A major change in the upper level flow regime over North America has allowed Arctic air to spill south into much of the central and northern Plains as of Thursday morning.
The source of the cold air is massive, extending well into Canada where as of yesterday, Wednesday January 10, there were temperatures from -40 to -50! It won’t get that cold in Kansas but it will get plenty cold. The map below indicates the high temperatures expected Saturday.
Besides the cold temperatures, frozen and freezing precipitation is expected across the area. Freezing drizzle is expected to begin later tonight and continuing into Friday, starting first near Interstate 70 and then developing or moving southeast across the area. However, at this time amounts don’t appear to be too great. However, as a strong upper level storm moves into the central plains over the weekend, more substantial precipitation is expected to develop. It now appears that much of the area will miss significant amounts of freezing rain but the threat of snow has increased. The map below is the latest forecast of snow and ice amounts based on the forecast from Thursday afternoon...
