Some snow possible this evening, but wind and cold definite for Wednesday

There are snow maps out for southern New England today, but don’t get too excited. While it may look somewhat wintry later this afternoon and evening, I don’t expect much in the way of accumulation.

Storm Develops to the North
The problem for snow lovers—and the saving grace for those who don’t want to shovel—is that this particular storm will develop too far north as it affects the region. If you are heading into southern New Hampshire or Maine this afternoon and evening, however, driving will be difficult due to moderate snowfall. There are winter weather advisories and warnings in that part of New England.

Timing of the Snow & Rain

I expect an area of snow and rain to push eastward between 4 and 6 p.m. Temperatures, while cold during the morning, will warm above freezing this afternoon. This means the precipitation will begin as rain or a mix of rain and snow.

The radar loop below is a forecast through mid-evening. Notice the green area, indicating rain, is along the coast and points south with the darker blue area—snow—inland. The darker color represents some bursts of moderate snow appearing around 8 p.m.

The precipitation will likely impact the evening commute, but we should eke out most of the drive before the roads would become icy. If you are driving after 7 p.m., especially inland, be aware that slick spots should develop around that time.

As the precipitation comes down hard, it will change to all snow away from the coast and begin to accumulate. Generally, expect between a coating and an inch to fall, with the highest totals inland and north of the Massachusetts Turnpike heading into New Hampshire. There could be a few spots with two inches of accumulation tonight, but they will be the exception.

The snow will wind down by about midnight followed by clearing in the morning. What falls overnight will be frozen solid tomorrow.

Windy Wednesday
Speaking of Wednesday, the wind and the cold will be the big weather story. I expect temperatures in the 20s and wind gusts to exceed 30 miles per hour.

The wind subsides Thursday, and there will be a recovery from the cold on Friday. Another storm looks likely Saturday, but the track and strength of the storm will determine what type of precipitation you receive.

Weekend Storm

Presently, it appears to be a rain storm at the coast, with snow inland and up north. This could end up being a fairly significant snowstorm for the ski areas, which could use some snow. The models have been forecasting a storm for this coming weekend for nearly 10 days. Unlike last winter, when cold air was so readily available for most storms, the coldest air is not here in New England. Therefore, rain remains a possibility in each of these storms.

I’ll send out tweets during this afternoon and evening as the snow develops and progresses. Please follow me @growingwisdom.
