4:35 p.m. update
Winter weather advisories that had been in effect earlier Sunday have expired, and the Arkansas Department of Transportation reported after 4 p.m. that all primary routes in the state had been cleared of snow and ice.
But forecasters said that more wintry precipitation was possible for a large swath of the state on Monday.
On Sunday, a number of locations in northern Arkansas saw half an inch to 2 inches of snowfall. Omaha in northern Boone County got 3.5 inches.
The wintry blast caused some problems on Arkansas highways. Multiple wrecks were reported on Interstate 40 in Johnson County, and the westbound lanes were shut completely for a time.
In southern Arkansas, a winter storm watch was set for Little River, Hempstead, Nevada, Miller, Lafayette, Columbia and Union counties. The watch noted freezing rain and sleet on Monday night is expected to quickly shift to snowfall with some areas getting up to 4 inches.
"Plan on difficult travel conditions, from Monday night through Tuesday and possibly beyond," the weather service said.
Other areas in southern and central Arkansas not under the watch are also expected to see "upwards of an inch of two" of snow, the agency noted.
9:10 a.m. update
Up to an inch and a half of snow was expected in part of northern Arkansas on Sunday, and forecasters say another storm is expected to bring accumulating wintry precipitation to a larger part of the state on Monday.
On Sunday morning, a winter weather advisory was in effect for more than a dozen counties in northern, north-central and Northwest Arkansas. Part of Interstate 40, meanwhile, was closed because of multiple wrecks in "slick and hazardous" conditions, the Arkansas Department of Transportation reported.
"A weak upper level disturbance is moving across northern Arkansas at this time," the National Weather Service office in North Little Rock said in a statement. "This disturbance is producing some light snow and with temperatures being well below freezing, the snow is accumulating."
The Arkansas Department of Transportation reported shortly before 8:30 a.m. that snow was covering a number of roads in the advisory area, including the Harrison area south to Clinton and northwest to Eureka Springs. Click here for the agency's interactive map.
Shortly after 8 a.m., westbound I-40 was shut between exits 64 and 67 in Johnson County "due to multiple accidents from the Interstate being slick and hazardous," the highway agency said. It wasn't clear if anyone was injured in any of the wrecks.

Temperatures were expected to warm slightly on Monday before an arctic front brings colder air and another chance for snow across a wider swath of the state, the weather service said.
"The snow should begin over the north and northwest Monday afternoon and spread slowly south with time," forecasters wrote in the statement. "The front does tap into some additional moisture once it reaches central and southern sections and heavier amounts of snow will be possible."
The weather service cautioned that the event will "not be a major winter storm," but said travel impacts are likely Monday night and Tuesday. Northern Arkansas is expected to get less than an inch of snow while central and southern Arkansas may see an inch to an inch and a half. Two inches of snow is possible in certain parts of south and southwest Arkansas, the weather service noted.
