Weather Underground midday recap for Thursday,August 22,2013.
Scattered showers spread across the East on Thursday as two weather
features affected the region. A trough of low pressure in eastern Canada
pushed a cold front over the Great Lakes and across the Midwest. This
system brought heavy rainfall and flooding to southern Wisconsin and
northern Illinois and northern Indiana. Heaviest rainfall was reported
in Peru, Illinois with a midday total of 3.04 inches of rain. Lighter
and more widespread showers developed along the eastern edge of this
cold front as it reached into the far Northeast. This brought scattered
showers to northern New York state and into Maine.
At the same time, rain showers spread across Florida and the Southeast. A
low pressure system spinning over the northeastern Gulf of Mexico
produced disorganized showers and thunderstorms. This system had a low,
30% chance of tropical cyclone development, but continued to spread
abundant moisture northward over Florida and the Southeast. Heavy
rainfall and flooding remained a concern for the region. Heaviest
rainfall was reported at Cross City, Florida with a midday total of 2.13
inches of rain. Warm and humid conditions in between these two systems
allowed for scattered showers and thunderstorms to pop up across most of
the eastern half of the country.
Out West, increased thunderstorm activity over the western states
maintained dangerous fire weather conditions for the Rockies through the
West Coast. In the Northwest, a small yet intense low pressure system
over northern California brought showers and thunderstorms to far
northern California and Oregon.
