Winter Weather Briefing and road conditions for Arkansas from the National Weather Service and IDriveArkansas
Snow has let up over most of the northern half of Arkansas. Another round of snow and sleet is expected to develop across the southern half of the state, with additional accumulations of 0.5” to 1” possible through this afternoon.
Travel impacts (including hazardous road conditions and reduced visibilities) will be possible where snowfall or sleet occurs, including major throughways, bridges/overpasses, and rural roads.
Bitterly cold temperatures, much below climatological averages, are expected to continue through at least Tuesday night and into Wednesday morning. Temperatures have fallen to single digits to below-zero in portions of northern Arkansas, and daily high temperatures will likely not rise above freezing again until Wednesday afternoon (at the earliest) for most areas of the state.
Morning minimum wind chill values will remain below zero degrees over a large portion of Arkansas, and persist at hazardous levels through at least Wednesday morning due to abundant Arctic air and breezy conditions.
A brief reprieve from below-normal temperatures will resume on Wednesday and Thursday, and another shot of Arctic air is forecast to move into the region by late this week, bringing more belownormal temps through this coming weekend.
