NATIONAL WEATHER SUMMARY:
In the East, Tropical Depression Gabrielle pushed away from the coastal Mid-Atlantic states, leaving tapering rain showers, mostly cloudy skies and areas of fog over the region overnight and early yesterday morning. Elsewhere, a stalled frontal boundary brought cloudy skies and isolated thunderstorms to the Northeast, while foggy conditions and scattered thunderstorms were observed over the southern Ohio Valley. Scattered thunderstorms were also observed over Florida. Farther north, isolated light rain showers developed over parts of Lower Michigan as a second cold front moved into the area.
In the central states, a potent cold front pushed across the central Plains states and the Upper Midwest, producing widespread rain showers across these areas. Rainfall amounts generally ranged from a tenth of an inch to one inch. 1-point-16 inches of rain was reported at Columbus, Nebraska, yesterday. Farther south, the same stalled frontal boundary that produced fog and rain in the East also produced scattered showers and thunderstorms over the southern Plains and the Lower Mississippi Valley. Some of these storms were slow to move, and heavy amounts of rain were reported in some locales. Oklahoma City, Oklahoma, reported 4-point-90 inches of rain in seven hours overnight. Dallas, Texas, meanwhile, observed 4-point-36 inches of rain today. Elsewhere, dry and cool conditions prevailed over the northern Plains and the Upper Midwest.
In the West, scattered showers and thunderstorms were reported over the central and southern Rockies, as well as the central and southern High Plains, as a couple of disturbances moved out of the area. Rainfall amounts were less than a quarter-inch. The Desert Southwest also experienced a few brief showers and thunderstorms during the midday to afternoon hours with small hail being reported outside Wagon Mound, New Mexico and hail up to an inch and three-quarters reported in Trujillio, New Mexico. Most rainfall totals were between a tenth to a quarter of an inch. Otherwise, generally dry conditions dominated the remainder of the region.
ON THIS DATE IN HISTORY:
In 1954, Hurricane Edna, the second of two Hurricanes passed through New England that year, struck Martha's Vineyard with wind gust up to 120 mile-per-hour being recorded. Twenty-one people were killed and damaged totals forty million dollars.
In 1976, Bullhead City, Arizona is flooded when five inches of rain falls on the area. Roads through the area are closed and damage totaled around three million dollars.
In 1986, Muskegon, Michigan sets a record for twenty-four hour rainfall as six inches fell over the region. Rivers overflowed as many other areas also received high rainfall totals including 7-point-52 inches in Saginaw, Michigan and 4-point-21 inches at Grand Rapids, Michigan.

NATIONAL WEATHER FORECAST
In the East, a strong low pressure system will produce mostly cloudy skies with wide-spread showers and thunderstorms across the Northeast, the Mid-Atlantic region, the Tennessee Valley, the Southeast, and Florida. There will be a chance for a few strong to severe thunderstorms, especially across the Northeast. The strongest storms will be capable of producing frequent lightning, strong winds, sizable hail, and heavy downpours. Rainfall amounts of one inch will be possible. Elsewhere, a second low pressure system will bring mostly cloudy skies and scattered rain showers to the Great Lakes region and parts of the Ohio Valley. Rainfall amounts of around a quarter of an inch will be possible. High temperatures will reach into the 60s and 70s through the Great Lakes region, the Ohio and Tennessee Valleys, and into the Northeast; and into the 80s and the lower 90s across the Mid-Atlantic region, the Southeast, and Florida.
Across the central part of the country, a cold front will continue to produce scattered showers and thunderstorms across much of Texas and into the Lower Mississippi Valley. Areas of flooding or flash flooding will be the main concern with this activity as rainfall amounts of one to two inches will be possible. Otherwise, high pressure will allow for fair skies and cool conditions through the northern and central Plains, and the Upper and Middle Mississippi Valley. High temperatures will reach into the 50s and 60s across the Upper Mississippi Valley; into the 70s to the mid 80s through the majority of the Plains region, the Middle Mississippi Valley, and the northern half of the Lower Mississippi Valley; and into the mid 80s to the mid 90s across the southern half of Texas and into Louisiana.
In the West, partly cloudy skies and the chance for afternoon and evening showers and thunderstorms can be expected across the southern high Plains, the southern Rocky Mountains, and into portions of the Desert Southwest. Localized areas of flash flooding will be the main concern with this activity as rainfall amounts of up to a half of an inch will fall in a very short amount of time. Otherwise, fair skies and dry conditions will prevail throughout the northern and central high Plains, the northern and central Rocky Mountains, the Great Basin, California, and the Pacific Northwest. High temperatures will reach into the 60s and the mid 70s along the coastal regions of both the Pacific Northwest and California; into the upper 70s to the lower 90s through the high Plains, the Rocky Mountains, the Great Basin, and the Pacific Northwest; and into the mid 90s to near 110 across the Desert Southwest and interior California.
