Question for Editors

Is it true that the PNW is one of the hardest places in the world to predict the weather?

Weather forecasting in PNW

Not really. If you can see Mt. Rainier, it's going to rain. If you can't see Mt. Rainier, it's already raining.

Shanda sometimes it is hard

Shanda sometimes it is hard to predict PNW weather. I say so myself.

Weather for first week in May

Well the Almanac says rainy periods and cool for May 1-11th, but the local weather is predicting we get to the high 80s by the 11th. It has been in the high 60's to mid 70's so far this month. I hope this doesn't mean we are in for a brutal summer again.

Brutal Summer

Well Lydia. Buckle up for half brutal summer, we are going to get some days into mid 100"s. Between 100 & 107. Hopefully less fire hazard.

Accuracies of the Almanac.

In Eugene almost 90 during that week. So if they got that backward, such as we are now getting the weather they predicted for the first 11 days of May, could it mean that the other weeks are also wrong and it’s a crap shoot as to what Mother Nature decides to have us endure?? Just sayin’!

Almanac weather forecasts totally redundant

Were the weather forecasts in this Almanac written in 1792? They are definitely redundant for the Willamette Valley in the Pacific Northwest where extreme heat waves have plagued us during last 4 summers. Ironically the Almanac does predict high heat for forthcoming June only, but weather bureaus say our June will be below average in temperature, with heat waves again in July, August and maybe even September. By heat waves I mean week-long temperatures as high as 100 days and 80 at nite (no overnite reprieve).

Below Average Snowfall?

I had to ruefully smile and shake my head when reading the prediction of “below average snowfall” for our area. The Kitsap Peninsula was paralyzed by more snow than we’ve experienced for over 100 years — with Bremerton receiving 22” and some parts of Bainbridge Island getting 3 feet of snow. Usually we have maybe 5” for the winter.

Shake your head? If you look

Shake your head? If you look at the chart and surely no one could’ve predicted record snow fall but it does say well below normal temps for feb and above normal precip

Right?! Pretty much all of BC

Right?! Pretty much all of BC had more snow, but Vancouver Island was really bad. It used to be, 30 years ago or so, winter was all about rain and more rain. In recent years, it's been snow and more snow. Ever since SnowmaGedden in 1996, snowfall in November and in January/February has become more regular and more intense. This year, it was the same story as in the Kitsap peninsula. A friend missed three days of work in a row and then spent an hour and a half digging her car out so she could get to work. This was at the ocean, where the snowfall is always lower. So, I agree that the weather is not what they say here.
