Snow
I live in the Tri-Cities, and the first time it snowed was on Dec. 1. None of these predictions are really right.
Snow
Any chance for snow for Christmas????
Winter 2019/2020
I hear on tv that calif.ariz.nev.utah.oregon.wash state. Others will not see winter it is expected to alot warmer than normal above average no rain or snow in forecast at all mostly sunny clear skies eastern part of u.s. will be below average colder.. warmer here. In the west it will start getting cool at nights but has been on 20s at night will push Into low 40s warm means west could see Indian summer returns to states due to no el nino or la nina it's dead wont produce anything stay clear skies all the way into summer 2020 not a drop of bv rain or snow at all
So. Cal. Mountains
I live in southern California, but 7000 feet up, in the mountains. It helps to know the rainfall expected "down the hill," but I'd love to see what we're expecting in regards to snow up here--not specific inches, or anything, but whether to expect a "bad winter" or not. Any way to judge our snowfall from the rainfall down below us???
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?
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.
