Discussion
A major pattern change to cold begins today following the passage of a strong cold frontal system and temperatures this afternoon will be noticeably colder than yesterday’s mild conditions. This change to cold will be rather sustained with a good chance for below-normal temperatures on average from this point through most, if not all, of the month of December. This initial shot of cold air will feature an intensifying trough of low pressure in the eastern US with plenty of waves of energy rotating through and each system will attempt to generate low pressure near the east coast. As a result, the threat for some snow or snow shower activity will persist from later this week into the upcoming weekend. Signs point to an even colder air mass to arrive next week in the eastern US which will be way below-normal for this time of year and this blast may be accompanied by some snow.
