Week of Oct 22nd

Almanac was pretty accurate for Eastern WA. We’ve had rain all week.

Washington always rains of course

But the global warming is moving north every year and soon you in Washington will be like California

Just stop

Stop with the "global warming" fearmongering. Our planet has been cooling for over 2 decades now. NASA just told us that we are entering into a solar minimum that will be the closest thing to an ice age since the actual ice age, even calling for the nations of the world to burn MORE greehouse gasses in an effort to hyperheat the thermosphere. If you are going to push stuff like this, at least be somewhat knowledgeable about it.

One can’t preoct to the day

One can’t preoct to the day but being only 1 week off??? Not bad. Wish we had a torential snow storm this winter

Better than

Farmer almanac, while it isn’t always perfect it is fairly accurate. More so than Al Gore.

Comments

I too asked a question about inaccurate predictions. But never got a reply.

Predicted Snowfall for Bend and Sunriver this winter?

Looking more for predicted snow fall patterns going into November-December 2018 and into the New Year. Is there a way to get this prediction here or somewhere? Not just looking for rainfall patterns, specifically snow. Thanks,

Not so good

August was waaaayyyyyy off. How certain can we be about this coming winter's precipitation? Isn't there an El Nino brewing?

Way off mark...

Mid-Willamette Valley in Oregon.... Hot, hot, hot....
No cool and sunny weather -- so far this August. No showers...
Though we might dip down from 96F to 78F in a couple of days. "Might".... if the weather predictions at Accuweather are correct.
