Forecast Discussion:

High pressure is shifting eastward this morning into New Mexico as a weak weather system moves into the Western US. This system will eventually form a closed area of low pressure that will be cut off from the storm track. As a result, it will sit and spin off the coast of Baja for the next couple of days.

Just north of the low, high pressure will build back into the Southwest US, which will result in reasonably light north winds and continued above-average high temperatures through at least Monday.

By late Tuesday into Wednesday, things begin to change! A trough of low pressure is forecast to dive down the West Coast of the United States, which will help to draw the cutoff low northward. These two systems are expected to merger together over the desert Southwest. This pattern change will result in rain chances beginning late Tuesday through the day on Thursday for Yuma. This system is also forecast to bring a decent drop in temperatures by the middle to end of next week! Stay tuned, as there are still many details to iron out regarding this storm system.

As for air quality, with light winds in the forecast through the next few days, PM-10 is forecast to be in the upper Good to low Moderate AQI category, with ozone remaining in the Good AQI category.

Have a great weekend!
