ORIGINAL STORY: The National Weather Service raised its prediction for St. Louis area snowfall late Friday morning, saying that 8 to 12 inches could fall in areas along Interstate 70 in Missouri and Interstate 55 in Illinois. The area had already been bracing for a "major winter storm," in the words of the weather service.
Kevin Deitsch, a meteorologist with the National Weather Service offices in Weldon Spring, said it could be the biggest snowfall since 2014 and warned of an evening commute that could be "severely impacted" in a morning news conference, before the forecast was revised again.
"If you have the opportunity to leave work or school early we suggest you do so," Deitsch said.
Deitsch said the precipitation is expected to start as sleet mid-day Friday, turn to snow and increase about 3 p.m. in the St. Louis area. That represents an earlier arrival time than had been predicted in recent days. The weather service also said that a layer of warm air could affect the balance between mostly snow and a wintry mix, and the resulting total snowfall.
By 1 p.m., people living in Wildwood, O'Fallon, Mo., and Brentwood all reported snow or sleet was falling. The National Weather Service said the snow could also be accompanied by around 1/3 of an inch of sleet and a light glaze of ice in central, east central and southeast Missouri and the Metro East.
A winter storm warning is in effect from 9 a.m. Friday through midnight Saturday, when the snowfall is expected to taper off.
