The Forecast

9PM Tuesday

No real changes this evening.
Snow continues to fall with about two inches now coating all surfaces in Kingston. Snow should continue steadily through the night. Snow tapers off tomorrow likely around 10AM or so as the system pushes off to our east. Looking for an additional 3 to 5 inches across most of Ulster county which should result in totals generally up to 7 inches. There really seems to be no reason why most, if not all, Ulster County schools shouldn't be closed tomorrow. Seasonable air behind tomorrow's storm will likely give way to increasing temperatures this weekend as we build up to our next storm. At the moment, the next one looks to be early next week (around Tuesday) and it looks like it'll probably be a lot more wet than white - but that's still a week out, so we'll discuss it later.

Enjoy the snow, and stay safe!


12PM Tuesday

The weather right now is like being in a snow factory. What I mean by this is we literally have an assembly line that has been working to produce snow for us since 5AM this morning, and will continue to go for another 24 hours.

The backbone of the assembly line is a frontal boundary that is draped across the eastern US. This frontal boundary is our conveyor belt. It is transporting packages of moist air from the south. And you can actually see it in the current radar - take a look:

So far this morning, the packages of moist air being transported by this conveyor belt have been steady, but actually pretty dry. The moisture has been just barely enough to produce some snow, so that snow has been very light (we've gotten about half an inch of snow over the past seven hours). But the conveyor belt is also transporting packages of air that are more moist. These more moist air packages will arrive locally this afternoon -by around 3pm. If you remember the update from last night, these are the packages of moisture that were initially expected to kick off the snow. Once the additional moisture arrives, we should see snowfall rates start to pick up a bit.

This will continue through about midnight. Around midnight a low-pressure currently developing off the North Carolina coast will start working on the conveyor belt. At that time, this low will basically walk along the conveyor belt splashing extra moisture into the packages. This extra moisture will help to increase our snowfall rates beginning around 2AM. This should all continue through the morning …say about 10AM or so… until the conveyor belt and the low shift off to our east. All-in-all this should result in about six inches of snow for the local area. And that's it - our snow factory!
