NATIONAL WEATHER SUMMARY

Across the East, high pressure produced partly cloudy to mostly sunny skies and dry conditions over the Southeast, Deep South, Mid-Atlantic, and Ohio Valley. Further to the north, skies were variably cloudy in the Northeast. Snow and rain showers developed during the afternoon over the Great Lakes, while lake effect snowfall continued in Michigan. Gusty winds occurred during the morning in the northern Great Lakes. A gust of 74 miles-per-hour was recorded off the coast of the Keweenaw Peninsula in the Upper Peninsula of Michigan. Other locations reported winds of over 60 miles-per-hour onshore, in Ontonagon, Michigan.

In the central region, snow showers developed and moved over the northern Plains into the Upper Midwest. Accumulations were light. However, the system which produced the snow also brought gusty winds to the region. A gust of 60 miles-per-hour was recorded at Sisseton, South Dakota. Further south, skies were a mix of sun and clouds over the Midwest, and cleared in the central Plains. Widespread sunny skies were reported over the southern Plains and Mississippi Valley.

Over the West, a low pressure system in the northern Rockies produced rain and snow showers over the northern Great Basin, northern Rockies, and Pacific Northwest. Accumulations of over 6 inches were reported in Montana, with locally higher amounts to almost a foot. Gusty winds were also recorded over the area, as shown in the following table:

(Location Wind Speed (miles-per-hour))

Arlington, WY 70

Helena, MT 69

Lincoln, MT 60

Douglas, WY 58

Skies were partly cloudy over the central and southern Rockies, southern Great Basin, Desert Southwest, and California.

ON THIS DATE IN HISTORY

In 1905, strong winds of 60 miles-per-hour lasted for 12 hours in Duluth, Minnesota. A ship went aground 100 offshore in Lake Superior, and the sailors aboard froze to death.

In 1987, a winter storm moved through the Midwest. Ten inches of snow fell in Red Oak, Iowa, while 11 inches was recorded in Shickley, Nebraska. Freezing rain made roads treacherous in the Minneapolis, Minnesota area, while bitter cold moved into the northern Plains. The temperature fell to 18 degrees below zero in Laramie, Wyoming.

In 1989, Santa Ana winds wreaked havoc in southern California. The strong, hot winds set off motion sensitive burglar alarms, and also caused a 30 foot pile of horse manure to spontaneously combust.

FRONTS ACROSS THE NATION

A cold front lingers over southern Florida.

A cold front stretches across Maine, Massachusetts, southern New York, Pennsylvania, Ohio, Indiana, and southern Illinois.

A warm front extends across northern Missouri and into Nebraska.

A cold front lies across western Nebraska, Colorado, Utah, Nevada, and into California.

NATIONAL WEATHER FORECAST

In the eastern two-thirds of the Nation, a strong storm system will develop over the upper Midwest and approach the Great Lakes today with breezy conditions snow showers, accumulating up to an inch or two over the Great Lakes, but as much as 3 to 6 inches over the upper Midwest. Scattered rain showers are expected over Florida. Windy conditions are expected over the northern and central Plains states, with winds out of the north 20 to 30 mph, gusting to 45 miles-per-hour at times. Partly cloudy and tranquil conditions are expected over the southern Plains and the Southeast. Highs will be in the teens and 20s over the northern Plains and upper Midwest, while highs in the 20s to the 40s are expected over the Northeast. 30s and 40s are expected over the Great Lakes, while 40s to the 50s are forecasted over the central Plains, the Ohio Valley, and the Mid-Atlantic states. Highs in the 50s and 60s are expected over the Southeast, the Carolinas, and the Tennessee Valley. Highs in the 60s and 70s are expected over the southern Plains, while 70s and 80s are expected over Florida.

In the West, scattered snow showers are expected over the Northwest, accumulating 2 to 4 inches over the Pacific Northwest, with 1 to 3 inches over the interior Northwest. Windy conditions are expected over the northern High Plains, gusting to 50 miles-per-hour at times. Dry and tranquil conditions are otherwise expected over the Intermountain West, California, and the Desert Southwest. Highs will be in the upper teens and 20s over the Rockies and the northern High Plains, while highs in the 30s and 40s over the Intermountain West, the High Plains, and the Northwest. Highs will be in the 50s to the 70s over California and the Desert Southwest.
