Forecast discussion: if you went outside anytime in Boston on Monday, you would think every calendar was wrong. After a morning low of 19 degrees, the high in the capital city was only 31 degrees. It felt more like early February then almost the end of March. It will feel like winter for a couple more days, especially as eastern Massachusetts braces for a Nor’Easter for Wednesday.
The computer models have been forecasting this storm for the last several days. The National Weather Service already has a Winter Storm Watch in effect for Bristol and Plymouth Counties from midnight to noon on Wednesday. There is the potential of seeing up to 6 inches in this area. Meanwhile, the Cape and Islands are under a Blizzard Watch, for the same time frame. The only difference is they will see storm force winds and low visibility during heavy snow. There is a chance this area sees a foot of snow by Wednesday afternoon. Also, due to the strong winds, coastal erosion and some minor coastal flooding is possible. That is why a Coastal Flood Watch is in effect, for Nantucket and Barnstable County. The north and east side of any coastal areas and beaches will see the strong winds and storm surge move towards the coast. Storm surges may reach between 2 to 2.5 feet. This is also bad as high tide is expected Wednesday morning at around 9 a.m. Sandwich and Provincetown Harbors could see sea heights of 8-10.5 feet. For Boston, I am expecting about 3-5 inches of snow for the capital city. However, please check back in tomorrow night. If the low comes back west even 30 miles, this will change the snowfall totals dramatically.
By early Wednesday afternoon, the snow will taper off, and winds will diminish into Wednesday evening. High pressure will give us a nice day for Thursday, with some clouds taking over the skies by Thursday night. A cold front will bring a round of showers into the region for Friday, and south winds will help raise our temperatures into the middle 50’s. We will remain cloudy, as a second low pressure system that developed over Arkansas will bring more rainfall for Saturday. Some of the rain may be heavy at times Saturday afternoon. The low will move offshore by the middle of Sunday morning and high pressure ridging will begin to build over us. This will give us partly to mostly sunny skies for the rest of Sunday afternoon and Monday. Temperatures will rebound back into the middle to upper 50’s for highs on Monday afternoon.
