DAYS 1-5 (JANUARY 9-13)<\/p>\n\n\n\n
It’s an active pattern now after winter’s so-called “slow start”, which wasn’t really a slow start, it was just kind of typical for a La Nina pattern, and so is what we’re about to experience, just a little different from what we had. After our recent snow, we had a beautiful winter’s day on Saturday with lots of sun, a diminishing wind, and cold that was tolerable without wind. Today, as the atmosphere tries to warm up, and a low pressure system passes to our north sending precipitation our way, it’s warming up enough aloft so that precipitation is going to be falling as raindrops or melting from snowflakes into raindrops as it exits its birthing region in the middle troposphere. From there it will fall into colder air closer to the ground. It’s going to reach the surface in the form of rain for most, although the cold air may be thick enough to freeze it into ice pellets (sleet) over some interior areas for a while this morning. In a large portion of the region away from the immediate coast, the temperatures sit below freezing (from the upper 20s to very low 30s) as the initial batches of rain will be moving in from west to east. This spells freezing rain, and will create slippery conditions on untreated surfaces. Eventually, the surface temperatures will warm enough to eliminate this issue, but it may take several hours to do so, until a warm front gets by our area and the surfaces temperatures warm sufficiently to the upper 30s to near 40 later today. In the mean time, if you plan to be out driving or walking, keep in mind that untreated surface may be glazed with ice that is difficult to see. And tonight, once we get the cold front through, our rain threat ends, but cold air comes in quickly and again any wet and untreated surfaces will return to their icy state, being a factor later tonight as well as tomorrow until they can be treated or dry off (sublimate) enough. Tomorrow’s weather will be mainly fair, but windy and on the cold side, however this will be nothing compared to the air mass that arrives tomorrow evening with an arctic cold front, possibly announced by some snow showers and snow squalls. I’ll fine-tune that threat on the next update to the best of my ability. Squalls or no squalls though, that air mass means business, bold and cold, and Tuesday’s temperatures will struggle to be above 10 for most of us during the day, with wind chills well below zero. When we moderate back to the 20s Wednesday and the 30s Thursday, it may feel like a veritable heatwave in comparison. We’ll also have to watch a weak disturbance or two coming along from the Great Lakes \/ Midwest by midweek for some minor light snow threats, but these don’t look too impressive to me at the moment.<\/p>\n\n\n\n
TODAY: Cloudy. Episodes of rain possibly mixed with sleet this morning, with freezing rain away from the coast eventually transitioning to non-freezing rain later in the day. Highs 36-43 occurring late in the day, except 43-50 Cape Cod. Wind calm early, then S up to 10 MPH, shifting to SW and increasing to 10-20 MPH by late in the day.<\/p>\n\n\n\n
TONIGHT: Mostly cloudy evening including a chance of rain showers South Coast \/ Cape Cod. Clearing overnight. Black ice formation on untreated surfaces. Lows 22-29. Wind NW 10-20 MPH. Wind chill below 15 at times.<\/p>\n\n\n\n
MONDAY: Mostly sunny to partly cloudy. Isolated late-day snow showers. Highs 25-32. Wind W 10-20 MPH.<\/p>\n\n\n\n
MONDAY NIGHT: Partly cloudy with a chance of snow showers \/ squalls evening. Clear overnight. Lows 3-10. Wind NW 10-20 MPH and gusty. Wind chill -5 to -15.<\/p>\n\n\n\n
TUESDAY: Sunny. Highs 8-15. Wind WNW 10-20 MPH. Wind chill below 0.<\/p>\n\n\n\n
TUESDAY NIGHT: Clear. Lows -2 to +5. Wind NW 5-15 MPH, diminishing. Wind chill -5 to -15 evening.<\/p>\n\n\n\n
WEDNESDAY: Increasing clouds. Chance of light snow late-day. Highs 22-29. Wind variable up to 10 MPH.<\/p>\n\n\n\n
WEDNESDAY NIGHT: Mostly cloudy. Scattered light snow possible. Lows 15-22. Wind variable under 10 MPH.<\/p>\n\n\n\n
THURSDAY: Partly sunny. Highs 30-37. Wind SW up to 10 MPH.<\/p>\n\n\n\n
DAYS 6-10 (JANUARY 14-18)<\/p>\n\n\n\n
We enter a period of vulnerability to be impacted by first a storm over the ocean to our south, and second a low pressure area moving this way from the Midwest. It’s far too early to tell if we’ll be directly impacted by either or both of these threats, but it is something we should pay close attention to. Temperatures during this period will run below to near normal.<\/p>\n\n\n\n
DAYS 11-15 (JANUARY 19-23)<\/p>\n\n\n\n
Basically the situation of the previous period is expected to continue this period as well, with us in a pattern that’s vulnerable to cold and some threat of wintry precipitation. As you have already heard countless times, we can’t just look at run-to-run model guidance to try to pin point which days carry the highest threats and what might happen in each location. You know the drill by now – just something to watch and fine-tune things with time.<\/p>\n","protected":false},"excerpt":{"rendered":"
