As Hurricane Season 2019 is winding down and temperatures start to hit freezing, the time has come for some forecasts and announcements for Winter 2019 – 2020.
Long-range climate computer models, including the CFS, the CanSIPS, and the NMME are indicating a slightly warmer, somewhat wetter winter season for the Northeast.
High temperatures are often in the mid 30s to mid 40s for much of December through February in the tri-state, with average lows in the 20s. This winter will, with a few exceptions, remain similar in trend and temperature.
There is one other, generally less well-known factor that contributes to Northeast winter weather, one that is especially vital in the development of intense Nor’easters: Sea Surface Temperature (SST). Once more, the CFS, the CanSIPS, and the NMME computer models are in agreement, with each model forecasting anomalously warm SSTs throughout the winter, particularly from January through March.
Warm water is an essential ingredient for the rapid intensification – the ‘bombing out’ – of Nor’easters often attributed to major winter weather events. A warmer than average ocean off the coast of the Mid Atlantic and New England can help contribute to these storms.
The National Weather Service – “Warmer than average for many, wetter in the North.”

Weather 360 at 5 Years: What’s New?
Last year’s roll-out of a self-developed statistical and data-driven approach to winter storm forecasting offered Weather 360 the ability to create Tri-State-specific weather forecasts. This year, new updates are being finalized to offer greater insight into snow accumulations, with an experimental focus on roadways and pavement to aid in forecasting driving conditions.
Weather 360 will issue Winter Weather Forecasts both here and on our Facebook page as soon as the first flakes start to fall.
