NATIONAL WEATHER SUMMARY:

In the East, scattered showers and thunderstorms pushed across the Ohio Valley, Great Lakes, and into the Appalachians. During the late morning hours, locally heavy rainfall led to flash flood and rising water warnings in western Ohio. A few additional isolated strong showers and thunderstorms developed over parts of the Mid-Atlantic and the Carolinas during mid-day and the afternoon hours with small hail up to an inch in diameter being reported with some storms. Rainfall was light for most cells. Conditions in New England, the Southeast, and the Gulf Coast states were dry with clear to partly cloudy skies.

In the central third of the Nation, scattered showers and thunderstorms extended from western Kansas through the Central Plains, Midwest, and the Upper Mississippi Valley in association with a cold front. Into the early afternoon, severe thunderstorms developed in northwestern Kansas in the central Plains stretching to southern Wisconsin in the Upper Mississippi Valley. Some storms became strong to severe. For example, a 67 mile-per-hour gust was recorded in Tribune, Kansas and a 65 mile-per-hour gust was reported in Oconomowoc, Wisconsin and outside Hartland, Wisconsin. Hail up to 1-point-75 inches in diameter was observed in Anthon, Iowa and outside Palisade, Nebraska. Even a tornado was reported on the east side of Hastings, Nebraska. To the south, a few additional showers and thunderstorms moved into far southern Texas. Conditions in most of the Southern Plains and the Lower Mississippi Valley were dry with partly cloudy skies.

In the West, isolated showers and thunderstorms hung over eastern Colorado and southeastern Montana. Locally heavy rainfall led to flash flood warnings in southeastern Colorado, and isolated severe thunderstorms were reported as well. To the west, a few areas of patchy fog were reported along portions of the California Coast. Conditions in the Rockies, Great Basin, and the Desert Southwest were dry with clear to partly cloudy skies.

ON THIS DATE IN HISTORY:

In 1906, Kansas City, Missouri received six inches of rainfall during the morning hours with three inches in a thirty minute period.

In 1970, dry thunderstorms sparked wildfire in the state of Washington with 100,000 acres burned progressively by the end of the month.

In 1989, Fort Worth, Texas hit 100 degrees for the first time the entire year.

In 1995, Tropical Storm Jerry impacted central Florida. Winds reached forty miles-per-hour sustained with estimates of a foot's worth of rainfall in some areas. Standing water made it so high that catfish temporarily made it onto the runways at West Palm Beach International Airport delaying flights.

FRONTS ACROSS THE NATION

A cold front reaches across North Carolina, western Virginia, eastern West Virginia, and western Pennsylvania.

A stationary front sits over southern Wisconsin, Iowa, and Missouri.

A cold front stretches across Kansas, Colorado, and northern Utah.

NATIONAL WEATHER FORECAST

In the East, scattered showers and thunderstorms are expected to develop over the Great Lakes, Appalachians, Southeast, and along the Gulf Coast. Strong to severe thunderstorms are likely over the Great Lakes, where damaging winds, hail, and a few isolated tornadoes will be possible. Rainfall amounts in excess of an inch will also be possible. Skies over the Northeast, Mid-Atlantic, and Deep South will be partly cloudy and dry. Temperatures will rise into the 60's and 70's in the Northeast; 80's in the Great Lakes and Mid-Atlantic with 90's and 100's in the Southeast, Deep South, and Ohio Valley.

Across the central region, a frontal boundary will spark showers and thunderstorms over the western Great Lakes, Midwest, and central Plains. Strong to severe thunderstorms are likely, and will contain large hail, damaging wind gusts, isolated tornadoes, and heavy rainfall. Isolated thunderstorms are expected over the southern half of Texas. Skies will be fair and dry over the northern Plains, southern Plains, and Lower Mississippi Valley. Temperatures will reach highs in the 70's over the northern and central Plains and Upper Midwest; 80's in the Midwest; with 90's over the central and southern Plains and Texas.

Over the West, high pressure will keep skies over the Pacific Northwest, California, Desert Southwest, and Great Basin partly cloudy with dry conditions. Isolated showers and thunderstorms will develop over the Rockies during the afternoon hours. A few thunderstorms in the central Rockies may become severe, with gusty winds and large hail. Temperatures will rise into the 70's over the northern Rockies and Pacific Northwest; 80's in the Great Basin; 90's in the central and southern Rockies and interior California; with 100's and 110's in the Desert Southwest.
