NATIONAL WEATHER SUMMARY:

In the East, a cold front brought showers and thunderstorms to the Gulf Coast. The largest area of storms dumped heavy amounts of rain over the Florida Peninsula. Among the heaviest amounts:

LOCATION AMOUNT (INCHES)

---------- ---------------

Tampa, Florida 2.93

Orlando, Florida 1.44

St. Petersburg, Florida 1.89

Alexandria, Louisiana 2.77

Lafayette, Louisiana 2.74

A few scattered thunderstorms were reported over the Tennessee Valley, the Mid-Atlantic, and the Southeast, with no severe weather reported. Meanwhile, the Great Lakes, Ohio Valley and the Northeast experienced partly cloudy skies with pleasant evening conditions.

In the Central States, a stalled-out boundary brought ragged areas of scattered showers to the Central and Southern Plains, as well as the Lower Mississippi Valley. These slow-moving storms dumped heavy amounts of rain in some areas. Some of the heaviest amounts included:

LOCATION AMOUNT (INCHES)

----------- -----------------

Hays, Kansas 2.75

Manhattan, Kansas 2.16

Durant, Oklahoma 2.65

Paris, Texas 1.29

Fort Stockton, Texas 1.45

Further north, a broad area of high pressure, along with winds from the south, resulted in dry and pleasant conditions across the Northern Plains, and the Upper and Middle Mississippi Valleys.

In the West, the monsoonal moisture machine produced widespread areas of showers and thunderstorms in the Rockies, Great Basin, and the Desert Southwest. Some locally strong thunderstorms produced high wind gusts and heavy downpours, resulting in flash flooding. Tucson, Arizona reported 2-point-53 inches of rainfall, which flooded downtown streets. Other areas saw rainfall amounts between a half-inch to an inch, with occasional to frequent lightning strikes. Otherwise, partly cloudy skies with dry conditions were observed for the Pacific Northwest, the High Plains, and California.

ON THIS DATE IN HISTORY:

In 1940, a major hurricane affected impacted Georgia and South Carolina.

In 1993, the Great Midwest Flood impacted several states. The flood stage reached 49-point-58 feet in Saint Louis, Missouri.

In 1917, 80 forest fires are ignited in Trinity County, California, when an electrical storm produced several hundred lightning bolts over a small area that was severely dry from a drought.

FRONTS ACROSS THE NATION:

A cold front is moving through Maine and northern Vermont.

A cold front is located over Florida and Mississippi.

A stationary front extends over northern Louisiana, Oklahoma, and northern Texas.

A cold front is located in western North Dakota and Montana.

NATIONAL WEATHER FORECAST:

In the East, partly cloudy skies with the chance for afternoon and evening showers and thunderstorms can be expected across the Southeast and Florida. A few strong thunderstorms will be capable of producing frequent lightning, strong winds, sizable hail, and heavy downpours. Rainfall amounts of up to an inch will be possible. Otherwise, high pressure will provide mostly sunny to partly cloudy skies and dry conditions throughout the Northeast, the Great Lakes region, the Ohio and Tennessee Valleys, and the Mid-Atlantic region. High temperatures will reach into the 80s and 90s.

Across the central part of the country, a low pressure system will produce scattered showers and thunderstorms across the northern Plains and the Upper Mississippi Valley. There will be a chance for strong to severe thunderstorms, capable of producing frequent lightning, strong winds, large hail, isolated tornadoes, and heavy downpours. Rainfall amounts of a half of an inch will be possible. Elsewhere, an upper-level disturbance will produce scattered showers and thunderstorms across the central and southern Plains, and the Lower Mississippi Valley once again. The main concern with this activity will be areas of flooding or flash flooding. Otherwise, fair skies and dry conditions will prevail through the Middle Mississippi Valley. High temperatures will reach into the 80s to near 100.

In the West, expect partly cloudy skies with scattered afternoon and evening showers and thunderstorms across the high Plains, the Rocky Mountains, the Desert Southwest, the Great Basin, and eastern and southern California. A few stronger thunderstorms will be capable of producing dangerous lightning, gusty winds, small hail, and very heavy downpours. Rainfall amounts of up to an inch will be possible in a very short amount of time and will likely lead to areas of flash flooding. Otherwise, mostly sunny to partly cloudy skies and dry conditions will prevail across northern and western California, and the Pacific Northwest. High temperatures will reach into the 60s and 70s along the coastal regions of both the Pacific Northwest and California; and into the upper 80s to the lower 100s through the high Plains, the Rocky Mountains, the Desert Southwest, the Great Basin, interior California, and much of the Pacific Northwest.
