<Here comes the Arctic air screaming down from Canada to the S like a jailbreak. Temps are in the teens and single digits in the Upper MD and N Plains now, and the leading edge has the snow falling in MO, WI, IL, IA and shortly into MI and IN. Winter weather advisories are up for the area and some warnings in N IN/W MI for around 5-10” of snow. The main surface low is struggling to move northward into NE, but that is producing a separate shot of rain and snow in the NE. Check out the radar!
I’ll show you the big picture on the show, but you don’t need me to tell you air travel will be slow from the NE to the MW.
High pressure under a big ridge dominates the W half the the US, so there will be no problems traveling W of the Continental Divide today. Later!
