Sacramento's Driest Period - EVER!

It looks like Sacramento will have some rain over the next week. Nevertheless, let us not forget that we are now leaving the driest period ever recorded in Sacramento's recorded history: drier than 2014-15, drier than 1976-77 - DRIEST PERIOD EVER! 

I paraphrased the following from two National Weather Service reports: 
---- 

...ALL-TIME RECORD DRY STREAK ESTABLISHED AT DOWNTOWN SACRAMENTO... 

THE DOWNTOWN SACRAMENTO CLIMATE SITE ESTABLISHED A NEW ALL-TIME RECORD DRY STREAK OF 212 DAYS. THE PREVIOUS RECORD OF 194 DAYS WAS SET FROM MAY 13, 1880 THROUGH NOVEMBER 22, 1880. THE NEW RECORD IS MARCH 19, 2021 THROUGH OCTOBER 17, 2021. 

MEASURABLE RAINFALL IS RAINFALL OF 0.01 INCHES OR GREATER AND DOES NOT INCLUDE TRACE AMOUNTS. DOWNTOWN SACRAMENTO REGISTERED 0.01 INCH ON OCTOBER 17TH. 

DOWNTOWN SACRAMENTO`S PERIOD OF RECORD DATES AS FAR BACK TO 1855. DURING THE EARLY YEARS OF THE PERIOD OF RECORD, THERE WERE LARGE GAPS OF MISSING DAILY PRECIPITATION DATA THROUGH THE MIDDLE 1870S. STARTING IN WATER YEAR 1878, DAILY PRECIPITATION OBSERVATIONS BECAME NEARLY CONTINUOUS WITH MINIMAL MISSING DATA. THE CLIMATE STATION HAS MOVED AROUND THE DOWNTOWN SACRAMENTO AREA OVER THE COURSE OF TIME, AND IS PRESENTLY LOCATED NEAR SACRAMENTO STATE UNIVERSITY SEVERAL MILES EAST OF DOWNTOWN. 
---- 

...DRIEST WATER YEAR ON RECORD FOR REDDING AREA, RED BLUFF, AND SAC EXEC AIRPORT... 

THE 2021 WATER YEAR RAN FROM OCTOBER 1, 2020 THROUGH SEPTEMBER 30, 2021, AND RESULTED IN WELL-BELOW NORMAL PRECIPITATION AMOUNTS ACROSS INTERIOR NORTHERN CALIFORNIA. SEVERAL CLIMATE SITES IN INTERIOR NORTHERN CALIFORNIA OBSERVED ALL-TIME RECORD LOW PRECIPITATION TOTALS OVER THE COURSE OF THE WATER YEAR, INCLUDING REDDING AREA, RED BLUFF, AND SACRAMENTO EXECUTIVE AIRPORT.
