Forecast Discussion: [View the ADEQ Hourly Forecast for Yuma]
Did you step outside this Friday morning to enjoy some cooler air? The low this morning in Yuma was 71 degrees, which is the coolest we have seen since June 24th!

These cool temperatures are the result of a trough of low pressure moving through the state. Latest satellite imagery shows the tail end of this system moving through Arizona this morning. As the system continues pushing eastward, expecting light northerly winds and cooler temperatures today with highs this afternoon in the mid-90s.

A weak ridge of high pressure will build back into the area late Saturday into Sunday, allowing temperatures to rise slightly. This pattern will be short-lived as all eyes shift to our next weather disturbance that is forecast to move into the region late Sunday into Monday.

A trough of low pressure is forecast to once again move through the state late Sunday into Monday as remnant tropical moisture from Lorena also moves into the state. This set-up could lead to decent rain chances for the state, but the key will be timing and exact placement of the moisture. If the trough stays a bit north of Arizona, there won't be much energy to work with to produce showers and thunderstorms. If the moisture shifts further east or stays south, obviously rain chances will be much lower. Bottom line, there are many moving parts with this next storm system, and slight deviations can drastically change the forecast. For Yuma, going with a slight chance of rain late Sunday into Monday with rain totals generally staying below 0.25".

With more active weather, forecasting air quality to remain in the Good AQI category through the weekend into the first part of next week.

Have a great weekend!
