The Bay Area is experiencing a significant drop in temperatures, leading to a cold snap that has resulted in frost warnings across the region. Temperatures dipped to as low as 30°F in some areas, prompting Bay Area residents to prepare for possible impacts on outdoor activities and gardening. The National Weather Service issued a freeze warning for the Bay Area, predicting coldest temperatures early Tuesday, with low temperatures in many regions including the North Bay. Meanwhile, parts of Arizona are also bracing for a similar cold front. Phoenix can expect lows around 38°F while higher elevations in northern Arizona may see temperatures diving to 20°F. The threat of frost could jeopardize sensitive plants and crops, as many farmers are rushing to protect their crops to avoid significant losses. The weather pattern is attributed to an Arctic air mass moving into the region, which meteorologists are closely monitoring. Local authorities and weather agencies are advising residents to dress warmly and take necessary precautions to safeguard their health and property during this cold weather.
