CHRISTMAS DAY 2022

Warm and wet – well 10C. North America suffering from record cold temperatures. I think I have got the analysis correct. Cold air has been brought south throughout the centre of the continent by the jet stream shifting south to the Gulf of Mexico. This is bringing very cold conditions to the Prairie states, although Manitoba has yet to declare a weather warning as -40F temps are not that unusual!! There is also low pressure system over the NE of the continent which is also bringing cold air from the Arctic, but also moisture and high winds – snow, blizzards and freezing rain and icy conditions. Low pressure in the Pacific Region is also bringing snow to Vancouver and British Columbia. Just as temps fell quickly they may do the opposite over the next few days. The following article from Bloomberg, whilst being full of hyperbole, suggests that climate change is responsible for the erratic changes in the jet stream.
