Today will feature the calm before the storm here in Northern New England as we have about 24 hours to go until snow begins to crank up in advance of an ocean low moving up the coast. Temps today will be much warmer than recent days, with highs soaring into the 10’s for most, and even getting into the low 20’s for SE NH. There will be a mix of sun and clouds today, with clouds slowly taking over as we head into the evening.
Our storm will rapidly intensify off the Florida coast this afternoon before racing NNE tonight. Expect snow to begin in the early morning hours in Southern NH with Portland seeing flakes by 7 or 8. By 10 AM, everyone should be seeing at least light snow. As we move towards noon, intense bands of snow will rotate in off the ocean, bringing 2-4″ per hour snowfall rates, wind gusts to 65 mph along the coast, and blizzard conditions. These bands will continue to impact mainly eastern parts of the region through the evening, before snow tapers off overnight.
Here’s an animation showing the 24 hour evolution of our storm from tonight through tomorrow night according to one model’s forecast. While I don’t have faith in the model’s placement of any given band, it does do a good job highlighting the overall setup. The animation is from weathermodels.com, our new subscription service from weather.us. Try it out for free until January 25th if you’re interested!
For a full breakdown of the storm and its impacts, check out my latest two weather.us blog posts. The first one (from 1/1) discusses the overall setup and some of the meteorology behind the storm itself. The second one (from yesterday) discusses each of the storm’s impacts from freezing rain in Florida to our blizzard here in Maine, along of course with some analysis of what’s driving each impact and why I’m expecting what I am.
