SYNOPSIS:  News headlines include 20 inches of fresh at Whistler (50 inches in the past week), an epic 18 inch blower day for Mount Baker last week, and 15 inches at Loveland yesterday.  Sunday River Maine reported over 4 feet of fresh for the month of February.  The Cascades migrated to rain on Thursday while BC stayed in the cooler air reaping the rewards of some deep powder for those chasers that went north.  The week ahead looks very good for the Sierra and decent for the Rockies by late week.

SIERRA POWDER ALERT:   Heavy snow will break out from Tuesday night to Wednesday with 6000 foot snow levels. Expect 9-14 inches in many areas with Wednesday being the day to call in sick.  Light snow will continue into Thursday (2-5 additional).

CASCADES:   Wet Mank will migrate to powder Saturday night and Sunday as a fast moving cold front brings snow levels to 2,000 feet providing a quick shot of 5-10 inches to many areas.  The highest amounts will fall along a convergence zone near Stevens Pass on Sunday. Moderate to occasionally heavy snow likely for interior Washington and Idaho Sunday (Storm ski day).  Additional light snowfall is likely in the Cascades by Tuesday/Wednesday with generally high pressure for the extended until March 11th (Next decent storm).

ROCKIES:  There are several systems to watch this week.  Sunday afternoon will see an increase of medium density snowfall favoring the Northern Wasatch (Snowbasin, Powder), Tetons, and most of central and southern zones of Montana (BIg Sky- Bridger).   Expect a quick 5-8 inches in most locations with  higher amounts in the Tetons and southern Montana (6-11) where colder air enhances snowfall.    The Central Wasatch (Alta, Snowbird) will generally see 4-8 inch amounts of medium density (Sunday PM through Monday AM).

Colorado will see snow Sunday evening through Monday night with a focus from Steamboat through the northern San Juan’s and Aspen.  This shifts towards the Divide along  I-70 late Monday morning. .  I would expect a general trend of 4-8 inches with perhaps more over Steamboat (Cold Front lingers along the Wyoming border) and  the Northern San Juan’s.   The past several storms have under promised and over delivered with sneak up powder days and missed powder alerts. Let’s hope for the same by Monday evening.

EXTENDED POWDER FORECAST:   Expect additional snowfall over the Rockies by late week with moderate amounts possible Wednesday evening from Central Idaho, Tetons, and Wasatch ranges through Thursday.  Colorado will see light snow during this period.  The long range models depict a strong storm moving over the 4 corners of the San Juan’s by next weekend and extending up into the Front Range including Summit County by late Saturday/Sunday.

Finally, the bad news is that Powderchaser is taking some time off with a torn MCL.  If I am on the slopes it is against Doctors orders. From past experience Powder rules all emotions so I might be playing medical hooky and jumping on some fluff within the next few weeks!  You might notice a slight decrease of euphoria on my posts. Depression possible by late next week?

Enjoy the new snow if you are in BC today, Sierra Wednesday, and the Rockies both Monday and Thursday this week!
