Forecast Discussion: April 19 to April 24, 2018 – Chilly with low clouds and early morning chance of precip for Thursday. Dry and warmer conditions move in by Friday and into the weekend. Mild conditions early next week with a low pressure system and possible chance of another rain event mid to late next week. Although the district AQI monitors are predicted to be mostly in the GOOD category for both PM2.5 and PM10 throughout the week colder night temps may bring San Lorenzo Valley monitors into the MODERATE category between rain events. |
