts were generally in the northeast corner of Oklahoma, although a snow "burst" associated with thunder and lightning over Creek County caused very high amounts of snow there as well. The snow quickly ended around sunrise of March 14, and even the heaviest snow had melted off by the end of the day on March 15.The snow burst in Creek County caused numerous traffic accidents along I-44 through Creek County, and the interstate had to be closed. Several churches in Bristow opened their doors to a total of 450 stranded motorists, while other motorists became stranded in their cars. The weight of the snow caused a carport to collapse in Drumright, damaging a truck underneath.The heavy wet snow weighted down and broke numerous trees and tree limbs throughout northeast Oklahoma. Trees falling onto power lines caused scattered power outages throughout the area. Eight thousand electrical customers in Tulsa lost their electricity, while 2,300 power customers around Grove suffered power outages. Vinita was one of the hardest-hit communities in terms of downed trees and power outages.The following is a list of snowfall amounts from March 13-14: Miami...15", Bristow...14", Vinita...12+", Jay...10-12", Sapulpa...9-10", Pawnee...9", Bartlesville...8", Pawhuska...6-8", Claremore...6-8", Nowata...7", Hominy...6-7", NWS Tulsa (Northeast Tulsa)...6.2", Stilwell...6", Pryor...4-6", Okmulgee...3-5", Wagoner...3-5", Tahlequah...4" and Muskogee...2-3".
