...MILD JANUARY WITH FEW INTERRUPTIONS...

JANUARY 2017 WILL BE REMEMBERED FOR ITS COMPLACENCY AS ONLY BRIEF
PERIODS OF TRUE WINTER WEATHER OCCURRED. OVERALL TEMPERATURES WERE
WELL ABOVE NORMAL, AND SNOWFALL WAS LACKING. A PERSISTENT WARM AND
MOIST AIRMASS MID-MONTH BROUGHT SEVERAL DAYS OF FOG AND LOW CLOUDS.

THE AVERAGE TEMPERATURE OF 31.0F WAS JUST OVER SIX DEGREES ABOVE
NORMAL, AND PLACED THIS JANUARY AS TIED FOR THE 18TH WARMEST JANUARY
ON RECORD. OF THE 31 DAYS IN THE MONTH, 24 FINISHED ABOVE NORMAL.
THOUGH A VERY MILD MONTH, THERE WERE NO DAILY RECORDS SET. THE
WARMEST DAY WAS THE 21ST WHEN TEMPERATURES SOARED TO 60F ON A MOSTLY
SUNNY SATURDAY AFTERNOON. THIS WAS THE FIRST TIME WE REACHED 60F IN
JANUARY SINCE 2013. THERE WERE 12 DAYS THIS MONTH THAT REMAINED AT
OR ABOVE FREEZING. ONLY 1880 (13 DAYS) AND 1932 (19 DAYS) HAD MORE.
IN FACT, OF THESE 12 DAYS THERE WERE 7 DAYS IN A ROW THAT REMAINED
AT OR ABOVE FREEZING...A FEAT THAT ONLY JANUARY 1995 BEAT WITH 9
STRAIGHT DAYS AT OR ABOVE FREEZING.

PRECIPITATION FOR THE MONTH WAS ABOUT A QUARTER OF AN INCH BELOW
NORMAL, WITH 2.92 INCHES RECORED AS THE MONTHLY TOTAL. SNOWFALL WAS
MUCH BELOW NORMAL, WITH EXACTLY 11.0 INCHES MEASURED THE ENTIRE
MONTH. THIS PLACES JANUARY AS TIED FOR THE 27TH LEAST SNOWIEST MONTH
ON RECORD. HALF THE SNOW THIS MONTH FELL IN ONE EVENT, THIS A LAKE
EFFECT SNOW BAND THAT PASSED OVER THE BUFFALO METRO AREA WITH 5 TO 6
INCHES OF SNOW FALLING ON THE 28TH. PRECIPITATION WAS EVENLY SPREAD
THROUGH THE MONTH AND THERE WERE NO MAJOR RAIN EVENTS AROUND THE
METRO BUFFALO AREA, THOUGH HEAVY RAIN ACROSS THE SOUTHERN TIER ON
THE 12TH CAUSED SIGNIFICANT FLOODING.

JANUARY OPENED THE NEW YEAR QUIET WITH TEMPERATURES RISING TO ABOVE
FREEZING. A WARM FRONT LIFTED ACROSS THE REGION ON THE 3RD,
SPREADING RAIN ACROSS THE REGION...BUT WITH MINOR FLOODING. A COLD
FRONT SWEPT ACROSS THE REGION DURING THE EARLY MORNING HOURS OF THE
4TH, SENDING THE REGION INTO ITS ONLY PROLONGED COLD SPELL THIS
MONTH, AND GENERATING LAKE EFFECT SNOW EAST OF THE LAKES. LAKE
EFFECT SNOW FLEW EAST OF THE LAKES FROM THE 4TH THROUGH THE 8TH,
WHICH BROUGHT SNOWFALL ACCUMULATION ACROSS THE CHAUTAUQUA RIDGE, AND
THE BOSTON HILLS TO 3 FEET. AFTER 5 DAYS WITH BELOW NORMAL AIR
TEMPERATURES, A WARM FRONT LIFTED TOWARDS THE REGION. INITIALLY A
WINTRY MIX OF SNOW, THEN SLEET AND FREEZING RAIN FELL ACROSS WESTERN
NEW YORK ON THE 10TH AND 11TH. A WAVE OF LOW PRESSURE PRODUCE
WIDESPREAD RAIN ON THE 12TH, WITH AN INCH TO AN INCH AND A HALF
FALLING ACROSS THE SOUTHERN TIER AND TOWARDS THE LOWER GENESEE
VALLEY...PRODUCING FLOODING OF BOTH RIVERS, AND AREA-WIDE. FROM THE
17TH TO THE 23RD AIR TEMPERATURES REMAINED ABOVE FREEZING. THERE WAS
A RAIN EVENT ON THE 17TH THAT PRODUCED A HALF TO ONE INCH OF
RAINFALL ACROSS THE REGION, THOUGH WITH MUCH OF THE SNOW MELTED FROM
AN EARLIER RAIN EVENT, FLOODING WAS MINIMAL. THE WARMER
TEMPERATURES, AND AT TIMES NORTHEAST WINDS PRODUCED A PERIOD OF LOW
CLOUDS AND STRATUS. CLOUDS AND VISIBILITIES TENDED TO BE LOWEST FROM
THE EVENING, THROUGH THE OVERNIGHT AND INTO THE MORNING HOURS OF THE
20TH THROUGH THE 23RD. THERE WAS A BREAK IN THE CLOUDS ON THE 21ST
AND THIS ALLOWED FOR TEMPERATURES TO SPIKE TOWARDS 60F...THE WARMEST
DAY THIS MONTH. TRANQUIL CONDITIONS STARTED THE 4TH WEEK OF THE
MONTH BUT A MARGINALLY COLD AIRMASS BROUGHT THE SECOND SIGNIFICANT
LAKE EFFECT SNOW EVENT TO THE REGION, DUMPING UPWARDS TO A FOOT AND
A HALF OF SNOW ACROSS THE SOUTHERN TIER AND BOSTON HILLS. AT THE
BUFFALO AIRPORT, THIS LAKE EFFECT SNOWBAND BROUGHT HALF THE MONTHS
SNOWFALL ON THE 28TH. A CLIPPER ON THE 31ST DROPPED ANOTHER INCH OR
SO OF SNOW ACROSS THE BUFFALO AREA, WITH SEVERAL ACCIDENTS DURING
THE MORNING COMMUTE.

LAKE ERIE REMAINED OPENED THROUGH THE MONTH, WITH JUST TWO DAYS, THE
7TH AND 8TH BRIEFLY REACHING 32F. WINDS WERE LIGHTER THAN DECEMBER,
AND FINISHED JANUARY AT 11.1 MPH, WHICH IS ABOUT A MILE AND A HALF
BELOW NORMAL. THERE WERE TWO HIGH WIND EVENTS THIS MONTH, THE FIRST
ON THE 4TH THAT BROUGHT SEVERAL TREES DOWN ACROSS THE BUFFALO METRO
AREA, AND A SECOND ON THE MORNING HOURS OF THE 11TH...WHICH MEASURED
A PEAK WIND SPEED OF 60 MPH AT THE AIRPORT.

IN ALL A MILD MONTH, LACKING THE DEEP SNOWPACK USUALLY FOUND DURING
JANUARY.
