The Nation's Weather

Across the East, an upper-level low pushed into the eastern Great Lakes region, producing cloudy skies and wide-spread showers and thunderstorms across the Northeast and the Mid-Atlantic region. Strong to severe thunderstorms affected many locations with frequent lightning, damaging winds, sizable hail, and heavy downpours. Hail two inches in diameter was reported at West Chester, Pennsylvania, and there were many other reports of golf ball size hail. A tornado touched down near Rose Bay, North Carolina in a heavily wooded area, but no damage was reported. Strong winds downed many trees and power lines as well. Heavy rain of 1.73 inches fell at Philadelphia, Pennsylvania and 1.25 inches of rain was reported at Boston, Massachusetts. Elsewhere, scattered afternoon and evening showers and thunderstorms developed across portions of the Southeast and Florida. No severe weather was reported, but Greenville, Mississippi did receive 0.70 inches of rain. Otherwise, fair and dry conditions prevailed through the rest of the region.

Across the western two-thirds of the country, a stationary front produced scattered to numerous showers and thunderstorms across the Lower Mississippi Valley and portions of the southern Plains. No severe weather was reported, but very heavy rainfall produced many areas of flooding and flash flooding. These areas of heavy rain spread from Kansas, eastern Oklahoma, and into Arkansas. Correyville, Kansas reported 4.74 inches of rain, and 4.27 inches fell at Fort Smith, Arkansas. Rainfall amounts of 3.63 inches were received at Bartlesville, Oklahoma, and 2.22 inches fell at Tulsa, Oklahoma. Further west and north, scattered showers and thunderstorms develop during the afternoon and evening hours across the northern Plains, the high Plains, and the Rocky Mountain region. Wide-spread strong to severe thunderstorms developed with this activity. Two funnel clouds were reported near Alzada, Montana, and hail two inches in diameters fell near Beach, ND. Winds gusting to 70 mph also ripped through Whitetail and Raymond, Montana. Rainfall amounts generally ranged from 0.20-0.40 inches. Otherwise, high pressure allowed for fair skies and dry conditions through the Upper and Mid-Mississippi Valley, the Desert Southwest, California, the Great Basin, and the Pacific Northwest.

In 1980, clouds and moisture from Hurricane Allen provided a brief break from the heat across Texas. Highs ranged from the 70s to the lower 90s.

In 1987, an early evening thunderstorm ripped through Alva and Hulett, Wyoming, producing hail two inches in diameter. Snow plows had to be used to clear Highway 24 south of Hulett, Wyoming, where hail formed drifts two feet deep.
