Snow will be widespread from northeastern Connecticut through much of Maine. This snow will extend back into some of the higher elevations in New York. Colder air is moving closer to the coast, allowing for rain to transition to snow in the Boston area Friday morning. This snow could change back to rain midday depending on how heavy the precipitation is. In the valleys of the mountains in New England, temperatures will not be significantly cool so some mixing or even a changeover to rain could be possible.
Snowfall totals will vary by elevation, with 9 to 10 inches possible in the highest of elevations, according to the NWS in Boston. The office is also warning about some possible power outages, considering how wet and heavy the snow is.
Up to 7 inches of snow has already fallen in New Hampshire and Vermont, as of Friday morning, and additional snow is expected. Cooler-than-normal air temperatures are abetting the snow, with temperatures as much as 15 degrees below average on Friday.
That translates to high temperatures only in the 40s and 50s. Temperatures will gradually warm up this weekend in the storm's wake, turning to above average on Sunday and Monday before another cool down returns by mid-next week. Plains snow event ending. Over a foot of snow has been reported in Aspen Park, Colorado, while the Denver metro area has measured totals around inches, as of Friday morning.
Snow will gradually exit the mountainous region Friday and track more toward the central Plains. We either require the cold air to meet a rain-bearing weather front and turn it into snow, or for the cold air to pick up enough moisture from its short journey across the North Sea, to form showers. There are also the effects of air rising up hills and mountains. Often we can see the hilltops covered in snow, but none at ground level. That is because the air at the top is cold enough for snow, but the air at the bottom is too warm and the snow melts to bring sleet or rain.
Check the altitude of your town to see if you would have seen rain or snow on this occasion so if you live above ft above sea level, you would have seen snow on this day, if you live below ft then you would have seen rain.
As it falls to earth, it moves through warmer air most of the time and melts. Depending on the temperature of the air near the ground we either see rain or sleet or hail.
There are several things forecasters look at to predict how low down the precipitation will fall as snow:. Snow forecasting in the UK. What do we need for snow to fall in the UK? What is the freezing level? Why is snow forecasting in the UK difficult?
