NOAA and this were wrong again for fall in the intermountain reg
So far so wrong. Both NOAA and Farmers Almanac had September- first week of October totally wrong and it's going to continue to be wrong. Both predicted warmer and drier than normal in the Pacific Northwest and the Rocky mountain ( inner mountain regions including Montana) and it's been anything but. Montana, Idaho, parts of Washington, Wyoming and the Dakota's are in a deep freeze as of October 8th and have had two record breaking winter storms already. Totally wrong.Why bother?
Beaver Dams
I went camping earlier (A few months back) and saw a beaver house by the water, it's layers were super thick this year, will it be a harsh winter this year?

Winter Forecast
I love checking with OFA each winter for a forecast. I'm in the inland Northwest/western Montana and old-timers around here is saying we are in for a brutal, record-breaking winter - cold temps and snowfall. So it will be interesting to see who is correct - OFA or the old-timers around here. Update in April (when winter usually gets over).
Well I guess we shouldn't listen to your forcast
Intermountain precipitation for September "0.5" Actual: 10/09/19 1.78"; 10/ 11/ 2019 3.56" OOOOPS missed that one!
Snow
I love the farmers almanac weather predictions but the only thing I wish it had was a prediction for the amount of snow we might get. That would be awesome.
Snow Know
Hi, Chelsea: Thanks for this comment. With our forecasts, you can find out when we expect the heaviest snows to fall, but we have no way to predict the actual totals—right now. But you can be sure that if there is a way, we will find it, and you will be the first to know! Well, you and 3 million others. Thanks again—that would indeed be awesome!
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.

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.
