The greatest chances will be in the mtns and deserts Wed, but we can't rule out some showers and storms in the valleys and at the coast too.

We're starting to fine tune the forecast for the monsoon showers and storms mid-week ⛈️ Monsoon-like weather can increase concerns for flash flooding and mudslides in recent burn scar areas, however, these likely won’t be a factor during this week’s precipitation, Moede said. “Some of the rain that falls will evaporate before it reaches the ground (in lower elevation areas),” Moede said. In the Inland Empire, residents living further north and east around the San Bernardino County mountains will have the best chance at experiencing rainfall, Moede said. There will be between a 20 and 40 percent chance of precipitation across much of Los Angeles County during a 24-hour period ending on Wednesday night, he said. Not only does this coincide with the first day of summer on Tuesday, June 21, but also with the traditional start of monsoon season.Īreas could start seeing rain and lightning as soon as Tuesday night, according to David Gomberg, meteorologist with the NWS.

The increase in atmospheric moisture comes from the Gulf of Mexico to the east and the Gulf of California to the south, Moede said. Seasonably high temperatures will likely persist inland, but cloud cover could potentially knock high temperatures Wednesday down by a few degrees, Moede said. But rainfall totals aren’t expected to be significant, with mountain areas only optimistically forecasted to receive between one-tenth to one-third of an inch of rain, according to Mark Moede, meteorologist with the National Weather Service.
