OF IT. >> AND IT WAS A BEAUTIFUL DAY FOR A ST. PATRICK'S DAY EVENT. BUT CHANGES ARE ON THE WAY. LET'S GO OVER TO FIRST ALERT METEOROLOGIST DARREN PECK. >> IT IS LUCKY TO BE A 180 BY THE TIME WE WOULD GET TO NEXT WEEKEND. WE'RE GOING BACK TO RAIN TO GET COLDER AGAIN AND IT IS TOTALLY DIFFERENT FROM THE DAY YOU JUST SPOKE TO AND THAT IS A REVIEW OF THE LAST TWO HOURS. AND THE CITY WAS AT 61 DEGREES. 62 WILL BE AVERAGE. RIGHT ON THE MARK FOR THAT. IF YOU LOOK AT THE VALLEYS, THAT IS WHERE IT IS NOTICEABLE WARMER. AND TOMORROW IS GOING TO GET ABOUT A DEGREE OR TWO WARMER THAN THIS. AND JUST TO SHOW YOU HOW TOMORROW STARTS, I'LL SHOW YOU THIS MORNING. WE'LL GO BACK IN TIME HERE. TAKING A LOOK AT EARLY SUNDAY MORNING IN THE 6:00 HOUR. WE WOKE UP TO MAY GRAY TODAY FOR PARTS OF THE CITY. IT'S GOING TO BE MORE WIDESPREAD TOMORROW. WHEN WE USE THE HIGH RESOLUTION FORECAST TO SEE HOW THIS GOES, YOU CAN ACTUALLY SEE THE VALLEYS HERE. ALL THE CLOUDS KIND OF CONFORMING THROUGH THE PETALUMA GAP UP THERE IN SONOMA COUNTY. NAPA, OF COURSE, YOU CAN SEE THE BULK OF THE DAYS. AND WHEN WE COME IN, YOU CAN TAKE THE DRIVE UP 101 AND MOST OF MARIN. WE WILL WAKE UP TO THE MAY GRAY SKIES TOMORROW MORNING. I THINK THE TRIVALLEY MIGHT AVOID THIS. BY THE TIME WE WOULD GET TO LATE MORNING, THAT'S ALL GONE. WE WILL GO RIGHT BACK TO MORE BLUE SKIES JUST LIKE IT IS NOW WITH THE DAYTIME HIGHS A DEGREE OR TWO ABOVE WHERE THEY ARE TODAY. SO SAN JOSE, YOU'RE GOING TO 76 TOMORROW. MONDAY IS ACTUALLY THE PEAK FOR THIS. IT'S THE WARMEST DAY IN THIS SEVEN-DAY FORECAST. NOT TO SAY TUESDAY AND WEDNESDAY ARE STILL REALLY NICE. THEY ARE. TUESDAY AND WEDNESDAY PRETTY MUCH CARBON COPIES, BUT THEY WILL BE A LITTLE COOLER. THEN BY THE END OF THE WEEK, EVERYTHING CHANGES. SO LET'S GO BACK TO THE FORECAST IMAGERY, AND WE WILL BRING BACK THAT STORY JUST TO SHOW YOU HOW THIS STORM SITTING WAY OUT IN THE PACIFIC FINALLY IS ABLE TO BREAKTHROUGH THIS DOMINATING RIDGE AND BRING US BACK TO WINTER. AND THAT IS PROBABLY A GOOD WAY TO START THINKING ABOUT THIS. SO MANY PEOPLE ARE ENJOYING THIS WEEKEND AS YOU SHOULD. WE ARE GETTING TOWARDS, YOU KNOW, COMING OVER FAST ON THE EQUINOX. IT WILL BE SPRING HERE. AND HOWEVER, THE ATMOSPHERE HAS NOT CAUGHT ON YET. IF WE WATCH THE NEXT STORM, IT WILL FINALLY BREAKTHROUGH THE RIDGE. NOW LOOK WHAT'S SITTING OFF THE COAST ON FRIDAY. AND THIS HAS GOTTEN A LITTLE CLEARER IN TERMS OF THE PICTURES IN THE LONG RANGE MODELS. ALTHOUGH THIS IS FAR FROM ASSURED IN TERMS OF DETAIL AND TIMING. AND THE FACT THAT THEY WILL GET RAIN. GOING INTO FRIDAY THROUGH SUNDAY. WATCH WHAT HAPPENS. YOU'LL SEE HOW THE STORM HAS BEEN PUT TOGETHER WITH A GOOD SUBTROPICAL TAP OF MOISTURE ALMOST LIKE IT'S GOT A WEAK ATMOSPHERIC RIVER, PULLING UP INTO IT. A PRETTY GOOD AREA OF LOW PRESSURE THAT WILL COME DOWN FROM ALASKA. SO IT IS GOING TO HAVE EVERYTHING THAT YOU NEED. YOU WILL HAVE COLD AIR TO WORK WITH AND MOISTURE TO WORK WITH AND THEY WILL DRAG MOST OF THE RAIN LIKELY THROUGH WEDNESDAY INTO SATURDAY. AND WE COULD HAVE ANOTHER SYSTEM THAT WILL COME OUR WAY AFTER THAT. ONCE WE GET INTO NEXT WEEK. WE ARE NOT GOING TO GO THAT FAR DOWN THE ROAD YET. LET'S TAKE A ONE DAY AT A TIME. HERE IS THE MOST LIKELY OUTCOME RIGHT NOW FOR HOW MUCH RAIN WE MIGHT SEE IN THE TIME PERIOD. THIS IS THE MODEL THAT WILL BE BULLISH THAN THE OTHER LONG RANGE FORECAST MODEL. SO THE TOTALS ARE BIG HERE WITH AN INCH AND A HALF FOR SOME PLACES HERE ON THE HIGH SIDE. MORE LIKE A LITTLE OVER AN INCH IN GENERAL. AND IF WE GET THAT MUCH RAIN IN THAT PERIOD OF TIME, WE ARE NOT CONCERNED ABOUT FLOODING. THIS IS NOT A SERIOUSLY IMPACTFUL STORM. BUT IT'S GOING TO BE A NOTICEABLE STORM BECAUSE THEY WILL FEEL LIKE A 180 FOR US AFTER THE INCREDIBLE WEATHER THAT WE ARE HAVING OUT THERE THIS WEEKEND. AND YOU'LL SEE THE RAIN THAT WILL COME BACK HERE ON FRIDAY, BUT WE KEEP THE SCATTERED SHOWERS GOING FOR SATURDAY AND SUNDAY. IT IS STILL GOING TO REMAIN TO BE SEEN HERE. HOW THE TIMING AND THE INTENSITY WILL WORK OUT FOR NEXT WEEKEND. BUT IF YOU'VE BEEN GOING ALONG WITH THIS ALL WINTER LONG, THIS IS HOW MOST STORMS HAVE COME TOGETHER. GIVE US UNTIL ABOUT WEDNESDAY AND THEN WE'RE REALLY GOING TO BE ABLE TO START NAILING DOWN SOME OF THE SPECIFIC DETAILS IN TERMS
