Portland TV Weathercasters: A Mini-Wiki

August 28, 2016

I’ve spent some time over the past 2 years putting together a listing of all the TV weathercasters we’ve seen in this market over the years.  About a year ago I showed you my work so far.  But just this evening I’ve added a few names, updated a couple of folks that are no longer doing TV weather, and cleaned it up a little in general.

I’ve added the length of the Portland TV career for those that made it to 20 years.  It takes some real stamina, flexibility and likability to make it 20 years in any television weather forecasting job.

A few notes:

  • Jack Capell was the undisputed king, lasting 44 years at KGW!
  • Jim Little was the only one (that I’m aware of) of the “20+ year club” to make it to 3 different stations.  Another 3 years and you’ll join him Rod!
  • I’ve only included those that have/had some sort of regular weather shift, not free-lancers or occasional fill-ins.  There must be another 50 of those spread out over the years.  No insult intended if you are one of those folks.
  • The pre-1980 years get a bit more sketchy, probably quite a few missing names there.
  • Please let me know if you are aware of any errors in these charts.  Either via email or in the comments.

3 Day Heatwave Ends Tonight

August 26, 2016

5pm Friday…

97 in Portland today, what a scorcher, especially for one of the last few days of August.  It was our 4th hottest temperature of the summer:


The numbers around town so far…


And for another day the heat made it to a good chunk of the Oregon Coast.


Quite impressive considering the flow was just barely offshore this time around.  That airflow is now turning to “onshore” which means air begins flowing from the ocean to inland areas.  Yes, that’s what we refer to as “nature’s air conditioning”.  Expect a huge drop in temps tomorrow as a result.  Down a good 10-15 degrees for most of us and a solid 20 degrees at the coastline (in spots that were hot today).

Our 90 degree day count for this season here in Portland is now above average (barely) at 14, of which 9 have been this month.


The 30 year average is 13 days (technically 12.9) at/above 90.  In the end, this summer, June-September, will end up being warmer than normal with about the average number of 90 degrees days, maybe another 1-3 coming in September…we’ll see.

YOUR Phone Can Help Improve OUR Forecasts!

August 23, 2016

Do you use an Android smartphone?  If so, would you consider helping out Pacific Northwest meteorologists by downloading a simple app?


It appears to be a strange request right?  But let me explain:

Cliff Mass (a professor at the University of Washington) has a project in which he’s trying to test the value of pressure observations from smartphones.  Their hypothesis is that a massive number of smartphone pressures could improve the initialization and forecasts of high-resolution numerical prediction models.  They want to use western Oregon/southwest Washington and the downstream regions (Gorge, Eastern Washington/Oregon) as a test area.  But they need to collect smartphone pressures.  To do so they have developed a powerful app for Android smartphones (uWx), which is available on the Google Play Store (https://play.google.com/store/apps/details?id=com.uwx&hl=en).   The web page for the new application is here: https://www.cmetwx.com/.

In addition to collecting pressures, uWx provides wonderful forecasts, full resolution radar, and even accurate elevations for hiking.  So in exchange for providing that information you do get a nice little weather app as well.  Cliff tells me they really need observations from the Portland metro area and Columbia River Gorge.  So please help out if you can.

The app is not available for iOS (Apple) phones for now.

Cliff has done a blog posting about the project as well here:  http://cliffmass.blogspot.com/2016/07/innovative-new-weather-app-observes.html

The Great USA Eclipse Is Just 1 Year Away

August 21, 2016

Sunday 9pm…

We are less than 1 year away from the biggest astronomical event Oregon has seen in over a generation.  There will be a total solar eclipse in our state from 10:15-10:30am on August 21st, 2017.  That means Oregon will be cut in two by a ribbon of total darkness for 2 minutes.  The shadow of the moon will pass along a line from Depot Bay to near Ontario.  It will continue all the way into the SE USA by early afternoon.  This will be the first time since 1979 that we’ll see a total solar eclipse here.  And it’ll be quite awhile until we see another, although it’s interesting that one spot in the SE part of the country will see TWO eclipses within a span of 8 years since there will be one more eclipse back east in 2024.


Assuming skies are clear, the sun will look like this for about 2 minutes along the “line of totality”:


I think this web site is excellent, showing detailed maps of where you want to be for those two minutes:


And here is their map of the path.  Notice how narrow the “zone” will be: Stayton and Madras are perfect, but it’ll be useless to be in the Portland metro area or Bend, they are outside of the path and it will not be totally dark.


A real neat detailed pic from the same website (click for the best view):


Rumor says most or all hotels have been booked up for next year for quite awhile.  I’ve also heard much of remote Olallie Lake Resort is even booked!  There is “no room at the inn” apparently in Madras where thousands (or many tens of thousands or a hundred thousand) will be congregating for the two minute show.  Madras & Mitchell have the sunniest weather, on average, anywhere in the USA for this eclipse.  I’ve even heard a rumor that there could be an extra million or more people congregating on that strip in Oregon that morning.  Sounds like a traffic nightmare maybe?  It is interesting that the two big state parks under the totality with a good chance for sunshine can’t be booked until late November (9 month window).  I wonder how many people will be clicking like crazy on the Detroit Lake and Cove Palisades State Park website reservations on a cold and rainy November morning?

Anyway, read up the eclipse and make your plans!

Record High Temperatures

August 20, 2016

7am Saturday…

What a scorcher yesterday, as expected.  The highlights (thanks to Portland National Weather Service):


Click on these for the full image…

A few notes:

  1.  Friday was the first time we’ve reached 100 in late August (or September) since 1988!  It’s rare to get to 100 this late in the summer season as the sun angle gets lower and nights longer
  2. Astoria just experienced its hottest day in 55 years!  2nd hottest on record at Astoria airport since records began there in 1953.  It hit 100 in 1961 at that location.  Other locations in the Astoria climate record show temps warmer than 98…that was a cause of some self-induced Twitter drama on my part yesterday.
  3. Notice some spots in the north Willamette Valley and Clark County were slightly cooler today?  That was due to the east wind being a little “too strong”.  Slightly cooler air coming in from Eastern OR/WA.  That’s a really tough call in the forecast.  The areas that already had the NE wind Thursday were slightly cooler Friday. Interesting that some models picked up on it.  I think the WRF-GFS and ECMWF had hinted at the possibility.  A very fine nuance to the forecast, but interesting for geeks like me.
  4. 850mb temp over Salem hit +23.4 degrees yesterday afternoon, down just a degree from Thursday afternoon.  Yet some temps warmer in the valley/coast shows what the offshore wind flow can do.  Now image if we would have reached +27 degrees instead!  That’s what happened in mid-August 1977 when PDX hit 105 and some valley locations even warmer.

Here’s an interesting tidbit of hardcore PDX climate info, from Chris Callais over on both weather Facebook groups…yesterday appears to have seen the 2nd warmest noon temp we’ve seen at PDX:



We’ve got one more scorcher today and then Sunday looks wonderful with strong onshore flow.  Troutdale profiler at 6am shows (weaker) offshore flow still going:


It is slightly cooler in the lowest 1,500′.  Hmmm, might just be a 97-99 degree day instead.  That’s quite possible.  We’ll see.  Either way, one more hot day.  Stay cool!

The lengthening nights sure make a difference on our low temperatures this time of year.  I see some 50s in the outlying areas even under this hot airmass.  And PDX made it down into the lower 60s once the wind disappeared.  Yet in a few breezy spots in the hills (West Hills and Eola Hills near Salem) it only got down into the lower 70s.  Feels like Hawaii!

I see low clouds have returned to the coast so it will be MUCH cooler out there.  If you head out there (along with masses of others), it’ll be in the 60s and 70s…very nice.

A 100 Degree Day For Some, More Ahead

August 18, 2016

9:30pm Thursday…

What a scorcher today!  Even without east wind showing up much yet in the western Gorge (at least more than a light breeze) we saw high temperatures poke into the low 100s in parts of the northern Willamette Valley.

Here in Portland we officially made it to 99 at PDX, breaking the record of 96 set just last year on this date…


Check out the 100 Degree Club!


Even Astoria briefly got in on the act…a day early, with an 88 degree high.  That gives you an idea of what is possible tomorrow with a downslope easterly wind out there.  Forks, Washington made it to 96 as the easterlies arrived mid-afternoon.

Tonight rising pressure east of the Cascades means the east wind kicks in through the Gorge and maybe a little over the Cascades as well.  That means we will totally mix down the dry and hot air mass overhead.  I haven’t changed our forecast this evening since everything still appears on track for another record-breaking day tomorrow.  But there are a few minor tweaks…


  • Two more days of record-breaking hot weather ahead.
  • Areas AWAY from the Gorge will likely see another 1-3 degree rise in high temperatures.  That means high temps could be up around 104 degrees in a few spots like Hillsboro, Salem, or Battle Ground.
  • Areas that get the gusty east wind NEAR and IN the Gorge will actually be slightly cooler.  Troutdale likely stays below 100 degrees Friday.
  • The official high temperature forecast at PDX is problematic because too much wind could keep it below 100 again, or if the wind stays light enough it could be 104!  We went in the middle and have a 102 degree forecast.
  • Exact numbers don’t matter because it’s going to be baking hot tomorrow and the heat will begin earlier in the day.  Today it was 81 at noon in Portland. Tomorrow it’ll be 85-90 in those windy locations already at noon.


For the weather geeks out there, the 850mb temperature ended up just as forecast this afternoon over Salem.  It was 24.2 degrees.  The atmosphere overhead will be about the same tomorrow, but offshore flow really kicks in, thus the thoughts above in the highlights.

Looking further ahead, we DO get some quick cooling Sunday with a major marine push.  That should drop us a good 15 degrees, then another 5-10 degrees cooling Monday.  Much better!

That said, it appears there will be one more warmup the 2nd half of NEXT week.  This time temperatures will remain below 95 degrees, hopefully only up around 90.  No rain in sight!
