A wide range of weather is expected in San Diego County by the end of the week, starting with a burst of rain Thursday night and a transition into Santa Ana conditions by Sunday, forecasters said.

A large storm system forming over California is expected to bring some rainfall to San Diego County by Thursday night, NBC 7 Meteorologist Sheena Parveen said.

"Do expect rain, it'll start maybe an hour before or after midnight and maybe earlier on in the northwest corner of the county than the southeast corner," said NBC 7's meteorologist Dagmar Midcap.

The storm will be slow to develop, and whatever rain reaches San Diego County will be mild compared to the dumping regions to our north can expect. Light, scattered showers may continue overnight and into Friday morning.

No more than a half-inch of rain is expected in the county. Coastal areas can expect about .1 inch and mountain ranges could see more than a quarter-inch.

There was lightning all over the county Thursday night, but nowhere were the storm's effects captured to greater effect, though, than up in Encinitas, where a fifth-grader seemed to summon a strike at will.

San Diego can also expect some snow early Friday evening for elevations at 5,500 feet. Several inches of snow are expected mainly above 7,000 feet, the National Weather Service said.

Along with some rain, winds will ramp up in San Diego County and peak overnight Thursday. The strongest gusts were expected in the mountains and deserts with peaks reaching up to 65 mph.

A wind advisory was issued for Thursday at 5 p.m. until Friday at 5 p.m. for the mountains and inland valleys. Breezy conditions were expected along the coast and inland valleys as well.

The weekend is expected to be warm and sunny, Parveen said. Another weather shift will come on Sunday as Santa Ana winds develop, bringing with it another warm-up.
