DAYS 1-5 (JANUARY 2-6)<\/p>\n\n\n\n
The pick of the first full week of 2023 comes early, and it’s an easy pick: today. But wait, what about those 60s on Wednesday? Shouldn’t we plan a beach day in January? Not so fast. Let’s go through this step by step to see how things really evolve, and why today will be a nicer day than Wednesday. Well, on the surface (yes, it’s a pun), it’s rather simple. High pressure controls our weather today, and even though its center is off to the south it exerts plenty of influence so we have dry air with temperatures a little above the seasonal averages, and while we will see some clouds at times related to disturbances passing to our north, it will be a nice day overall – for many people a holiday (the Monday observance of New Year’s Day). And then things change. You may recall last week that I indicated during this week we would be in a battle zone between warm air to the south and cold air over eastern Canada. The battle gets underway Tuesday as a warm front approaches, bringing in an overcast sky and a period of rain. While this is happening, high pressure will be building in eastern Canada, and a decent supply of low level cold air will be moving into northern New England. I’m not overly impressed with the set-up to push the warm air behind the front too strongly to the north, and this is why I am having my doubts as to how far that frontal boundary will get. For now, I am going to forecast the boundary making it into but not completely through the Woods Hill forecast area – probably into the I-90 and southern I-95 belt,. but maybe not all the way to the northern I-95 belt and the Route 2 corridor northward. If it does make it that far, it’s likely to be for a brief time only, as the low level cold will ooze southward by later Wednesday, assuming it hasn’t been so stubborn that it stayed in places in most areas. This is more easily accomplished as we will have a more strung-out west-to-east low pressure configuration to the south of the Canadian high pressure area. When we see this set-up, the models often forecast the warm air to make it too far north, and while it does move northward above us, it doesn’t really do so very well at the surface. And with plenty of moisture around, this means initially that we can have additional rainfall in the region, but with time, it may turn cold enough at the surface so that freezing rain and\/or sleet become part of the equation, especially over interior locations to the north and northwest of Boston, sometime during Thursday. The scope of the issue this could cause would be determined by how much precipitation is around. We may end up with just spotty light activity, which would limit the trouble. As we get to Thursday night and Friday, cold enough air should move in at mid and upper levels so that whatever falls ends up in the form of light snow or snow showers. It’s uncertain how long that will hang around on Friday. Some guidance dries us out while other guidance keeps the cloud cover and precipitation chances going. Leaning toward the latter for now, but with plenty of time to adjust if needed.<\/p>\n\n\n\n
TODAY: Sun\/cloud mix. Highs 45-52. Wind W up to 10 MPH.<\/p>\n\n\n\n
TONIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 28-35. Wind variable under 10 MPH.<\/p>\n\n\n\n
TUESDAY: 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 45-52 southern NH and far northern MA and 53-60 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. 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
DAYS 6-10 (JANUARY 7-11)<\/p>\n\n\n\n
Trend is drier for the January 7-8 weekend but still may be some instability around the region with a passing snow shower or two possible especially the first half of the weekend, along with more seasonably chilly air. Brief precipitation threat may exist sometime in the January 10-11 time frame from the remains of a system trying to move through from west to east.<\/p>\n\n\n\n
DAYS 11-15 (JANUARY 12-16)<\/p>\n\n\n\n
Continuing to watch time windows of January 12-14 and again at the end of the period for potential precipitation threats from an active Pacific to trans-US storm track. It’s always difficult to time these things so far in advance, so for now read this as a fairly active \/ unsettled pattern for mid month with temperatures near to above normal as I think coldest air will be prevented from or limited in moving into this region.<\/p>\n","protected":false},"excerpt":{"rendered":"
