For The Rest Of This Afternoon: An intense storm system located well south of Nantucket is producing snow as far north and west as the Cape and far eastern Mass at the time of this writing. It is expected that this shield of snow will gradually rotate westward and may push into eastern parts of Worcester County by sunset. Further west, cloudy skies are expected the rest of this afternoon across the rest of Central Mass with partly sunny skies expected across Western Mass. Temperatures the rest of this afternoon will be around 35 Degrees. Winds will be North at 10 to 20 mph with gusts to 30 mph. Tonight & Monday: That strong low pressure system is expected to push that shield of snow further west into Central Mass during the overnight hours of tonight. In fact, some of the higher resolution weather forecast guidance indicates that some snow may occur as far west as the I-91 corridor late tonight into Monday morning. That said, there’s considerable uncertainty as to whether the snow will back as far west as I-91 or whether any snow will be limited to areas from the Worcester Metro and points east. Given the look of the models, which seems to be trending towards a little more of a widespread snowfall tonight into Monday morning across Central Mass and parts of Western Mass, I think that we will probably see light snow spread westward across Central Mass this evening. Light snow is anticipated to reach as far west as the lower Pioneer Valley of Western Mass after midnight tonight, while it continues to snow lightly across all of Central Mass after midnight tonight. During Monday morning, periods of light snow is expected to continue across Central Mass, while the snow ends across Western Mass. The light snow will end everywhere by midday Monday. As for snow amounts tonight through Monday morning – For Western Mass, little or no snow accumulation is expected across a majority of Western Mass. The exception may be across the lower Pioneer Valley where a dusting of snow is possible. As for Central Mass, snow amounts of one inch or less looks possible across areas of western and far northern Worcester County into the I-84 corridor. Further east, a snow accumulation of 1 to 2 inches is expected near and east of I-190 and near and east of I-395, including the Worcester Metro. 2 to 3 inches of snow is a possibility tonight into Monday morning across areas that are east of Route 146. Low temperatures tonight will be between 20 and 25 Degrees. High temperatures Monday will be near 35 Degrees. Winds tonight will be North at 10 to 20 mph with gusts to 30 mph. Winds on Monday will be North at 8 to 16 mph. Tuesday & Wednesday: A weak frontal system is expected to pass through the region late Tuesday into early Wednesday. Tuesday is expected to be cloudy and there may be some late day scattered rain showers. High temperatures will be near 45 Degrees. Tuesday night looks cloudy with some scattered rain showers around. Low temperatures will be between 35 and 40 Degrees. Wednesday will start out cloudy, but will become partly sunny by afternoon. High temperatures will be near 45 Degrees. Thursday & Friday: An area of low pressure is expected to track near the south coast of New England during Thursday night. This storm system is expected to bring a round of precipitation to the entire area during Thursday afternoon, Thursday night and part of Friday. The question, however, is what form will the precipitation be in and where could the snow, ice, rain lines set up across the region. It appears that this will may end up being a messy mixed precipitation storm where snow, sleet, freezing rain and rain would all occur. The higher chances for accumulating snow with ice may end up being across areas north of the Mass Pike. Near and south of the Mass Pike, more rain than ice or snow looks possible. That said, there is still plenty of time to watch this storm and more detailed information will be forthcoming as we get closer to the event.
