The Nation's Weather: Monday, June 22, 2009
NATIONAL WEATHER SUMMARY:
It remained a soggy and unsettled day across the Mid-Atlantic, Northeast and New England. Low pressure continued to churn
offshore, producing widely scattered shower activity across the
region. Rainfall did add up in spots, averaging 0.25-0.50 inch
across a good portion of New Jersey, New York, and interior New
England. Winds also did peak with gusts into the upper 20 mph range
across coastal Massachusetts. Meanwhile, a frontal boundary draped
from the Mid-Mississippi Valley in the eastern Dixie has been the
focus for isolated showers and thunderstorms throughout the day. A
few complexes have produced 1-2 inch hail reports across
southeastern Illinois and downed trees across eastern Tennessee
into South Carolina. In contrast to the near/below normal
temperatures seen in the Northeast, the Deep South and Gulf Coast
saw afternoon temperatures soar into the upper 90s to low 100s.
In the Upper Midwest and Central Plains, showers and
thunderstorms remained the norm as a frontal boundary surges to the
north. Locally heavy rainfall was seen across areas hit with
thunderstorms. In addition, some storms reach strong to severe
strength, producing numerous tornado reports across Iowa and far
southern Minnesota. Most reports were of brief touchdowns and
mainly tornadoes of the weaker variety. Some of the thunderstorms
also packed damaging wind gusts to 60 mph in Iowa in addition to
1-2 inch hail.
In the West, showers and thunderstorms fired up across the Great Basin, Rockies and Intermountain West. A tornado was spotted in Riddle, ID as well as golf ball size hail in southeastern Idaho.
The highest wind gusts of the afternoon were seen in Idaho, with a
74 mph gust reported in Blackfoot, ID. Rainfall amounts of
0.25-0.50 inch were seen in many places of northeastern Nevada,
eastern Oregon, northern Utah, Idaho, Montana and western Wyoming.

ON THIS DATE IN HISTORY:
In 1947 - Twelve inches of rain fell in forty-two minutes at
Holt, MO establishing a world rainfall record. That record was then
tied on January 24-25, 1956, at the Kilauea Sugar Plantation in
Hawaii, as their state record was established with 38 inches of
rain in 24 hours.
In 1987 - Thunderstorms in southern Texas produced wind gusts to 116 mph near Quemado. Thunderstorms in New York State produced 5.01 inches of rain in 24 hours at Buffalo, an all-time record for that location and produced an inch of rain at Bath, PA. The temperatures at Fairbanks, AK soared to 92 degrees, establishing a record for the date.
In 1972 - Hurricane Agnes deluged Pennsylvania and New York State with torrential rains, resulting in the most costly flood in
U.S. history. In the Middle Susquehanna Valley of Pennsylvania, 24
hour rainfall amounts were generally 8-12 inches, with up to 19
inches in extreme southwestern Schuylkill County. At Wilkes-Barre,
PA, the dike was breached destroying much of the town. Flooding
resulted in 117 deaths and 3.1 billion dollars damage.
