No, you are the problem

The problem is people like you, the attitude you are taking is what is ruining societies everywhere. Nobody can say anything cause you might not want to hear it because it offends your sensibilities, as I told the last person, GET OVER YOURSELF. We do not need your lectures, we do not care about your weak view point of view that people should all go around saying sorry for every little tiny thing they do. You don't need to read the comments, If you think they are great leave your positive review and go, move on with your life instead of stopping to type a half chapter tooting your own horn about how you don't like how people toot their own horn. Can none of you see how hypocritical you all are? "Let's make posts complaining about people who complain" and now you got me complaining about posts which contain complaints about complainers, you see how incredibly redundant it all is? Life can't be constant positivity, it's simply not how the world works. If people aren't allowed to vote with their voice and let services know when they are not performing as expected all we will have are completely useless services that will be entirely valueless because we just sit by and watch as they decline because people like you don't want to have to read negative reviews. Your viewpoint is absolutely inane.

Comment complaints

Thank you for your complaints about complaints in the comment section. Made my day.

Coming late to the conversation

So most definitely typed the wrong date by accident but as far as my area ended up pretty accurate to the projection, yeah some of the dates were off and it made it sound a bit different then it actually was. That being said the order in which the weather changed was exactly the same and the dates somewhat align with what was predicted.

Chart vs Verbiage Predictions

Looking at February >>> Your Chart shows no precip of note and your verbiage up above states snowiest in Mid/Late February. Well. Oopsy on the chart because your verbiage is correct. Idaho and Western MT breaking all kinds of snow records. :) Might want to line up your chart and verbiage next time. :) I'm sure it was just an oversight.

precip chart

The Editors's picture

Donna, the charts for each region correspond with the monthly predictions for the region in temp and precip; it is a visual representation. For February, we predicted “(avg.)” precip. On the chart, that is represented as a flat line/nothing above or below the line. The precip does not include snow, btw, either. We did predict above-normal snowfall in northern portions of this region for the season, so so far, pretty good, it sounds like. Thanks for your comments.

Frozen Flathead

Funny that flathead lake hasn't frozen over since my eldest was born 21 winters ago either!!! The old farmers have, lets a difficult time predicting future forecasts with over 7 billion people on the planet constantly changing current conditions... oversight or lack of precedent?

Constant change, LOL!

The climate/weather has been constantly changing for billions of years, it didn't just start all of a sudden. That is how it works. It will constantly change for the rest of time also. There is no solid evidence that shows any cause, and there are hundreds if not thousands of variables that account for it. So what are you even talking about?

Weather

Hi, Where is St. George Utah under (southern Utah) which section, all I know is its showing above normal temps December thru June which so far is totally wrong since October we have had almost every day 10-15 degrees below normal temps. and above normal precip. The weather for Feb. (next 10 days) so far is mostly suppose to be in 40's and 50's where normal average is usually low 60's

Idaho Falls

Is Idaho Falls considered central or north when reading these?

Idaho Falls

The Editors's picture

Idaho Falls would be considered central, but because it is also in the northern portion of the region, it would be wise to consider the forecasts for both North and Central.
