NOAA and Farmers Almanac are accurate

Frank Fontaine I am not sure where you are getting your info. I am not sure where you live either. I am here in Idaho I wish winter was starting as in snow coming and not just high in the mountains. We are having rainy days. No snow here yet, we have had a few frosts but nothing more than that. I have gone by Farmers Almanac and NOAA for my weather I have gotten accurate weather. I am not sure of this deep freeze you are talking about maybe it is happening in a different part of Idaho than what I am in. The northern part is still green and beautiful.

Early winter storms

Where in Idaho are you is the question. Here in Spokane we got snow in September and again in October and had freezes as low as 13°f. North Idaho got same. Frank's information is coming from his direct experience, which matches mine.

Frank I AGREE

Frank your comment was 100% correct!!

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?

In North Idaho, the weather

In North Idaho, the weather was exactly how Frank Fontaine described. Two snow storms, one in late September and the other just a week and a half later. I’ve heard anywhere from expecting 200” of snow for Coeur d Alene area, to warmer than normal temps, to average precipitation. It really is just a guessing game at this point.

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

The Editors's picture

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.
