Winter Storm Orion Forecast: Light Snow in the Midwest, Northeast

Published: February 9, 2014

Winter Storm Orion will bring some light snow to parts of the Midwest and Northeast through Monday morning. Meanwhile, snow will continue across the mountains of the West, but that activity is no longer connected to the atmospheric disturbance that prompted the naming of Winter Storm Orion.

The first in a series of disturbances moved into the Northwest on Thursday. Another disturbance followed closely on its heels Friday into early Saturday, spreading more wintry weather into the Willamette Valley of Oregon as well as the interior of southeast Washington and northeast Oregon.

With cold air in place, snow fell in the lower elevations of Oregon and southern Washington from Portland, Ore. and Vancouver, Wash. to Eugene, Ore., Pullman, Wash. and Pendleton, Ore.

A two-day total of 5.5 inches of snow was measured in downtown Portland. Of that total, 3.8 inches fell Thursday, making it the fifth greatest single-day snowfall total in the city dating back to 1940, and the city's snowiest February in 21 years.

Up to 18 inches of snow was reported in Bend, up to 16 inches was measured in CorvallisEugene tallied 8.7 inches, and The Dalles picked up 10 inches.

While Winter Storm Orion has moved on into the Midwest and Northeast, there is still a steady stream of moist Pacific air moving in and interacting with cold air near ground level. As a result, some light freezing rain has fallen Sunday in parts of northwest Oregon around Portland.

Meanwhile, scattered mountain snows will continue in this regime from the Sierra Nevada to the Rockies. Notably, snow will fall as low as 6,500 feet Sunday over the Sierra, bringing snow to Donner Summit and a section of Interstate 80. In addition, heavy snow will affect Interstate 70 in Colorado around Vail and the Eisenhower Tunnel area west of Denver, causing major delays in combination with ski traffic Sunday.

Avalanche warnings have been posted for parts of the Sierra Nevada as well as the mountains of central and southeast Idaho, western Wyoming, western Colorado, and central and northern Utah. This mainly applies to backcountry areas.

Fortunately, Orion and the ensuing moist pattern have also brought welcome rainfall to California.

Weather Underground historian Christopher C. Burt told that over 14 inches of rain fell on Mount Tamalpais in Marin County, with 8 inches of that in just 12 hours Friday night and Saturday morning. Over 5 inches of rain fell in the lower elevations of Marin County, with 1 to 2 inches of rain common south of the Golden Gate in places such as San Francisco and Oakland, Burt said.

The rain comes on the heels of a nearly rainless January for much of the Golden State.

The original disturbance that brought the severe winter weather to the Northwest late last week is now spreading light snow through the Midwest and Northeast.

The light snow will continue in parts of the Ohio Valley through the very early morning hours of Monday, but should be nearly gone by sunrise. Only minor accumulations are expected.

By the wee hours of Monday morning most of the snow will be confined to New England. The last of the light snow showers should wind down by late Monday, in Maine.

Total accumulations will generally be 3 inches or less from this fast-moving final phase of Winter Storm Orion.

This freshly-fallen snow may lead to some slippery roads Monday morning in New England and the interior Northeast, possibly including parts of the New York City metro area. However, we expect the snow to have largely ended by the Monday morning commute.

A strong tropical wave with plenty of spin and heavy thunderstorm activity (Invest 91L) moved off the coast of Africa on Thursday, and is headed west at 15 - 20 mph, on a path that will take it a few hundred miles south of the Cape Verde islands over the weekend. The GFS model showed development of 91L into a tropical depression by Tuesday midway between Africa and the Lesser Antilles Islands.

UPDATE: Crazy Summer in Hawaii: Record Rainfall, Record Heat, and Snow!

Although much media attention weather-wise (at least recently) for Hawaii has been about tropical storms an even more interesting story has been the record wet August in Honolulu and Lihue and the hottest summer and hottest single month (August) on record for many Hawaiian cities. Despite a record warm July, accumulating snow managed to dust the summit of Mauna Kea on the Big Island. Here are some details about the above events.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
