Missouri.

.DAY ONE...THIS AFTERNOON AND TONIGHT

Dangerous heat continues this evening with heat index readings
peaking around 100 to 105 degrees. A Heat Advisory remains in
effect until 8 PM.

A line of storms is expected to develop or move into portions of
eastern Iowa and far northwest Illinois, roughly along and northwest
of a line from Washington, Iowa to Freeport, Illinois late this

winds the primary threat. Heavy rainfall and localized flooding is
also possible.

Heat may continue to be at dangerous levels for portions of the

An active pattern will lead to near daily chances for showers
and storms through at least Friday. There may also be a risk for
some severe weather and heavy rainfall at times. Any repeated
rounds of heavy rainfall could lead to a risk for flooding. The
Cedar, Iowa and Wapsipinicon rivers in eastern Iowa are especially
susceptible to flooding due to ongoing high water levels from
recent heavy rain in the headwaters. A river flood watch has been
issued for portions of the Iowa and Cedar rivers. Please see the
latest statement for details.
