Forecast Discussion:

It was another warm day yesterday, with a high of 77, which is well above average for this time of year. 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 (mid to upper-70s), 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 low 70s.

As for air quality, things become a bit more tricky. Overnight lows will continue to be on the cold side, with strong inversions setting up each night. As a result, we are forecasting PM-10 and PM-2.5 values to rise as pollutants get trapped close to the ground (below the inversion). On the plus side, the above-average high temperatures in the afternoon allow pollutants to quickly mix out and rise off the ground as the inversion breaks. With this pattern, we are forecasting PM-10 to be in the Good AQI category through Thursday, with PM-2.5 in the Moderate AQI category through the weekend.
