Monsoon moisture should continue to flow into Southern California through Friday, theNational Weather Service says, drying slightly for the Labor Day weekend and perhaps more significantly next week.

More dramatic effects of the moisture pulse could be seen over mountains and deserts farther inland Tuesday, with rain and thunderstorms possible in the afternoon and evening – and with a similar forecast for Thursday with arrival of more monsoon moisture from the southeast.

Orange County is looking at partly cloudy skies Tuesday with highs around 90 inland, 75 to 80 on the coast.

Wednesday should be mostly sunny and 91 inland, 78 on the coast, as the potential for rain and thunderstorms backs off a bit for the mountains and deserts.

On Thursday, forecasters say, low-pressure air moving alongside high pressure over the central and southern plains should help steer the next pulse of monsoon moisture into the region.

Orange County could see highs of 91 to 96 for inland areas, 77 to 82 on the coast, and once more under partly cloudy skies.

Friday and Saturday should remain partly cloudy as inland highs ease back to 90 Friday, 84 to 89 Saturday.

On the coast it will be 77 Friday, 74 Saturday.

Sunday will start with partly cloudy skies, then turn mostly sunny; inland temperatures will ease a bit further into the 83 to 88 range, while the coast will see little change at 73.

And the forecast for Labor Day is similar: partly cloudy skies in the morning, mostly sunny in the afternoon, and highs of 84 inland and 72 at the beach
