...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF

OREGON...



...SUMMARY...

Thunderstorm associated with strong wind gusts and hail will be

possible this afternoon and early this evening across parts of

central Oregon.



...Central Oregon...

An upper-level low will remain just offshore from the northern

California coast today. To the east of the system, a diffluent

upper-level pattern will be present from the Intermountain West into

the Pacific Northwest. As surface heating takes place across the

Pacific Northwest today, a pocket of weak instability will develop

across Oregon, where MLCAPE is forecast to peak in the 500 to 1000

J/kg range. To the northeast of the upper-level low, large-scale

ascent will aid scattered thunderstorm development. The instability,

along with moderate deep-layer shear and steep mid-level lapse

rates, will likely support a marginal severe threat. The stronger

rotating cells could be associated with hail and isolated damaging

gusts.
