Your SoCal Weather Report For May 4: Wet And Cold And Yes, That Was Thunder You Heard

Many of us woke up to rain this morning, and according to the National Weather Service, there’s a 20% chance of isolated thunderstorms as well. That brings the possibility of small hail and lightning.
The bulk of the storm is moving from the Los Angeles basin into Orange and San Bernardino counties, where half an inch of rain is expected on the coast, along with an inch in the mountains.

The wet weather will likely continue through Friday, said Kristen Lund, a meteorologist with the National Weather Service.
"We’ll expect some lingering showers, especially over the mountains and foothills, through Saturday morning," she said.

About that thunder and lightning
Last year when we also had an unusual spate of thunderstorms, we looked into how often we experience thunder and lightning here in L.A.
Here's what we learned:
Within a 10-mile radius of LAX, the National Oceanic and Atmospheric Administration has recorded a grand total of approximately 1,200 cloud-to-ground lightning flashes over the nearly three decades between 1988 and 2017.
By contrast, in Florida — a lightning hotspot — Orlando sees 14,000 strikes in an average year.
This day in history
On this day in 1950, it was 35 degrees in Santa Ana, the lowest temperature on record for May in that region.
Things to do
All this wet and gloomy weather makes for a perfect indoor excursion. Here are a couple things to do that will keep you dry and entertained:
