Calm Before the Storm: Cloudy Skies and Mild Temps Precede Incoming Winter System

Morning: A Grey Start to the Day

San Diegans waking up this Sunday morning, February 15, 2026, will find themselves under a persistent blanket of clouds. Early morning temperatures are hovering in the mid-50s, with high humidity levels near 89% creating a damp, cool atmosphere across the coastal and inland valleys. While no significant rainfall is expected during the early hours, the grey skies serve as a quiet prelude to a significant shift in the regional weather pattern expected to begin early tomorrow.

Afternoon: Mild and Overcast

As we move into the afternoon, the thick cloud cover will remain, preventing the sun from making much of an appearance. However, temperatures will rise to a mild high of approximately 65°F. Despite the overcast conditions, it remains a relatively calm day for outdoor activities before the weather takes a turn for the worse. Key details for this afternoon include:

• High Temperature: 65°F
• Cloud Cover: 100% overcast
• Chance of Rain: Low (approximately 10-20%)
• Wind: Light southwesterly breezes at 5-10 mph

Evening: Preparing for the Front

By Sunday evening, the atmosphere will begin to feel more unsettled as a cold front approaches from the north. Temperatures are expected to dip back toward a low of 53°F. Humidity will settle around 65%, and a 10-20% chance of isolated sprinkles will persist through the night. While Sunday itself remains dry for most of the county, the evening is the ideal time for residents to secure loose outdoor items and prepare for the incoming wind and rain.

Alerts and Warnings: Major Storm Hits Monday

The National Weather Service has issued several watches and advisories that residents should monitor closely. While today is relatively stable, the region is bracing for a powerful winter system. Current notices include:

• Wind Advisory: A Wind Advisory has been issued for Monday, with south winds of 15 to 25 mph and gusts potentially reaching 40 mph along the coast and inland valleys.
• Winter Storm Watch: High elevation areas in the San Diego County mountains are under a Winter Storm Watch starting Monday, with heavy snow and gusts up to 70 mph forecast.
• Rain Outlook: Monday carries a high probability of rain—up to 90%—with significant accumulation expected through the middle of the week.

Drivers are urged to use extra caution during the Monday morning commute as the first significant bands of rain are expected to make roads slick and visibility poor.
