Regional Heat Wave and My Weather Discussion

My blog on KNKX is found here.
I would like to thank all of you for your support. Together we will protect freedom of speech and respect for diversity of viewpoints.
______________________________________

Temperatures are going to zoom into the 90s on Sunday and I discuss the weather situation below.

A major ridge will develop over the western U.S. (see forecast upper-level map for 5  PM Sunday).  Such a ridge is associated with sinking, warm air and very dry conditions.


Easterly flow will develop over the Cascades, bring enhanced warming on the western slopes and a thermal trough of heat-driven low pressure will move northward out of California.  The surface weather map predicted for 8 PM Saturday illustrates the very warm pattern.   Wow.  Very warm temperatures over Oregon, with the Willamette Valley getting over 100F.  You can see the thermal low extending into SW Washington.


But it will be Sunday that will be the warmest day over Puget Sound, followed by cooling on Monday.  All explained in my video.

Update:  the audio is fine...but there is problem with the video...  I will redo it later.  It will take time for me to get this right!

  5. Nicely done Cliff, in depth and much more informative than the few minutes on KNKX. Definitely the best weather blog anywhere!

  6. I’ve always been confused by "ridging". Is the height of the atmosphere heaping up like a mountain ridge, or it is more of a metaphor for the northward bend of pressure lines that look like a topographic ridge on a topo map?

    1. You might appreciate Dr Mass' book on the weather of the Pacific Northwest. I need to refer to it often when reading his weather blogs. Good stuff.

  20. Thanks Cliff. I really enjoyed the video and am sending it to my 13 year old granddaughter. With schools going to online education this fall, presentations like this add extra to a student's education.

  25. Cliff: Thank you for the video. I like it better than the KNKX Friday morning discussion. It helps having your explanation to go along with the charts. Very high data-to-ink ratio!

    I wish that I had signed up for a monthly donation to KNKX during their recent pledge drive. Then I'd be able to shut it off! Thank you.

  26. The map showing wind speed and direction does not include Whatcom County for good reason as the northerlies Cliff discussed have generally not materialized here - at least not of the magnitude of those shown on the wind speed/direction map. At my location in NW Bellingham, the maximum gust I've measured today is 12 mph from the west. It's also been considerably warmer here than forecast (Weather Channel). Yesterday's maximum temperature was 77F and today's is 85F. Both values are more than 5 degrees above the forecast maximum temperatures. Additionally, it's been somewhat muggy here. The maximum dew point temperature today was 65F which contributed to a maximum "feels like" temperature of 99F. Central AC is delightful to have today and will be down right essential tomorrow!
