A new study uses real mountain snow measurements and machine learning to give Western communities clearer and safer snowfall forecasts.

The varied topography of the Western United States—a patchwork of valleys and mountains, basins and plateaus—results in minutely localized weather. Accordingly, snowfall forecasts for the mountain West often suffer from a lack of precision,

While parts of the West are seeing a snow deficit this season, that hasn't been the case in snowy New England.

Northern US regions will face heavy snow, strong winds, and blizzard-like conditions, while the West Coast sees heavy rain and gusty winds from atmospheric rivers. The East Coast stays mostly calm with some inland rain and wet snow by November 27.

Swaths of central and eastern states have received much less snow than average over the past five winters – a trend that may continue this season.

Forecasters warn motorists that snow will pile up this week around the Great Lakes, with effects ranging from snow-clogged roads to downed trees and power outages.
