Summer heat to last all week across Southern California
Summer is coming in hot on the last day of spring.
Temperatures across Southern California are forecast to be near or in the 90s all week, with today being the hottest day of the week. Tuesday just happens to be the first day of summer, and even though temperatures might let up a little bit that day, the high heat is forecast throughout the week across the region.
And it won't be a dry heat — forecasters say there's a possibility of tropical moisture reaching Los Angeles County by Wednesday. As a result, Southern Californians could see cumulus buildups in the mountains and feel stickier than usual.
Monsoon-like weather can also mean dry lightning. Forecasting models show an increasing threat of dry lightning across a portion of drought-parched California, which raises the possibility of destructive wildfires.
...arrive across southern 2/3 of CA by mid-week. This will bring chance of at least mountain/desert t-storms, & perhaps even chance of lightning over lower elevations south of I-80. Details still fuzzy, but could be some dry-ish lightning over peak drought region. #CAwx #CAfire pic.twitter.com/bEiDFSKgOe
