DAYS 1-5 (DECEMBER 20-24)

On this final full day of astronomical autumn, we’ve lost the short-lived feeling of spring we had yesterday and returned to the feel of winter. Well, that covers everything except summer. 😉 Seriously though, we have seen the return of colder air, but not the degree of cold we experience for much of the first half of December. We’re now in a pattern of up and down temperatures, and while the “ups” in the coming days are not going to feature the springlike readings of Friday. We’ll see this shown by the fact the next low pressure area to impact our region is this weekend, and we’ll see high temps in the 30s today and over 40 Sunday in the warm sector as the low passes by to our north. This will be a moisture-starved system, and while I previously highlighted the slight chance for insignificant precipitation, I’m removing that from the forecast this weekend in favor of dry weather – just a variety of clouds with the warm front / cold front combo with the passing low pressure area. The departure of this one does pull some colder air in again for Monday, setting the stage for a snow/mix/rain event on Tuesday as the next clipper low moves through. There are still some finer details to work out with this one, like precipitation-type and more precise timing. It will not be a big event but it does have the potential to have some pre-Christmas travel impact. Whatever it has in store for us, off it goes Tuesday night and sets up a mostly dry, seasonable Christmas Eve. We will have to watch for a weak disturbance that can cause a quick snow shower that day or evening. The winter solstice occurs on Sunday morning at 10:03 a.m. EST.

TODAY: Sun followed by clouds. Highs 35-42. Wind W to SW 10-20 MPH, higher gusts.

TONIGHT: Variably cloudy. Lows 23-30. Wind SW 5-15 MPH, higher gusts.

SUNDAY: Partly sunny. Highs 40-47. Wind SW to W 10-20 MPH with higher gusts.

SUNDAY NIGHT: Partly cloudy. Lows 21-28. Wind W to NW 10-20 MPH.

MONDAY: Mostly sunny. Highs 30-37. Wind NW 10-20 MPH, diminishing.

MONDAY NIGHT: Clear early, clouds return later. Lows 23-30. Wind S up to 10 MPH.

TUESDAY: Cloudy through midday with a period of snow/mix north, mix/rain south. Variably cloudy with late-day snow/mix/rain showers possible. Highs 35-42. Wind variable 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 18-25. Wind variable to NW 5-15 MPH, higher gusts.

WEDNESDAY: Variably cloudy. Slight chance of a passing snow shower. Highs 32-39. Wind W 5-15 MPH.

DAYS 6-10 (DECEMBER 25-29)

Up-and-down temperature pattern, leaning toward slightly below normal with a couple disturbances potentially bringing mostly minor precipitation events – storm track trend favoring them passing to our north in the expected large scale pattern.

DAYS 11-15 (DECEMBER 30 – JANUARY 3)

A similar pattern – a couple smaller low pressure systems with mostly minor impact, but causing variable temperatures, but near to slightly below normal for the period overall.

  3. Thanks TK
    Fingers crossed Tuesday could leave some snow on the ground and there will be a little left on Christmas morning.

  4. Good morning and thank you TK.

    31 here and that was the low

    Ocean: 46

    models are showing about 2 inches for Tuesday. If it goes to rain, how much will be left?

    Wordle: 2
    1ST guess yielded last 2 letters in position. Then it was trying various combinations in my head and then in that process it just came ot me.

    I seem to be all over the place with this game.

          2. Not that one.

            It could be snowing at 7:00 a.m., heavily, with 0.4 inch on the ground, and 0.5 inch at 7:01 a.m., continue to snow heavily all day. And yet that would not be considered a white Christmas.

  6. Finished watching a new series on Netflix called Ripple.
    I really liked it. It’s kind of like a mixture of This is us and Love Actually. Characters are amazing and is very well done.

    IMHO, well worth a look.
    Your mileage may vary.

  13. Thank you, TK.

    We are 30 from a low of 28.

    Sad day yesterday, undoubtedly caused by our crazy weather swing. A 92 year old lady who my daughter had worked with in the past and recently was reacquainted with had the 27/28 yr old horse that she foaled boarded at a nearby facility . She was still able to drive to be with her horse every day. Same time.

    Longer story short. The horse coliced yesterday. Horses can’t throw up so colic can be bad. In this case it was. She didn’t survive tufts attempt at surgery.

    There is really no way for most folks to know how drastic weather changes…temps especially….can have on animals. Just a fact of life. But can be so sad.

    This shows that there will be boundary layer issues right along the coast with pretty low ratio snows.

    But overall, this is the most robust yet!! TOO BAD it is the GFS. 🙂 🙂 🙂
