Record Cold West, Record Warmth East

Low temperature records were set from Oregon and Utah south through southern California the past two days, while in the eastern U.S. record high temperatures were recorded in the southeast and mid-Atlantic.

Surface temperatures at 3:00 p.m EST January 14 (left), and at 7:00 a.m. PST January 15 (right).

The reason for this was a very amplified upper air pattern, with a ridge in the Pacific and a ridge in the Atlantic, with a broad and deep trough in between.

In the west, strong northerly winds aloft brought air south from the Yukon and Northwest Territories. In the east, air was being drawn from the Pacific through Mexico and the Gulf of Mexico.

There were numerous record lows in the west the last two mornings.
