It is tough to focus on the forecast on this horrifying day! It is truly unimaginable that a person could open gunfire on precious, innocent children. It just takes your breath away. My heart, thoughts and prayers go out to the families of Newtown, CT. God Bless them.
A weak cold front will be dropping southward across the region tonight resulting in colder weather tomorrow. After today’s upper 40s, take away ten and you have the upper 30s tomorrow and again Sunday. A ridge of high pressure will nudge down into the region from Quebec providing sunshine tomorrow but an approaching system from the Midwest will distribute its cloudiness tomorrow night with some precipitation to follow on Sunday afternoon. It will commence as snow showers then change over to sprinkles and rain showers near and south of the MA Pike so the Pats/49ers Game will likely be misty and wet with a raw breeze and a temperature near 36 degrees. Meantime, the highest risk of accumulating snow will exist near and north of Route 2 northward into northern New England. The potential exists for a coating up to two inches closer to the NH border with a few to perhaps several inches north of that Sunday night and Monday morning. The rest of the area is destined to receive occasional light rain or drizzle. The first batch of precipitation will be generated by a frontal boundary. The second surge of precipitation should be steadier and heavier later Monday afternoon into early Tuesday morning. The air will be warming especially aloft to create rain farther north into southern NH while the snow becomes mixed with sleet and freezing rain north of that. A wave of low pressure will track northeastward up over Cape Cod Tuesday morning so the rain and drizzle will taper off during the morning. As that wave advances into eastern ME, it may intensify as a vigorous upper level storm transits from NY and PA into New England. This action may pull down some periods of snow or snow showers into southern New England Tuesday night into Wednesday.
Looking ahead, that storm will exit and the next ridge of high pressure will build eastward to provide sunshine and lower to middle 40s on Thursday. Following that brief break, the next powerful system will charge into the Northeast causing gusty winds and bursts of moderate to heavy rain next Friday. Presently, it is too premature to be highly confident of where the rain/snow line will occur but I am leaning to some heavier snow in the northern mountains. After the storm exits, partly cloudy and colder weather will follow for the weekend before Christmas. Most indicators at this time do not favor a White Christmas here. However, there is plentiful arctic air in Canada and an evolving active jet stream. So it wouldn’t take much to slightly alter the steering currents to support snowfall here from at least one of the impending storms. We shall see. Are you hoping for a White Christmas?
Joe Joyce delivers his latest WBZ AccuWeather Forecast in the morning and I shall follow later in the day.
Have a good weekend.
