As we await the blast of cold air that will arrive late in the weekend, we will see another 24 hours of temperatures above freezing in most areas.
Tonight, a returning south wind and overcast skies will keep lows from dropping below 32 degrees. Most areas will settle into the mid to upper 30s.
For Saturday, it will remain overcast through much of the day. We may see fog develop across much of the region and linger through the day on Saturday. Areas of drizzle and light rain are possible as we move through the day, but any rainfall accumulations will be light. Highs will be in the 40s.
Our attention turns to a strong arctic front that will being dropping temperatures below freezing late Saturday into Sunday morning. If the areas of light rain and drizzle are ongoing, we will see a brief changeover early Sunday into freezing rain, sleet, and snow. Due to the light nature of the precipitation, very little accumulation is expected so at this time we are not anticipating any widespread impacts, though bridges and overpasses may see some light icing. The best prospects for snowflakes will be across the northern ArkLaTex (I-30 corridor). We could see frozen precipitation as far south as I-20 ending by midday Sunday. We will wake up to temperatures in the 30s Sunday morning, but by the afternoon and evening we will have fallen into the 20s. For any outdoor New Year’s celebrations, midnight temperatures will be in the low/mid 20s with wind chill values in the teens.
(Futurecast snapshot of freezing rain/sleet/snow development Sunday morning):
The very cold air will stay in place for much of the upcoming week. We may see highs fail to warm above freezing for much of the ArkLaTex Monday and Tuesday with overnight lows in the teens, and wind chill temperatures dropping below 10 degrees in the morning. Most areas will return to the 40s by Wednesday. Monday through Friday is looking dry.
