Tuesday, November 15, 2011 at 10:19 am

10-day Snow Forecast:

Friday/Saturday, November 18-19

  • Wasatch above 6,000 feet, 8-16 inches possible
  • Bench locations, 3-7 inches possible
  • Valley Floor, 1-3 inches possible

Thursday/Friday, November 24-25

  • Wasatch above 6,000 feet, significant accumulations possible

Friday AM UPDATE: Really not much change to the forecast… everything still looking good.  Windy and mostly cloudy today ahead of the front with a possibility for rain showers in the valleys and snow showers in the mountains.  Front moves into the area during the evening with rain changing to snow in the valleys and heavy snow likely in the mountains through at least midnight.  Snow then breaks up into showers and perhaps lake-effect snow during the early Saturday morning hours. If solid lake effect band sets up southeast of the GSL, then enhanced snowfall totals will be possible.  Weak wave moves through on Sunday evening for a chance of light snow.  Ridging holds firm until late Thanksgiving day when another system approaches from the west.

Previous discussion:

Yesterday was a disappointing day for fans of deep snow here in Utah.  The 12z runs backed off on QPF and the 18z and 00z runs continued this trend.  A storm that looked like it was going to be a hefty one just 24 hours ago is looking to only be a moderate snow producer for the region.  Still better than nothing and Saturday will still be a decent powder day, although early season conditions exist.  Ready the P-tex.

Looking for around a foot of snow in the Cottonwoods… hoping for more but am not optimistic at this point as it looks to dry out much quicker after the passage of the front on Friday night.  The wildcard is lake-effect snow late Friday night and Saturday morning as a band could develop southeast of the lake.  If this takes place it could add a few inches to these totals however lake effect is notoriously difficult to predict.

Slight chance for light warm advection showers on Sunday on Monday for the cut-off low that will be dropping down the Cal coast and through the Desert SW/Northern Mexico.  Ridging then builds in strongly until the next deep trough approaches Thanksgiving day.  We’ll keep an eye on this as it has potential to be a significant snow storm.  Too far out for details as of now though.

Stay tuned…
