Friday, July 30th, 12:30 P.M. 

After a warm start to the day, temps will soar close to 100° in the Portland metro area this afternoon/early evening. We are keeping an eye on some clouds and showers over the Cascades this afternoon. I can't rule out the chance for a brief shower or thunderstorm in the metro area or central valley this afternoon and evening.

High pressure will slowly back off over the weekend, but we will still have a southerly wind overhead. Thin smoke and high elevation clouds will be possible at times, and isolated storms could fire up during the afternoons & evenings along the Cascades and east of the mountains. Highs should trend back into mid 90s to upper 80s Saturday and Sunday.

High pressure will continue to inch away from the Pacific Northwest next week, resulting in cooler temperatures. Afternoon highs will slowly trend back down into the 80s, with overnight lows in the upper 50s and low 60s.

Just a few thoughts as we head toward the 10/11pm shows...

Cold air has moved in just as we expected. Everyone at/below freezing in metro area, plus dewpoints keep lowering. That means when precipitation picks up (soon), temperatures drop further.

Roads froze up as expected after sunset. That's a tough one to forecast but things turned out okay there.

Check out the radar at 8:50 (below)...two converging areas of precipitation. Looks like they are meeting over the metro area. It just started dumping on our Timbers Cam. We are still on track for 1-3" snow in metro area by daybreak

Cold air has moved down into the central Willamette Valley = freezing rain and spotty snow for many of you from Woodburn down to Albany. Cold air has slipped onto the northern Oregon and SW Washington coastline. Expect a trace to 2" snow plus patchy freezing rain out there.

Evening model are still VERY snowy with 2nd wave tomorrow evening and night. WRF-GFS still thinks up to a foot total snowfall by Saturday morning. This is the evening run...

That's all, see you on TV at 10/11pm! Chief Meteorologist Mark Nelsen
