It's been warm in the Southeast. On the West coast however, especially in the Northwest, it has been colder than normal. A low pressure zone sucked in cold air from up north in the interior of Canada. There were 3 days in a row where the daytime temperature never rose above freezing. For comparative reference, usually if there is cold spell the temperatures will at least mostly remain slightly above freezing. We got 6 inches of snow, which is a little unusual this early in the year. Usually that much snow does not fall until late January or very early February. Many years there is no snow that actually stays on the ground.
But I do remember one year where the Southeast got that terrible polar vortex, and many people's citrus were killed, while meanwhile in the Northwest on New Years Day it was unseasonably warm and camellia bushes were in partial bloom, and there was even a rose bush that seemed to be trying to send out a new bloom. That year the trunks of the Basjoo ornamental banana plants in people's yards did not even die to the ground.
