May 20-24 Slightly cooler temperatures Friday but expect a slight warm up as a high pressure begins to build off the West Coast bringing sunny, warmer, dry and breezy conditions to our area this weekend. Expect Inland daytime highs in the mid 70s to mid 80s while Coastal areas can expect daytime highs in the mid 60s to upper 70s. Overnight low for Inland areas will be in the upper upper 40s while along the Coast overnight lows will be mid to upper 40s to low 50s. AQIs are expected to be in the GOOD category for PM2.5 and OZONE. AQIs may briefly reach MODERATE for PM10 due to elevated winds in the Salinas Valley and Hollister.
