Change in Weather Spokane/ Inland NW

My office faces huge Oak trees. Today I noticed the tops of the trees are changing for fall. Our weather has been mild & we've had more rain than normal so the trees aren't dry. There is a fir tree that's loaded with pine cones...It hasn't been this loaded for min of 5 years. My coworker went outside & noticed that the tops several oak trees are changing too. This change normally occurs September / October. I wonder if we're going to have a harsh winter??

OFA Services

Thank You, OFA! I truly appreciate your endeavour to provide weather data, gardening info, & all the wonderful information OFA shares! I agree people should not use OFA as a complaint board! The people complaining, have they paid for a specific service, that can be disputed in a litigation forum? I think NOT! OFA is not a platform to waste time, reading a ridiculous complaint! Respectfully, R.M. Villa, Blackfoot~Cree Nations Elder, Missoula, MT, USA.

May is very False and Untrue

We are in St. George Utah which is in intermountain South region. Right now up until May 22 we are suppose to be every day 15-20 degrees below normal and have chance of precip. everyday. Your prediction states we are suppose to be approx. 4 degrees above normal for the month of May Very Untrue

Comments

Almanac.com should remove the comments section. People only use it to complain, and honestly nobody using this site should be complaining. Nobody cares about their ridiculous complaints. They should use their freedom of choice to use another, far less accurate site, try being an active jacka$$ about social issues instead. Everyone thinks they should have a platform to release all their nonsense and/or ruin someone else's whole day. Get a grip people everything you think does not need to be known by all. Weather is hard to predict, if is inaccurate stay in bed until it's the way you want it.

Such complaining

My gosh, what's with all the complaints?! The OFA does a pretty decent job, but weather is not 100% predictable, and if you don't care for the site then just browse somewhere else. They do a lot better than most other sources. And it is a lot of work to put together so many long range forecasts, and two months for free. I think thats pretty good. I don't see any of the main stream weather sources putting out predictions months in advance. Geez people have become so spoiled and complain way too much, it gets so old!! I think The Old Farmer's Almanac is doing a great job!!!!

Thumbs UP!

Thanks for being appreciative and positive! We need more people with your great attitude!

Hey Shana

Sorry didn't mean to reply to your comment, I meant to hit leave comment. Nothing I said was in direct relation to your comment. Oops

Amen to that!

Preach on, Shanna!!!
There should be an app or a browser setting that would allow you to "disable comments" on any, all, or selected websites. If I made it, I'd call it the "Jackass Blocker" ... LOL!

With all these "keyboard warriors" and the "Negative Nancy" types on the internet nowadays, it's no wonder our societies are what they are.

Shameful to make such complaints and negative comments on a site like this ... specifically, pertaining to an article that is titled a "prediction of weather." Seeing as though it is an article PREDICTING weather over such a long period of time, AND the territory/region of which this prediction is for ... I'm totally impressed!!!!! So many of the cities listed in this region fall in the old adage of, "if you dont like the weather now, just wait 10/30/45 minutes." I live in Spokane, WA and have lived in Albuquerque, NM and traveled throughout this region and I think that trying to find any solid geographical common denominator from 1 city to the next would be difficult!! Then trying to predict the annual weather/climate patterns for such a variety of terrains?!!?!?!?! Mind blowing if you ask me!
I feel that for our region up here, their prediction from November 2018 to present day (July 13) is VERY ACCURATE! Theres a month or two in there that didnt happen exactly as they predicted ... but NEVER would I gripe and complain about it! Especially since that month or two may not have been spot-on outside my front door, but were probably spot on for another location in the ENTIRE REGION!!!!!!!

Local news weather anchors aren't even accurate 100% of the time trying to predict just the NEXT DAY'S forecast IN THEIR IMMEDIATE AREA.

UGH ...
PEOPLE.

Thank you for your complaints about complaints in the comment section. Made my day.

Chart vs Verbiage Predictions

Looking at February >>> Your Chart shows no precip of note and your verbiage up above states snowiest in Mid/Late February. Well. Oopsy on the chart because your verbiage is correct. Idaho and Western MT breaking all kinds of snow records. :) Might want to line up your chart and verbiage next time. :) I'm sure it was just an oversight.
