Large amounts of snow are currently falling across Central Arkansas in the form of thundersnow.
KARK forecasting models show the possibility of 6 to 12 inches of snow falling across portions of the state.
The Winter Storm Warning for Little Rock is set to expire this evening at midnight.
Tuesday, 7:30 a.m. Update:
The National Weather Service has now expanded its Winter Storm Warning area to include Little Rock and a number of cities and counties south of the previous warning area.
The Winter Storm Warning is outlined in pink. The Winter Storm Watch is blue and the Blizzard Warning is red.
According to the NWS, heavy snow has shifted farther south than in previous forecasts. The projected track of the storm system producing the snow is farther south than anticipated. Colder air will be allowed to penetrate more into Arkansas, so now the southern counties have better chances for snow accumulations. Meanwhile, drier air will be allowed to flow into the northern counties, which will keep accumulations down in the northwest. The cross section of the atmosphere from Wichita, KS to Little Rock, AR shows this. There is deep moisture the farther south you go, and more shallow moisture in the north. Areas like Fayetteville should get less snow than neighboring areas to the southeast given less available moisture.
In preparation for Tuesday evening's predicted Christmas Day snowfall, the National Weather Service has issued a Winter Storm Warning for northern Arkansas and a Winter Storm Watch for a line of counties immediately south of the warning area.
As you can see on the map, the pink area which includes Russellville, Searcy, and Batesville is included in the Winter Storm Warning. Hot Springs, Arkadelphia, and Little Rock are in the blue area which indicates a Winter Storm Watch.
The Winter Storm Warning means 3-6 inches of snow are possible and travel is expected to be treacherous.
The Winter Storm Watch means 2-4 inches of snow are possible and travel could become treacherous.
