NATIONAL WEATHER SUMMARY:

In the East, a deep upper-level trough continued to push across the Ohio and Tennessee Valleys and into the Eastern Seaboard throughout the day. Scattered heavy rain showers plowed through the majority of the Ohio River Valley and the eastern Tennessee Valley late this afternoon, dumping upward of two additional inches of rain in these areas. Showers and isolated thunderstorms extended as far south as the central Gulf Coast, and north across much of the Northeast. Rainfall totals in these areas however, were generally under a half-inch. Continued heavy rain showers caused river flooding problems, as well as localized flash flooding from West Virginia east into Indiana, and south into Tennessee. Meanwhile, clouds have increased along the immediate southeastern coastline, but it remained dry throughout the evening from coastal North Carolina to Florida.

For the western two-thirds of the country, the vast majority of the Plains and all of the western states featured partly cloudy to clear skies and dry conditions as high pressure prevailed. However, a few lingering showers impacted areas from southern Missouri down into Arkansas as an upper-level low remained nearly stationary in the vicinity. Rainfall amounts have mainly remained under a quarter-inch across this region. Farther west, strong Santa Ana winds coupled with above seasonal normal temperatures, continued to nourish fires across the southern portion of the state. Winds gusting from 25 to 40 miles per hour inhibited fire-fighting efforts spanning from Los Angeles to the California-Mexico border.

ON THIS DATE IN HISTORY:

In 1989, an early-season winter storm struck the Pacific Northwest and the Sierra Nevadas; 21 inches of snow fell at Donner Summit, California, with nearly three feet reported near Lake Tahoe.

In 1992, three tornadoes touched down across the Flagstaff, Arizona area. Two-hundred-sixty acres of Ponderosa Pine was destroyed as a twister ripped through the Crater National Monument.

In 1975, a reported 33 inches of snow fell during a two-day time-span near the Mesa Lake, California reservoir.

FRONTS ACROSS THE NATION:

A cold front extends over Maine, New Hampshire, Vermont, New York, Pennsylvania, western Maryland, eastern West Virginia, western Virginia, eastern Tennessee, far-western North Carolina, far-western South Carolina, Georgia, and the eastern Florida Panhandle.

A cold front sits over the upper Peninsula of Michigan, Wisconsin, northern Iowa, South Dakota, North Dakota, and northeastern Montana.

NATIONAL WEATHER FORECAST:

Today across the East, a cold front and low pressure system will bring scattered showers and embedded thunderstorms to the Northeast, the Mid-Atlantic and parts of the Ohio Valley, the Southeast, and the Tennessee Valley. Common rainfall totals will be tenth to a half of an-inch for most areas; but, local embedded strong thunderstorms could make rainfall totals up to an inch possible. An isolated to spotty shower may be possible in the Great Lakes; but, partly cloudy conditions should prevail through most of the day. Highs will be in the 40s and 50s in the Great Lakes; the 50s and 60s in the Northeast, the Tennessee Valley, and the Ohio Valley; and the 60s, 70s, and 80s in the Mid-Atlantic and the Southeast.

Across the western two-thirds of the nation, isolated showers will be possible in the lower Mississippi Valley due to a low pressure system hovering overhead. Rainfall totals are estimated to be around a tenth of an-inch. Rainfall totals up to a quarter of an-inch may be possible across the coastline of the Pacific Northwest due to a mild upper level disturbance. Santa Ana winds in southern California are expected to lighten. Otherwise expect high pressure, clear skies, and dry conditions through the middle and upper Mississippi Valley, the Great Plains, the Rocky Mountains, the Great Basin, the Desert Southwest, and California. Today's highs will reach into the 50s and 60s in the Mississippi Valley and the Pacific Northwest; the 60s and 70s in the northern and central Plains, the Rocky Mountains, and the Great Basin; and the 70s and 80s in the southern Plains, the Desert Southwest, and California.
