Light snow has tapered off to scattered snow showers for most of the region. The exception being the upper Hudson Valley and the Catskills. For the majority of the viewing area, the accumulating snow has ended.
Final snowfall totals seem to range between 18 and 24 inches on average… with parts of Rockland and Westchester counties coming in at 12 to 18 inches thanks primarily to the changeover to sleet that occurred.
We are seeing some delays and cancellations come in for Wednesday already, as cleanup operations begin. Expect clouds and scattered snow showers to last into the night, with maybe a coating to a half inch additional accumulation. Temperatures will plunge into the low teens tonight, with wind chills near zero, so be sure to bundle up if you’re going to get a jump on the cleanup tonight. We’ll also see some gusty winds tonight, and again on Wednesday, as the storm departs, so expect some more blowing and drifting snow as well.
Please leave snow totals in the comments as well, as we try to recap the full impacts of the Blizzard of 2017. Thank you so much for all the information you provided us today, allowing us to better track the storm… and thank you for trusting HVW as your local weather resource. Stay warm, be safe if you must travel this evening, and have a nice night.
4pm Update: The heaviest snow, at rates of 1 to 3 inches per hour… has moved north of the Hudson Valley. But the back edge of the snow continues to pivot slowly over the Hudson Valley… providing us with areas of light to moderate snow across the region as of 4pm.
The worst of the storm has now moved to our north, but this back edge of snow could still drop another 1 to 3 inches before tapering off this evening. We will continue to see strong NE wind gusts over 30mph. So despite the lower snowfall rates, there will be tremendous blowing and drifting of snow, which will create reduced visibilities. Travel is still not advised.
We will continue to have updates, however we have lost internet, and are working off or phones the rest of the way. So please bear with us.
12pm Update: Heavy snow continues across much of the Hudson Valley at this hour, but we’re seeing a bit of dry air work northward into the Hudson Valley. This hasn’t shut the snow off entirely, but it has lessened the snowfall rate in many areas. We expect that this dry air will fill back in on radar, as the snow shield rotates around this strengthening system. So just because the snow has tapered off a bit, does not mean the storm is over by any stretch.
We also …have reports of sleet in the lower Hudson Valley, mainly in Rockland, Westchester and Putnam counties. Those areas likely will see periods where it changes to all snow, then back to sleet, and so forth… as the milder air in the mid levels of the atmosphere works itself through the region. Ultimately, a change over to all snow is expected as the storm deepens and pulls east.
In addition, the winds are howling out of the northeast at 10 to 20mph, frequently gusting over 35mph. This is causing tremendous blowing and drifting of snow, and reducing visibilities under a 1/4 mile in many places. It’s the true definition of a blizzard across the Hudson Valley today.
We need your reports to keep coming, so we can monitor the progression of the Blizzard of 2017. Stay warm, and be safe! Thanks for all your information and feedback!
A Blizzard for the ages continues to thrash the Hudson Valley at this hour. Snowfall totals region wide appear to be nearing of over 12″ from I-84 on south (where it has been snowing longest), and between 6 and 12 inches north of there. Winds gusting over 25mph out of the NE have been blowing and drifting the snow as well.
We are now entering the height of the storm. Look at this radar… snowfall so heavy, it is off the scale, appearing as red. Snow…fall rates under these red bands, would be 3 to 6 inches per hour. Thundersnow is also likely within that band. That band is currently in the lower Hudson Valley, and will continue moving northward over the next hour or two. White out conditions are expected, as we see snowfall rates exceed 3 inches per hour at times. Simply put… do not travel, unless it’s an urgent emergency.
One of the issues we want to address, is some other outlets lowering snowfall totals for the southern Hudson Valley, due to the expectation of sleet mixing in. We would not be surprised if sleet mixes at times near I-287, and near I-684 later this morning and early this afternoon. However… snowfall rates will be so intense, the impact on total accumulations should not be substantial. It’s the difference between 20 and 30 inches in all likelihood. Where sleet mixes… final totals will be closer to 20″… where it doesn’t, totals could surge toward (or even exceed) 30 inches.
Over the next 4 hours, we’re going to experience weather that you only see once or twice in a lifetime across the Hudson Valley. Make sure you stay safe, and are extremely careful clearing the snow. It’s a light, fluffy snow… but there is already a foot of it in spots, so pace yourself shoveling. We don’t want anyone getting hurt out there. Updates will continue through the day…

The Blizzard of 2017 has already put a hurt on the Hudson Valley as of sunrise.
Widespread snowfall amounts between 4 and 8 inches of snow so far in the region. A tremendous amount of moisture continues to advance from the southwest, all the way down into Virginia. This storm has only gotten under way, we have a long way to go. Snowfall rates of 1 to 2 inches per hour will continue the rest of this morning…. Please don’t travel if you don’t have to.
Here we go… snow is on the doorstep. This system is already deepening rapidly. The center of low pressure is in southern North Carolina at this hour, to give you an idea of just how large this system is. The finger of precipitation is now reaching into the southern half of the Hudson Valley… about an hour or so ahead of schedule. Most areas from I-84 on south are just seeing some flurries… but a few coatings are already being reported in Rockland and Westchester counties.
Expect this band of snow to continue pushing northeastward over the next few hours. Snow will begin light… but become steady rather quickly, as there is ample moisture already pushing into the valley. Conditions will deteriorate overnight, and by morning… guidance is suggesting snowfall on the order of 3 or 4 inches for our northern viewers… and up to 7 or 8 inches closer to the NY/NJ border. So even before sunrise on Tuesday, a significant snows are expected. Snowfall rates will increase through the night, and into the morning on Tuesday… peaking toward mid day on Tuesday.
If you’re still wrapping up preparations for this storm… your time is running out. Anyone planning to travel overnight, please use caution. We’ll have updates and discussions the remainder of the way. Please be safe everyone…
