Forecast Discussion:

Get ready for some weather changes starting later today (Wednesday), with winds and cooler temperatures moving into the forecast. An area of low pressure is sitting about 400 miles off the coast of California as high pressure shifts eastward. As the low continues moving eastward, the region will be sandwiched between these two pressure systems, resulting in gusty westerly winds of 20-30mph this evening. Breezes will be lighter tomorrow as the low moves through, but still expect westerly winds of 10-20mph.

Another system will drop into Arizona from the northwest on Friday into Saturday, which will once again increase westerly winds into the 25-35mph range. This pattern will also allow afternoon high temperatures to drop into the low to mid-80s tomorrow through Saturday. High pressure will build back into the area Sunday through the first part of next week meaning calmer winds and warming temperatures.

As for air quality, the main concern will be PM-10 (dust) due to the strong winds. Expect values to increase this evening and again Friday afternoon with the strongest winds, so both days will have the PM-10 in the Moderate AQI category.

Have a great Wednesday!
