Thunderstorm coverage will continue to increase across parts of
northeast Oklahoma through mid to late morning as early morning
thunderstorms in Kansas continue to spread southeastward. These
storms are not expected to be severe and should diminish by
midday.
Additional isolated to scattered thunderstorm development is
expected across areas to the south and east of Interstate 44 during
the early to mid afternoon hours, near an outflow boundary from
the morning thunderstorms. The strongest thunderstorms may produce
hail to the size of quarters and damaging winds up to 65 mph.
In addition to the thunderstorm threats, high surface moisture
will lead to humid conditions this afternoon. Heat index values
will range from 100 to 105 across much of eastern Oklahoma and
west central Arkansas.
