The Nation's Weather National Weather Summary
for Monday July 13, 2009

NATIONAL WEATHER SUMMARY:

In the East, pleasant weather returned to the northeastern
states behind a cold front with partly cloudy skies and comfortable
mid-summer temperatures. The back end of the front trailed south
from Virginia and northern North Carolina to the Tennessee Valley.
Strong to severe thunderstorms erupted during the afternoon hours
across southeast Virginia where there were several reports of wind
damage from estimated 60-70 mph winds. Early morning storms
dissipated across eastern Tennessee but numerous thunderstorms
affected most of central and eastern Tennessee and northern Georgia
again during the afternoon and evening hours. A lot of this
activity was severe from south central Kentucky through central
Tennessee with a lot of felled trees reported. Scattered
thunderstorm clusters were also common across southern Mississippi,
Alabama and the Florida peninsula through the afternoon hours.
Across the central states, Canadian high pressure brought dry conditions and cool temperatures to the Great Lakes region. A new record low was established at International Falls, Minnesota at 35 and two additional record lows were tied in Wisconsin. Across the South it was a very different story with very hot weather
continuing. Temperatures soared to over 100 again in most areas
from southern Kansas through Texas with upper 90s over much of
Arkansas and Louisiana. In between these two air masses, storms
continued from the high Central Plains through the mid Mississippi
Valley. One complex of storms moved from eastern Kansas through
Missouri and southern Illinois with another area of storms
advancing south from southeast South Dakota through eastern
Nebraska and western Iowa.
In the West, thunderstorms developed along the Front Range from Colorado to southern Wyoming late in the day bringing hail to a lot of the area. Hail was reported to be as big as golf balls in some
areas and in Douglas, Wyo., the ground was completely white after
hail fell for 30 minutes. Scattered thunderstorms were common
throughout the northwest states with a few severe reports during
the afternoon from eastern areas of Washington and Oregon to
western Montana. It was mainly dry over the southwest with very hot
temperatures continuing over the Deserts. Phoenix tied a record
high for the day at 115.

Iowa.
