From the National Weather Service in Little Rock
Arctic air is arriving from the Plains Friday morning. A gusty northwest wind will produce wind chill index values from zero to ten below zero in the northern two to three rows of counties in Arkansas.
Below to much below normal temperatures will continue through the weekend. Saturday will be the coldest day, with lows in the single digits and teens and highs in the 20s and 30s. Minimum wind chill indices will be in the single digits above and below zero Friday night into Saturday morning.
Late Sunday night and Monday, Arctic air will begin exiting to the east. Clouds and moisture will increase, with rain developing. Precipitation will likely start off as freezing rain, with the potential for at least a tenth of an inch of ice in northern/western sections of the state.
Rain will continue through at least Thursday. The forecast calls for one to more than three inches of rain across the region, with the heaviest amounts over the southern counties.
