Winter Storm-Upstate NY-2/15-2/16


Recommended Posts

So the Euro was pretty much spot on with the track a week ago and other model guidance has hopped on board to a pretty similar track. It looks to strengthen as it heads up through Eastern New York into Canada.

Winter Storm Warnings are up for most of the forum.

 

This will be a large synoptic snowstorm for this region. Something we haven't seen in more than a year. Latest call for accumulations from KBUF.

I want to preface this on the basis that all models have thermal profiles built within them. This system will have lots of issues with mixing,rain,snow, ice depending on location and the generic snow algorithms output may be flawed depending on last minute fluctuations in track.

High Res Models

 

Tom Niziols post from facebook. This is his in house RPM model.

 

His post, "Wow!!! Newest RPM run shows 20-24" of snow for Buffalo. Some models show as much as 24-30" between Buffalo and Rochester. This is NOT a lake-effect snow event. It is a larger scale weather system that will track right up along the Appalachians."
