Forecast warned of heavy rain, mountain snow and travel impacts for Fresno County

The National Weather Service forecast for the Fresno area issued on Dec. 26, 2025 called for continued unsettled conditions across Fresno County, with an 80% chance of showers and potential thunderstorms through the weekend. Forecasters emphasized the primary risks as heavy rainfall in the valley and significant mountain snowfall at elevations above about 5,000 feet, conditions that could bring localized flooding and travel disruptions.

The forecast identified school and traffic impacts among the most immediate concerns for residents. Heavy valley rain can reduce visibility on major commuting routes and increase morning and evening congestion, while mountain snow can slow or close routes used by truckers and recreational travelers heading into the Sierra. The forecast specifically advised motorists and residents to expect continued heavy mountain snowfall and valley rainfall with potential for localized flooding and travel disruptions.

In addition to the core threats, the forecast office included two low probability hazards. Forecasters placed the chance of damaging winds at less than 5% and the chance of a tornado at under 2%. Both threats were described as atypical for the event but were included to reflect the full risk envelope the forecast team assessed.

For Fresno County, the combination of high probability rain and mountain snow has practical implications for public services and the local economy. School districts and public transit providers were placed on alert for possible schedule changes, and freight and agricultural transport that rely on valley highways may face delays. Residents with travel plans into the higher Sierra should anticipate heavier snowfall at elevations above about 5,000 feet and plan accordingly.
