Forecast for the Skyline Area Mountains

The storm that moved through Thursday and Friday added 5 to 8 inches of dense wind blown snow.
There are definitely areas that have fresh drifts.
These fresh drifts are what you want to look out for today. A person might be able to get something to crack out just below steep ridgelines.
The consequences if you trigger one of these fresh drifts are not all that serious.

Weather and Snow
Current Conditions: 3 to 4 inches more snow fell on Friday, mostly in the central and southern end of the range. Here are snow totals since Thursday:
  • Fairview Canyon/Lakes: 5 inches
  • Ephraim Canyon: 8 inches
  • 12 Mile Canyon: 15 inches (this is an outlier and I have a hard time believing that much snow fell but that is what the Mt Baldy Snotel weather station is reading)
The new snow was very wind blown on Thursday and quite dense as well. Some areas were stripped down to the old snow surface and others had deeper drifts. The wind from the north on Friday was very light. Temperatures only got into the 20s on Friday which kept the snow cold and dry at higher elevations. Temperatures dipped into the teens overnight. I found the riding conditions to be better than I anticipated.
Mountain Weather: We're back to springtime conditions now that the storm has passed. Today we'll see mostly clear skies and temperatures into the mid 30s today along the higher terrain and generally light northerly wind. Sunday looks fairly similar but slightly warmer. For the rest of the week, anticipate high temperatures in the 40s with a gradual warming trend. We'll probably see a few periods of clouds now and then but no significant storms are expected.

Description
As always, pay attention to how the new snow is behaving. Overall, conditions are not that dangerous. Here are a couple of things to watch for today:
  • Wind blown snow: The new snow was definitely beat up by the wind on Thursday. This formed some thick dense shallow slabs and some deeper drifts. I noted some cracking within these slabs and drifts on Friday. On very steep wind loaded slopes, mainly on the east half of the compass, you might find some pockets that will release if you provoke them. That said, I'm guessing that these will be fairly inconsequential.
  • Wet snow: The new snow will surely become wet today in most locations. We'll probably see some roller balls and perhaps some minor point release wet slides on the very steepest slopes. I'm not anticipating this to be a big threat. Just be aware that the new snow will get wet and somewhat unstable on the very steepest sunny slopes.
