Atmospheric Pressure Explains a Wimpy King Tide Plus Cold Air Ahead

 In my podcast today, I spend the second segment talking in depth about atmospheric pressure.  That information is particularly important this week: 

A very large astronomical King Tide will be reduced considerably by much higher than normal atmospheric pressure.

Normal pressure at sea level is approximately 1013 hPa (hPa is the metric unit of pressure).

This week the pressure is forecast to be around 1030-1035 hPa! (see forecast below).

Such high pressure will reduce the high tide by roughly 7 inches.   As you can see below, the water level predictions (blue lines) are substantially less than observed (red lines).   This situation should continue for the next few days.


As described in the first part of the podcast, a weak front will move through on Monday morning, followed by a dry week.

But excitement will await next weekend, as very cold air moves over the region (see forecast of lower atmosphere temperatures and sea level pressure for 1 PM Sunday).   Blue colors are cold enough for snow.


Will there be lowlands snow over western Washington and Oregon?  Stay tuned...

Why so little lightning in the Pacific Northwest? And a very nice weekend ahead.

Image
During the past 24-hours, there have been a few lightning strokes over the region (see below) but nothing to write home about (see below). It turns out that the Pacific Northwest and the remainder of the West Coast have some of the lowest frequencies of thunderstorms in the entire country (see below). But why?    My podcast provides the answer. And I also give the weekend forecast....and I think most will like what I have to say.

The Time of Year You Can See the Air Move

Image
  Most of the time, you can not see the air move.   You can feel it, but the complex, turbulent motions are invisible to you, except when it interacts with leaves and branches on trees and plants. But for a few weeks of the year, the sky is full of small, cotton-like tuffs that like a natural MRI machine reveals the complex three-dimensional motions of the atmosphere.   Cottonwood season.  And we right in the middle of it.   Being cottonwood aware is of particular value this year.  It reveals the active dispersion and movement of air that makes the outdoors essentially COVID safe, and thus should be of some comfort for those nervous about transmission outside. Cottonwood seeds are embedded in small cotton-like fibers.   A million seeds weigh about 3 pounds.  Yes, each seed and tuff weights about .000003 pounds.   And that fact, plus the cottonwood tuff, means that these seeds fall VERY, VERY, VERY slowly.   So slowly that they are excellent markers for the three-dimensional flow of the

A Much Colder Than Normal April: But How Unusual?

Image
  April was a chilly month over the Northwest, but how chilly?     It turns out the answer depends on where you are located. The difference between this April's temperatures from normal across Washington State (below) shows that the entire state was well below normal.  The eastern side of the state was particularly frigid:  some areas were more than 6 degrees below normal.   Considering the west side of the state, the April mean temperatures at SeaTac Airport are plotted below.   This April was the coolest since 2011. April 2020 was in 15th place for the coolest April since the mid-1940s and was a bit more than 4F below normal.  So if you felt that you were cheated out of normal spring warmth...you are right. But if you really wanted to experience extraordinary April cold you had to be east of the Cascade crest. Consider Yakima.  Wow.  It had the third coldest April temperature since the mid-1940s.   And the all-time record in 1955 was only slightly colder. If you want a longer-te
