particular type of flight. 100 hope flights, that is. it all started, decades ago, with a simple desire to help children in some way. and why not with the thing he knows best. >> now i wanted to help

our microclimate forecast. you can see a beautiful shot here in san francisco. the fog continues to move in right across the bay. it was because of that fog the coastline stayed cool today. but the cooler marine air was not strong enough to knock down our temperatures hereby for the interior. as we head throughout tomorrow, we are anticipating temperatures to start off mostly clear and 53 in san francisco. the peninsula, 57. the south bay at 59. let's take you into the microclimate forecast. temperatures not going to change too much for tomorrow. bottom line, it's going to be warm to hot for a lot of us in the south bay. we have 93 degrees expected in cuperti cupertino, san jose, 92. for the peninsula, we have 67 in pacifica. the main reason why palo alto will not see 90s is because the cool wind at the coastline will remain. that's also why san francisco stays in the 60s. let's take the warpest microclimate in the city, the financial district and 69. for the north bay, the trivalley, we have our hottest temperatures tomorrow in the trivalley. danville expecting 97 degrees and livermore 95. for the east bay, a widespread mix of conditions. oakland, 75. walnut creek, 94. freemont, 92. north bay, napa, 89, mill valley, 83. all of this heat, every single bit of it across the entire valleys, all being driven by this area of high pressure. that stays with us through friday's forecast. there's going to be a key change on friday. we talked about our fire danger increasing the most then. that has everything to do with the wind. what you're going to see here is the winds will it unmore to a dryer direction coming out of the east. any kind of air here for the interior valleys is just continually passing over the land. that's why the humidities will continue to lower and temperatures will begin to increase. so friday, no doubt, the hottest day in the forecast this week. here's what it's going to do to temperatures. the coastline, we're not expecting 80s, but it will be close in san francisco, with 79 degrees. for walnut creek, a very hot 102 degrees. as we take you into your weekend forecast, we're going to see some changes in those temperatures. gradually, we're going to see them drop from 102 in the trivalley on friday, down to 97 on friday. all over the place, bottom line, hot through friday, then 10 to 15 degrees of cooling as we head into the weekend. >> all right, jeff, thanks a lot. we're moving around. talking about rain. coming up, how a melted bucket caused a potentially tockics situation in palo alto. >> a new tool to help you
