There’s apparently a Nor’easter brewing for this weekend, although there’s not a ton of cold air around for the system to use, so the current forecast suggest snow will only be up near the summit elevations and fairly limited in amount.
“…once the snow showers got started in the morning, they literally kept going all day with that classic upslope flow from the northwest..”
This event was the second accumulating one at our house this month, and the fourth one for the mountains. Looking ahead, there seems to be some potential for snow in the midweek timeframe, and then again out toward the weekend.
“The data suggest that our first snow of the 2018-2019 winter season from this past Saturday (October 13th) is a few days on the late side of the mean for first accumulating snow (October 10th), but overall quite typical.”
There are a couple of seasons that I couldn’t include in the statistical analysis because of gaps in the data collection early in the co-op site’s history, but there were still 62 seasons in the data set that provided useful information. The data suggest that our first snow of the 2018-2019 winter season from this past Saturday (October 13th) is a few days on the late side of the mean for first accumulating snow (October 10th), but overall quite typical. The full results from the statistical analysis are below, so have a look and think snow!
“…it looks like we’ll have more opportunities for snow this week with accumulations potentially even down to the mountain valleys.”
Here at our house, I did a morning check to find that the cloud ceiling was still only about 2,000 feet and there were no obvious signs of snow below that level. I gave the clouds some time to think about clearing a bit, and then headed out in the neighborhood during the mid-afternoon period to see what snow might be visible. Indeed the cloud ceiling had risen by about another 2,000’ and I was able to catch Camel’s Hump as the clouds had just about broken away. The snow line at that point looked to be around 3,000’.
After our big autumn storm that brought substantial wind and power outages to Vermont (including our house), cold air came into the area today and brought one last snowfall for the month on Halloween. Powderfreak is out of town, but his colleagues at Stowe kept him apprised of what was going on at the mountain with pictures of the fresh snow.
As is typical for this type of weather setup with a flow from the Great Lakes, the areas around the mountains often get the most vigorous precipitation, which can lower snow levels down to the valleys. I wasn’t home during the day to see if anything frozen fell at our house, but I wouldn’t be surprised if we got something.
It’s interesting to note that if we hadn’t picked up any frozen today that would have been the first time in the 12 years we’ve been at this location that we didn’t get any frozen precipitation in October. So that streak continues for now, but it’s still 12 days later than the mean, and of course it’s the latest “first frozen precipitation” we’ve seen here. I guess with as warm as this October was, it’s nice to even get anything frozen, and at least the snowfall season is officially underway here.
Now it’s on to November, with more substantial chances for snow growing by the day.
We’ve had plenty of pleasantly benign weather days this month, but yesterday was one of those raw October days that really speak to the seasonal progression. Temperatures in the valleys even stayed well down in the 40s F, and a storm passing through the area brought bouts of heavy rain that made walking around outside a rather rough experience. I wasn’t sure if this storm was actually cold enough to bring in some snow to the area, but sure enough, Powderfreak was already posting snowy images from Mansfield this morning and letting us know that the snow level was down to 3,000 feet. Once the clouds began to break away from the mountains in the afternoon I was able to snap an image from my office of the new white near the peak of Mansfield behind some of the colorful foliage still hanging on in the Champlain Valley. We’ve got a potent storm coming into the area Sunday that is expected to bring a lot of wind and rain, and next week there’s the chance for a bit more snow in the area as we get some cooler temperature and a flow that could bring moisture over from the Great Lakes.
