Temperatures on Independence day will be below seasonal averages as a trough of low pressure continues to stay over California.
The beaches will be in the low to upper 60s with cloudy conditions. The big question has been whether or not afternoon and evening clearing is a possibility. Models indicate there will be some clearing but clouds will hang along the coast through the day. However, this should not impact fireworks shows at the beaches.
The coastal valleys will be cloudy Wednesday morning and warm up to the mid-70s. Models show lingering clouds throughout the afternoon. The inland valleys will be slightly warmer ranging from the mid-70s to upper 80s, however, cloudy conditions will clear up by the late morning.
Winds are also picking up Wednesday to a 15-20 mile per hour range making for a breezy afternoon and evening.
Wednesday is the last day of cooler temperatures in the week. On Thursday daytime highs will start to increase and by Friday triple digits are in the forecast for interior valleys and low to upper 90s for the coastal valleys. As a result, an excessive heat watch will remain in place from San Luis Obispo County to Southern California through Sunday.
