Intermountain region

I have a real concern about your weather forecasts for the intermountain region. Back in the 1800s perhaps people in New England simply looked at this area as an amorphous "out west" and were not concerned with what may be happening to a few Indians and trappers 2000 miles away. So, to your early editors there was no difference between Fort Boise and Fort Tuscon. But this needs to change. The climactic difference between Flagstaff and Ontario, Oregon are never even remotely similar. Northern Idaho has completely different climate than Virginia City. Your forcast map covers an area over 1000 miles long and 800 miles wide. What you have now was "the Intermountain Region" needs to be divided into at least 4 different regions to even approach a scintilla of accuracy. Thanks for listening.

The Editors's picture

Hi, Steve: Thank you for this observation. Your points are very well taken and apply to many more regions than just the Intermountain, as you no doubt realize. We are constantly looking at ways to make our forecasts more localized, and comments like yours are always taken to heart and appreciated. Thanks again!

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??

Oak tree leaves changing

Hi Kimmy,
I believe the changing of tree leaves has to do with changes in amount of sun light, not in temperatures. (It’s the same with horses growing their winter hair coats) A thought is to talk to a certified horticulturist at your local nursery. Although they won’t know snowfall, they have a good background in weather r/t plant husbandry.

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.

I love weather watching! My Dad was a farmer and weather watcher. He's gone and how I miss sharing Nature's awesome power and the many lessons she brings with weather. His first lesson if you want to know what's happening with the weather for the day just look out the window and remember betting your life on a forecast is like jumping off a bridge and not knowing if the water deep enough. We can't complain about the changing weather because Nature is like us ladies, entitled to change our minds at any given moment. We so enjoy visiting your beautiful Blackfoot Nation in Montana, where we can truly see powerful and rapid weather changes. We've been visiting twice a year for decades.

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!
