NATIONAL WEATHER SUMMARY:

In the East, heavy rain showers and thunderstorms rumbled throughout the early morning hours over northern Lower Michigan and Upper Michigan. Hail up to three-quarters inch in diameter was reported at Calumet, Michigan. Otherwise, locally heavy rainfall was reported over parts of Michigan. Hancock, Michigan reported 3-point-54 inches of rain this morning, with lesser amounts below an inch reported elsewhere across the state. Further eastward, locally dense fog greeted the sunshine over the Appalachians this morning before burning off late. Meanwhile, dry conditions dominated the remainder of the East under a broad dome of high pressure.

In the central states, a large plume of rain kept most of interior Texas and parts of southern Oklahoma wet throughout the day. Del Rio, Texas, was the hardest-hit location in the region, as 3-point-02 inches of rain fell on the city. Other locations in and around Texas reported anywhere from a half-inch to an inch. Flooding was the main concern with most activity roads around Bracketville, Texas being closed due to high running and standing water. Less than a tenth of an inch of rain was reported over most of Oklahoma, though a few locations saw over a quarter of an inch.

Dry conditions and clear skies were reported over the remainder of the Plains states and most of the Midwest during the morning. Leftover showers and thunderstorms were reported over northern Minnesota and northern Wisconsin also; but, rainfall amounts were light.

In the West, scattered rain showers and thunderstorms were observed over the northern Intermoutain West, the northern Rockies, and the Pacific Northwest. In areas such as outside Torrey, Utah significant rainfall led to flash flooding and subsequent road closures. Moderate to locally heavy rainfall amounts were recorded across the Pacific Northwest with most areas recording anywhere between a tenth to a half of an inch. Some areas did experience locally higher totals with 1-point-1 inches of rain recorded at Seattle, Washington. Otherwise, dry conditions and clear skies dominated the High Plains, the Southwest, the remainder of the Rockies, and most of the Great Basin.

In 1950, 38-point-7 inches of rain fell on Yankeetown, Florida in a twenty-four hour period after hurricane Easy hits shore as a category 3 hurricane. Top recorded winds with the system hit 125 miles-per-hour.

In 1996, Hurricane Fran hit North Carolina. river flooding was common with this storm and power was knocked out for over a million people for more than a week. Thirty-four people dies and damage totals were over five billion dollars making it the third most costly hurricane ever.

NATIONAL WEATHER FORECAST

In the East, expect scattered showers and thunderstorms to impact Florida. Some storms could become strong in nature including gusty winds, brief heavy downpours, and frequent lightning. Rainfall totals are expected to be around a tenth to a quarter of an inch. The remainder of the Southeast can look forward to a dry and partly cloudy forecast as high pressure sits over the region. The Mid-Atlantic states may experience a few brief isolated showers due to a weak frontal boundary over the region but most areas are expected to remain dry. Meanwhile the Northeast, Ohio Valley, and Great Lakes can expect partly cloudy to clear skies and dry conditions due to high pressure. Highs will be in the 60s and 70s in the Northeast; the 70s and 80s in the Great Lakes; and the 80s and 90s in the Mid-Atlantic, Ohio Valley, Tennessee Valley, and Southeast.

Across the central part of the country, showers and thunderstorms will impact the southern Plains and Lower and Middle Mississippi Valley with some storms becoming strong to potentially severe. Impacts are expected to include sizable hail, heavy downpours, gusty winds, frequent lightning, and flash flooding. Rainfall totals are estimated to be around a quarter to a half of an inch with locally higher totals above an inch possible. The northern Plains and Upper Mississippi Valley may also experience a few isolated showers and thunderstorms due to a frontal passage. Rainfall should be light with this system. Meanwhile, the central Plains will be partly cloudy and dry. Highs today will be in the 80s and 90s across the region.

In the West, a low pressure system working its way across the Pacific Northwest to the northern Rocky Mountains will bring showers and strong to severe thunderstorms to these regions. These storms could include, brief heavy downpours, large hail, gusty winds above 55 miles-per-hour, frequent lightning, and an isolated tornado or two. Rainfall totals will be between a tenth to a quarter of an inch with local areas above a half inch being likely. Monsoonal moisture is also expected to produce scattered to isolated activity in the central and southern Rocky Mountains and the Desert Southwest; however, brief heavy downpours, gusty winds, and flash flooding should be the only impacts over these regions. Elsewhere, California will remain dry due to high pressure and should expect more hot weather. Today's highs will be in the 60s, 70s, and 80s in the Rocky Mountains, The Intermountian West, and the Pacific Northwest; the 70s, 80s, and 90s in California; and the 80s, 90s, and 100s in the Desert Southwest.
