December has been off to a very mild start across Arkansas with the first week of the month averaging over 15 degrees above normal. This pattern is about to change from T-shirt weather to heavy coat weather as a strong cold front sweeps across the State Sunday ushering in the coldest air of the season so far, and our first taste of Winter like cold. The front will approach by late Sunday evening with showers and some isolated thunderstorms.
After a warm weekend with highs in the 60s and 70s, temperatures will plunge into the 30s by Monday morning. Highs Monday and Tuesday will only reach the low to mid 40s.
Although most of the moisture associated with the cold front will move out of the State as the cold air moves in, an upper level disturbance is forecast to move through early Monday. One of the computer models indicate the disturbance will be strong enough to put out some snowfall for parts of the State.
The above graphic shows total snowfall through 9 AM Monday morning with minor accumulations across parts of Southern, Eastern and Central Arkansas. This model is somewhat of an outlier, as other models are not showing any snowfall in Arkansas at all.
