“Warmth at the top of the atmosphere has snarled up lower levels into a twisted contortion of swirls and eddies. That, in turn, has blocked off our normal westerly winds and opened the gates for frigid air to spew towards us on north-easterly winds from the Arctic. This cold, dense slab of air is hard to shift.
“The next threat comes early this week, with the approach of another Atlantic weather system. More heavy snow looms, and although the milder air may briefly have the audacity to sneak into some south-western areas, turning the snow back to rain, the cold air will soon sweep back in from the north-east.”
