The Updated weather.utah.edu


Updates to weather.utah.edu went in today.  In addition to being on a new server, the site has a new look and feel matching current University of Utah branding and has better fonts, more descriptive alternative text, keyboard navigation, etc. 

Bookmarks from the old site have a good chance of working, but if they are broke, you may need to update them.  

Much thanks to our partners at the University of Utah Center for High Performance Computing (CHPC) for making this possible.  Thanks as well to data and software providers (NCEP, ECMWF, Penn State, Iowa State, AWS, Unidata), not to mention developers of the many python packages we use, students and other collaborators who have helped with code development, and OpenAI Codex which I've been using for code updates.  It takes a village to build a site like this.  

We hope to eventually have a 1-2 month archive available through the "View a Different Run" option at the top for several models.  Right now it might go back 3 weeks or so. 

We're still monitoring and making tweaks here and there, but products appear to be flowing and updating, but if you see any issues in the next couple of days, report them in the comments below.  

Update Oct 2:

So far so good.  The RRFS Snow Ensemble is not currently available and hasn't been even on the old web site for several weeks due to changes in how the output from that ensemble is stored on AWS.  I simply haven't had the time to update and debug the code to deal with this.  The RRFS is now scheduled to become operational on October 14.  This is delayed from August 31 as originally planned.

    I really like the improved HRRR-Snow Experimental Time Series plot. More data and more easily viewed. Thank you, Jim!

      That's been there for a while, but maybe hidden. The web page needs to be updated to the look and feel of weather.utah.edu but that's not a critical priority at the moment.

    I also really like the HRRR-Snow Time Series data which now processes faster. When the HRRR is replaced by the RRFS I would love to see it continue as the RRFS-Snow Time Series. Thanks for all you do!

America's Rainiest City?

Image
Ketchikan, Alaska is known for two things: salmon and rain.  I know this well as I have been here several times visiting family.  The combination of wind and rain often makes it feel like you are living in a car wash. Ketchikan, which is located on the inland passage in southeast Alaska, has fully embraced it's status at the Rain City .  It proudly displays a "liquid sunshine gauge" on the boat dock showing just how wet it is. A closeup shows that they claim an average rainfall of 12.5 ft (150") per year.    That's a lot of rain and, perhaps not surprisingly, Ketchikan is widely promoted as the rainiest city in America (e.g., destimationalaska.com ).  Being a meteorologist, I began to wonder if this was really the case.  There are the usual challenges in evaluating such a claim.  What is meant by a city?  What is the period of record?  Is the data reliable?  Etc... For the purposes of this post, we'll concentrate on clima...

Escape from Utah

Image
In an effort to improve the snowfall situation in the Wasatch Range, I have left Utah for the rest of the cool season.   I'm serving as a guest professor at the University of Innsbruck for their so-called summer semester, which actually runs from March to June.  We arrived here on Wednesday.  It's been mild and sunny here with high temperatures above 10°C (no °F here) in Innsbruck each day.  Today I skied with some friends at Stubai Glacier, which reaches over 3000 meters elevation, to escape the heat.  It was a spectacular day.   Like Utah, Austria has had a largely crap snow season and the current warm spell isn't helping.  The snowpack on south aspects is pretty much non-existent below 1500 meters and in some areas much higher than that.  The snowpack is meager where it exists, even at the highest elevations.  Glacier-mounted lift towers today were on large domes of ice.  These are usually covered with white blankets (I'm no...
