The weather pattern will get pretty interesting next week to coincide with the beginning of the month of December and it will include some significant temperature and height anomalies across North America for this time of year. High pressure ridging in the upper part of the atmosphere will intensify dramatically next week across Canada at the same time colder-than-normal air sets up across the south-central US and there will be plenty of strong energy aloft. The transition to this possible colder and stormy weather pattern in the US (and warm weather pattern across Canada) could be preceded by a significant rain event in the eastern states as we end the month of November.

A cold front will pass through the region early today and high pressure will build across southeastern Canada from later today into Tuesday.

This high pressure system will lose control around here at mid-week and showers are likely to arrive by Wednesday night associated with low pressure to our northwest and they could last into Thanksgiving morning.

Many spots in the Mid-Atlantic/Northeast US have already experienced at or below-freezing temperatures this season, but, if not, additional opportunities will come on both late Tuesday night and late Wednesday night of next week.
