Wednesday January 30

The infamous Polar Vortex is sending a lobe across Chicago and Detroit today, the lifts into eastern Canada. It is sending bitterly cold air our way, which will arrive with a snow squall along the arctic front mid day. This burst may look like a blizzard for 15 to 30 minutes, and then you wil feel the difference. So as cold as it is this morning, it will be painful this afternoon and more so Thursday morning.



Wind Advisory Today: Wind Gusts to 50 mph

Wind Chill Advisory Into Thursday Morning: Wind Chills to -20ºF. Frostbite can occur in less than 30 minutes. 

A Lot Of Info Here

This post has a lot of information! I wanted to highlight that here before you scroll down. First, we need to look at the current set up. This will include at look at the core of the cold near Chicago where frostbite can occur in minutes. Locally, it is cold and still icy in some of the snow zone areas that were not treated enough.

We will check out the temperatures at the core of the cold air near Chicago. Then we time out the arctic blast with three sliders. They include:

  • The Snow Squall
  • Temperatures
  • Wind Chills

Please consider your pets. It will be dangerous for them to go on walks or stay outside.

A cold as it feels this afternoon, we bottom out Thursday morning. Then we coined back up quickly to near 60ºF next week.


Polar Vortex

Technically this is one piece of the Polar Vortex with a lobe that is crossing Chicago and Detroit. But the core will lift into eastern Canada. So we are getting cold air on the edge, but not the main event.


Core Of Cold Air:

While Baltimore is at 16ºF and we have some single digits nearby, compare to the MidWest

Chicago had a temperature of -20ºF, with a Wind Chill of -45ºF.

Arctic Front Tracking Today

Snow Squall —> slider

The burst of snow may last 15 to 30 minutes and briefly look like a blizzard. It will be enough to coat the ground with a dusting to 1 inch. The snow will be very dry and like powder, blowing around easy, but not melting.
