Forecast Discussion:
The set-up on this Friday morning includes an area of low pressure dropping south/southeast through the Great Basin (this is the system that was off the coast of Canada yesterday) and high pressure along the West Coast of the United States. The low will continue moving southward down the front side of the high and into Arizona later today before bottoming out just south of Arizona on Sunday.This storm system will spread clouds across the region late today through Sunday, increase easterly winds on Saturday afternoon/evening into the 15-25mph range, and bring a slight chance of rain to the area Saturday into Sunday. Not expecting much in the way of rainfall with this system as it will be relatively moisture-starved due to its overland trajectory, but we could see 0.01-0.15 inches in the more favored areas.
The system will quickly move east late Sunday into Monday as the tail end of a weak and dry kicker system drops into the state Monday. Tuesday into the middle part of next week, the large ridge off the coast will move eastward and center itself over the state. This pattern will mean mainly light winds, mostly clear skies, and warming temperatures.
As for air quality, forecasting ozone, PM-10 and PM-2.5 to be in the Good AQI category through the forecast period.
Have a great weekend!
