This hazardous weather outlook is for portions of northern...
western...central...and southern Oklahoma...and western north
Texas.

.DAY ONE...Today and Tonight...

.Thunderstorms...
Scattered thunderstorms will occur today, with most of the activity
developing from southwest and south-central Oklahoma up through central
and northeast parts of Oklahoma. No severe storms are expected,
but heavy rain associated with storms will increase the threat of
flooding.

.Heavy Rain...
Given recent rainfall from southwest into central Oklahoma, it
will not take much additional rain to result in flooding problems.
Although brief in nature, heavy rain associated with thunderstorms
could lead to flash flooding.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday...

.Thunderstorms...
Thunderstorm chances continue through Sunday but decrease somewhat
after Friday.

.Heavy Rain...
Because of saturated ground across much of the area, a risk for
flooding will continue through much of the week.
