@HartungWx @CliffMass guys...you are not correct. If the reservoirs are nearly full in mid-june, there will be enough water for AG. Remember, snowpack melt is generally over by the end of June. I have confirmed my analysis with local hydrologists. ..cliff

@LocalClim @CliffMass The reserviors being full is a positive but the lack of snowpack and therefore lack of inflows means they are going to have to either draft the reserviors rapidly to meet water demand or reduce demand to maintain reservoir levels for recreation/safety.

The Heaviest Precipitation of the Year Ahead? cliffmass.blogspot.com/2026/05/the-he…

@StewarrMark @CliffMass Mark...you are looking at the wrong place...go to the windward side of the mountains!...and a lot more is coming later this week..cliff

@CliffMass If this is substantial then I’m a purple one eyed platypus..

Substantial Precipitation Has Returned to the Pacific Northwest: What Has Changed? cliffmass.blogspot.com/2026/05/substa…

@HartungWx @CliffMass Garret... the inflow is not so important because the reservoirs are nearly full. Furthermore, these predictions are clearly wrong...seem to be missing the precipitation next week...cliff

@CliffMass Wow inflow into Cle Elum might get near the 10th percentile (90% exceedence) with this “scary wet” period coming up. Looking like some of the worst inflows into those reservoirs on record over the summer due to lack of snowpack. Drought seems warented given those inflow.

@SeattleWXGuy @Rob32cc @The_Weatherman2 @CliffMass Michael...you are fundamentally getting this wrong. Really. Call me and I will explain it to you. ..cliff

@Rob32cc @The_Weatherman2 @CliffMass Every scientific paper claims at least as much of the water supply in the west is from snowpack, whats so hard to understand about whats being said here and what virtually every scientists says ? Part of your problem is that you guys think that drought means death and destruction

Why the Washington Drought Emergency Should Be Dropped Immediately cliffmass.blogspot.com/2026/05/why-wa…

@SeattleWXGuy @CliffMass Seriously, Michael....call me, and I will explain it to you. How much of the area that drains into the reservoir is not relevant. The water supply is relevant.. and that will be ok during the summer because the reservoirs are topped off..cliff

@LocalClim @CliffMass

Funnel Cloud in the Lowlands and Substational Snow in the Mountains cliffmass.blogspot.com/2026/05/funnel…

@SeattleWXGuy @CliffMass Michael...you are totally wrong on this. The water supply volume DOES NOT INCLUDE DAM RELEASES. During the summer, snow melt is not important. Really, you have this completely wrong. TALK TO THE RIVER FORECAST FOLKS. Seriously...cliff

@CliffMass You continuing to repeat this misinformation on snowpack and reservoirs isn't going to change reality. If you are interested in the facts and how our small reservoir system works vs snowpack, check this out ecology.wa.gov/blog/may-2026/…

@SeattleWXGuy @CliffMass Michael...you are totally wrong on this. The water supply volume DOES NOT INCLUDE DAM RELEASES. During the summer, snow melt is not important. Really, you have this completely wrong. TALK TO THE RIVER FORECAST FOLKS. Seriously...cliff

@CliffMass Stream flow forecasts continue to be well below normal because of low snowpack, reservoirs cannot sustain us through a summer. Check out the Yakima data below

@SeattleWXGuy @CliffMass Michael....look at the cloudiness information and you will see that I am correct. Call me and can explain it to you...cliff

@LocalClim @CliffMass No, you wont, because thats NOT what the data shows. Check out Solar Radiation numbers for Seattle May vs June. June was higher every month since 2014 except for one year.

June Gloom Comes Early cliffmass.blogspot.com/2026/05/june-g…

@SeattleWXGuy @CliffMass michael...you are not correct in this. You are looking at the wrong thing...look at radiation reaching the surface and you will see your error. Perhaps my next blog!..cliff

@CliffMass If you are interested in the actual facts: Seattle gets increasingly more sun during the spring months, peaking in July, lowest in December. There is no June gloom on average for Seattle and its one of our sunniest months behind July and August!

@USWeatherExpert @RyanWeather I suspect you mean declining.....

@RyanWeather The problem of deciding warning accuracy has existed since 2012.

After facing criticism from Congress and a former high ranking NOAA official for botching severe weather forecasts, the National Weather Service announced a hiring spree. Employees are burned out. nytimes.com/2026/05/06/cli…

@SeattleWXGuy @CliffMass michael...you are not understanding what I am saying. Of course, we can get warmer days at the end of May, but we OFTEN see a spike in the first half followed by cooler temperatures as "june gloom" sets in. ...cliff

@CliffMass Cliff Writes: "So why do we often see a spike in temperatures in early May followed by cooling?" The answer you ask?: WE DONT. It's Complete nonsense, with the red and orange lines you can clearly see that avg temperatures and record highs clearly go UP during the month of May

Warm But Not Hot cliffmass.blogspot.com/2026/04/warm-b…

@SeattleWXGuy @CliffMass michael...did you read the paper? There are some serious issues with it. I can explain them if you are interested...cliff

Will 2026 Be An Above-Normal Wildfire Year in Washington State? cliffmass.blogspot.com/2026/04/will-2…

@SeattleWXGuy @CliffMass Michael. What you have written is not supported by the facts. 50% snowpack is very useful. Reservoir storage is way above normal. More rain is coming. PLEASE, do the math and you will see we will be fine. And we don't 100% storage to support most of the crops. 2025 proved this

@CliffMass Precipitation in the form of winter rain doesn't help when farmer's need it, reservoirs way too small, snowpack of 50% isn't substantial, it's very low, in fact each acre holds about 270,000 gallons less water this year vs normal, also streamflows are forecast below normal.

When a Drought NOT a Drought? cliffmass.blogspot.com/2026/04/when-d…

@SeattleWXGuy @CliffMass You need to read the literature (I have).Many of the recent papers support the hypothesis that this eruption played a critical role in the warming.I have published several papers on this topic and have looked at the data.I believe that water vapor injection was critical.

Major Global Cooling of the Past Two Years and the Big U.S. Heatwave Last Month. Climate Change? cliffmass.blogspot.com/2026/04/major-…

@SeattleWXGuy @CliffMass Michael...you are quite wrong about this. This paper actually supports my analysis, finding little connection between snowpack and wildfire over the Pacific Northwest. Did you bother to carefully read the paper and its supplements? You should..cliff

@CliffMass More peer reviewed work that disagrees with your blog, just published 6 days ago in fact iopscience.iop.org/article/10.108…

@SeattleWXGuy @CliffMass Michael... unfortunately, there are significant errors in this article. By the way, you are blocking me from commenting on your twitter feed. People interested in the truth do not block others with different viewpoints. Scientists do not block others....cliff

@CliffMass Here is an article explaining from Karin Bumbaco , M.S. Deputy State Climatologist as to why we are likely headed to Drought this year: yakimaherald.com/news/northwest…

One Day "Heat Wave" Followed by a Week of Dry Weather cliffmass.blogspot.com/2026/01/one-da…

@SeattleWXGuy @UForspam23773 @CliffMass No, Michael, I did not say that. Happy to talk to you about your forecast in private.

@LocalClim @UForspam23773 @CliffMass So you thought I did a good job on the storm, thank you then.

The Windstorm That Never Came: A Failure of Communication cliffmass.blogspot.com/2025/12/the-wi…

@SeattleWXGuy @UForspam23773 @CliffMass Michael..truth matters and you are not providing it. First, I have NEVER mentioned you in my blog. Want proof? Do a search for your name. I have never referred to you. Secondly, my forecast was NOT a bust...I went for 40-50 mph, which was quite good (I checked the data) cliff

@UForspam23773 @CliffMass He called me and many others out in this blog. I didnt call him out when he had forecast bust after forecast bust this month. The common denominator is Cliff and his nasty approach, not me defending myself and others.

@KSeattleWeather You were entirely correct...and I am sorry you were in the firing line. And yes, the NAM is not reliable around here.

I was raked over the coals for saying I didn’t think a windstorm would happen. One of the worst social media experiences I’ve had. Agree with Cliff here (and I’m NOT a meteorologist, just a Seattle weather nerd!)
