Northern California forecast: Wildfire smoke impacts air quality as temperatures stay warm (2024)

YOURSELF AND MAKE THOSE GUMMIES YOURSELF. YEAH, YEAH. BE WONDERFUL. YOU KNOW, ENFORCE IN TERMS OF THE FORECAST THIS WEEKEND, THE GOOD NEWS IS YOU’RE HEADING OUT THERE TO SOILBORNE FARMS. IT IS GOING TO BE A LITTLE COOLER, TEMPERATURES STEADILY DROPPING AS WE GO INTO THE WEEKEND. RIGHT NOW I’M TAKING A LIVE LOOK IN DOWNTOWN SACRAMENTO. AND WHAT YOU SEE WITH THAT POP OF COLOR ON THE HORIZON, UNFORTUNATELY, IS AN ELEVATED LAYER OF WILDFIRE SMOKE. SO WE DO HAVE SOME AREAS WHERE THAT SMOKE IS A BIT MORE CONCENTRATED. AS WE KICK OFF YOUR FRIDAY, I’LL SHOW YOU THAT VIEW IN JUST A MOMENT. RIGHT NOW, WHAT YOU NEED TO KNOW SACRAMENTO AIR QUALITY IS GOOD TO MODERATE AROUND THE COUNTY, SO IF YOU’RE TRYING TO GET OUTSIDE FOR A WORKOUT OR JUST WALKING THE DOG THIS MORNING BEFORE YOU HEAD TO THE OFFICE, YOU SHOULD BE IN GOOD SHAPE. UNLESS YOU ARE UNUSUALLY SENSITIVE TO SMOKE. 64, IN STOCKTON, 70 RIGHT NOW. MODESTO GOOD MORNING, LAKE TAHOE. CHECKING IN AT 48. AND RIGHT NOW THE AIR QUALITY LOOKING MODERATE CURRENTLY AROUND THE SIERRA. I WANT TO TALK ABOUT HUMIDITY. AND THIS IS LOOKING AT THE RELATIVE HUMIDITY AROUND THE REGION. YOU’VE HEARD THE FIREFIGHTERS TALKING IN THEIR DISCUSSION ON THOSE FIRE LINES, NOT ONLY FROM THE CROSIER FIRE BUT UP TO THE PARK FIRE AS WELL. NOW WE HAVE THE CANYON FIRE THAT’S BURNING IN TUOLUMNE COUNTY. THESE HUMIDITIES ARE UP QUITE A BIT COMPARED TO WHERE THEY’VE BEEN IN PREVIOUS MORNINGS, WHERE THEY’VE BEEN TALKING TEENS. FOR EXAMPLE, AUBURN’S AT 31%, PLACERVILLE 22%, AND WE’RE INTO THE UPPER 70S RIGHT NOW IN TERMS OF RELATIVE HUMIDITY AROUND SACRAMENTO SMOKE FORECAST. LET’S GO THROUGH THIS PRETTY QUICKLY HERE. AS YOU’LL NOTICE THAT WE DO HAVE A COUPLE OF AREAS LIKE GRASS VALLEY UP IN THROUGH NEVADA CITY. I WOULDN’T BE SURPRISED IF YOU CAN SMELL WILDFIRE SMOKE THIS MORNING AND AROUND PLACERVILLE AND THEN UP TOWARDS AREAS AS YOU GET INTO DIAMOND SPRINGS, SHINGLE SPRINGS NEIGHBORHOODS, AND EVEN UP TOWARDS TAHOE. IT’S A VERY THIN, ELEVATED LAYER, BUT WATCH WHERE THE SMOKE IS GOING TO TRAVEL. THIS IS LUNCHTIME. STILL SEEING A THIN AREA OF SMOKE AROUND NEVADA CITY AND THEN JUST EAST OF PLACERVILLE AND THEN WATCH THAT PLUME FROM THE CROSIER FIRE START TO NAVIGATE AGAIN OVER THE TRUCKEE AND TAHOE BASIN, WHERE WE COULD SEE SOME OF THAT WILDFIRE SMOKE IMPACT TODAY. NOT AN IMPACT DAY DUE TO THE HEAT. WE’RE LOOKING AT HIGHS PUSHING IN MID TO UPPER 90S AROUND THE VALLEY. WE’LL GET INTO THE MID TO UPPER 90S AS WELL WITH THOSE SMOKY SKIES IN THE FOOTHILLS TO START, BUT CLEARING LATER IN THE DAY AND THEN SMOKE COULD MOVE INTO THE SIERRA, PUSHING THOSE TEMPERATURES WHILE OUR TEMPERATURES WILL BE IN THE MID 80S IN THE MOUNTAINS, HIGH PRESSURE. THE BIG FAIR WEATHER FEATURE. IT’S SHOWING SIGNS OF WEAKENING AS THIS SYSTEM PREPS TO MOVE INTO THE AREA BY SUNDAY, AS IT DOES SO, IT INCREASES THAT ONSHORE FLOW AND THAT IS GOING TO HELP TO BRING OUR TEMPERATURES DOWN EVENTUALLY, ESPECIALLY NEXT WEEK. SO WE’RE LOOKING AT UPPER 90S HANGING ON THROUGH THE START OF TH
