DAYS 1-5 (DECEMBER 15-19)<\/p>\n\n\n\n
A large high pressure area sat overhead overnight and it got cold! Sunrise temperatures sat in the 10s for most of the region, with some lower 20s in the urban centers (heat island effect) and over the outer part of Cape Cod (surrounded by warmer water). The high pressure area starts to drift off toward the east today and as it does so our sunshine will become more limited as high to mid level clouds increase from the west ahead of an approaching low pressure area. At the same time an evolving weak onshore air flow will cause some lower clouds to come in from the ocean in eastern areas. Tonight, clouds collect and consolidate from both sources, and Monday is expected to be a cloudy day as a weak low pressure system approaches. This system will have cold enough air to work with so that some light snow can occur over inland areas, and eventually some freezing drizzle \/ rain, while closer to the coast I’d expect mainly a rain event. However, this system will also be running into a lot of dry air and falling apart as it moves in, so it’s quite probable that the precipitation is nearly insignificant for much of the region. Monday night, a more southerly air flow takes over with increasing moisture so expect a thicker overcast with spotty drizzle and patchy fog to form, and then as a larger area of low pressure begins to pass north of our region, a frontal boundary will be dragged eastward across the region, bringing with it widespread rain showers for Tuesday morning. This system will be moving right along and we’ll dry out that afternoon into early Wednesday. The next low pressure wave on its heels will spread clouds back in on Wednesday with a batch of rain (that can begin as mixed rain\/snow for some interior areas) later Wednesday and early Thursday (which can end as mix\/snow for some areas) as colder air returns.<\/p>\n\n\n\n
TODAY: Sunshine becomes less abundant as clouds increase. Highs 33-40. Wind variable up to 10 MPH.<\/p>\n\n\n\n
TONIGHT: Becoming cloudy. Lows 25-32. Wind variable to S under 10 MPH.<\/p>\n\n\n\n
MONDAY: Cloudy. A period of light snow to mix inland and mix to rain coast. Some potential for icing from freezing rain\/drizzle away from the coast. Highs 35-42. Wind variable up to 10 MPH.<\/p>\n\n\n\n
MONDAY NIGHT: Cloudy. Fog patches. Chance of drizzle. Temperatures 35-42, slowly rising overnight. Wind SE to S up to 10 MPH.<\/p>\n\n\n\n
TUESDAY: Mostly cloudy with rain showers likely morning to midday. Clouds break for intervals of sun afternoon. Highs 46-53. Wind S 5-15 MPH, shifting to W with higher gusts.<\/p>\n\n\n\n
TUESDAY NIGHT: Clearing. Lows 25-32. Wind W 5-15 MPH.<\/p>\n\n\n\n
WEDNESDAY: Clouding over. Rain arrives by late-day, may be mixed with snow initially interior locations. Highs 40-47. Wind variable up to 10 MPH.<\/p>\n\n\n\n
WEDNESDAY NIGHT: Cloudy. Rain likely. Areas of fog. Lows 36-43. Wind NE 5-15 MPH.<\/p>\n\n\n\n
THURSDAY: Cloudy start with rain ending, possibly mixed with snow. Clouds decrease thereafter. Highs 38-45. Wind NE to N 10-20 MPH.<\/p>\n\n\n\n
DAYS 6-10 (DECEMBER 20-24)<\/p>\n\n\n\n
Opportunities for snow or snow showers about 3 times (every other day). Temperatures below normal. We’ll be in a trough position here, and medium range guidance has trouble handling “pieces of energy” and therefore presents inconsistent representations of what can happen on run-to-run simulations. That’s why these are talked about as non-specific opportunities until each “chance” gets closer.<\/p>\n\n\n\n
