And hes hoping his next venture will benefit thousands of lowincome children. Garvin thomas with tonights bay area proud. Janelle, while it was soccer and football jim messimer was best at, his fondest memories are baseball, playing catch with his dad when he was a kid. Its just one part of his past that jim has pulled from for his latest venture helping children build their first block to success, the ability to read. Say i will take turns. I will take turns. Though there have been many a great book written about baseball whats this letter . Reporter books and baseballs perfect. Reporter dont normally mix at school. P. Good job.

Take a look at this video coming into our newsroom. Theres a Flash Flood Warning in San Bernardino and northern los angeles counties. It is intense to say the least. Heavy downpours and severe thunderstorms throughout the day and as we speak. Specifically this is in lancaster which is north of los angeles. Roads as you can see washing away. Were also getting reports of several cars and even homes that have been swallowed by the rushing and muddy waters. You see the bridge overpasses there and all that water just seeping into the land. So far, no word on any injuries. I know janelle, we were talking about this with jeff ranieri of the lightning strikes in the area. Theyve been hit hard in the last day or so. Yeah, its part of that storm system that brought us a few areas of showers over the past 24 hours. The center of low pressure is to the south where were finding the strongest activity at the current moment and the largest problem is how slowly this is moving off toward the east. The slow movement is enhancing these flooding impacts. That video just unbelievable. The ground is so dry. You get a lot of rain in a short amount of time. Theres nowhere for that water to go. And you can see right now on the radar, its right here near lancaster. Where we do have a very, very strong thunderstorm moving off to the northeast. Hail, nearly a half inch in diameter, multiple lightning strikes, and also some extremely gusty winds. It will be a rough next couple of three to four hours for this heavy rainfall continuing. Now lets take you back outside to the Sky Camera Network here at home. Weve had some of that subtropical moisture. The humidity teoday. At least the temperatures were cooler. 79 in the south bay. East bay 78 currently. San francisco at 62. Now, we did have a few spotty showers reported in the east and also the south bay this morning and i still think well hold on to a slight chance of some showers as we head throughout tomorrow. So lets go ahead and take a look at the forecast. Best chance would be in the south bay with 61 degrees. Maybe a few drops in the east bay and 60. For San Francisco, well start with areas of early fog and 58 degrees. So once again, the storm system thats producing flooding in Southern California continues to move off toward the east and the overnight hours. Again, may produce an isolated shower. Overall for fridays forecast, we cant shake the humidity just yet. Well have partly sunny skies and temperatures that will be just about similar to what we experienced for today. Then as we head throughout saturday, we still have the storm system on the way. Its expected to break up before it gets here. A shower chance but mainly to the north, includes maren, napa, also sonoma counties. The rainfall moving into california probably has you thinking about whats ahead for winter. In case you missed our update at the earlier far of this show, we have the latest on what we can expeshlg expect for rainfall. Classic el nino. Drier weather possibly for the Pacific Northwest. Right back into the midwest as well. Lets take you to the microclimate forecast as we head throughout friday. And youll see that fog is coming back into San Francisco. And 65 degrees.
