The Arctic high that has been sitting over the northern plains continues to move eastward. This is enabling ‘warmer’ temperatures for Wednesday to where highs are expected to be in the single digits above zero degrees. This will allow for the wind chill advisory to expire at noon central time today for the entire state. As a high moves east, a warm front along the Earth’s surface will push through driving in some of the warmer air for today. Associated with the front is a chance of light snow for the evening hours and into Thursday morning — accumulations are to stay less than two inches. Once the snow passes, the big story will once again be the brutally cold temperatures. Highs on Thursday are expected to be below zero degrees once again. In fact, the cold temperature trend will last through the weekend as another Arctic high continues to build within the area. Overall, the rest of this week will stay on the quiet side with cold temperatures and a few chances of light snow — but the extended forecast is trending to much warmer temperatures by the start of 2018. An average high temperature for mid to late December is in the mid 20s and lows in the lower single digits.
Wednesday, slightly ‘warmer’ highs, in the single digits above zero degrees and winds southeast/west at 5-10 mph with a mostly cloudy sky.
Wednesday night, a chance of light snow is possible, less than 2 inches are expected. Winds are to be northwest at 5-15 mph from the northwest and wind chills around -20 degrees. Lows in the single digits below zero.
Thursday, highs around zero degrees and a chance of snow in the early morning hours. And winds west at 5-10 mph with a few clouds.
Thursday night, skies, mostly cloudy and lows around ten below zero with a northwest wind and light.
Friday, lows below zero and a partly cloudy sky. Wind chills are expected to be around -20 degrees as there will be a northwest wind at 5-10 mph.
