Weather forecasters around the area know they blew it last weekend — a predicted nine- to 13-inch snowfall ended up bringing only three inches to Lawrence.

But Ross Janssen, 6News meteorologist, says he’s much more confident of his forecast for Wednesday’s winter storm: three to six inches by Thursday afternoon.

The reasons? No sleet. And no rain.

“Our confidence with this storm will be higher because we don’t have to concern ourselves for when the precipitation is going to change forms,” he said.

“It looks like any chance for there to be any sleet and rain will be down in eastern Oklahoma and far southern Missouri,” he said.

So that mean all of the precipitation will be in the form of flakes, he said.

Clouds are expected to start increasing later on tonight, with the temperature dropping to a low of 16 degrees, he said.

Janssen is expecting the snow to hold off until mid-afternoon.

“I’m kind of thinking that snow will start sometime about 4 p.m.,” he said. “We’ll have a southeast wind 10 to 20. And it shouldn’t be as warm — about 30 degrees tomorrow afternoon.”

Wednesday night will be the heaviest snow, with reduced visibility because of blowing snow, he said.

“We’ll have winds about 25 mph from our east and 25 will be our overnight low,” he said.

The snow will continue Thursday for much of the morning hours, but will taper off toward late morning, he said.

“Total accumulation right now, I think we’re going to be about three to six inches by Thursday afternoon.

The drifting may cause problems with roads on Thursday morning, he said.

“I think we’re goiing to notice more wind with this particular storm. There could be enough wind with drifting to close the schools,” he said.
