Dangerous heat across the area and san fran disco, the temperature is tolerable especially if you are out about the water and the fog did not make its usual appearance. Paul is in the Weather Center explaining how long all of this will last. It will last through the middle of next week and the worst of the heat will be tomorrow but when it heats up we have to worry about the fire danger and that is the amount of moisture in the air compared to the temperature with a relative humidity and we look out for the spots with a relative humidity is dipped down into the teens and that is where it is in santa rosa and fairfield, concord, and livermore. These will be in similar territory tomorrow if not lower. We will have light wind for most of the day and check out the future cast wind gusts and these are the gusts and not even the sustained wind and this is light for the bay area around five or 10 mph which it picks up a little in the afternoon but if we can keep those wind gusts below 25 mph means sustained wind will be below 15 Miles Per Hour and it helps with the fire danger. It will be as hot as tomorrow and it takes a spark so make sure you are staying fire aware and right now we see some cloud cover overhead coming from way down to our south and will not drop rain or slow down the warm up. 77 downtown and that is 4 degrees cooler than where we topped out this afternoon and 83 in oakland and we have plenty of 90s and 94 in san jose and santa rosa and 98 in concord and 101 and livermore and i showed you at the top of the hour it is 103 and fairfield. We will see it floating up from the south as we head through the rest of tonight and into the morning and the future cast tomorrow shows there out of her head and that acts like a blt and kes temperatures from dropping so we warmer than normal start and gives us a higher jumping off point for temperatures to be hotter tomorrow. We will see the fog and low cloud cover and the clouds away up in the atmosphere so they will filter the sunshine rather than block it and we will see those through midafternoon and that batch of clouds slides up to the north and maybe for the second half of the weekend another batch but not a big impact on temperatures with plenty of heat in store for us for the next few days. Temperatures are warm for this time of year and the warmest spot to be below 74 the lows and by the morning it will mainly be farther inland in the east bay right around 60 in the city and a lot of low to mid 60s and even the cool spots down below 60 so here is the heat for tomorrow. Brace yourselves for 81 in the city and close to 90 degrees and oak and, well into the 90s around the south bay and close to 100 for Santa Clara Valley and a record 98 is a and around 100 for the north bay and the hotspots further east especially east of the diablo range approaching 110 from fairfield toward antioch and brent wood and 105 for much of the trivalley and just find some air conditioning and take a break for the heat of the day and the air quality will be a concern as well and tomorrow is spare the air day and everybody has moderate airquality and the shading here and unhealthy for i that and it is a stagnant air mass without the breeze. Temperatures back up slightly saturday and sunday but still well into the 90s and the numbers for inland temperatures are not the hotspots but we talk about those being the average so within 5 degrees in either side is where you will top out in the vicinity and we are talking highs into the 80s tomorrow backing up a little bit saturday and sunday but warmer than normal temperatures with more triple digit heat possible by the middle of next week. I will have another hour by 53. Look at tomorrows lets get back to the breaking story that we are following down in southern california.
