Forecast Discussion: Forecast discussion for April 24 to April 29: A cold front will be arriving late tonight bringing with it some well needed rain. The instability from this storm will have a scouring affect which will provide clean air to the region. High pressure will begin to set up immediately following the passage of the front, causing a warming trend through the remainder of the forecast period. The air quality is expected to stay in the GOOD category of the AQI along the coast, however, warming temperatures and stable air in the inland portions of the air basin may cause daytime air quality to climb into the MODERATE category on Monday and Tuesday. Please note, due to the long-term drought CAL FIRE has SUSPENDED OPEN BURNING in the State Responsibility Areas of Monterey and San Benito Counties. During these extremely dry conditions, residents are also cautioned about the high risk of causing a wildfire when using any potential ignition source near dry grass and brush.
