YUMA, Ariz. (KYMA, KECY-TV) - Isolated/spotty showers and thunderstorms is possible this afternoon and evening within our area.

Seeing a few storms toward our north and some spotty showers off to the east, and with any thunderstorm that develops may produce gusty winds, frequent lightning, and brief heavy rainfall.

An Excessive Heat Warning remains in effect on Wednesday and Thursday for portions of Yuma and Imperial Counties, where highs will range 108-116 degrees.

Remember to practice heat safety at all hours of the day.

As a ridge of high pressure sits over the south, it will bring in the heat while stirring monsoonal moisture from the south.

Slight chances for showers and thunderstorms will linger into Wednesday, greater chances will favor our higher elevation and mountain areas.

Increasing moisture from a tropical disturbance off the coast of Mexico will result in much cooler temperatures and better chances for widespread rainfall across the Desert Southwest this weekend.

Take a look at our big drop in our temperatures by the weekend and early next week, and days we could experience rain showers and thunderstorms.

Greatest opportunities for rain is looking Saturday-Monday where precipitation amounts between a half and three quarters of an inch could be possible.
