Before we begin, I want to say thank you to everyone who has sent well wishes my way. As you know, I’ve been absent for a few weeks to deal with very busy and uncertain times, but I want you to know that everything is fine and I’m ready for winter! We’re just a few days away from my first two week outlook!
Last time I wrote, it was October 30th. I provided a quick outlook for November, and I can only hope that I’m as accurate as I was then:
This November, I don’t see either dominating, at least in the first half of the month. I think that overall, we’re looking at a typical gradual step-down toward winter in Connecticut, with short and frequent oscillations between warm and cool early in the month, a transitional period that leans more directly toward below normal temperatures in the middle, and a more deliberate move toward colder than normal conditions in the last week to ten days of the month. I think that the long range ensembles, which are currently hinting at a push toward colder conditions by the middle of the month, may end up being a bit too fast with a quick change to consistent winter-like conditions.
That wasn’t a bad call. There were short and frequent changes in the early part of the month, but the last ten days have featured pretty warm temperatures instead of a period of below normal temperatures. The last part however, looks to be more accurate. The models did bring the arrival of winter too soon, and now, right on cue, the last ten days of the month are going to look and feel like winter.
Hopefully you enjoyed today. Winter is coming. Let’s start with our SCW period of interest—tomorrow and Monday.
Sunday will begin with the cold front pushing through the state. With warm temperatures aloft and at the surface, we will see everyone start with rain. Over the course of the overnight hours however, the northwest hill towns and other portions of western Connecticut will see the temperatures aloft drop enough to change things over to a brief mix and then snow. I expect this to be a relatively brief period of steady snow, but the guidance has been more bullish recently. Even without a steady thump all day, we should see on and off snow showers through much of the day in western and northwest Connecticut, any of which could drop a quick coating if it falls quickly enough. For the northwest hill towns however, I am more concerned that we’ll see accumulating snow early on. It doesn’t look plowable, but I think with the combination of dropping temps and snow the roads will be slick. Take it easy out there tomorrow morning.
Monday looks to be the best day for the rest of the state to see snowflakes, as brisk northwest flow brings the chance of snow showers. It will be windy and cold, bringing wintry appeal even if there isn’t much accumulation from this second round of snow. Wind chills Sunday and Monday will make it feel much colder than it actually is.
Let’s take a look at what some of the guidance is depicting.
18z 4km NAM
Note--the latest NAM came in very bullish. I'm not buying it right now, but I do think there is bust potential here.
- I’m going with with a coating to an inch in the lower elevation locations in Litchfield and northern Fairfield Counties. I have a lower confidence area of coatings to an inch in the higher elevations of eastern Connecticut.
- I expect 1-3 inches in the higher elevation and further north locations in Litchfield County, with an outside chance that a location or two lollipops higher than that.
- For the rest of the state, there is a greater chance of snow showers as cold air advects in on Sunday and we see snow showers through Monday. I'm not expecting a lot of accumulation outside of a coating. Though some spots could get lucky under a heavier returns. Regardless of where you are, it’ll feel like winter.
Although relatively isolated, given the snowfall potential in the northwest portion of the state, we are issuing our first map of the season.
This period looks cold, dry, and boring, so not much needs to be said. The wind should die down and we’re looking at a period of below normal temperatures, though by Wednesday we’re warming up and watching the next storm, set to arrive just in time for Thanksgiving.
Thanksgiving & Weekend
By Thanksgiving Day, we’re likely seeing a storm cut well to our northwest, but there could be some redevelopment off the coast on Friday. Right now, all I can confidently say is that there has been a signal for a storm for a while now, but the evidence suggests that this is just a rain event.
There is the chance that enough cold air is in place early on to bring a brief period of snow or mixed precipitation though before a changeover to rain, but that seems like a low probability deal right now. Stay tuned in case things change.
The weekend looks nice and mostly dry right now. We’ll be watching for the chance of a weak low crossing the region on Saturday, but I’m not concerned about that at all right now.
We’ll be around for updates if they are needed tonight and tomorrow. Send us your reports and pictures! They are helpful and might even be featured here on our Facebook page and Twitter @SouthernCTWX.
