quote:Wintry weather marked the first days of autumn across parts of the Intermountain West as snow mixed in with the changing fall foliage.
"A strong storm system barreled into the West this past week and brought a shot of cooler air from Canada which lead to some snow across the higher elevations of the Rockies," said AccuWeather Meteorologist Jordan Root. "Snow reached to elevations as low as 7,000 feet, making it the first snow of the season for some. Laramie, Wyoming measured around 2 inches of snow."
Some locations in Utah reported anywhere from half a foot of snow to a foot of snow.
quote:Frequent storms to bring above-normal snowfall to northeastern US
Frequent storms across the northeastern U.S. this winter may lead to an above-normal season for snowfall.
"I think the Northeast is going to see more than just a few, maybe several, systems in the course of the season," AccuWeather Long-Range Forecaster Paul Pastelok said.
Unlike last season, in which most of winter's snowfall came from a few heavy-hitting storms, this winter will last into the early or middle part of spring and will feature frequent snow events.
According to Pastelok, accumulation may be limited in areas south of New York City, such as Philadelphia, D.C. and Baltimore. These areas will see a handful of changeover systems, where falling snow transitions to rain and sleet.
"But still, Boston, Hartford, along the coastal areas up into Connecticut and southern New England, they can still have a fair amount of snow," he said.
Overall, it's predicted that the region will total a below-normal number of subzero days, though the temperature will average 3-5 degrees Fahrenheit lower than last year.
Damaging freeze may threaten citrus crop in southeastern US
Winter will slowly creep into the Southeast this season, as very mild air hangs on throughout the month of December.
However, the new year will usher in a pattern change as a sudden burst of cold air penetrates the region.
"I am afraid that we have a shot at seeing a damaging freeze in central Florida in mid- to late January this year," Pastelok said.
The chill could spell disaster for the area's citrus farmers.
Cold air will once again retreat following January and the threat is predicted to shift to severe weather.
"Places like Atlanta, Chattanooga, even up into Roanoke, they could have some severe weather," Pastelok said. "But if the storm track is a little farther east, then you're looking more like Tallahassee to Savannah and, maybe, Charleston."

Bitter cold to grip the northern Plains, Midwest
Old man winter won't hold back in the northern Plains this season with shots of brutally cold air predicted to slice through the region.
Developing snowpack in early December may contribute to even colder weather. Temperatures will plummet as the season goes on, averaging 6 to 9 degrees lower overall than last winter.
"...There are going to be some nights, especially if there's snowcover in the heart of winter, that could get down to 20 or 30 below, especially in parts of Minnesota like International Falls and Duluth and parts of the Dakotas," Pastelok said.
Cold air will also remain entrenched across the Midwest after arriving in late November. Coupled with warmer waters over the Great Lakes, an early start to lake-effect season is in store.
"I do feel we're going to kick this season off pretty quick, especially the western lakes. But I think even the eastern lakes will get involved and it will extend all the way out to January," he said.
Winter to get late start across southern Plains, Gulf Coast
Fall-like weather will linger into the winter season across the southern Plains and Gulf Coast, but a change will loom on the horizon.
"A turnaround could come into late December and January as chillier air masses work down from the north," Pastelok said.
Though the milder weather will retreat, dryness will stick around, becoming a major theme of the season.
"The area of the country that may miss out on big [snow] storms this year may be Dallas and Little Rock," he said. However, a few disruptive ice events are not out of the question.
Northern California towns in danger of running out of water for 3rd year in a row
Early storms to blast Northwest, northern California
Winter will waste no time in the northwestern U.S. and northern California, as the season kicks off with rain and winter storms.
"They're going to start out pretty wet, especially from northern California into the Northwest coast," Pastelok said. "I think that, right off the bat in December, we start to see the snow piling up in the mountains."
November and December will see the most action, before high pressure builds in and stormy weather eases back in late January and February.
Dry, warm season in store for Southern California, Southwest
While moisture aims for the Northwest, warm and dry conditions will span much of the season for central and Southern California and the Southwest.
"December is [looking] very warm [in the Southwest] and I think we could break some record high temperatures," Pastelok said.
A few cold shots will hit areas like Phoenix and Flagstaff, Arizona, in January, but the warm weather will quickly rebound.
For Southern California, the pattern will exacerbate ongoing drought conditions.
"We're in a pattern that doesn't really show a lot of rain coming toward Southern California, so I don't expect too much relief," Pastelok said.
What precipitation does fall in California will aim primarily for the north, though it will fail to have the significance of last January when the region was hammered by heavy rain and snow.
"I do think in the early part of the season we're looking good anywhere from San Francisco, Sacramento and into the mountains," he said.
"...If we can get some snowpack built up in the north, we can fill up these reservoirs going into spring and summer."
quote:Following a damp weekend and early week in the northwestern U.S., the region will receive its first significant snowfall of the season beginning on Wednesday.
The precipitation will not fall as snow everywhere, however.
Rain can be expected throughout much of Washington, Oregon and California on Wednesday. Scattered showers may make an appearance as far south as Los Angeles.
What sets this storm apart from those earlier in the week will be the layer of chilly air that will accompany the precipitation farther inland.
"The push of much-colder air will change rain to snow across the Cascades and Sierra Nevada down to pass levels by Wednesday with accumulations likely," AccuWeather Meteorologist Brett Rathbun said.
Motorists should drive cautiously in snowy conditions, particularly in areas of heavy snow where visibility may be limited at pass levels.
On Wednesday, snow and sleet will fall along with the rain over Idaho, northern Nevada and western Montana. These areas will be cold enough to have a complete transition to snow for Thursday.

The impending cold shot threatens to be the most far-reaching and bone-chilling blast so far this season.
“After the first true cold shot of the year this past week, much of the northern Plains can expect a more formidable shot of arctic air again this upcoming week,” AccuWeather Meteorologist Max Vido said.
The cold will be severe enough to bring the risk of frostbite or hypothermia to those spending time outdoors without proper clothing.
Temperatures from the northern and central Plains to much of the Midwest are likely to be 5 to 20 degrees Fahrenheit lower, on average, when compared to levels from last week.

Widespread freezing rain produced by Winter Storm "Jupiter" persists for much of western Oklahoma, Kansas, northern Missouri, and western Iowa. Continuing snow is forecast to the north of the freezing rain, and to the south, heavy rain and the potential for severe thunderstorms. As of late Sunday, January 15, 2017, the death toll has risen to 6. Tens of thousands have already lost power and there is a potential millions could be affected by power outages.
A significant winter storm system hit much of the central US this weekend and will continue through Monday, January 17, the National Weather Service said. More than 30 million Americans are under some type of wintry watch, and 10 million of those are under an ice storm warning.
The hardest-hit states are Oklahoma, Kansas and Missouri with up to 2.5 cm (1 inch) of ice coating trees, power lines and roads. There is a potential millions of residents will lose power.
The weather service also issued a tornado watch for large parts of Texas and a tornado warning for just west of Waco. At least one tornado has touched down in central Texas, the service confirmed. Their spokesman said damage was reported Sunday evening in the Bosque County town of Clifton, about 100 km (62 miles) southwest of Forth Worth, and east of Lake Whitney, but it's unclear if both areas were hit by the same tornado. No injuries have been reported.
As of late Sunday, January 15, Jupiter was blamed for the deaths of at least six people. Two deaths occurred in separate accidents in Kansas, three in Missouri and one in Oklahoma. All of them died on roads.

By JEREMY WHITE and HENRY FOUNTAIN MARCH 8, 2017
After a mild winter across much of the United States, February brought abnormally high temperatures, especially east of the Rockies. Spring weather arrived more than three weeks earlier than usual in some places, and new research released Wednesday shows a strong link to climate change.

De noordoostkust van de Verenigde Staten maakt zich op voor een zeer zware sneeuwstorm. Amerikaanse weerdiensten hebben gewaarschuwd dat het de zwaarste winterstorm in zeker tientallen jaren wordt.
Grote steden als New York, Boston en Philadelphia maken zich op voor zware sneeuwval en hevige windvlagen, aldus Amerikaanse media.
De sneeuwval gaat vermoedelijk voor zorgen dat grote wegen moeilijk begaanbaar worden. Het zwaartepunt van de storm wordt dinsdag verwacht, als zware windstoten de uitval van elektriciteitsvoorzieningen in grote stedelijke gebieden kan gaan veroorzaken.
Ook waarschuwen autoriteiten voor omvallende bomen langs wegen.

De National Weather Service heeft een stormwaarschuwing afgegeven voor New York en delen van de staten New Jersey en Connecticut. Een mildere waarschuwing is afgegeven voor de hele oostkust van de VS.
Volgens meteorologen zou het een van de tien zwaarste sneeuwstormen aan de oostkust van de afgelopen eeuw kunnen worden. Weerplaza verwacht dat zeker 50 centimeter sneeuw gaat vallen in New York.
quote:A classic late-season nor’easter has all the ingredients to produce what could be near-record-heavy March snow and dangerously strong winds in coastal cities from Washington, D.C., to Boston. But if the devil were ever in the details, it’s right now. The dividing line between rain and snow in this storm, dubbed Stella by The Weather Channel, will be close enough to the Interstate 95 corridor to keep forecasters sweating. Right now it appears that the meteorological bounty will be mainly in the form of snow for the big East Coast cities. However, just a minor shift in track could bring rain or sleet into the metropolitan areas, at least for a brief period.
There’s no doubt that a big storm is in the cards. Upper-level energy from two sources—a large trough swinging across the Midwest and a upper-level wave at the base of this trough over the Southern Plains—will be joining forces along the East Coast by Tuesday. The interplay between these two factors is just one of the elements of uncertainty on the table.
What’s clear is that a surface low off the central Gulf Coast on Monday morning will begin to strengthen near the Outer Banks Monday night, then rapidly intensify as it moves northeast along and/or just off the East Coast through the day on Tuesday. As shown in Figure 1 below, the 12Z Monday run of the GFS model deepens the low 23 millibars in 24 hours, from 2:00 am EDT Tuesday to 2:00 am Wednesday, as it moves from near Cape Hatteras, NC (1000 mb), to the central coast of Maine (977 mb). This would bring the low very close to the official definition of a meteorological “bomb”—a midlatitude low that deepens at least 24 millibars in 24 hours.
