We have several weather events on the way in rapid succession across the area. Let’s get right to them.
Event number one is happening now. When storms come from this area they don’t have much moisture and amounts are usually light. Additionally, the system is moving rapidly eastward so it will only last a few hours and will be long gone by sunrise.
I am only expecting 1-2 inches of light fluffy snow at best. (isolated 3″ possible) The biggest impact will be to some of your neighborhood roads which will be a bit slippery. I wouldn’t be surprised if some of you don’t even see the inch so set expectations low for this one.
Saturday, a second storm develops to our southwest and follows the jet stream which takes the storm under our south coast. This track will bring the storm out over the ocean and allow some ocean moisture to enhance the snowfall. Saturday’s storm, while not large, will likely produce the first plowable snowfall for many of you. Boston proper has still not had the plows out yet. I expect this to change Saturday morning. If you have plans Friday night you will not any weather issues. If you have an event Saturday morning, I would venture to guess that some places will postpone them. This won’t be a big storm, but because we have not had much snow, there may be the usual panic. There is no need to shop for even one extra item for any of the weather events over the next few days.
Accumulations for Saturday look to be in the range of 2-6 inches with the highest amounts around the Mass Pike and south. Even the Cape and Islands will see accumulating snow though it will be wetter snow. Most of the snow will fall from about 3 a.m. Saturday until 3 p.m. across the area. Remember, those times are for the entire area. So for those of you further south the snow will start around 3 a.m., but end as early as noon. Folks further to the east will see snow starting a bit later and ending later. If you have plans for Saturday night, I would not cancel them. Roads will be cleared and treated by that time.
Event number three comes at us from the south later Sunday. This will be caused by warmer air moving in at high levels. Think of it this way, if you had a big ladder and went up to about 10,000 ft. Sunday, it may very well be warmer up there than it will be down here. That warm air could cause some sleet or freezing rain in spots away from the coast. Since it takes a very small amount of that type of precipitation to create driving issues, we will have to monitor that closely. The most likely spots to experience icing would be west and north of I-495. This will not be anything more than a few hours of icing if it happens.
Our fourth and final weather event in this series comes Monday. By Monday the warm air will have beat out the cold air and I am looking for several hours of mild rain. That mild air will stick with us for much of next week, so if you want to take advantage of the snow. The best time will be Saturday at the end of the day and much of Sunday.
