.4 so far. I assume the cold storms followed by warm storms and vice versa makes avalanche control interesting ?

Thin, early season snowpacks with cold temps, can lead to development of weak layers in the snowpack. Warm storms bring wet heavy snow that can load weak layers. The historic avalanche at Alpine Meadows comes to mind. The folks doing control work are experts but we all need to be aware of these conditions if going into the backcountry.
 
SPEAKING OF WEATHER:
I'm enjoying the Ventusky app for forecasting weather -- all parameters -- over large regions. It's helped me decide where I can go to escape "winter" (the conditions, not the season).
IMG_20240120_114141.jpg
It displays isotherms (aka, "heat maps") for temperature, wind, whatever... as well as scattered numerical values. Lots of parameters to choose from for display:
IMG_20240120_115338.jpg
What originally caught my eye was the animated wind direction and speed indicators. That doesn't show in these still screenshots, but the arrows move in the app.

At the bottom of the app screen you can adjust the date and time sliders for the target time of the displayed forecast parameters.

And you can zoom way in (pinch to zoom) on an area for a more precise location forecast.

It's white and getting whiter at my place this afternoon:


Not a lot to come here in town, 1 - 3 inches off and on but with melting, too, but there is a Winter Storm Warning in effect, especially for the Cascades.

Still a sweepable amount on my front steps;

Aren't apps like that the best! I will check that one out. I currently use a similar one called Windy.com

https://www.windy.com/?37.031,-122.120,5

Windy has served as a reliable tool when forecasting the conditions out at sea. I also use it to check the wind and weather before (and during) camping adventures.

I am a big fan of Windy.com. Well worth the ~$18 per year subscription.
 
Real winter is returning the end of this week and through the weekend, just in time for Spring. :)

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)...
A deep, cold upper level trough will begin to move closer to the
region. Widespread precipitation is expected to begin Thursday
afternoon/evening and persist through Sunday morning before
gradually tapering off. Periods of moderate to heavy rainfall,
heavy mountain snow, and gusty winds are all likely impacts from
this storm system. Most of the heaviest precipitation is still
forecast to be in the mountains, but the Valley will likely
receive moderate rainfall impacts and gusty winds.

Current NBM probabilities for snowfall amounts exceeding 36"
inches in are 70-100% from Thursday morning to early Sunday
morning along I-80 from Blue Canyon to Donner Pass, with similar
probabilities along HWY-50 from Kyburz to Twin Bridges.
Accumulating snowfall is also expected along I-5 in Shasta County,
near Sims and areas northward. Snow levels are currently forecast
to be 4500-5500 feet Thursday morning and lower to around
2000-3000 feet Saturday. There is a possibility of snow levels
reaching lower than 2000 feet, as this system is much colder than
some of our previous events.
 
As the predicted storm gets closer, it is looking to be quite significant -

National Weather Service Sacramento CA
232 AM PST Tue Feb 27 2024

.Synopsis...
Active pattern returns late week into next weekend
bringing widespread precipitation, extremely heavy mountain snow,
strong winds, and low elevation (1500-3000) snow accumulations.
Following this system, expect near freezing Valley temps and AM
frost. &&

.Discussion...today through Friday.

Key points of late week storm:

* Extremely heavy snow is expected late this week, heaviest Friday
and Friday night. Storm total snowfall from Thursday into early
Sunday is currently projected at 5 to 9+ feet for elevations
above 5,000 feet.

* Significant snow accumulations are expected above 3,000 feet

* Cold air will drop snow levels down to 2,000 by the weekend,
with light accumulations possible at those levels.

* Wind gusts to 50 to 60 mph are expected over the mountains. Snow
rates of 2-3+" per hour are possible. These will combine to
bring whiteout conditions at times.

* Mountain travel will be nearly impossible, especially Friday.

* Strong winds are in the forecast Thursday through Friday in the
Valley, gusting from 35 to 55 mph from Marysville northward.
 
Southern Minnesota needs snow (actually water in any form).
We are on a temperature roller coaster: 63º yesterday (February!), 7º tomorrow, in the 50's on Thursday, then high below freezing next Tuesday. No moisture til next week, and not much then.
