NATIONAL WEATHER SUMMARY

In the East, isolated to scattered showers and thunderstorms pushed across portions of the Northeast and eastern Middle Atlantic states this afternoon. The bulk of this activity dissipated shortly after sunset, but skies remained cloudy across the region. To the south, wide-spread showers and strong to severe thunderstorms developed across the Deep South ahead of an approaching frontal boundary. Further west, a powerful upper-level trough and associated surface low, slowly progressed across the Mississippi Valley and into the western Ohio and Tennessee Valleys, triggering scattered strong to severe thunderstorms in its path. Numerous reports of large hail, damaging wind gusts, and isolated tornadoes were reported from the western Great Lakes, along the Mississippi Valley, and east into the western Ohio and Tennessee River Valleys.

In the central third of the Nation, a strong upper-level trough continued to produce scattered showers and thunderstorms across the upper Mississippi Valley and the majority of the Midwest through the evening hours. Many of these thunderstorms became strong to severe late this afternoon, producing large hail, periods of heavy rainfall, winds gusting in excess of 60 miles-per-hour, and isolated tornadoes. To the west, skies cleared across the western half of the northern and central Plains. Winds sustained at 20 to 30 miles-per-hour, with gusts nearing 50 miles-per-hour, were reported from Oklahoma to North Dakota. Elsewhere, fair and dry weather conditions continued across the far southern Plains throughout the day.

In the West, scattered rain showers and mountain snow showers progressed across the Pacific Northwest and northern California, and into portions of the northern Great Basin. Rainfall was generally light, while snowfall accumulations of up to four inches was reported across the higher terrain of the Great Basin and the Cascades. Otherwise, the remainder of the western United States enjoyed dry, tranquil conditions, as high pressure remained the dominate weather feature in the area.

ON THIS DATE IN HISTORY

In 1844, hurricane force winds drove water from Lake Erie into downtown Buffalo, New York; 200 people drowned.

In 1961, an early-season winter storm plowed across the mountains of West Virginia; up to two feet of snow fell near Summersville and Richwood, West Virginia.

In 1984, 25 inches of rain fell across Odem, Texas in a three-hour timespan.

FRONTS ACROSS THE NATION

A warm front sits over far-northern New York, Vermont, New Hampshire, and eastern Massachusetts.

A cold front extends over the Upper Peninsula of Michigan, western Indiana, western Kentucky, western Tennessee, Mississippi, Louisiana, and Texas.

A stationary front sits over southern Idaho and eastern Oregon.

A warm front extends into western Oregon.

NATIONAL WEATHER FORECAST

In the East, a low pressure system and associated cold front will produce showers and thunderstorms in the eastern Great Lakes, the Ohio and Tennessee Valleys, down through the Southeast, and Gulf Coast. Some of this activity may be severe, producing large hail, strong damaging winds, frequent lightning, and heavy rainfall. Showers and thunderstorms will also be possible in the Northeast and Mid-Atlantic states, with some storms possibly becoming strong. Highs will be in the 60's and 70's for the Great Lakes, the Ohio and Tennessee Valleys, the Northeast, and the Mid-Atlantic, while reaching the 80's in the Southeast and the Gulf Coast.

In the Central states, the low pressure system will bring showers with a few embedded thunderstorms to the Upper Midwest. No severe weather is expected with this activity. Elsewhere, expect high pressure to build in behind the cold front, resulting in partly cloudy skies with fair and dry conditions for the Plains, and the Middle and Lower Mississippi Valley. Highs will be in the 40's and 50's in the Upper Midwest and Northern Plains, with 60's and 70's in the Central Plains and Middle Mississippi Valley. Expect highs to reach the 80's, with a few 90's in the Southern Plains and Lower Mississippi Valley.

In the West, a storm system will bring widespread showers to the Pacific Northwest, Northern Rockies, and northern California, into western portions of the Great Basin. Heavy rainfall will be possible for some areas, while snowfall amounts of 4 to 6 inches will be possible for the elevations above 5000 feet. Elsewhere, a broad area of high pressure will result in fair and dry conditions for the rest of the Great Basin and California, as well as the High Plains, Central and Southern Rockies, and the Desert Southwest. Highs will be in the 50's and 60's across the Pacific Northwest, the Rockies, and the Great Basin. Expect highs to soar into the 70's and 80's in the Central and Southern High Plains, as well as southern California and the Desert Southwest.
