This brought from 1 to 6 inches of rain, with totals of 2 to nearly 4 feet of heavy snow above 4500 feet. Gusty southerly wind gusts of 25 to 50 mph in the Valley, 40 to 60 mph in the mountains and foothills were recorded. Roads were reported to be flooded, as well as covered with mud and rocks in some mountain and foothill areas. Numerous downed trees were reported during this time, along with mountain highway closures and chain restrictions, with roadway flooding in the Central Valley.

NWS Sacramento, CA wrote its last area forecast discussion before the first event at Feb 12, 12:43 PM PST, 9 hours 17 minutes earlier.
Area Forecast Discussion National Weather Service Sacramento CA 1243 PM PST Wed Feb 12 2025 .SYNOPSIS... A winter storm will bring moderate to heavy rain and snow and gusty winds tonight through Friday. Brief break in precipitation on Saturday and then weak system brings light precipitation chances over higher terrain later in the weekend. && .DISCUSSION... Latest GOES-West visible satellite imagery illustrates increasing cloud cover across interior northern California on this Wednesday afternoon. Below freezing low temperatures from this morning have since warmed to the 40s to 50s in the Valley and foothills, and 30s to 40s in the mountains, valid at 1230 PM PST. Warmer low temperatures are expected the next several nights. A winter storm will arrive tonight, bringing along moderate to heavy rain and snow, gusty winds and isolated thunderstorms. Precipitation will first arrive later this evening and spread inland through the day Thursday before tapering off Friday. Thursday is projected to be the most impactful day with the heaviest rain and snow, best thunderstorm chances, and strongest winds. Gusty southerly winds will develop tonight and persist through Friday morning before decreasing through the day. Strongest winds are expected on Thursday where the NBM shows a 55 to 85 percent probability of wind gusts of 40 mph in the Valley and Delta. The Wind Advisory remains in effect for these areas from 10 PM tonight through 10 AM Friday to address potential impacts such as loose objects blowing around, downed trees/branches, power outages and difficult driving conditions. Gusty winds are also expected up in the mountains, around 45 to 65 mph, and when combined with snow, will create hazardous white out conditions at times. Snow amounts have not changed too much for the mountains, however a few inches of snow are now in the forecast for the lower elevations of Shasta and Tehama counties down to around 500 feet. High resolution guidance, ensemble meteograms and EC Shift-of-Tails all indicate the potential for some snow down to Redding late tonight through Thursday morning as a cold pocket of air lingers before snow levels rise, although the NBM does not have snow levels that low. Given the low confidence but potentially impactful situation, the Winter Storm Warning has been extended in area down in elevation to include the Burney Basin and northern Sacramento Valley above 500 feet, and includes the city of Redding. 2 to 6 inches of snow are possible between 500 and 2000 feet from 10 PM tonight through 10 AM Thursday. The risk for snow in Redding will end late-morning as snow levels rise through the day. The rest of the snow forecast and Winter Storm Warnings above 2000 feet in Coastal/Northern mountains and above 4500 feet in the Sierra/southern Cascades remain unchanged. Moderate to heavy rain with this storm will bring impacts to the lower elevations tonight through Friday. Expect slick roads, minor flooding, mud /rock slides and rises on area waterways. There is also a 10-20% probability of thunderstorm development on Thursday, with the best chances in the Delta, Valley, foothills and portions of the Sierra. A Flood Watch remains in effect below the snow line from 10 PM tonight through 10 PM Friday to address these conditions. Drier weather is in the forecast Friday night through Saturday after the late week storm moves out of the area and we see a break in precipitation. Weak northerly flow returns to the area with cooler morning low temperatures on Saturday (although not quite as cold as the past few days). && .EXTENDED DISCUSSION (Sunday THROUGH Wednesday)... Ensemble guidance and cluster analysis indicate a weak weather system moving across the Pacific Northwest Saturday night through early Monday. Little to no impacts are expected from this late- weekend system, with just some dustings of snow and light showers mainly over higher terrain and north of Interstate 80. On Monday, as any lingering precipitation tapers off, it appears we can expect a return to drier and slightly warmer weather that continues into Tuesday. There is some uncertainty beyond Tuesday but some guidance shows a weak shortwave passing by to the north that could bring some additional light showers mainly in the mountains mid next week. && .AVIATION... VFR conditions through the daytime hours today, expected to rapidly deteriorate after 03z as a winter storm begins to impact interior NorCal. MVFR conditions through the evening transition to IFR/LIFR as precipitation becomes more widespread overnight. North Sacramento Valley snow levels 500 to 1500 feet overnight rising into the day on Thursday. Some -SN possible into RDD overnight as a result. Sierra snow levels generally 3000 to 4000 feet. Light winds today become predominantly southerly and gusty after 06z. Valley/Delta/foothills gusts 30 to 45 kts, with gusts to 60 kts along the Sierra into Thursday. && .STO WATCHES/WARNINGS/ADVISORIES... Flood Watch from 10 PM PST this evening through Friday evening for Carquinez Strait and Delta-Central Sacramento Valley- Motherlode-Mountains Southwestern Shasta County to Western Colusa County-Northeast Foothills/Sacramento Valley-Northern Sacramento Valley-Shasta Lake Area / Northern Shasta County- Southern Sacramento Valley-West Slope Northern Sierra Nevada- Western Plumas County/Lassen Park.
