National Weather Summary for Tuesday, August 4, 2009

NATIONAL WEATHER SUMMARY:

Across the eastern portion of the country, yesterday was fairly quiet except for areas of scattered showers and thunderstorms
across the Southeast, Mid Atlantic, and the Tennessee Valley. This
activity was the greatest during the afternoon hours but quickly
diminished during the evening hours. One strong cell dumped 2.55
inches of rain in Savannah, Georgia. Elsewhere, a line of showers
and isolated thunderstorms moved through Michigan early in the day
but diminished by midday. A few showers continued to linger across
Michigan throughout the day ahead of a frontal boundary. Much of
the Northeast, Ohio Valley, and portions of the northern Mid-Atlantic region stayed quiet.
Across the central portion of the country, showers and
thunderstorms were found early in the day from Lake Huron to
central Missouri along a frontal boundary. A few cells in Missouri
along the tail end of this line were capable of producing hail up
to the size of a half-dollar in La Grange, Missouri. Another line
of showers and thunderstorms developed later in the afternoon
yesterday from northern South Dakota to western Minnesota. This
line weakened somewhat across central MN as it shifted south,
eventually separating into two clusters of storms. One cluster
continued over Wisconsin while the other cluster became a larger
complex of storms across Nebraska.
The western half the country had a quiet start to the day. By the afternoon hours, scattered showers and thunderstorms could be found across much of the Rockies from New Mexico and Arizona to
southern Montana, Idaho, and Oregon. This activity diminished by
the evening hours after sunset. Otherwise, dry conditions were
found across the Intermountain West, California, and portions of
the Southwest.
