Valid 160100Z - 161200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS
SOUTHEAST OKLAHOMA...FAR WESTERN ARKANSAS...AND FAR NORTH TEXAS...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
THE SOUTHERN PLAINS INTO THE LOWER MISSISSIPPI VALLEY AND ACROSS
PORTIONS OF THE INTERIOR PACIFIC NORTHWEST...
...SUMMARY...
Scattered to numerous severe storms with swaths of wind damage, very
large hail, and a couple brief tornadoes remain possible through
late evening across southeast Oklahoma into western Arkansas and
north/northeast Texas. More isolated strong to severe storms remain
possible this evening across the interior Pacific Northwest.
...Southeast Oklahoma into northeast Texas...
A cluster of supercells have started to congeal across southern
Oklahoma. These supercells have a history of producing very large
hail, but may be transitioning into a greater severe wind threat as
they move into north Texas this evening. These storms may persist
into the overnight hours as the airmass ahead of them remains very
unstable and moderately sheared per 00Z KFWD RAOB. Please see MCD
778 for additional details.
...Ohio Valley...
A few strong to marginally severe storms may persist through the
overnight hours across the Ohio Valley ahead of a cold front.
...Lower Mississippi Valley...
A line of storms will continue southeast across Mississippi this
evening. These storms will have the potential to be severe for
another hour or two before the threat wanes by the late evening as
inhibition increases and storms outrun the better deep-layer shear.
