"The oil gets so thick from the cold, and it takes a toll on the machines," he said. "It's not good to keep starting and stopping the machinery all day."
Some of the winter's coldest temperatures - and fiercest wind - roared through the state yesterday, prompting the National Weather Service to issue a wind chill advisory in effect until 7 a.m. today.
But, on another bright note, forecaster Bob Marine of the National Weather Service said there are warmer days ahead. Once this arctic air blows through, he said, the mercury should start climbing toward more seasonable temperatures.
"Once we make it through this spell, it should get much warmer," Marine said. "The forecast from Saturday on looks like it will be in the high 40s or close to 50. This was the coldest air we've had all season though, and it doesn't get much colder."
The arctic air that swept over the area yesterday came right down from the North Pole without a lot of change. That's why the low temperatures and wind chill were so significant, he said, especially in higher altitudes like Mount Washington, which was a frigid 37 degrees below zero.
Marine said the mountain's wind chills dropped the temperature to a staggering 100 degrees below zero, which allowed weather observers at the summit to throw pots of boiling water into the air and watch it turn to snow before their eyes.
But most Southern New Hampshire residents were eager to get their outdoor responsibilities over with and retreat inside.
Shirley Paradise of Derry said the freezing weather was enough to change her daily routine with her dog Buddha.
"I play ball with him every day," Paradise said. "But not today."
She was bundled up in a heavy coat, hat and gloves for her walk around town with Buddha. But even those extra layers weren't enough. She said the wind was burning her face and she couldn't wait to get back home.
That wasn't an option for Londonderry FedEx employee Jerry August, whose face was red from the blustery blast.
"This wind just goes right through you," August said. "This is terrible, you know? You just have to wear layers and move quickly while you're out."
Derry Village School Principal Stephen Miller said the wind blew away any chance of outdoor recess yesterday.
"The children stayed in classrooms for recess, but they have plenty of activities they can do," Miller said. "At the end of the day, it's the walkers we worry about. Sometimes the things they wear are really not winter clothing, especially since spring is around the corner."
It was a day similar to yesterday that convinced U.S. Postal Service employee Shawn Patten that it was time for a change. Patten, a former mail carrier, said he remembers the afternoon he was standing in front of some mailboxes, freezing, and thought, "There has to be something better than this."
There was - Patten is now Salem's postmaster, and he works indoors.
With a high of about 8 degrees and a wind chill around 13 degrees below zero, yesterday's weather forced anyone working outside, walking their dogs or just running errands to throw on extra layers.
The wind caused power problems for some residents, including about 100 Public Service of New Hampshire customers in Milford, who lost power when branches fell on power lines, company spokesman Martin Murray said.
PSNH also temporarily cut power to customers in Hudson and Windham to make repairs to equipment damaged by high wind, Murray said. About 200 people in Hudson were affected, as were several customers near Beaver Brook Road in Windham. Power was cut at about 3:20 p.m. and restored about 15 minutes later.
Fishermen and coastal residents faced an even bigger challenge than those farther inland. The National Weather Service issued a freezing spray warning.
"It's so cold out that as soon as that water makes contact with something metal, it freezes," Marine said. "These warnings are very rare. It's dangerous though because the spray will freeze and then weigh down the boats."
