I hope you enjoyed these seasonable 0:02 temperatures today because look at the 0:04 colors on the ground. Look at how yes, 0:06 they are red inland but not too deep and 0:08 dark of red. Look at that. By tomorrow, 0:10 you notice a few of those pinks settling 0:12 in our inland areas. Those signify the 0:15 upper 90s that are returning to the 0:17 forecast from our inland communities. 0:19 Mid 90s down into the Santa Clara 0:21 Valley. Low 90s to upper 80s across our 0:23 North Bay communities. And look at San 0:25 Francisco. 81° as our high temperature 0:28 tomorrow. Those of us without air 0:30 conditioning, which is most of us in San 0:32 Francisco, that is going to be extremely 0:34 hot. So, make sure you get your fans 0:36 prepared because it's going to be hot 0:38 tomorrow and it's likely going to stay 0:39 hot through the middle parts of the 0:41 upcoming week. Look at Tuesday. It only 0:43 gets hotter across our Inland East Bay 0:45 communities. Those brighter pinks 0:47 signify those tripledigit high 0:49 temperatures. And right on the cusp of 0:52 that tripledigit mark across those far 0:54 inland East Bay communities like 0:55 Fairfield and Antioch sitting in the 0:56 upper 90s, mid to upper 90s down into 0:59 the Santa Clara Valley, mid to lower 90s 1:01 across our North Bay, upper 70s in 1:03 downtown San Francisco. Another day of 1:06 well above average temperatures and even 1:07 our coastal communities are going to be 1:09 sitting in the mid70s Tuesday afternoon. 1:12 And again, this is going to stick around 1:13 through Wednesday before a big cool down 1:15 heads our way by the time that we step 1:17 out into Thursday. So, let's take a look 1:19 at that big picture pattern because 1:21 right now we are tracking a tropical 1:23 storm. It's all the way down near the 1:26 coast of Mexico. This tropical storm, 1:28 its name is Mario. This moisture is 1:31 actually going to be heading our way by 1:32 the later parts of this upcoming week. 1:34 And that's what's going to be bringing 1:35 us a cool down by the time that we step 1:38 out on Thursday. Look, it's that 1:40 moisture, at least the outskirts of that 1:42 moisture that is going to be moving up 1:44 along the West Coast, bringing a lot 1:45 more cloud coverage and bringing those 1:47 temperatures down by about 10° later 1:50 this
