A gentle light fluffy snow continues to fall late this afternoon mostly along and south of the Massachusetts Turnpike. The area will slowly move south and east while shrinking overnight. There can still be some snow through the evening commute over south shore communities and over Cape Cod. Generally 1 to 3 inches of snow will have fallen, some of it having melted as it hit the roads. To the north there was less than this with a dusting to 1 inch more common. The radar loop is from late this afternoon and shows the movement of the snow towards the east and northeast.
I'll be updating the forecast as it changes on Twitter at @growingwisdom Please follow me there. Feel free to comment or ask questions too.
I have updated some parts of the blog from earlier today. More on the weekend storm tomorrow.
Another small snow event
A boundary between cold and mild air will remain in place today just off the coast. This boundary is the focal point for our current bought of wintry weather. The snow will quickly be exiting late this afternoon and evening. There is a winter weather advisory south of Boston, but even in the city travel will be impacted a bit late this morning and into the afternoon.
The snow which moved into the area just after the morning commute will exit during the evening commute. Earlier roads were warm enough so much of the snow wasn't sticking, however, now the sun is down any remaining snow will stick better on untreated surfaces. The images below was the forecast radar for 12PM and 4PM.
Across Martha's Vineyard and Nantucket temperatures have fallen close to or below freezing. There can be some rain mixing with the snow or even a period of all rain for a few hours this afternoon. However, as colder air works into the system, all the precipitation will eventually change to snow. Inland areas, over southern Rhode Island and southeastern Massachusetts, will likely see the highest totals.
I am forecasting 1 to 2 inches of snow around Boston with higher amounts, in the 2 to 4 inch range, further south. A few isolated areas could see higher amounts of snow if locally heavier bands develop in the early afternoon.
The evening commute could be impacted a bit as snow remains on the roads, but much of the snow will have ended by 5PM especially west and north of Boston. Those of you heading south could still be dealing with falling snow for a couple of hours after dark.
Arctic air, which is very cold, will spill into the area behind this system. The next three days are going to be January-like with highs in the 20s. On Thursday, there will be areas north and west of Boston where temperatures will stay in the teens much of the day.
Next weekend shows a moderation in temperature, but still readings will be quite below normal. November averaged 2 degrees below normal and thus far the first week plus of December is also averaging quite a bit below average.
Along with a warming trend, another storm, with more significant moisture, is forecast to impact the area later Saturday and Sunday. Right now it appears snow will begin sometime Saturday evening and then we have to watch and see how much warm air makes it into this system. If this ends up being all snow and ice, it could be a more impactful storm than anything we have seen so far. You can see a graph that depicts the weather the next week above. This is based on only one model, by does give a general good idea of upcoming trends.
I still feel that towards the end of the month the pattern will shift again and milder air will ensue. This doesn't mean winter will be over of course, but since we started with the cold so early, it's likely that a break will happen later this month and into January.
Outdoor project this weekend
In this video I show you a project you can do this weekend and bring the kids along too.
