Spring Pow on the Doorstep

Tuesday, April 7, 2015 at 7:17 am


Warm and windy on Tuesday ahead a Spring storm that will bring snow to the mountains of Northern Utah on Wednesday.


Strong southwesterly flow developing today.  Winds will increase as the main low starts pushing east from its current location off the California coast.  You can see moisture and clouds increasing in this satellite image:


There may be a few mostly high elevation showers today from time to time, but the main system and accumulating snowfall will arrive early Wednesday morning.  Latest 12z NAM showing snow starting at about 6am:


The 12z NAM usually provides a good low end of snowfall amounts.  The 4km NAM, a higher resolution version, often provides the upper limits of the snowfall range:


You can see it paints 14″ of snow for Upper LCC by Thursday morning.

Snow should continue most of the day Wednesday, tapering off to showers Wednesday evening.  Wednesday will be a storm day free refills while Thursday will be a first chair = best chair type of day.  There are some indications of a secondary impulse Thursday afternoon that could bring a couple more inches.

Total accumulations:

For the Cottonwoods, it looks like 5-10″ is likely during the day Wednesday.  Additional showers Wednesday night and Thursday will add several inches.  I think by Friday morning 7-14″ is likely.

For Park City resorts, the heaviest snow will fall during the day on Wednesday with 4-8″.  Additional showers Wed night & Thurs will add a bit.  Total accumulations of 5-10″ possible on the upper mountain.  Base elevations of PC will likely see 2-5″.

Long range:

We clear out Friday and Saturday.  Next system pushes in Saturday night into Sunday.  Models have moved much closer together in how they handle this system.  Right now it looks like a weak system that mostly just grazes Northern Utah.  Sunday is closing day for many resorts. It would be nice to get a bit more than just a few inches, but right now I don’t think that’s likely to occur.

GFS and EC both keep us in generally an active pattern next week with another system possible middle of next week.  April is trying hard to make up for its preceding 3 months…

    How much rain can the valleys expect? I’m a farmer and I’ve hung up my snowboard for the year and am looking for some rain to get our crops to start growing.

    What great timing – I was taking a little staycation as I have some family visiting an was not too excited considering the past conditions, but today at solitude has been the best snow in two weeks. Can’t wait till tomorrow!

    Agreed! What are the best “sick” day(s)? And do you think next week might be a better “sick” time?
