(As always, click on images to enlarge - video forecast is below) After a colder than normal stretch of 10-11 days, depending upon location in New England, near or below normal temperatures are expected in the coming 7 days, and the weather pattern appears to continue below normal temperatures in the 8-14 day forecast period. A jet stream trough will persist in the Eastern United States, with frequent shortwaves (disturbances) reinforcing the trough through the forecast period and continuing to drive shots of Canadian cold into the Northeast corridor. Ahead of a late week disturbance, warm advection (transport of warm air) in the southerly wind will boost temperatures at or below normal for a day, but will bring yet another shot of cool air in its wake.
As for precipitation, one rain making system will depart the Northeast at the start of the period, and the next will run the country from west to east later in the week, tapping the Gulf of Mexico for deep, tropical moisture and producing a swath of heavy precipitation across the Southeast quarter of the nation and into the Mid-Atlantic. What's uncertain at this timeframe is whether a full phase will allow for this surge of deep moisture to produce heavy precipitation in New England, or if the northern disturbance will remain separate just long enough to delay full phasing until the system moves off the coastline.
