National Weather Summary for Tuesday, Aug. 11, 2009


Today in the East, a slow moving cold front brought widespread showers and thunderstorms eastward from the Upper Ohio River through much of the Northeast region. Thunderstorms became severe over portions of northeast Ohio and northwest Pennsylvania with strong winds, including a 72 mph gust at Cleveland, Ohio. Hail up to one inch in diameter fell across south central New York and thunderstorms that moved towards the northern New York City suburbs later in the afternoon caused numerous tree damage and scattered power outages. Heat and humidity was felt south of front with highs well into the 90s over much of the Southeast, Carolinas and Mid Atlantic regions. A couple of new record highs were set for the day
including Islip, NY (91) and Washington Dulles near Washington,
D.C. (97).
In the central United States, it was a very stormy day across the Central Plains with numerous severe storms moving west to east across northern and central Kansas. Large hail and winds of 70 mph brought a lot of damage to the area, including a steeple collapse
from a church in Salina, Kansas. Thunderstorms weakened as they
moved into southern Missouri but still produced heavy rain in many
areas. Additional storms developed across northern Oklahoma during
the afternoon hours with many more severe reports. One report near
Okay, Oklahoma of a roof which flew 50 feet off of a home and the
attached metal car port tossed about 200 feet due to high winds.
Additional storms developed during the evening hours across eastern
Colorado with a few dropping hail to 1.50 inches in diameter. Hot
and steamy weather continued across the south with much of Texas
into the 100s for highs once again.
In the West today, it was fairly quiet with high pressure
covering the Rockies. Light rain showers moved into northwest
Washington and gave the Seattle area its first rain in several
days. A few thunderstorms were scattered about New Mexico and
southeast Arizona during the afternoon but the rest of the region
was dry. The intermountain west was still cool with record lows set
at a few sites, including: Alamosa, CO (32); Fort Valley, AZ (33);
Rawlins, WY (37); and Brigham City, UT (46). In contrast, it was
very warm over much of interior and northwest California. The San

In 1987, a severe thunderstorm in Wyoming moved between Alva and Hulett producing hail up to two inches in diameter. Snow plows were used to clear Highway 24 south of Hulett where hail had drifted to two feet deep.
In 1993, a high elevation tornado tore a 17 mile path through the Ashley National Forest in Utah destroying 1000 acres of trees. The tornado reached F3 in strength and damaged was reported as high as 10,800 feet.
