Santee is expected to shift from extreme October heat into a cooler, wetter weekend, according to the National Weather Service forecast for the city.

The local forecast calls for a chance of showers after 5 p.m. Saturday, with rain showers likely Saturday night and Sunday. The weather service said Saturday could still reach the mid-80s before cooler conditions settle in Sunday.

The National Weather Service San Diego office said rainfall chances increase Saturday night, with widespread rain expected Sunday. Forecasters also said periods of moderate to locally heavy rain are possible Sunday, especially in the mountains and deserts, and that gusty winds are expected around the region.

For Santee residents, the timing means outdoor plans could be affected late Saturday through Sunday. It also comes as the city and county have been urging residents to prepare for wet weather after a prolonged dry, hot stretch.
