Forecast Discussion

What a great storm as history repeats itself with back-to-back years of double-digit snow totals in May.  This year the storm took place over 2 days, so double the enjoyment.  This year, however, is much better that last as there is much more terrain open at the resorts that are still open.

At Arapahoe Basin, the front side and some back side remain open, including Montezuma Bowl and The Beavers.  At Breckenridge, Peak 6 and 7 are open, including the alpine.  Winter Park has 60 trails open.  Get out and get some because this is likely it.  


Scattered snow showers this morning until around noon with maybe an inch or two more.  The winds will be from the northwest between 10-15 mph with occasional gusts up to 30 mph.  High Temperature today of 39.  


Tomorrow scattered snow showers in the morning with light winds.  Conditions will be good until at least the afternoon when rain is likely.  Right now, it looks like the rain will hold off until around 1 or 2 pm.  Temperatures will rise to around 45 degrees at base level, with 10,000 feet temperatures around 32 degrees, so there could be measurable snow up top and rain below.  Bring your squeegees!


Sunday morning may have fresh snow, between 1-3 and possibly more above 10,000 ft, as we have colder temperatures overnight.  I will monitor the models for changes, as of now it is between 1 and two tenths.  Base level temperatures Sunday will be around 42, with 10,000 ft temps around 32.  Light winds between 5-10 mph with gusts around 20.

Video of the LRC Cycle Comparison 22-23

This took a little more work than usual, because I couldn’t find a good format to compare the three cycles.  I finally settled on trimming each cycles width so that they could all fit on the screen.  

The video moves at a slow pace, but even with the slow pace, it is hard to see everything on the screen, so use the slider to move at your own pace. 

I am really proud of this video because first, it shows the fluctuation of the amplified pattern in each of the 3 cycles.  Second, the storms are closely synchronized.  With each frame advance, it is a quarter day.  You can see how the storms in each cycle closely follow the same track with slightly different timing.  Lastly, with the amplification, you can see how much the size and scope of the storms change.  Especially the California storms.  The amplification drops the storms to a more linear flow into the Sierra.
