A distant plume of moisture associated with Tropical Storm Juliette will make it feel more sticky over the next couple of days around Los Angeles.
Thursday will be a very warm day as highs top 90 degrees across much of the L.A. Basin away from the coast. Downtown Los Angeles has not reached the 90 degree-mark since July 1.
By Friday and Saturday, the humidity will be more noticeable than it's been in recent days due to the increase in moisture.
As the moisture associated with Juliette moves out of the area by the Labor Day weekend, the humidity will not be quite as high. Temperatures in and around Los Angeles will also not be quite as high, topping out closer to 80 rather than 90.
While the L.A. Basin will likely stay dry right through the Labor Day weekend, there will be the threat for spotty showers and drenching thunderstorms in the mountains east of the basin on Thursday and Friday. While the thunderstorms will not be widespread, they will have the potential to produce localized flash flooding due to the amount of moisture in the atmosphere.
This is the second time this week that tropical moisture has invaded Southern California. Moisture around Tropical Storm Ivo brought flash flooding to portions of northern Los Angeles County. Over 2 inches of rain fell in a little over an hour in some locations. Similar rainfall rates are possible with the storms Thursday and Friday.
Even in these areas where there will be a few thunderstorms, the Labor Day weekend should turn out dry.
