Forecast Discussion:

The 80s were back this weekend, and they are here to stay through at least Thursday. The reason for these warm temperatures is high pressure, which is currently elongated along a line from about Houston back up toward Las Vegas. At the same time, an area of low pressure is sitting just north of the spur of Baja, directly underneath the ridge.

For the most part, this pattern will not change much through the week, so expect continued above-average high temperatures (in the low to mid-80s), just a few passing high clouds from time to time, and mainly light winds.

There may be a slight change by Friday into the weekend, as a low-pressure system develops between California and Hawaii by the middle of the week and moves into the Southwestern United States this weekend. This pattern shift may be enough to slightly weaken the high, allowing temperatures to drop into the upper 70s, which is still above average for this time of year.

As for air quality, right now, we are forecasting ozone, PM-10, and PM-2.5 to be in the Good AQI category through the forecast period. We may see some spikes in PM-10 and PM-2.5 during the early morning and evening hours as inversions develop; however, the strong surface heating during the day will help to allow both pollutants to mix quickly after sunrise allowing concentrations to lower.
