Subject: Excessive Heat Expected over Central and Eastern
United States from July 15 through July 22, 2011
A combination of very hot temperatures and high humidity
will create dangerous heat indices over the central United
States this weekend which will spread into the East next
week.
A stagnant weather pattern is developing over the Midwest
as a large region of high pressure develops in the upper
levels of the atmosphere. This pattern will result in
generally light winds and widespread afternoon temperatures
into the upper 90s to lower 100s. This pattern combined
with increasing humidity will create dangerous heat indices
well above 100 degrees over a large portion of the nation
for several days.
Excessive heat watches, warnings and heat advisories are in
effect for a large portion of the central Unites States.
Temperatures will feel like 100 to 110 degrees during the
afternoon hours. For a detailed graphical depiction of the
latest watches, warnings and advisories, see

warnings and advisories can be found at:
