Winter Storm Recap – 12/1/2019 – 12/3/2019

We definitely kicked off the 19/20 winter season with a bang.  An extremely complex winter storm impacted the Hudson Valley over nearly a 36 hour period in many places, and when all the snow flakes settled, we saw anywhere from 2 or 3 inches in parts of the lower HV… to over 2 feet of snow in the Catskills.  Here are a series of maps we shared on Facebook earlier, followed by a short discussion.  We’ll start with our forecast and compare it to what actually occurred, and snow totals from the NWS.

A fascinating range of snowfall amounts were observed around the region.  From 2 inches in Nyack… to 25 inches in East Jewett.  When dealing with a long duration event, especially one where at least 50% of the snow in most areas came in hours 30 to 36 of the event… a lot of people gave up on this storm, calling it a bust.  We tried to highlight throughout the forecasting of this event, that much of it would be on the back end of the system… and that surprises would be common.

When all was said and done, we were pretty close with our forecast.  The areas we did worst (and we’re nit picking), were really in the northern and eastern HV.  In parts of SE Dutchess county… we were on the low end of our range, with a lot of 7″ amounts in the 6 to 12 range.  And then in Putnam county, our 4 to 9 inch range saw a lot of 4 and 5 inch amounts.  The reason being sleet was the dominant precipitation type on Sunday, and the snow was late to fill in over these areas Monday night.  But we got where we need to be.  Then the upper HV… we just didn’t go high enough in some areas.  Upper zone 3 and 4, were in the 6 to 12… but we saw a lot of 12 t0 18 inch totals in the northern most areas.  We had tried to indicate that some 12+ were possible in those regions… but they overachieved, due to the first wave being mainly snow for many… and piling up 5 to 10 inches on Sunday alone, then the snow just never stopped in some areas, as the storm pivoted on Monday.  Albany saw this storm become a top 10 event!

But for most areas… this complex system was forecasted very well.  A nice way to kick off the winter season.  Here are some final maps from the different departments of the NWS.  Thank you for all your support of HVW.  It means the world to us!  Have a great weekend!!

  1. This was my first storm with HVW. Not that I am looking forward to the next storm I am looking forward to HVW getting me through it. THANX.

  2. Re: Spencertown, I was wondering about that, too. I’ve gone over maps of the area to the east and northeast of the east end of the Ashokan Reservoir, and don’t see any place-name (or road) “Spencertown”. The land there is slightly elevated compared to its surroundings, but not enough to get that kind of snow. I’m beginning to suspect that it was a typo or transcription error — 22.5 inches reported instead of the actual 12.5 inches. I got 14 inches here in Wittenberg.

  3. I live right on the Woodstock/West Hurley border. I didn’t physically measure, but it looked like 6″ at most. I’m already starting to see the grass again. It barely snowed at all Monday. The roads were clear, and I went to work like it was a regular day. Whatever snowing it did do didn’t accumulate because it was so wet. I was keeping a close eye on the radar throughout, and there was almost always a weird gap in the storm right over my area. Yay for me!
