The temperature swings could pose moderate heat risks in lower mountain valleys midweek, while gusty winds in the mountains may create challenging conditions for outdoor activities. Coastal areas may experience reduced visibility due to morning fog, and isolated frost is possible in interior North Coast areas by Sunday morning. The weak cold front could bring light rain or drizzle to parts of the North Coast, but precipitation chances remain low further south. Residents should prepare for fluctuating temperatures and changing weather conditions throughout the week.
