Forecast Discussion:

While the area didn't receive a ton of rain yesterday and last night, it was enough to saturate the ground surfaces and air which brought some areas of fog this morning. Additionally, the PM10 levels have dropped significantly which is good considering it will be a while before the next rain event (at least a week). Drier and warmer conditions this weekend as high pressure builds into the area with afternoon highs reaching the low 70s on Sunday! Some high clouds will move into the area later on Sunday and last into Monday as a weak trough approaches from the west and eventually moves through on Tuesday. Unfortunately no rain is expected with this system. A system is projected to develop over the Rockies for the middle of next week and may bring a backdoor cold front to area later in the week. We'll have to keep tabs on the possibility for strong easterly winds next Thursday/Friday and its effect on the Hidden Valley PM10 monitor. In the meantime, enjoy the low dust risks and beautiful weather. Check back on Tuesday for an updated air quality forecast.
