Arctic Air Heading This Way
(24 hour temperature change across the nation. Notice the cold outbreak in the Dakotas)
When you think about it, this winter in Arkansas has been fairly mild. In fact, in this January we've gone through several stretches where temperatures have been above 60 degrees. Well, this whole mild feeling is about to come to abrupt end real soon.
A strong arctic high pressure system is moving in from the northern suburbs of Canada and setting up shop in the middle of the country. Just out ahead of the high pressure system is the cold front that will alter our weather pattern for the next few days.
Initially as the cold front sweeps through late this evening there will be a brief period of snow that will fall in Missouri and the northern tip of Arkansas. Accumulations at this hour look extremely low and on the range of an inch or less.
(FOX 16 Snowfall model shows barely less than inch of snow in Northern Arkansas early Thursday morning.)

Once the front sweeps through late tonight and the arctic air floods the state tomorrow morning, our temperatures are going to nose dive. What makes this cold punch unique from the other ones we've experience this winter season are the winds. Unlike the last cold plunges, we've hardly felt a single gust outside when we've dropped down to freezing, but now with this pressure setup were looking at wind gusts approaching 30-35 mph tomorrow. When you factor the wind and temperatures on Thursday, were looking at it feeling like the 20's outside...all day long.
Needless to say, were about to go through a cold patch real soon. Even though that doesn't sound too pleasing, our weather will improve as we approach the upcoming weekend. Thanks to a southwest wind and a fair amount of sunshine ahead were looking at a nice rebound by time we reach Saturday.
