Current GFS forecast for X-mas eve

Stratocumulus clouds hung in today, and temperatures stayed slightly below predicted highs. Clouds are expected to clear for Sunday and temperatures should reach the average high of 41 for tomorrow, the first day of winter.

The well-advertised intense low pressure system is on track for Wednesday, Christmas Eve. The upper air low, originally predicted to linger, now appears to be more progressive and moves into Canada quicker. The long range suggests much colder weather moving in next weekend.
