The Woodbury Fire remained active overnight, with plenty of smoke and the orange glow of the flames visible from parts of the Valley. Smoke will continue moving away from the Valley today; however, with lighter winds expected during the morning hours Saturday and Sunday, some smoke may move into the east and northeast portions of the Valley. Not expecting it to reach any health standards but you may notice some haze and smell smoke.

Water vapor this morning shows a trough moving into the state which will continue breezy conditions and generate enough ventilation to keep ozone values below Health Watch/Advisory criteria.

Saturday, high pressure will move back over the region, resulting in much calmer winds throughout the atmosphere along with sunny skies. This pattern will be the right recipe for ozone production across the Valley, as a result, will issue an Ozone High Pollution Advisory for Saturday.

By later Sunday into Monday, another weak trough will move into the area, increasing breezes and bringing some additional cloud cover to the city, especially on Monday. With a later onset of winds expected Sunday, there will still be time for ozone to accumulate so will issue an Ozone Health Watch for Sunday before lowering values on Monday below any Health Watch or Advisory threshold.

As for temperatures, expecting them to be in the 101-105 degree range through the first part of next week, which is right at or slightly below average for this time of year.

Have a great weekend!
