1:30 p.m. update:
A combination of winter precipitation and commuters leaving Little Rock has caused traffic to back up all over the metro area.
"What we're seeing right now is a lot of folks getting on the road making their way home," Arkansas Highway and Transportation Department spokesman Danny Straessle said. "With high traffic volume and [precipitation] accumulation, all of the arteries in and out of the metro area are going at a snail's pace right now."
Straessle said he hasn't received any reports of jackknifed 18-wheelers or other accidents blocking traffic.
There have been scattered reports of cars sliding off the roads because of snow and ice accumulations over the past 18 hours, Arkansas State Police spokesman Bill Sadler said. There have been no fatalities so far, according to Sadler.
The state Highway and Transportation Department was able to pretreat roads before the second round of snow hit Monday.
Straessle said now salt trucks are loaded and patrolling for any slick spots, and snow plows will be ready to go when snow accumulation hits 1 inch.
Treating the roads and plowing will be difficult with the high volume of traffic, Straessle said.
"Hopefully this wave of exodus from the capital city will die down in the next couple of hours so we can get back to work," Straessle said.
Snow will continue to fall because of another storm coming from Oklahoma, officials with the National Weather Service in Little Rock say.
Meteorologist Tabitha Clarke said the snow should taper off about 6 or 7 p.m. Monday.
Northwest Arkansas will receive some additional snow, but the National Weather Service expects the hardest-hit areas to be central Arkansas and south of Interstate 40, Clarke said.
Clarke said this last round of snow from Oklahoma should be the last bit of winter precipitation for a few days.
Temperatures will get close to freezing Tuesday and should continue warming into Wednesday, Clarke said.
Earlier:
A wintry storm Sunday night into Monday left roadways slick in a large swath of Arkansas and a second round was delivering another blast of frozen precipitation by midday.
The slick conditions — and the threat of more to come — prompted dozens of schools to dismiss early or call off class for the day, including the Little Rock, North Little Rock, Pulaski County Special, Benton and Bryant districts. State offices in Little Rock, meanwhile, were operating on a two-hour delay. A full list of closings is available here.
The Arkansas Department of Highway and Transportation at 10:30 a.m. reported snow on highways north of Mena and ice to the south, ice patches on highways north and west of Little Rock and ice and slush on highways around and south of Forrest City. An updated condition map is available here.
All but northern Arkansas was under some form of winter storm advisory or warning Monday as another system approached, bringing with it the possibility of accumulating snow.
Much of the state, including Little Rock, was under a winter weather advisory through 6 p.m. for light snow that had begun falling late Monday morning and was forecast to continue through the afternoon. The National Weather Service said central and western Arkansas might see 1 to 2 inches of snow while an additional inch on top of that might fall in an area roughly from Danville to Hot Springs to Glenwood to Mena.
The snowfall was expected to reach central Arkansas around 11 a.m.
Parts of southwest Arkansas, meanwhile, were under a winter storm warning because of sleet that the weather service said could total 1/2 inch.
The weather Monday was also causing some problems for fliers at the Bill and Hillary Clinton National Airport, where service between Little Rock and Dallas and Houston was interrupted. Several cancellations were reported on the airport's website.
