A weak wave of low pressure southeast of Nantucket is moving away from New England so today's sprinkles and light showers over southeastern Massachusetts have ended but the clouds will linger and blot out the light of the Full Beaver Moon through much of the night over many areas. Meantime, we're watching a cold front chugging across the Great lakes. It is destined to pass through the Boston area late tomorrow afternoon to early evening with nothing more than a band of clouds. Between tonight's clouds and those clouds arriving tomorrow afternoon, there should be a spell of sunshine developing tomorrow morning. The temperatures will max out near the average for November 3 at 56 degrees but, after that, chillier weather will persist through Saturday morning. With the cold frontal passage, the wind will become brisk tomorrow night into Wednesday morning. Until then, the westerly breeze will be rather meager. Then as a large zone of high pressure builds into the Northeast Wednesday, sunshine will be prevalent through midday as the wind slackens. Later that afternoon, the high cloudiness will be appearing as the next weathermaker dives toward the region. It consists of two parcels of energy in the upper air. It appears that there will be a phasing or linkage of these packages which will trigger cyclogenesis over the ocean. The storm's precise place of birth, intensification rate and departure speed will determine if coastal New England will reap any precipitation. Presently, the initialization is projected to occur well out at sea suggesting that most of the backlashing will miss the region. However, as the amplifying trough of low pressure passes overhead, a few spotty rain showers could happen Thursday afternoon and evening with a potential switch to snow showers and flurries over hillier terrain farther north and west of Boston. Any early snowflakes Friday morning will vanish as the storm tracks south of Nova Scotia and a strengthening ridge of high pressure closes in from the west. As a result, the gusty wind will blow much of Friday as sunshine becomes more widespread but temperatures will fail to rise above the lower to middle 40s. Once the ridge of high air pressure sets up south of New England, a return southwesterly flow of milder air commences over the weekend when it will be mostly sunny to partly cloudy. Temperatures will rise to near or a bit over 50 on Saturday, 55-60 on Sunday and 60-65 on Monday.
Have a good Tuesday.
