THEN BY THE END OF THE MONTH ANOTHER DEEP STORM SYSTEM BROUGHT A
MULTI-DAY RAIN EVENT TO WESTERN NEW YORK.

CONSECUTIVE BLUE SKY DAYS. A MOISTURE LADEN COLD FRONT CROSSED
WESTERN NEW YORK ON THE 7TH AND 8TH WITH A WIDESPREAD SOAKING
RAINFALL. HOWEVER, THE DRY GROUND SOAKED UP MUCH OF THIS RAINFALL,
LEAVING THE DEEP GROUND DRY AND CONTINUING THE SEVERE DROUGHT ACROSS
THE REGION. ANOTHER STALLING COLD FRONT ON THE 11TH ALLOWED FOR
LIGHTER PRECIPITATION AMOUNTS ACROSS WESTERN NEW YORK. ON THE 11TH

BUFFALO AREA ON THE 18TH, WHILE A SURFACE WAVE ALONG A COLD FRONT
BROUGHT ADDITIONAL RAINFALL THE 19TH AND 20TH. AFTER A BRIEF BREAK
IN THE PRECIPITATION, A CANADIAN SOURCED STORM SYSTEM BROUGHT A FEW
RAIN SHOWERS ON THE 21ST, FOLLOWED BY LAKE EFFECT RAIN THE 22ND
THROUGH THE 23RD. HEAVY RAINFALL ON THE 22ND SET A NEW PRECIPITATION
RECORD FOR BUFFALO, AND ACROSS THE NORTHERN SUBURBS OF BUFFALO
GRAUPEL MIXED IN WITH THE COLD BANDS OF LAKE EFFECT RAIN. COOL AIR
REIGNED SUPREME THE FINAL 10 DAYS OF THE MONTH WITH SEVERAL DAYS OF
NORTHEAST FLOW AND FROSTY MORNINGS. ONE FINAL STORM SYSTEM ON THE
30TH AND 31ST OF THE MONTH BROUGHT ADDITIONAL RAIN SHOWERS AND GUSTY

DURING THE EARLY EVENING HOURS.

MONTH DOWN TO 57°F BY THE END OF OCTOBER. THIS 57°F READING IS 3
