Colder weather has arrived, and more is on the way, but so is some rain.

The week starts off with low pressure pulling away from the region, with any lingering snow showers ending this morning, then skies start to clear out as high pressure builds in. Clear skies, lighter winds, and some fresh snowcover will result in radiational cooling tonight, with many places dropping into the teens. High pressure remains in control on Tuesday with sunshine and cool temperatures. An upper-level disturbance moves through on Wednesday, and it may be accompanied by some snow showers, especially along the coast. Even colder air settles in behind it for Wednesday night.

Clouds start to stream back in on Thursday as low pressure begins to head toward the region from the Southwest. For most of the region, this looks like a rainstorm for Thursday night and Friday, but a period of snow or wintry mix to start across parts of central Massachusetts and southwestern New Hampshire. However, this is still 4-5 days away, and a lot can change between now and then. Even small changes to the track that the low takes can have a big impact on the forecast. A track farther south and/or east could result in in wintry weather for a larger portion of the region and potentially for a longer period of time. We’ll be keeping a close eye on this as the week goes on. Behind the storm, cooler and drier weather returns next weekend.

Monday: Any lingering snow showers end early, then becoming partly to mostly sunny and breezy. High 33-40.

Monday night: Some clouds across the Outer Cape, otherwise clear and chilly. Low 16-23.

Tuesday: Plenty of sunshine. High 33-40.

Tuesday night: Mostly clear skies, breezy. Low 16-23.

Wednesday: Partly sunny and breezy, chance for a few snow showers near the coast. High 32-39.

Thursday: Becoming mostly cloudy, rain develops after midnight, possibly starting as snow or a wintry mix well inland. High 39-46.

Friday: Cloudy and breezy with periods of rain, possibly mixed with snow well inland. High 43-50.

Saturday: Rain may mix with or change over to snow before ending in the morning, becoming partly sunny in the afternoon, breezy. High 39-46.

Sunday: A mix of sun and clouds, breezy. High 35-42.

There’s a considerable amount of uncertainty in this week’s forecast, specifically the end of the week and next weekend, but even the first part of the week isn’t so clear-cut.

The week starts off with high pressure in control, resulting in a rather nice day by early December standards. Temperatures will start off cool, but with sunshine we’ll warm up nicely into the 40s in most spots. Clouds will start to stream in and thicken up during the afternoon and evening as a frontal system begins to approach from the west. Rain will develop during the day on Tuesday, but the temperatures are a bit of a question mark. Winds will shift into the southeast, allowing relatively milder air to move into parts of the region, but across the interior, the cooler air may hang on for quite a while. This is actually fairly typical for this time of year, and where the forecast models often struggle. They usually bring the warmer air in too quickly, but it often takes a lot longer than expected away from the coastline. This is more prevalent when there is snowcover, but it is not always necessary. The warmer air should eventually spread across the region Tuesday night and Wednesday, with highs on Wednesday getting into the 50s in many locations. The rain will continue Tuesday night into Wednesday as well, and while it may not be raining the entire time, some locally heavy rain is possible in spots. Rain eventually winds down Wednesday night as a cold front finally crosses the region, but it may not completely move offshore until Thursday morning. Skies may be slow to clear on Wednesday, and temperatures will turn cooler, but will probably still be above normal.

Friday and the weekend is where the forecast confidence goes right down the tubes. The upper-level pattern will begin to change, with a blocking pattern setting up. A strong area of high pressure will settle in over Greenland, with a broad upper-level low pressure system setting up over eastern Canada. Exactly where these features setup will have a drastic impact on our weather. In some cases, this setup can result in a rather stormy pattern across our area, but if the features aren’t in the right spot, then storms could mostly shift south of us, and we stay cold and dry. At various times over the past several days, the models have indicated that either scenario is possible. A low pressure system will move out of the Tennessee Valley and head toward the Mid-Atlantic states on Friday, moving offshore and then likely meandering around off the East Coast through the weekend. Is the storm far enough north initially to bring us some rain (or snow)? When the storm is hanging around during the weekend, will it impact our area at all? If so, what will those impacts be? These are questions that just cannot be answered at this time, as there is just too much uncertainty. We are fairly sure that temperatures will turn cooler as the pattern changes, but will they still be above normal, closer to normal, or even below normal next weekend? There’s plenty of cold air that’s been building up in Canada, but will it get in here next weekend, or will it move in during the following week? Again, at this point, we just don’t know. We should have more clarity on Thursday when we publish our Weekend Outlook.

Monday: Mostly sunny through midday, clouds start to move in during the afternoon. High 43-50.

Monday night: Increasing and thickening clouds. Low 31-38.

Tuesday: Cloudy with showers developing in the afternoon. High 49-56.

Tuesday night: Periods of rain and showers. Low 42-49.

Wednesday: Occasional rain and showers, ending at night. High 49-56.

Thursday: Becoming partly sunny. High 47-54.

Friday: Partly to mostly cloudy and breezy with a chance for showers. High 40-47.

Saturday: Mostly cloudy and breezy with a chance for snow or rain showers. High 37-44.

Sunday: Mostly cloudy with a chance for snow or rain showers. High 39-46.

Meteorological Winter begins on Thursday, but Mother Nature doesn’t want to bring us any winter weather anytime soon.

A cold front will cross the region today, and although it will have little moisture with it, it will bring breezy and cooler weather in for later today and into Tuesday. We’ll warm back up on Wednesday ahead of another storm system. That system passes to our north and west, with some rain likely late Wednesday and Wednesday night. As colder air settle sin behind the storm, some wet snow may mix in before the precipitation ends across the hills of central Massachusetts and southwestern New Hampshire. High pressure builds in behind that system with chilly weather for Thursday and Friday. We may warm up again on Saturday ahead of yet another cold front that could bring in some showers, with cooler weather returning on Sunday.

Monday: Some clouds around in the morning, becoming mostly sunny and breezy in the afternoon. High 48-55.

Monday night: Clear skies. Low 24-31.

Tuesday: A mix of sun and clouds. High 39-46.

Tuesday night: Partly to mostly cloudy. Low 28-35.

Wednesday: Mostly cloudy and windy with rain developing in the afternoon, ending at night, possibly mixed with some wet snow across the Worcester Hills and the Monadnocks. High 54-61.

Thursday: Sunshine and a few clouds, windy, much cooler. High 38-45.

Friday: Partly to mostly sunny. High 39-46.

Saturday: Partly to mostly cloudy, breezy, chance for some showers. High 50-57.

Sunday: A mix of sun and clouds. High 42-49.

Half of this week will be decent, and the other half may or may not be unsettled.

We’ve got high pressure in control for the next few days with generally dry weather and moderating temperatures. A weak frontal system moves through late Wednesday with little fanfare, but it will bring some cooler air back in for Thanksgiving Day. We’ll also see clouds stream in on Thanksgiving as low pressure begins to make its way up the East Coast. This is where things become very uncertain.

The models have been consistently inconsistent with this storm. They never seem to agree with each other, and they change their tune on nearly every run. Sometimes it’ll look likely a coastal storm with strong winds and heavy rain, and possibly a wintry mix across the interior, some runs the storm goes up to the west of us, so we get rain and milder temperatures, some runs it’s a coastal storm well offshore and a weaker system moving across northern New England with just a few showers. Some runs have the storm Friday, some Saturday, and now, some even have it on Sunday. At this point, it’s just too early to nail down any details. What you’ll see below is our best guess at this point, but really, we could just write in “Partly to mostly ____ with a chance of _____”, and that would probably cover it too. We should have more clarity when we post our Weekend Outlook, which will be done on Wednesday this week instead of Thursday due to Thanksgiving.

Monday: Sunshine and a few clouds, breezy. High 36-43.

Monday night: Clear skies. Low 26-33.

Tuesday: Sunshine and some afternoon clouds. High 40-47.

Tuesday night: Clear skies. Low 26-33.

Wednesday: Plenty of sunshine. High 44-51.

Thursday: Morning sun, then increasing and thickening clouds. High 41-48.

Friday: Mostly cloudy with a chance of rain. High 47-54.

Saturday: Partly to mostly cloudy and breezy with a chance of rain. High 47-54.

Sunday: Partly sunny, breezy. High 45-52.

As we flip the calendar to November, it certainly won’t feel like the final month of fall for a good portion of the week.

We start the week off with low pressure moving from the Tennessee Valley into the eastern Great Lakes. It will spread clouds into the region today, with a few showers likely tonight into early Tuesday. Once that system moves by, high pressure builds in with drier conditions for Wednesday right through to Saturday. Temperatures will be mild for the most part, and next weekend could see temperatures get into the 70s away from the coastline. By Sunday, a cold front will drop down from the north with some showers, but temperatures will be dependent on the timing of the front. The later it moves through, the more likely it is that we have another warm day.

Monday: Plenty of clouds with some sunny breaks at times. High 60-67.

Monday night: Mostly cloudy, chance for a few showers. Low 50-57.

Tuesday: Chance for a few showers early, some clearing may take place late in the day. High 62-69.

Tuesday night: Becoming clear. Low 48-55.

Wednesday: Plenty of sunshine. High 61-68.

Thursday: Sun, sun, sun! High 56-63.

Friday: Partly sunny. High 62-69.

Saturday: Intervals of clouds and sun. High 65-72.

Sunday: Partly to mostly cloudy with showers possible. High 65-72.

Over the past few months, we’ve had numerous weeks during which we have enjoyed extended stretches of dry weather. The first half of this week won’t be one of them.

A weak low pressure system moving up from the south will bring in more showers today, tapering off to drizzle this evening. Occasional showers may linger into Tuesday and Wednesday as an upper-level system moves in from the west, before a cold front finally moves across the region. Drier air moves in for Thursday, but temperatures will remain warm. High pressure then builds in for the end of the week with drier and more seasonable conditions.

Monday: Cloudy with occasional showers and fog. High 59-66.

Monday night: A few more showers along with some drizzle and fog. Low 51-58.

Tuesday: Plenty of clouds with a shower or two possible. High 64-71.

Tuesday night: Cloudy with a few showers, more fog may develop. Low 55-62.

Wednesday: Scattered showers. High 61-68.

Thursday: A mix of sun and clouds. High 64-71.

Friday: Partly sunny and cooler. High 52-59.

Saturday: Intervals of clouds and sun. High 53-60.

Sunday: Partly sunny. High 56-63.

We’ve got a couple of nice days coming up, and a couple of not-so-nice days coming up.

High pressure remains in control through Saturday with sunshine both Friday and Saturday afternoon along with moderating temperatures. So, if you’ve got outdoor plans, you’re in good shape. Clouds will start to move in from the south late Saturday and Saturday night as low pressure starts moving up the coastline. This will be a fairly weak storm, but it will have plenty of moisture. Rain will develop during the day on Sunday, likely reaching the South Coast during the morning, the Mass Pike corridor by early afternoon, and the Merrimack Valley and Southern New Hampshire by late afternoon. Sunday night will be fairly wet, as the rain may be heavy at times. On Monday, the rain will taper off to showers during the morning, with the steadiest rain ending by early afternoon. However, occasional showers and drizzle may linger well into the evening, which could make for a damp night in Foxborough for the Patriots Monday Night Football game with the Bears.

Thursday night: Clear and chilly again. Low 36-43.

Friday: Plenty of sunshine. High 57-64.

Friday night: Clear skies. Low 37-44.

Saturday: Sunshine through early afternoon, then high clouds start to stream in. High 61-68.

Saturday night: Increasing and thickening clouds. Low 41-48.

Sunday: Rain developing from south to north. High 57-64.

Sunday night: Periods of rain, possibly heavy. Low 47-54.

Monday: Rain tapers off to showers early, showers drizzle through the afternoon. High 59-66.

The week starts off unsettled, but a warmup is in the way.

A strong cold front will approach the region today, with some showers developing ahead of it. Those showers will continue off -and-on into Tuesday morning before the front finally pushes offshore. It does not look like we’ll have the heavy rain that the models were advertising a few days ago, but any rain will help to continue to put a dent into the drought. Skies start to clear out late in the day as high pressure starts to build in. While temperatures will turn cooler for Tuesday and Wednesday, the core of the cold air will stay off to our west. In fact, some lake-effect snow is possible downwind of the Great Lakes over the next few days. We’ll have temperatures that are below normal, but highs should still be in the 50s. By the end of the week and the weekend, the high slides off to the east, allowing temperatures to moderate to above normal levels for Friday into Sunday.

Monday: Mostly cloudy, showers develop in the afternoon. High 57-64.

Monday night: Cloudy with occasional showers. Low 46-53.

Tuesday: Showers ending by early afternoon, gradual clearing late in the day. High 56-63.

Tuesday night: Becoming clear. Low 34-41.

Wednesday: Sunshine and a few clouds. High 51-58.

Thursday: Plenty of sunshine, breezy. High 50-57.

Friday: Mostly sunny. High 56-63.

Saturday: Sunshine and some afternoon clouds. High 62-69.

Sunday: A mix of sun and clouds. High 63-70.
