Major storm to hit NH with 10 to 20 inches of snow, blizzard conditions Tuesday

NH1 Meteorologist

Tuesday's storm is going to be serious. We've had storms with just as much snow this winter, but this one will hit quickly and hit hard.

Watch

A foot or more of snow will fall in just 12 hours. Whiteouts and blizzard conditions are expected during the height of the storm Tuesday afternoon, making travel extremely dangerous and even impossible at times.

Damaging wind gusts will cause power outages during the height of the storm.

THE TIMELINE

The first flakes will fall near the Massachusetts border between 7 a.m. and 8 a.m. Tuesday.

Snow overspreads the rest of southern and central New Hampshire between 8 a.m. and 10 a.m.

Snow will move into the northern half of the state between 10 a.m. and noon.

Once it begins, the snow will quickly become heavy, with roads becoming snow covered and slippery in a short period of time.

The height of the storm will be from about noon to 7 p.m. During this time, snow will fall at the rate of 1 to 3 inches per hour. "Thundersnow" is likely in spots. Whiteout, near blizzard conditions will make travel extremely dangerous and even impossible at times during the afternoon and early evening.

During the evening, the snow will start to taper and lessen in intensity.

Snow showers will linger into Wednesday morning, but the accumulating snow will end in most places Tuesday night.

IMPACT ON LOCAL ELECTIONS

Tuesday is Election Day for towns across New Hampshire. Some have already postponed voting due to the storm. Check with your town to see if they have made changes as a result of the storm.

STRONG WIND GUSTS

Northeast winds will be damaging during the height of the storm. Usually in these situations, strong wind gusts are limited to the coastline. However, in this case, strong gusts are also possible inland. This means power outages are possible throughout the entire state. Make the necessary preparations just in case you lose power.

The strongest winds will be Tuesday afternoon and Tuesday evening. Northeast wind gusts to 60+ mph are likely near the seacoast, 40+ mph inland. These strong winds will combine with the heavy snow to create blizzard conditions.

SNOW TOTALS

In total, a widespread 10 to 20 inches of snow is expected across New Hampshire.

We have done our best to highlight which areas have the highest chance of receiving the highest amounts.

It's possible a few areas see over 20 inches, near 2 feet.

Totals may range quite a bit from town to town depending on where the heaviest snow bands exactly set up. However, this is a situation where widespread totals over a foot of snow are expected.
