An active afternoon?

August 17, 2010

An attractive picture off the southern Oregon coast this morning. Thunderstorms started popping up around 7 a.m. This is associated with that upper-level low that looks to be pushing eastward. Models have it tracking up over the central Cascades and could impact the central Valley this afternoon. My forecast for today calls for some some thunderstorms late this afternoon and evening in parts of central and eastern Oregon. There are some pretty good CAPE values for this afternoon near Eugene and Salem. I am not anticipating any action there but with that high CAPE, that would be the best spot in the valley where some storms could pop up.

Meanwhile we remain under a heat advisory for the northern and central Willamette valley. One more day of 90+ degree weather before the cool down begins. Who’s ready for it?
