Discussion

... Looking at satellite this early afternoon, our cloud cover has dissipated as temperatures warm throughout the day. Today`s main weather message is lingering chances for showers and thunderstorms, although most indications point to activity well beyond our borders. Currently, there is a 5-10% chance of thunderstorms over the mountains with best chance to see any developed storm over the Shasta County NW Mountains during the afternoon. Main hazards with any developed storm will be lightning, gusty winds, and brief heavy rain showers.

Looking beyond today, we go into a period of cooler and drier weather into early next week with afternoon highs in the 80s to low 90s and daily afternoon onshore breezy weather. Another round of overcast clouds across the Delta and Valley is expected with a 45-70% chance of occurrence for ceilings less than 2000 feet. Afternoon humidity conditions trend drier before settling in the 30-50% range across the Valley, outside a pocket of drier conditions over the northern Sacramento Valley.
