Back from Vacation: Missed a Picture!

August 8, 2011

Cleaning up the Inbox after 17 days off of work (still employed too as far as I know)…found this gem of a pic from Gabor Gardonyi.  Taken two weeks ago near Memaloose State Park.  Nice shot of lightning striking the Columbia River.

And, after those 17 days off, I see nothing has changed weatherwise, a trough still resides along the West Coast with varying amounts of mornings clouds/afternoon sun continuing.

Another Gloomy Morning

August 6, 2011

A solid layer of marine clouds into the western valleys again today, although without all the drizzle the eastern suburbs and foothills saw yesterday.  That kept our temps about 5 degrees below average.  Either way a gloomy start to the weekend today, but we should see a slightly faster “burn-off” (water vapor doesn’t burn of course) this afternoon though.

Yesterday the steady drizzle and fog/clouds sent me and the family off to the east end of the Gorge around 10am.  A huge improvement in just about 20 miles to the east.  Same thing today.  If you want sun quickly the next few hours, either head east to Cascade Locks and Hood River in the Gorge, or up to the Cascades Passes or Detroit Lake.  Anywhere east of there is starting sunny this morning.

La Nina Watch Issued

August 4, 2011

Still on vacation through Sunday, but just came across the tidbit from the Climate Prediction Center (NOAA).  I grabbed a few excerpts from their discussion here:

“The majority of ENSO models, and all multi-model average forecasts indicate ENSO-neutral will continue into the Northern Hemisphere fall 2011…

Beyond the early fall, the forecasts are less certain with half of the models persisting ENSO-neutral conditions continuously through early 2012. Along with a few other models, the latest runs from the NCEP Climate Forecast System (CFS) models predict La Niña to re-develop during the fall.  This forecast is also supported by the ongoing La Niña-like tropical atmosphere, subsurface temperature trends, and the historical tendency for significant wintertime La Niña episodes to be followed by relatively weaker La Niña episodes the following winter.

Therefore, ENSO-neutral is expected to continue into the Northern Hemisphere fall 2011, with ENSO-neutral or La Niña equally likely thereafter.”


So even though we are technically out of La Nina right now:

A:) some aspects of the global atmosphere still reflect La Nina conditions (a trough along the West Coast the past 5+ months???)

B:) we may slip back into at least weak La Nina conditions this upcoming winter.

Mid Vacation Pics

August 1, 2011

I’m on vacation for one more week…forecast and maps appear to confirm that I’m not missing much weatherwise.  Of course I was not in town for the Monday morning surprise lightning last week…ugh!

Here are two great viewer photos…first from Gabor Gardonyi near Lyle (last night), and a sunset shot of Mt. Hood from Chris Markes:
