Possible major storm for SF, Valley and Sierra next week
-- This from the Sacramento Office forecast's discussion pm 6 March. January and much of February were pretty dry so flooding probably won't be too bad. However, the amount of snow predicted would likely close the Sierra passes, e.g. Donner, Echo at least periodically during the week.--------------- [NationalWeatherService] Ensemble guidance and cluster analysis continue to exhibit high confidence in an active weather pattern returning to the forecast over the extended forecast period with multiple weather systems moving through Monday [10 March] and again Tuesday through Thursday [13 March] bringing along rain, wind and mountain snow impacts to interior northern California. Here is a look at some 72 hour probabilities from the National Blend of Models (NBM) ending 5 AM Thursday: Probability of Rain > 1 inch: 55-95% Probability of Rain > 2 inches: 15-30% (Valley), 45-80% (foothills) Probability of Mountain Snow > 48 inches: 40-85% Probability of Mountain Snow > 60 inches (N of I-80): 40-70% Probability of Mountain Snow > 60 inches (S of I-80): 15-45% Probability of Wind Gusts > 40 mph: 50-85% (Valley/Foothills) Probability of Wind Gusts > 55 mph: 45-75% (Foothills/Mountains) Posted by: Lord Garth 2025-03-07 |
