DAYS 1-5 (JANUARY 3-7)<\/p>\n\n\n\n
A stretch of unsettled weather will last most of this forecast period. Previous discussion basically holds. Low pressure will pass through our region in strung-out form, and the main forecast question yesterday was how far north a frontal boundary would get as a warm front tonight and Wednesday before being pushed southward by eastern Canadian high pressure as the elongation of low pressure was going by our region. Today’s answer is similar, but adjusted slightly to the colder side – less frontal progress – which is not a surprise as we have seen this set-up many times and it’s something I’ve been concerned about for a few days now. Being on the colder side of the boundary does set up some potential for slick travel later on. With this first batch of rainfall coming in today, developing and moving in around midday, while it is chilly, the temperature will sit above freezing in all areas, so icing is not a concern, nor is it during the main batch of rainfall as it passes through this afternoon and tonight. A break comes for much of the daylight hours Wednesday, but another batch of steadier rain comes in later, into the night and into early Thursday. Lower level cold will be more established at that time and the temperature may be at or even slightly below freezing over interior portions of southern NH and northern MA, creating icy conditions on untreated surfaces. Still additional precipitation will be around, albeit more spotty in nature, as we move into later Thursday and Friday, but this time enough cold air will have worked in aloft so that some sleet and snow will be involved, although not heavy. But this can add to some slippery conditions on untreated surfaces, and this time a little further south and east, while mix\/rain may still be involved closer to the South Coast region with less of a chance of slick conditions there. Again not looking for a major winter weather event, but since we’ve lacked having to deal with slippery conditions much of the season so far, it’s important to note that it can be around and be on the look-out for it. By Saturday, the atmosphere will be drying out, but with some instability left as upper level low pressure still has to pass through, I am keeping the chance of a few snow showers in the forecast.<\/p>\n\n\n\n
TODAY: Cloudy. Periods of rain midday on. Areas of fog developing, becoming particularly dense along the South Coast. Highs 36-43 except 43-50 South Coast. Wind SE under 10 MPH except around 10 MPH coast.<\/p>\n\n\n\n
TUESDAY NIGHT: Overcast and foggy with periods of rain. Temperatures steady or slowly rising. Wind SE to SW 5-15 MPH, except may remain SE in areas to the north of the Route 2 corridor.<\/p>\n\n\n\n
WEDNESDAY: Overcast. Areas of fog, especially north of I-90. Periodic rain showers, also areas of drizzle favoring locations north of I-90. Highs 40-47 southern NH and northern MA and 48-55 elsewhere morning to midday, then cooling temperatures from north to south during the afternoon. Wind SW 5-15 MPH with higher gusts except E around 10 MPH in southern NH and far northern MA, becoming NE 5-15 MPH in all areas from north to south from midday through afternoon.<\/p>\n\n\n\n
WEDNESDAY NIGHT: Overcast. Areas of fog evening. Periods of rain which may convert to freezing rain over inland areas of southern NH and northern MA overnight. Lows 31-38. Wind NE to N up to 10 MPH.<\/p>\n\n\n\n
THURSDAY: Cloudy. Periods of rain except potential freezing rain early in the day interior southern NH and northern MA, may mix with snow starting north and trending south during midday and afternoon. Highs 33-40, mildest South Coast. Wind NE to N 5-15 MPH.<\/p>\n\n\n\n
THURSDAY NIGHT: Cloudy. Periods of light snow and sleet but can still be mixed with rain South Coast. Lows 27-34. Wind N 5-15 MPH.<\/p>\n\n\n\n
FRIDAY: Mostly cloudy. Chance of light snow except some mix\/rain possible South Coast. Highs 34-41. Wind N to NW 5-15 MPH.<\/p>\n\n\n\n
FRIDAY NIGHT: Mostly cloudy. A snow flurry possible. Lows 25-32. Wind NW 5-15 MPH.<\/p>\n\n\n\n
SATURDAY: Variably cloudy. A snow shower possible. Highs 36-43. Wind NW 5-15 MPH.<\/p>\n\n\n\n
DAYS 6-10 (JANUARY 8-12)<\/p>\n\n\n\n
Moderate confidence forecast for mainly dry weather with near to slightly above normal temperatures, but watching for a minor system around mid period that may deliver brief precipitation, and the approach of another system as early as the very end of the period with another precipitation threat at that time.<\/p>\n\n\n\n
DAYS 11-15 (JANUARY 13-17)<\/p>\n\n\n\n
Lower confidence forecast but still keeping an eye on the first couple days of the period for the opportunity to be impacted by low pressure and rain\/mix\/snow – TBD. Drier weather should follow that. Temperatures near to slightly above normal.<\/p>\n","protected":false},"excerpt":{"rendered":"
