AM All Zones Update: Few Snow Showers Possible Sunday, Rain Likely Tuesday & Wednesday

/by

Large high pressure over the Lower Ohio Valley and Mid-Atlantic regions, will provide mostly sunny skies today. But a deep northwest flow, will keep a cold airmass with temperatures several degrees below seasonal averages, over the region. High temperatures will be in the lower to middle 30s, again by this afternoon.

Then high pressure starts moving offshore tonight. It remain cold and dry. But the flow with turn more southerly. Some clouds will increase during the evening and overnight hours, well ahead of a weak storm system to the west. More cloud cover and a light southerly flow, will likely keep low temperatures a little warmer tonight. Lows will likely be somewhere in the 20s, for most of the region.

Cold air, snow showers to close out the week

/0 Comments/by

This holiday week has generally been characterized by the return of colder air (after quite a warm start from the tail end of the weekend) and chances for light snow. Much of the same will continue on Thursday, as temperatures in the 20’s to near 30 will be common during the afternoon and a weak disturbance passing through aloft will spark the development of snow showers throughout the area. The weak low pressure system forming offshore and the relative lack of moisture means that precipitation will be spotty at best — but nevertheless, some flakes should fly especially across New Jersey and much of the interior. Accumulations are expected to be extremely light.

Another cold night is expected from late Thursday into Friday, as the aforementioned developing low pressure system pulls down one more reinforcing shot of cold air. Low temperatures in the teens and 20’s should be rather common by early Friday morning. Despite the light snow over the past several days, the weather pattern has been generally quiet. But beginning with a storm system late this weekend, the activity looks to kick up once again as we make our way into January.

Northeast US surface analysis on December 26, 2013 showing a weak coastal low forming offshore.
