Repeat scenario?

Wednesday, December 11, 2013 at 6:57 am

The story for this week is rather gross, especially if you live in valleys, where inversions will continue to strengthen through Friday — leading to increasingly dense urban haze.    Up high, temps will continue to moderate with blue bird conditions likely today and tomorrow.

The next system will brush the far north on Friday into Friday night.  Models have been increasing QPF with this system, so it looks like a few flakes will fly in the northern Wasatch, although maximum accumulations look to stay around an inch or two mainly north of SLC.  The big question is will this front be strong enough to mix out the valleys… we’ll have to wait and see.

We will then dry out again for the weekend and into early next week, inversions will redevelop.  Next chance for a system continues to be late next week (Dec 19-20).  Both the GFS and EC have similar solutions with a large ridge of high pressure amplifying in the Eastern Pacific, allowing a very cold trough to dive into the Western Continental US.   Essentially, it looks to be an almost carbon copy of the freezing cold trough that just exited the region.  Still too early to know the exact strength and details, but it looks like there’s a good chance for another cold snap just before Christmas.


Instagram users:  I’ve received a couple emails from users saying that their instagram pictures using hashtag #wasatchsnowforecast aren’t showing up in our feed.  It seems that it only works if the hashtag is in the comments and not in the photo caption.  Sorry, this is bug we will try to fix.  Until then, please post your snow pictures using #wasatchsnowforecast in the comments.  Also, follow us if you aren’t already.  @wasatchsnowforecast  Thanks!

    So I assume that means snow! Hopefully there will be multiple storms this time before the cold air takes over?

    • Yeah, there should be some snow associated with the trough, but it’s still far too early to know how much.

    I just recently moved from the Delaware Valley this past summer and have finally settled along the Northern Wasatch in Farmington. Utah has been awesome so far and it has been great to finally get on the planks again. Along with my morning coffee, this is site continues to provide my daily fix concerning the weather around the Wasatch. As a novice weather bug, having only taken a lone meteorology class as a college elective, I appreciate the explanation of the science behind your forecasts. Thanks for all the effort that is put into this blog as you seem to be on top of your forecasts, despite the inherent unpredictability of weather. Anyone see the snow in Philly during the Eagles’ football game this past weekend? I plan to pick your brain as the season rolls on, but I feel that I have run long enough this morning. Thanks again! -Bryan

    I too enjoy reading your blog along with my morning coffee! Let’s hope the next storm will dump a ridiculous amount of powder for everyone to enjoy and clean up the air as well!

  • Thanks, Bryan. Hopefully we get some killer storms to forecast for you this winter!

      Looking forward to it! Been on the slopes a handful of times for some tune-up runs. Can’t wait to hit the real Utah POW! Thanks again.

  • Thanks, Mia!

    models sort of backed off of a storm on the 20th. I sure hope not!
