statement on the upcoming weather pattern change

From the National Weather Service: NORTHERLY FLOW BETWEEN A HIGH PRESSURE SYSTEM OVER THE PACIFIC AND A LOW PRESSURE SYSTEM OVER THE GREAT BASIN WILL BRING BREEZY NORTH WINDS TO NORTHERN CALIFORNIA SATURDAY MORNING. THE STRONGEST WINDS WILL BE OVER THE NORTHERN PORTION OF THE STATE AND WILL LIKELY ELEVATE FIRE DANGER. THE GREAT BASIN LOW IS FORECAST TO MOVE WESTWARD SATURDAY AFTERNOON BRINGING AN END TO THE BREEZY NORTH WINDS AND A MAJOR CHANGE TO THE WEATHER PATTERN. MORE UNSTABLE CONDITIONS WILL BRING A THREAT OF THUNDERSTORMS OVER THE MOUNTAINS OVER THE WEEKEND WITH INCREASED CLOUDS AND COOLER TEMPERATURES ELSEWHERE. IT APPEARS THAT INITIALLY...ANY THUNDERSTORM ACTIVITY MAY ONLY CONTAIN VERY LIGHT RAINFALL WHICH COULD TEMPORARILY INCREASE FIRE DANGER. SLIGHTLY COOLER TEMPERATURES SATURDAY WILL BE FOLLOWED BY STILL COOLER TEMPERATURES ON SUNDAY WITH HIGHS DROPPING TO NEAR NORMAL. THIS WILL BE A SIGNIFICANT CHANGE FROM THE NEAR RECORD HIGH TEMPERATURES EXPERIENCED OVER THE LAST SEVERAL DAYS. ANY MOUNTAIN THUNDERSTORMS SUNDAY SHOULD CONTAIN AT LEAST SOME RAINFALL AS THE ATMOSPHERE BEGINS TO MOISTEN UP. THE UPPER LOW IS EXPECTED TO ROTATE UP A BIGGER SURGE OF MOISTURE ON MONDAY. THIS WILL BRING A THREAT OF SHOWERS OR THUNDERSTORMS TO NEARLY ALL OF NORTHERN CALIFORNIA. AS WITH ANY THUNDERSTORMS...MONDAYS STORMS WILL PRODUCE LIGHTNING...GUSTY WINDS AND THE POTENTIAL FOR HAIL AND BRIEF HEAVY RAIN. MOSTLY CLOUDY SKIES WILL BRING STILL COOLER TEMPERATURES WITH MOST LOCATIONS MONDAY LIKELY TO SEE DAYTIME HIGHS SEVERAL DEGREES BELOW NORMAL. THE UNSETTLED AND COOL WEATHER PATTERN IS EXPECTED TO CONTINUE AT LEAST THROUGH THE MIDDLE OF NEXT WEEK. IF PLANNING OUTDOOR ACTIVITIES OVER THE NEXT SEVERAL DAYS BE PREPARED FOR A SIGNIFICANT WEATHER CHANGE. MUCH COOLER TEMPERATURES ARE LIKELY MOST AREAS WITH THE POTENTIAL FOR RAINFALL AND INCLEMENT WEATHER. CHECK BACK FOR UPDATES REGARDING THIS SPRINGTIME WEATHER SYSTEM.
