DAYS 1-5 (DECEMBER 6-10)

The pattern during the next 5 days will feature several quick-moving, generally weak low pressure systems to have minor impact overall (in terms of precipitation) but some notable temperature swings with the overall pattern being colder than the long-term average for this point in the season. The first such system is a low pressure area passing well to our south today but its large cloud canopy making it mainly overcast. A northward-extending trough from that low will cause a few snow and rain showers in the region this morning until about midday. The next system will be a clipper-style low passing just to our north Sunday night. This low will have a snow area with it but its track keeps it mainly north of the WHW forecast area, with just a few snow showers occurring mainly to the north of I-90 on Sunday night. Another weakening system flies north of the area Tuesday evening with a remote chance of a snow shower that will favor southern NH with less chance to the south. A slightly more formidable low pressure area, again clipper-style, will head our way via the Great Lakes on Wednesday. The early indications on this are a track to the north, enough to pull milder air into the region making the precipitation, still minor, more likely to be rain showers than snow showers for our region.

TODAY: Mostly cloudy. Scattered snow showers I-90 region northward and mix / rain showers south of I-90 until midday. Highs 35-42. Wind variable up to 10 MPH becoming mainly W.

TONIGHT: Clearing. Lows 18-25. Wind W up to 10 MPH becoming calm.

SUNDAY: Sun followed by clouds. Highs 34-41. Wind SW 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Scattered snow showers southern NH and northern MA, isolated snow showers to the south. Lows 13-20. Wind shifting to NW 5-15 MPH with higher gusts.

MONDAY: Mostly sunny. Highs 25-32. Wind NW 10-20 MPH, diminishing.

MONDAY NIGHT: Clear. Lows 8-15. Wind NW under 10 MPH.

TUESDAY: Sun followed by clouds. Highs 28-35. Wind N up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. A snow shower possible favoring southern NH. Lows 20-27. Wind SW 5-15 MPH.

WEDNESDAY: Mostly cloudy. Increasing chance of mix to rain showers. Highs 38-45. Wind S 5-15 MPH.

DAYS 6-10 (DECEMBER 11-15)

Reinforced cold arrives to start the period along with wind. Watching one or two clipper-style low pressure areas for mix/snow chances mid period before dry, cold weather returns at end of period.

DAYS 11-15 (DECEMBER 16-20)

Guidance trends have been wish-washy the last couple days – basically no help for this period of time. Expectations for indices that tend to control the pattern as well as little use of forecast persistence (old forecast tool I learned as a novice) leads me to not change things too much at this point. I’ll watch for a potential low into the Great Lakes and a brief warm-up, then the region near a battle zone between mild air to the south and cold from Canada, the latter of which probably ends up winning out, and not without a precipitation potential before the end of the period. Lots of time to solve the pattern puzzle here…

  4. Good morning and thank you TK

    31 here after low of 27 which was shortly after midnight as the temperature slowly climbed all night long.

    Ocean: 48 (Boston Buoy)

    I think TK described my feelings about the upcoming weather:
    WISHY WASHY!! Not impressed with anything. and the cold, what there is of it, has NO lasting power at all. All this talk of the polar vortex has been a joke as far as I am concerned.
    The cold of yesterday, although cold for sure, was extremely short lived. Polar Vortex, is that all you can do. WIMP!!

    And the parade of clippers, must they ALWAYS pass NORTH of our area. Seems that way, even though on occasion they pass South of us. WHY, oh WHY can’t we have one of those? I guess it’s not in the cards, not yet anyway. We shall see down the road.

    Wordle: 4 I wasted a guess on guess 3. Should have had it in 3 as guess 3 didn’t provide any more information.

    1. They are not all going to pass north of the area. The next 3 are. There are several others in the pipeline after that with a pretty strong indication that the track is not going to stay where it will be the next 5 days.

    1. Nice! The snow falling looks much like it does here. That’s not surprising since it’s just 11 miles from me.

  9. Thank you, TK. A lot warmer last night with a low of 24. Up to 27 with a sugarcoating here also. I like that term.

  10. What’s the difference between sugar coating and feather dusting?

    Is sugar coating just a wee bit thicker??? 🙂

  13. Thanks TK! My daughter landed in Sydney, Australia this morning where temps have been in low 90s in their late spring. A line of heavy storms had just gone through leading her plane to circle for awhile. Now they have a cool SOUTH wind coming in that will lower temps for the week. She will be there the next 7 months long enough to see Australia play the US in the World Cup. How lucky is she that they ended up in the same pool!
