COUNTRY'S 156th ANNIVERSARY. >> WE GOT A FEW HIGH CLOUDS OUT THERE TO START OUT THIS SUNDAY MORNING. THEY'RE NOT STICKING AROUND LONG AND I'M GOING TO PLAY THIS FORWARD QUICKLY TO SHOW YOU WHAT TODAY LOOKS LIKE. CLEAR, SUNNY SKIES AND A LOT OF HEAT AND VERY LITTLE MARINE LAYER. YOU CAN SEE AS WE GET TOWARDS THE LATE MORNING, THERE'S A LITTLE BIT OF IT HANGING OUT ALONG THE COAST BUT NOT ENOUGH TO HELP US YET. AS WE POINTED OUT AT THE TOP OF THE NEWSCAST, WHILE TODAY MAY NOT BE AS HOT AS YESTERDAY WAS, A COUPLE OF DEGREES COOLER, IT'S STILL HOT ENOUGH. AND WE STILL HAVE A HEAT ADVISORY, SO BEFORE I GET TO THAT, JUST PICK OUT YOUR PART OF THE BAY ON HERE. THERE'S THAT 99 FOR LIVERMORE. 97 IN CONCORD. WE'RE GOING TO GO TO 90 IN SANTA ROSA AND IT WILL BE 90 IN FREMONT TODAY AND 91 IN SAN JOSE. SO WHEN WE CHANGE OUR PERSPECTIVE AND SEE WHERE THE NATIONAL WEATHER SERVICE STILL HAS HEAT ADVISORIES IN PLACE, IT'S ALL THOSE INLAND VALLEYS. EVEN SAN JOSE IS INCLUDED IN THIS. SO GO EASY ON YOURSELF OUT THERE AND IT STAYS IN EFFECT UNTIL 11:00 TONIGHT. WHAT DOES GOING EASY ON YOURSELF MEAN? FIND THE SHADE, STAY HYDRATED, AND KNOW THE SYMPTOMS IF YOU HAVE GOT TO BE OUTSIDE AND/OR IF YOU KNOW, IT'S THE FIRST ONE -- FIRST REAL SIGNIFICANT OF THE SUMMER, IF ANYBODY MAYBE HASN'T PREPARED FOR THIS ENOUGH AND YOU ARE STILL GOING ABOUT YOUR, YOU KNOW, WEEKEND ROUTINE, JUST KNOW HOW TO RECOGNIZE THE SYMPTOMS BETWEEN IF IT'S JUST HEAT EXHAUSTION OR HEATSTROKE AND THE SYMPTOMS ON THE LEFT ARE FOR HEAT EXHAUSTION. MAYBE YOU GET A BIT FAINT AND MAYBE YOU GET A BIT DIZZY AND YOU ARE REALLY EXCESSIVELY SWEATING. THOSE ARE SIGNS AND YOU CAN STILL KIND OF CUT THIS OFF AT THE PASS. BECAUSE IF YOU GET INTO THESE SYMPTOMS OVER HERE NOW, YOU ARE EXPERIENCING HEATSTROKE. IF IT'S A THROBBING HEADACHE, IF YOU HAVE STOPPED SWEATING, IT'S AT THAT POINT IT'S TIME TO CALL 911 BECAUSE HEATSTROKE IS VERY SERIOUS. OKAY. HERE'S THE COMPARISON BETWEEN TODAY AND FOURTH OF JULY. I'M GOING TO SWITCH THE MAP NOW AND WATCH THE COLORS CHANGE. FAR MORE AGREEABLE TONES. MUCH BETTER NUMBERS AND THESE ARE AVERAGE FOR THIS TIME OF YEAR, GOING TO 81 IN THOSE. TOP OUT AT 85 IN CONCORD? THAT'S WHERE WE SHOULD BE. KEEP IN MIND I'M TALKING ABOUT TUESDAY HERE. LET'S NOT FORGET TODAY IS NOT AVERAGE. TODAY IS GOING TO BE PRETTY HOT. AND JUST TO KIND OF REVIEW IT WITH THE BIG PRETTY FLAG ON HERE, JUST TO LOOK ACROSS THE BAY IN GENERAL, YOU CAN SEE HOW THAT TREND TAKES US AND WE'RE GOING TO BE EVEN COOLER ONCE WE GET PAST TUESDAY INTO WEDNESDAY AS THE TREND CONTINUES. ALL RIGHT, IN THE 7 DAY FORECAST, WE CAN ALREADY SEE HOW THINGS PLAY OUT HERE FROM A COOLING TREND. SAN FRANCISCO AND OAKLAND, MAYBE YOU DIDN'T NECESSARILY NEED ONE ALL THAT MUCH. IT WAS RELATIVELY WARM IN OAKLAND BUT YOU'RE ONLY LIKE FIVE DEGREES ABOVE AVERAGE FOR SATURDAY AND SUNDAY, BUT HERE'S WHERE WE REALLY NEEDED THE RELIEF AND WHY WE HAVE A FIRST ALERT WEATHER DAY HERE. NORTH BAY VALLEYS AT 90 DEGREES AND SAN JOSE YOUR NUMBER AT 91 AND WE'VE BEEN OVER THAT ALREADY. BUT IF YOU LOOK AT THE COOLDOWN, LOOK AT THE TEMPERATURES GOING DOWN TO THE LOW TO MID-70s AND THE FINAL LOOK HERE FOR THE MICROCLIMATES FOR THE INLAND EAST BAY, THOSE NUMBERS ARE GOING DOWN TO THE MID-70s BY THE TIME WE GET TO FRIDAY. OF COURSE THE BEACHES ARE WHERE IT'S AT TODAY. GOING TO BE NEAR 70 DEGREES TODAY. GOING TO BE A POPULAR PLACE. MAKE SURE YOU TAKE TRAFFIC INTO ACCOUNT ON A DAY LIKE THIS. BECAUSE WE HAD SOME REPORTS ON THAT YESTERDAY AND YOU CAN SEE IT'S A VERY POPULAR IDEA. BUT MAYBE YOU MIGHT WANT TO CONSIDER. THAT'S THE FIRST ALERT FORECAST FOR NOW.
