Happy Thanksgiving Wind Advisory Gusts Over 40 MPH Watching Storm For The Weekend
First off a spectacular and Happy Thanksgiving to all of you who regularly come to my websites, apps, videos etc. Even if you don’t come here daily or once in a while, Happy Thanksgiving and if you are new to the websites, apps, videos, etc, Happy Thanksgiving! Eat well and be happy. Lay the politics aside at least for the day.
Today it will be about the wind. We should see a fair amount of sunshine but there will be some patchy clouds in the mix and the wind will be cranking. Wind advisories are posted for New Jersey & Pennsylvania. The threshold for an advisory is borderline from NYC north and east but it is close enough. Most will see winds of 20 to 30 mph with gusts over 40 mph today. Low pressure is intensifying into a major storm east of New England and that storm moves to Newfoundland this weekend where it is going to sit for awhile and set the table for the next storm coming east from the Western US. Temperatures today will be in the chilly 40s and the wind will make it seem like it is in the 30s.
There isn’t much happening nearby but we do see on the regional radar rain showers in Southeastern New England from Rhode Island to Eastern Massachusetts moving southeast. The local Upton radar is picking up some of that precipitation to the east but there are no issues here for us as far as rain or snow showers are concerned.

We move on to a cold and rather breezy night ahead with clear skies. Lows will be in the 20s inland and low to mid 30s along the coast. Friday and Saturday it is about high pressure building down from Eastern Canada. Sunshine should dominate both days though we may see some arriving clouds later on Saturday.
The blocking low to the east and the high in Eastern Canada will allow cold air to slowly bleed southward so Friday night most lows will be in the 20s. Saturday with sun and arriving clouds, highs will reach the upper 30s and lower 40s.
While our weather is reasonably quiet at least half of the US today is under the influence of a large major winter storm in the Western US. Double digits snow amounts from California to the Plains and Rockies will be rather common. The blocking pattern that is set up will force the storm eastward where it will meet resistance in the Great Lakes and then attempt to redevelop right in our own backyard.
The atmosphere is going to be borderline cold enough for frozen or freezing precipitation into Sunday afternoon from Northern New Jersey to Southern New England so it will be a question of how fast the precipitation arrives while it is still cold enough. The storm redevelops close to us which pushes the warm air northward.
Follow the freezing line at 5000 feet from Sunday morning into Tuesday and you see the freezing line moves north of NYC Sunday afternoon and comes back south during Monday as low pressure develops to the east. My feeling at the moment is that we start as snow or a mix Sunday morning in most places and then see a change to rain from south to north. Ground temperatures inland may have a hard time climbing above freezing and we will figure that part out in time. After the first round of precipitation plays through it mpves out Sunday evening. It then redevelops later Monday as the cold air collapses. Here is where it gets a bit tricky because of where the low is (rather close by) and the cold air collapsing aloft. If we get intensity in the precipitation Monday afternoon and especially Monday night into early Tuesday than we could see it change to wet snow and accumulate just north and west of the coast. The European is especially bullish on this idea as it has a colder atmosphere than some of the other models. We plan on enjoying Thanksgiving day and after digesting a great meal, I will come back to this later today and explore the snow possibilities.
