Winter Weather Advisories have now been issued for about the northern third of Arkansas. You can see the latest map of advisories at http://www.srh.noaa.gov/lzk. In general, the area covered by the advisories should see 1 to 3 inches of snow. The largest amounts should be at the higher elevations and places close to the Missouri border. There is also a concern that the area from near Batesville northeastward could see some of the heavier amounts.
It’s still possible that a few more counties could be added to the advisories later this evening. Snowfall amounts could be adjusted in later forecasts, as well, but I don’t believe there would be any drastic changes to the amounts.
South of the area covered by the advisories, from west central through central to east central Arkansas, totals are expected to be an inch or less.
Farther south, a mixture of rain, and some sleet and snow will probably occur.
All significant precipitation should exit Arkansas by dawn on Monday.
Timing: Snow began about midday in the northwest corner of Arkansas. As the afternoon goes along, snow should spread into north central Arkansas and some of the higher elevations of the Ouachita mountains. This evening, snow should spread to northeast, west central, and central sections. After midnight, snow should make it to east central Arkansas. In all areas, there may be a period of sleet or a mixture of sleet and snow before all precipitation turns to snow. In southern Arkansas, rain will gradually become mixed with sleet and snow in some areas, beginning in southwest Arkansas this evening and spreading eastward after that.
Winds will be picking up from this evening on into the overnight hours. This may help to dry the pavement somewhat where only small amounts of precipitation have fallen on the road. However, temperatures are forecast to fall into the teens tonight in northwest Arkansas and into the 20s over the rest of the state, except the southeast corner. Thus, where moisture does remain on the road, icy patches will develop.
Keep up with changing wintery weather conditions here.
