NATIONAL WEATHER SUMMARY:
Across the eastern part of the country, scattered light snows were exiting the New England region. Snow accumulations were generally light through the morning hours, with a few reports of 3 inches in the higher elevations. Snow continued to fall across the northern portions of Michigan, but with winds relaxing conditions were not as severe as they have been over the past day. Snowfall reports from today were generally under 2 fresh inches of snow, with a few reports to 2-point-5 inches of snow on the immediate shorelines. Isolated lake-effect snow was also reported east of Lake Ontario, with generally light accumulations. The Ohio and Tennessee Valley, Northeast, Mid-Atlantic, Southeast and Deep South woke up to dry conditions with a partly cloudy to mostly clear sunrise.
In the central portion of the U.S., scattered snows fell across the Northern Plains and were spreading into the Upper Mississippi Valley and Northern Great Lakes. Snowfall was generally light, with the high end of totals nearing 2 inches. Scattered freezing rain and sleet was reported across the Southern Plains and Ozarks, with lightning mixing in through the morning hours. Ice accretions were reported across portions of the region, but no major impacts were reported as of yet. Isolated showers mixed in with morning low clouds and fog in southern Texas. Bitter cold gripped the northern portions of Minnesota, with temperatures dipping down to 30 degrees below zero through the morning hours. The Central Plains, Middle Mississippi Valley, Mississippi Delta and northern Texas woke up to partly to mostly cloudy skies and dry conditions.
In the West, a generally quiet morning was set up across the region.
Isolated snows fell across the northern High Plains, with light accumulations in Montana through the morning hours. Another set of isolated snows fell in western Montana with good upslope flow. The central valley of California, northern coast of California and coastlines of the Pacific Northwest were under low clouds and fog through the morning hours. Some reports of visibilities under one-eighth of a mile across northern California came in. Extremely windy conditions were reported across portions of Wyoming and Colorado, with gusts in excess of 60 miles-per-hour in some areas, and sustained speeds of over 40 miles-per-hour. The Great Basin, Inland Pacific Northwest and Desert Southwest reported partly cloudy to mostly clear conditions through the morning.
ON THIS DATE IN HISTORY:
In 1899, the temperatures dropped to 61 degrees below zero in portions of Montana as a great cold wave swept the nation. Columbus, Ohio set a record low at 20 degrees below, while Pittsburgh, Pennsylvania also set a record low at 20 degrees below zero.
In 1959, Sun Valley, Idaho received 38 inches of snow in 24 hours, setting the state record.
In 1983, a major snowstorm dumped large quantities of snow in the eastern third of the United States. Snow amounts reached 25 inches in Allentown, Pennsylvania, 35 inches the Blue ridge mountains of West Virginia, and 19 inches in Windsor Locks, Connecticut. A ship even sunk off the coast of Virginia/Maryland killing 33. Storm casualties totaled up to 46.
FRONTS ACROSS THE NATION:
A cold front lies across southern Georgia, southern Alabama, southern Mississippi, Louisiana and eastern Texas.
A stationary front is stalled out across central Texas, eastern New Mexico, the far western portion of the Oklahoma Panhandle, extreme eastern Colorado, far western Nebraska, southwestern South Dakota, far northeastern Wyoming and Montana.
NATIONAL WEATHER FORECAST:
In the East, look for lake-effect snow showers to fall across western and north-central New York, but should begin to taper off throughout the day. New snowfall accumulations of 3 to 6 inches are likely. To the east, a departing low pressure system will continue to provide for isolated snowfall in northern New England. Total accumulations today will be around 1 to 2 inches. Farther south, a mix of rain, freezing rain, snow, and sleet will impact the western Ohio and Tennessee Valleys by this afternoon. Ice accretions of up to 0-point-15 will be possible. Elsewhere, high pressure will provide for fair and dry conditions. Temperatures will warm into the 10s, 20s, and low 30s across the Great Lakes, Ohio Valley, and the Northeast. Further south, highs will be in the 20s, 30s, and 40s across the Tennessee Valley and the middle Atlantic. High temperatures will be in the 40s, 50s, 60s, and 70s across the Southeast.
In the central United States, an upper-level trough will be responsible for scattered snow showers across the northern and central Plains, as well as across the upper Mississippi Valley. Snowfall accumulations will run from 2 to 6 inches. Farther south, another disturbance will trigger a wintry mix of rain, freezing rain, snow, and sleet across the middle Mississippi Valley. Ice accretions of up to 0-point-25 inches will be possible. Just to the south, isolated showers and thunderstorms will impact the southern Plains and the lower Mississippi Valley. Rainfall amounts in excess of 1 inch will be possible. High temperatures will be in the 0s and 10s for the northern Plains and upper Mississippi Valley. Temperatures will then range from the 10s to the low 40s across the central Plains and the middle Mississippi Valley. Further south, high temperatures will warm into the 40s, 50s, 60s, and 70s across the southern Plains and the lower Mississippi Valley.
In the West, an upper-level trough will cross into the Plains, but not before producing scattered snow showers across the northern and central High Plains and Rockies. Snowfall amounts of 2 to 4 inches likely. Farther west, look for isolated low elevation rain showers and mountain snow across the Pacific Northwest and the northern Great Basin. Snowfall in the higher elevations will range from 4 to 8 inches, with lesser amounts in the valleys. Rainfall amounts at the coast will be less than 0-point-25 inches. Elsewhere, high pressure will allow for fair skies and tranquil conditions across California, central Great Basin, Desert Southwest, and the southern Rockies. High temperatures will warm into the 20s, 30s, and 40s across the Pacific Northwest, Great Basin, as well as the northern and central Rockies. Further south, highs will be in the 50s, 60s, and 70s across California, the Desert Southwest, and the southern Rockies.
