Dear WeatherCat observers of the season's turning,

Northern California fell significantly short of normal rainfall last Winter.  However, the effects of this aren't completely realized until the end of Summer.  Trees "in the wild" suffer from insufficient water and lose their leaves much more quickly - before there is a chance for them to change color.  California has never been known for great Autumn displays but this year is especially bad.  Still, I observed this tree putting on a decent display:

Thus far in Northern California: October days have been hot, the fire threats very real, and Autumn weather remains a promise thus far not delivered.

Such are da' conditions that prevail,
. . . . . .

Once again, thank you for taking the time to photo-document your adventures and share with the rest of us.
Dear WeatherCat station caregivers,

WeatherCat dutifully sends me the reminder email to service my weather station on October 2nd.  I've been trying to complete this servicing since then.  The Weather Envoy battery fiasco was part of this effort.  Today, I finally got around to servicing the temperature humidity probe.  Since I replaced the PC case fan last spring I wasn't sure how much debris the new fan was bringing into the radiation shield and onto the sensor itself.  So felt it was necessary to take the assembly apart to be sure all was well.  I decided to just unplug the cable and let WeatherCat rack up the sensor errors.  Here is what the assembly looked like just off the bracket:

Not very dirty at all really.  Here is the upper part of the assembly where the fan is located:

Some dead insects and spider webs but nothing seriously obstructing the air flow.  I decided to use one of those compressed gas dusters to remove the bulk and settle at that.  Winter is coming, there is no point in cleaning beyond what will get dirty again in a hurry.  Finally here is the original Davis radiation shield disassembled:

It comes together with the components from the top of the photo and ending up with the final solid plate at the bottom of the photo.  My sensor isn't in the normal position that would have come from Davis because the fan required the sensor to be relocated (according to Davis at any rate.)

I need to buff the wax off of the collector cone and apply Rain-X to the interior surface of the cone.  Then at last my station will be fully serviced for Winter.  These days, I guess I can't complain about it taking 2 weeks!

I hope everyone else in the Northern Hemisphere has done their maintenance for Winter.  If not, time is definitely of the essence!

Cheers, Edouard

P.S. I had a surprise when I checked WeatherCat after reconnecting the temperature humidity probe.  It claimed the temperature had jumped 10 degrees from where it was when I started the servicing.  Here is a graph with the anomaly:

As you can tell from the photos, the sensor spent a bit of time in the sun while I was servicing the assembly.  That was enough to cause the apparent increase in temperature.  As you can see from the graph, the fan made quick work of getting the sensor back to the correct air temperature.

Here in the mountains of Northern Utah we have received an unprecedented 4.85 inches of precipitation since October 1. This is 4 times the monthly average and enough to reduce our area one status level in drought severity. Sure would be nice if this kept up although now nothing of the sort in the forecast.

Dear WeatherCat climate watchers,

This week the experts on such things made their latest pronouncement on the El Niņo - La Niņa situation.  The El Niņo Watch remains in effect as you can read here:

The key points are as follows:  "The majority of models in the IRI/CPC plume predict El Niņo to form during the fall and continue through the winter. The official forecast favors the formation of a weak El Niņo, consistent with the recent strengthening of westerly wind anomalies and positive temperature trends in the surface and subsurface ocean. In summary, El Niņo is favored to form in the next couple of months and continue through the Northern Hemisphere winter 2018-19 (70-75% chance; click CPC/IRI consensus forecast for the chance of each outcome for each 3-month period)."

Unfortunately exactly what this means for us mere inhabitants of planet Earth remains very much less clear.

Such are da' conditions that prevail, . . . . .

Cheers, Edouard

now I'm embarrassed...
Welcome to the club! I'm an expert at being embarrassed!  cmu:-) [blush]

As for the setting flipping, it was probably just a random cosmic ray. The setting is probably only one bit, so a single ray could change it easily. Of course, your being so close to the left-hand edge of the country may also be the problem. I hope you are on the east side of the San Andreas... [banghead] [rolleyes2]
Dear X-Air, Blick, and WeatherCat troubleshooters,

I thought it was plugged into the AC current
So, was it connected to AC?

Strangely enough not only was it plugged in, but a quick check confirms that the AC adapter is putting out acceptable voltage.  So I'm baffled on this one.

I assume you have a recent Java Runtime installed...

Well, yes and no.  The current Oracle Java is version 8.  However, WeatherLink can only run on version 6.  So I have both installed.

How frustrating. Let us know what Davis tells you.

Well I did send an email to Davis, but now I'm embarrassed about it.  The nature of that error message made be worry that somehow it wasn't being run in 32-bit mode.  Now I had checked it in the past since I had successfully run WeatherLink.  But just to be sure I double-checked and . . . .  run in 32-bit mode was no longer checked.    How this setting got changed - I have no clue . . . .

Once I checked that box, clunky WeatherLink did come to life and indeed my Weather Envoy was still set to my station settings.  So all is well.  That doesn't answer Bill's original question of why he wasn't able to get WeatherLink to work after all.  It is working on my MacBook Pro (Early 2011) and macOS 10.13.6.  Had Bill upgraded to Mojave?

In summary, at least some Macs can still run WeatherLink so that you can configure a Weather Envoy.  However, having a plan-B in mind is probably still a prudent precaution.

Oh well, . . .  Edouard

Dear Bill, Jos, Blick, and WeatherCat station caregivers,

I had a scare yesterday when I tried to replace the batteries in my Weather Envoy.  I thought it was plugged into the AC current, but it behaved as if power-cycled and it took a while to finally reconnect to my ISS and extra temperature humidity station.  Since the ISS is set on transmitter ID #2 and the temperature humidity station is set on ID #1, these have to be set on both the Davis console and the Envoy manually.

In order to try to understand what had happened, I tried to launch WeatherLink which is the only means I know about to set parameters on an Envoy.  However no matter what I tried to do I got this error:

Code: [Select]
java.lang.UnsatisfiedLinkError: /Applications/Mac OSX WeatherLink/ no suitable image found.  Did find: /Applications/Mac OSX WeatherLink/ no matching architecture in universal wrapper /Applications/Mac OSX WeatherLink/ no matching architecture in universal wrapper
It even generated this error on my old MacBook Pro running Mavericks that I use to adjust the electronic fuel injection parameters on my trusty wagon.  That's the oldest Mac I have around the house that is still running.

Since my Envoy came back to life as I had configured it, I'm back in business.  Alas, should there be a more serious problem, I would be forced to abandon the unit simply because I could no longer adjust its parameters.

I'm going to send an email to Davis and see what they have to say.  However, at this point I don't think any Mac user should consider buying a Weather Envoy.  Those of us with Weather Envoy devices should be contemplating a Plan-B.

Oh well, . . . . . Edouard  :(
