this is Montana with biting sub-zero wind chills.

Record cold West delivers a record warm East when you’ve got a highly amplified pattern.

This morning’s record -7 follows a record cold high of 13 in Denver yesterday.

In a day and a half, Denver dropped 72 degrees.

A lot of weather along the eastward progressing boundary just now separating summer from winter.
