A light winter storm will be over OU today.

Beginning with rain, temperatures will drop and winter precipitation should start falling in the area, said Ty Judd, meteorologist at the National Weather Center on campus.

“We should be above freezing until around noon,” Judd said. “Then the rain will start to change over to snow, but it may melt when it hits the ground.”

Judd said the main effect will take place at night when temperatures will drop into the low 20s and the melted precipitation will refreeze on roads and other surfaces.

“It will most likely be a slush-like accumulation on the road until it refreezes at night,” Judd said. “It doesn’t look like there will be any large accumulations for Norman. Most of the accumulations will take place in the northwestern part of the state. The most we can expect is a couple of inches of snow.”

Judd said the worst part of the storm OU will experience is the dramatic fall in temperatures.

“It could get down near 18 degrees,” he said.

Judd said the National Weather Center also is watching another storm that will be approaching the area around Thursday.

“It could be cold enough for us to get a winter mix, but [the storm] is just too far out from us to make any solid determinations,” Judd said.
