10/11/2025 9:15am Update: Models continue to shift as we move closer to our forecasted #snow for the early half of this week. Currently, model guidance suggests 12-16" of accumulation at our lab Mon-Weds and we'll update as we get closer and outlooks change. #CAwx #CAwater

👀 Is it happening? It might be happening. We'll be keeping an eye on the model runs but early next week is looking pretty good... ❄️❄️❄️ #Snow #CAwx

10/2/25 10:25am No snow yet but plenty of rain over the last 24 hours, which is a great start to the 2026 water year that began yesterday. These early rain storms help prime our soil and keep it moist meaning less water from our snow has to do that job later. #CAwx #CAwater

2/2 Each dot on this map is a lightning strike ranked by the Fire Neural Network on its potential to start a fire. Red is more likely and blue is less likely. This information can be used by fire crews in the area to identify potential risk areas following storms.

How many lightning strikes have we had around Donner Summit and the Lake Tahoe Basin since Saturday? 1500 - each with its own strength and location characteristics involving drought, fuel loads, and recent meteorological conditions. 1/2

We are looking for a company vehicle with 4x4 or AWD that we can use to get to our field sites. We don't have the biggest budget, so we're working on alternatives to buying new. The vehicle doesn't need to be a newer model or even in great condition. 1/2 Bad AI pic for attention

Todays office: the @UCB_CSSL The site is home to one of several new sensors that’ll give firefighters a leg up when lightning storms come through. You’ll see the story soon on @kcranews!

The Snow Lab is hiring! We're hiring a Research Scientist to evaluate snowpack mass and energy balance response to precipitation enhancement using the Weather Research and Forecasting Hydrological (WRF-Hydro) and iSnobal models. Details here 👇 https://t.co/Alb0S3nzr0

What do we do in the summer? @RobMayeda has some great info on a project that we're doing with the Fire Neural Network to respond to lightning ignition fires faster! #CAwx #Fire #FNN

From snow lab to lightning lab? Even though it's Summer, things are still busy up at Central Sierra Snow Lab, as the team continuous the rollout of lightning detection sensors with to pinpoint strikes more likely generate wildfires @nbcbayarea @UCB_CSSL 7/15/2025

Ah yes, summertime. Long hours of sunlight, days at the lake, and... SNOW?! Yes, snow. Currently at the lab we have a mix of #snow and #graupel coming down. Nothing says summer serenity like a blanket of white! #CAwx #Weather

Looking for something to do on your Saturday? Come visit us at Legacy Day at Donner Memorial State Park! We'd love to chat with you and load you up with stickers!

The project, called the California Cold Content Initiative (3CI), aims to increase water forecast capabilities.

The @techreview just released an article that discusses our project to create a system of sensors to measure California's snowpack temperature. Similar work from our partners @DRIScience and @USDA_NRCS is also discussed. Check it out here https://t.co/4YVlfOD0rb

5/13/25 9:45am Update: A fresh blanket of white covers the lab study site after we received 5.9" (15 cm) of late spring #snow in the last day. Other than some flurries today, there's no snow in the forecast, so this could be our last snowfall of the season. #CAwx #CAwater

5/12/25 3:30pm Update: It's not over yet! We've been getting snow all day and it has led to some wonderful spring conditions ❄️❄️❄️

Yesterday we held our final winter and snowpack briefing of the season that corresponded to the final snow survey in #California. Overall, another great season with statewide snowpack reaching average, which makes three years in a row. Check it out here: https://t.co/QNbYJdu9xb

2/2 Snow water equivalent (SWE) is the amount of water that can be obtained by melting snow while accumulation is the depth of newly fallen snow over a season that can differ in density and, therefore, doesn't always have the same water content.
