cooler and unsettled the next couple of days

From the National Weather Service: A SPRINGTIME LOW PRESSURE SYSTEM OVER THE REGION WILL BRING UNSTABLE CONDITIONS TO THE AREA OVER THE NEXT SEVERAL DAYS. THE UNSTABLE CONDITIONS WILL BRING A THREAT OF THUNDERSTORMS OVER THE MOUNTAINS AND NORTHERN PART OF THE SACRAMENTO VALLEY TODAY WITH INCREASED CLOUDS AND MUCH COOLER TEMPERATURES ELSEWHERE. DAYTIME HIGHS TODAY WILL DROP AS MUCH AS 10 DEGREES FROM YESTERDAY BRINGING A SIGNIFICANT CHANGE FROM THE NEAR RECORD HIGH TEMPERATURES EXPERIENCED OVER THE LAST SEVERAL DAYS. THE OVERALL ATMOSPHERE WHICH HAS BEEN QUITE DRY OVER THE PAST SEVERAL DAYS SHOULD BEGIN TO MOISTEN UP TODAY AS THE LOW SETS UP OVER THE AREA. THEREFORE ANY MOUNTAIN THUNDERSTORMS SHOULD CONTAIN AT LEAST SOME RAINFALL. THE UPPER LOW IS EXPECTED TO ROTATE A BIGGER SURGE OF MOISTURE OVER THE INTERIOR OF NORTHERLY CALIFORNIA TONIGHT INTO MONDAY WHICH SHOULD HELP TO REDUCE FIRE DANGER EVEN MORE. THERE WILL BE A THREAT OF SHOWERS OR THUNDERSTORMS OVER NEARLY ALL OF NORTHERN CALIFORNIA ON MONDAY AND TUESDAY. AS WITH ANY THUNDERSTORMS...THE STORMS PRODUCED THIS WEEK COULD 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 AND TUESDAY 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 ALTHOUGH RAINFALL CHANCES WILL DECREASE WEDNESDAY AND BEYOND WHILE DAYTIME TEMPERATURES BEGIN TO WARM. . IF PLANNING OUTDOOR ACTIVITIES OVER THE NEXT SEVERAL DAYS BE PREPARED FOR A SIGNIFICANT WEATHER CHANGE. MUCH COOLER TEMPERATURES ARE LIKELY WITH THE POTENTIAL FOR RAINFALL AND INCLEMENT WEATHER. SNOW LEVELS WILL REMAIN HIGH BUT SOME SNOWFALL ACROSS THE HIGHER PEAKS WILL BECOME LIKELY MONDAY AND TUESDAY. CHECK BACK FOR UPDATES REGARDING THIS SPRINGTIME WEATHER SYSTEM. Yesterday's weather was somewhat unusual. A large complex of thunderstorms associated with this low pressure system mentioned in the NWS's statement moved from east to west over the Sierra Nevada into the valley. By the time it reached the valley there was limited moisture, so not much rain fell. However, the winds from the outflow boundary were very strong from the east, gusting to over 40 mph at times yesterday afternoon and evening. We could see more of that type of weather tomorrow and Tuesday. Stay tuned!
