NATIONAL WEATHER SUMMARY:

In the East, a few isolated showers pushed across the eastern Great Lakes, but rainfall was light. To the south, additional isolated showers hung over the east coast of Florida. Most areas received between a tenth to a quarter of an inch. But, some areas received locally higher totals with Vero Beach, Florida recording 1-point-48 inches of rain. Elsewhere, conditions were dry with partly cloudy skies in the Gulf Coast states, Southeast, Carolinas, Mid-Atlantic, the majority of the Great Lakes, the Ohio and Tennessee Valleys, and the Northeast.

In the central third of the country, scattered showers and thunderstorms pushed across the Southern Plains as well as the Lower and Middle Mississippi Valley. Locally heavy rainfall of one to 3-point-5 inches was reported in eastern Texas, Oklahoma, Louisiana, and Arkansas, which led to areas of flash flooding.

Some isolated strong to severe activity did occur with these cells producing wind damage to trees and powerlines outside Richland, Texas. To the north, a few showers moved into northwestern North Dakota. Patchy fog and areas of haze impacted the Upper Mississippi Valley, the Midwest, and the parts of the Central Plains during the morning hours. High pressure and partly cloudy skies were prevalent across portions of the northern Plains.

In the West, scattered showers and thunderstorms spread across the Rocky Mountains, the northern High Plains, the Desert Southwest, and the northern Great Basin. Some severe weather was recorded with this activity. For example, locally heavy rainfall led to flash flooding in southeastern Idaho, one inch hail was recorded in Evanston, Wyoming, and at least one tornado was observed outside Soda Springs, Idaho. Further west, areas of patchy fog were reported in northwestern Washington during the morning hours. Conditions in most of the Pacific Northwest, California, and the southern Great Basin were dry with partly cloudy skies.

ON THIS DATE IN HISTORY:

In 1881, smoke and haze from forest fires in Michigan created a yellow tint to the skies in the Northeast. As many as twenty towns were destroyed and five hundred people perished on what was to later be called "The Yellow Day".

In 1972, Tropical Depression Hyacinth impacted southern California. It was the first depression to hit California since 1939 and caused no deaths.

In 1981, Tropical Depression Norman impacted southern California destroying ninety-five percent of the raisin crop in the state which was being dried out at the time.

FRONTS ACROSS THE NATION

A stationary front is draped across eastern North Carolina, eastern Virginia, Pennsylvania, and northern Michigan.

A cold front is over Minnesota, eastern North Dakota, South Dakota, northwestern Nebraska, and Wyoming.

A cold front is over western Wyoming, Utah, and Nevada.

NATIONAL WEATHER FORECAST

In the East, an upper-level trough will produce mostly cloudy skies with scattered showers and thunderstorms across the Great Lakes region, and western portions of both the Ohio and Tennessee Valleys. No severe weather is expected. Rainfall amounts of a quarter of an inch will be possible. Elsewhere, partly cloudy skies with a chance for isolated thunderstorms can be expected along the Gulf Coast and Florida. No severe weather is expected, and rainfall amounts should remain light. Otherwise, high pressure will allow for fair skies and dry conditions throughout the Northeast, the Mid-Atlantic region, eastern portions of both the Ohio and Tennessee Valleys, and the Southeast. High temperatures will reach into the 70s and 80s across the Northeast and Great Lakes region; and into the upper 80s to the mid 90s through the Ohio and Tennessee Valleys, the Mid-Atlantic region, the Southeast, and Florida.

Across the central part of the country, a strong low pressure system will bring scattered showers and strong to severe thunderstorms to the northern Plains and the Upper Mississippi Valley. Frequent lightning, strong winds, large hail, and heavy downpours will accompany the strongest storms. Rainfall amounts of one to two inches will be possible and may lead to areas of flooding. Elsewhere, partly to mostly cloudy skies with widely scattered showers and thunderstorms can be expected across the central and southern Plains, and the Middle and Lower Mississippi Valley. The main concern with this activity will be periods of heavy rain that may lead to localized areas of flooding. Rainfall amounts of up to an inch will be possible. High temperatures will reach into the upper 70s to the lower 90s.

In the West, partly cloudy skies with afternoon and evening showers and thunderstorms can be expected across the high Plains, the Rocky Mountains, and the Desert Southwest. Rainfall amounts of up to a half of an inch will be possible in a very short amount of time and will likely lead to areas of flash flooding. Otherwise, fair skies and dry conditions will prevail across the Great Basin, California, and the Pacific Northwest. High temperatures will reach into the 60s and 70s across the Pacific Northwest, the northern Rocky Mountains, and the northern high Plains; into the 80s and 90s through the central and southern high Plains, the central and southern Rocky Mountains; the Great Basin, and coastal California; and into the upper 90s to near 110 through interior California and the Desert Southwest.
