Big Changes for Midwest & East
It has been a very warm October for a good part of the nation from the Midwest to the East Coast. The graphic below shows temperatures relative to normal since October 1. The green and blue areas show below normal temperatures in the Pacific Northwest and Rockies while all the orange and red show above normal temperatures since the beginning of the month.
The trend for the first three weeks of the month, however, is about to change. A large swath of cold air will descend south out of Canada and into the central and eastern states later this week bringing much colder temperatures. Another shot of much colder air will arrive just after Halloween and into the first week of November.
Beef producers in the Midwest to the East Coast should be prepared for sharply colder temperatures by this weekend and again next week.
A major change in the jet stream pattern will develop that will allow the door to be open from Canada resulting in much colder pattern for the last days of October and into early November.
