Our nor’easter has arrived this morning and is progressing more or less as forecast.
Radar imagery and observations from the surface show a band of very heavy snow extending from Albany NY through southern NH into York County ME as I write this around 6 AM. Snowfall rates in this band have been measured between 2-3″ per hour and there were even signs of thundersnow near Keene! I think this band has reached its “high water mark” as far as latitude goes over NH but probably has another 20-40 miles to come north into the Maine coast.
The leading edge of the snow has pushed into northern NH and parts of central Maine though dry air is still holding strong northeast of Lewiston. This trend will likely continue through most of today even as our storm (and its associated forcing for snow bands) moves northeast. I still like the Fryeburg-Lewiston-Camden corridor as the northern edge of sustained heavy snow but perhaps we might end up a smidge farther north than expected.
This is the snowmap I posted yesterday evening, and I’m still feeling pretty good about it.
The heaviest snow will fall between now and noon before tapering off from west to east this afternoon.
Temps will remain quite chilly throughout the day, ranging from around 15 up north to perhaps as high as 20 in southern NH.
Remember to watch out for blowing/drifting snow throughout the storm and even for a while this afternoon after most of the accumulating snow is done.
