🚨 Snow Lab Big Give Alert 🚨
We’re raising funds for 2 important things:
🎓 Training the next generation of snow scientists
🚙 A much-needed 4×4 field vehicle
Because snow science requires students… and occasionally a truck.
⏰ Ends tonight at 9pm
❄️ Support us: givingday.berkeley.edu/giving-day/1...
2/2 Certainly not ideal from a water storage perspective. Not much in the forecast in terms of precipitation, unfortunately.
*SWE is the amount of water that can be obtained by melting the snowpack.

2/26/26 10:50am:
As expected, the ~1.7" increase in snow water equivalent (SWE)* from this week's rain was temporary and exited through the bottom of the snowpack.
In fact, the warm storm melted some of the snowpack, so we are now at 19" rather than the 19.7" at the end of last week's snowfall. 1/2
2/24/26 11:50am Update:
Plenty of rain coming down on that fresh snow but we don't have any flooding concerns at this time. To monitor real-time conditions across the state, check out the wonderful resources from the NWS California Nevada River Forecast Center!

*The other two being December 1970 (113") and April 1982 (118.5") with digitized records beginning in 1970.
2/20/26 8:35 am Update:
The #snow has stopped but not before giving us another 18.5" (47 cm) in the last day. That brings our 5-day total to 111" (281.5 cm), the third snowiest 5-day period on record at the lab*.
Calm conditions for the next several days but a warmer storm moves in mid-week.
The forecast for this week has been spot-on!
2/19/26 8:45 am Update - the atmosphere is clearly showing off:
1-day ❄️: 25.6"
2-day ❄️: 54.9"
4-day ❄️: 92.5"
And in case you thought we were done… another 8–16" expected TODAY. At this point, the snowpack is basically building an extension onto the lab.
Send snacks. Or a shovel. Or both.

2/18/26 8:45 am Update:
1-day ❄️: 29.3" (74.5 cm)
2-day ❄️: 57.5" (146 cm)
3-day❄️ (storm total): 66.9" (170 cm)
We have flurries and calm conditions currently but snowfall rates will pick up this afternoon and evening bringing another 2-3 feet by Friday morning.
#CAwx #CAwater
2/17/26 8:55am Update:
It. Is. Dumping. We had 28.1" (71.5 cm) of #snow in the last day and we're expecting another 2-3 feet by tomorrow night.
Anecdotally, the combination of low visibility, intense snowfall, and high winds have created the worst conditions since Feb 2023!
#weather #water
2/16/26 8:35am Update:
Our storm has begun and we have 9.4" (24 cm) of #snow so far with plenty more on the way!
Moderate snowfall is continuing with snow-to-liquid ratios of ~12:1 - lighter and fluffier snow than we normally get! Wind and snow rates will pick up this afternoon.

*Typo in the email. Don't travel late MONDAY, not Sunday
2/15/26 10:05 am:
The biggest storm of the season will start tonight! Check out the forecast and expected impacts in the most recent edition of our email forecast here 👇

🚨 WEBSITE DOWN 🚨
The company that hosts our data is having a problem with their servers and our website is down as a result. The website will come back up once they're able to resolve the issue.
2/11/26 9:25 am Update:
We had 3.3" (8.5 cm) of #snow at the 8 am measurement. Expectedly, the storm came in warm with rain and then switched to snow last night. We expect another 1-2" today.
A larger storm is poised to come through next week, potentially with feet of snow.

Psst... pssst... the forecast is getting better... ❄️❄️❄️

2/4/26 9am Update:
Model ensembles are showing a shift to wet conditions beginning Monday and continuing for most of next week.
We're still too far out to nail down #snow amounts but we will post updates on expected conditions as we draw nearer to the forecast window.
#CAwx #weather
1/28/26 10am Update:
We had 2.8" (7 cm) of #snow overnight, which breaks our nearly 3 week dry spell.
Unfortunately, it looks like this is all we'll get for at least the next 7-10 days. Following recent melt, we are now at 54% of median snowpack and 68% of snowfall to-date.
#CAwx #CAwater
1/26/26 10:35 am Update:
#snow is in the forecast! It's not a ton, only 2-4" on Tuesday night/early Wednesday but it should be enough to momentarily pause the dry conditions. We haven't had snow since January 8th (18 days) and this is definitely a welcome change!

1-day ❄️: 20.7" (52.5 cm)
2-day ❄️: 35.0" (89 cm)
7-day ❄️: 40.9" (104 cm)
With 20.6" of #snow in the last day, we are now at our median snowfall for the 2026 water year! This most recent snowfall puts us on track for the year.

1/4/26 9:20am Update:
1-day ❄️: 14.4" (36.5 cm)

Good morning! Sorry for our website woes, we have a new site that we're excited to launch but have had some issues with Berkeley's IT making the transition. It has been started but no one is in office to finish it, likely until the new year. We'll keep you updated.
