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.

10:30am Thursday…

Apparently I was tired and in the wrong place last night!  Parts of the metro area saw a great lightning display and lots of loud thunder.  Others saw lightning in the distance but no thunder.  I had my windows open and heard nothing.  Disappointing…I know.  Gabor Gardonyi caught this shot along the Willamette River

Last night on each of our newscasts I was talking about the weak disturbance moving north across the region during the night and today.  It had put out just a few lightning strikes at that time and I figured we would get at least a little lightning by morning.  But there was lots more than “a little”!  I do remember telling you it might be wet by sunrise, hopefully you weren’t surprised.

Luckily the storms were high enough to be detected by radars in Washington and Pendleton.  Portland’s radar is down for a two week maintenance period.

GOES-17’s Global Lightning Mapper shows where the action was.  First a burst of lightning right over Salem around 2am and then again about 3am over Portland

Then a second round right over North Portland starting at 5am.  That line of strong thunderstorms slowly progressed north over Clark County from around 5-6am.  Looks like that was the best spot to be in for the weather action.  I see some spots from Brush Prairie to Battle Ground to Amboy saw up to 1/2″ of rain…that’s a huge soaker.

Here’s a link to a loop showing all lightning action from 2am-6am over the region:    https://col.st/axcTz

Make sure you hit the LOOP button if it doesn’t start moving.

The big story today otherwise is MUCH COOLER.  We’ll only top out around 80 degrees with a few more showers at times through early afternoon.  By 4pm or so showers should shift north and die out.
