UNSETTLED WEATHER TO ARRIVE OVER THE WEEKEND

It looks like our sweltering desert heat of the past several days will soon end.

A low pressure system is forming west of San Francisco tonight, and it will strengthen and move into Southern California Saturday and Sunday. This will bring cooler and windy weather back to the deserts the next several days, as well as scattered showers and thunderstorms throughout Southern California. It will be impossible to know exactly where the rain will fall, as the weather will be convective in nature. Showers will pop up in some areas, and may completely miss other areas.

Satellite image as of Friday night shows a weak system off the coast. This system will move southeast and strengthen the next several days.

SATURDAY

By Saturday, the system will move slowly southeast toward Southern California. Strong west-southwest winds will likely buffet the mountains, high deserts and areas along the I-10 corridor. We will also have a strong chance of higher winds along the southern areas of the valley, as winds may have a southwesterly component. Strongest gusts are expected to reach 50 mph, although most areas will probably only see winds 20-30mph. High temps will likely only reach the mid 80's - a far cry from the 105 degree weather of late.

SUNDAY AND MONDAY

Partly cloudy skies with scattered showers or thunderstorms are possible both days. Some areas may not see much of any rainfall, and others may see over 0.50 inch. There is even a very slight chance of a localized heavy thunderstorm with hail and strong winds. High temps will fall to 68-78 both days, and winds may back to the north. Snow levels may fall to 4,000 feet Sunday morning, but will likely rise to 5,500 feet by Monday. A few inches of snow are possible, but many areas will miss out.

TUESDAY - THURSDAY

The storm will move out and skies will clear. Temps will likely approach 90 degrees of more, but are not expected to rise into the 100's.

FRIDAY AND BEYOND

The weather pattern suggests additional low pressures may move south again during this time period. This should keep temperatures at or below normal, with another slight chance of showers possible.
