...A TEMPERATURE ROLLER COASTER FOR JANUARY...

JANUARY STARTED OUT THE SAME WAY THAT DECEMBER ENDED, COLD. ON
JANUARY 2ND, THE BUFFALO METRO AREA SAW ITS FIRST BLIZZARD SINCE
MARCH 2014. TEMPERATURES BEGAN TO WARM TO MUCH ABOVE NORMAL AFTER
THE FIRST WEEK OF JANUARY, WHICH HELPED TO CONTRIBUTE TO ICE JAM
FLOODING THAT OCCURRED IN PORTIONS OF WESTERN NEW YORK. FOLLOWING
THE WARM SPELL, AN ARCTIC AIRMASS AND WIDESPREAD SNOWFALL AFFECTED
THE AREA FOR THE MIDDLE OF THE MONTH. THIS SECOND COLD STRETCH THAT
SPANNED THE MIDDLE OF THE MONTH WAS THEN FOLLOWED BY ANOTHER LONGER
STRETCH OF MOSTLY ABOVE NORMAL TEMPERATURES TO END THE MONTH.

FOR THE FIRST WEEK OF THE MONTH THE AVERAGE TEMPERATURE RANGED
BETWEEN 10 TO 25 DEGREES BELOW NORMAL. THE END OF THIS COLD STRETCH
MARKED 15 CONSECUTIVE DAYS OF BELOW NORMAL TEMPERATURES THAT BEGAN
ON CHRISTMAS EVE. ALL BUT TWO OF THESE DAYS SAW AVERAGE TEMPERATURES
THAT WERE 10 DEGREES OR MORE BELOW NORMAL. DURING THIS STRETCH OF
WELL BELOW NORMAL TEMPERATURES, MOST OF THE CREEKS AND RIVERS FROZE
OVER WITH THICK ICE. AS THE REGION WARMED UP WITH TEMPERATURES WELL
ABOVE NORMAL COMBINED WITH HEAVY RAIN, THE THREAT FOR FLOODING BEGAN
TO UNFOLD ON JANUARY 11TH. A STRONG COLD FRONT MOVED THROUGH THE
AREA DURING THE MORNING AND AFTERNOON ON JANUARY 12TH, HELPING TO
USHER IN ANOTHER COLD AIR MASS THAT BROUGHT TEMPERATURES BELOW
NORMAL ONCE AGAIN. COLDER THAN NORMAL TEMPERATURES AFFECTED WESTERN
NEW YORK FROM THE AFTERNOON ON JANUARY 12TH THROUGH JANUARY 18TH. ON
JANUARY 19TH, THE WESTERN NEW YORK AREA BEGAN A WARMING TREND THAT
WOULD LAST THROUGH THE REST OF THE MONTH, WITH ALL BUT A FEW DAYS
DURING THIS 13 DAY STRETCH AVERAGING ABOVE NORMAL FOR TEMPERATURES.
FOR THE MONTH OF JANUARY, THE AVERAGE TEMPERATURE WAS 24.2 DEGREES
FAHRENHEIT, WHICH IS 0.7 DEGREES BELOW THE NORMAL OF 24.9 DEGREES.
THE COLDEST DAY OF THE MONTH WAS ON JANUARY 6TH, WHEN THE AVERAGE
TEMPERATURE WAS ONLY 1 DEGREE AND THE MAXIMUM TEMPERATURE ONLY
REACHED 4 DEGREES FOR THE DAY. THE WARMEST DAY OF THE MONTH WAS ON
JANUARY 11TH, WHEN THE AVERAGE TEMPERATURE WAS 55 DEGREES FOR THE
DAY AND THE MAXIMUM TEMPERATURE REACHED 61 DEGREES, WHICH SET A NEW
RECORD FOR THE DAY.

ON JANUARY 2ND, A BLIZZARD WARNING WAS ISSUED FOR NORTHERN ERIE
COUNTY, INCLUDING THE CITY OF BUFFALO AND THE BUFFALO AIRPORT. A
LAKE EFFECT SNOW BAND OVER ERIE COUNTY BECAME BETTER ORGANIZED AS IT
MOVED NORTH OVER THE BUFFALO METRO AREA. WINDS INCREASED AND BLOWING
SNOW BECAME THE PRIMARY ISSUE, BUT THAT COMBINED WITH A LIGHT TO
MODERATE SNOWFALL BROUGHT BLIZZARD CONDITIONS TO THE CITY OF BUFFALO
AND THE NORTHTOWNS. THE NEXT SEVERAL DAYS FEATURED QUIETER WEATHER
WITH A FEW DAYS RECEIVING AN INCH OR TWO OF SNOW. ON JANUARY 11TH
AND 12TH, FLOODING DUE TO BOTH ICE JAMS AND HEAVY RAINFALL WERE
REPORTED IN SEVERAL COUNTIES IN WESTERN NEW YORK, INCLUDING ERIE,
CHAUTAUQUA AND CATTARAUGUS COUNTIES. JANUARY 12TH, STARTED OUT WARM
AND RAINY UNTIL A STRONG COLD FRONT MOVED THROUGH THE AREA
TRANSITIONING THE AREA FROM WARM AND RAINY CONDITIONS TO COLD AND
SNOWY CONDITIONS. HEAVY SNOW FELL ACROSS THE REGION AS AN EXPANSIVE
AREA OF LOW PRESSURE MOVED ALONG THE APPALACHIAN MOUNTAINS AND
THROUGH THE NORTHEAST. THE COMBINATION OF RAIN AND SNOW WATER
EQUIVALENT TOTALED TO 1.10 INCHES OF LIQUID PRECIPITATION ON JANUARY
12TH. DURING THIS TIME THE BUFFALO AIRPORT RECEIVED 6.6 INCHES OF
NEW SNOW THROUGH THE MORNING ON JANUARY 13TH. ON JANUARY 17TH, A
WEAK STORM SYSTEM DROPPED 6.3 INCHES OF SNOW AT THE BUFFALO AIRPORT,
WITH THIS HIGHER SNOWFALL AMOUNT PRIMARILY DUE TO A HIGH SNOW RATIO
OF AROUND 55:1, AS ONLY 0.11 INCHES OF SNOW WATER EQUIVALENT WAS
MEASURED WITH THIS SNOW. WARM TEMPERATURES AND RAINFALL THAT
AMOUNTED TO JUST UNDER A HALF INCH TOTAL ON JANUARY 22ND AND 23RD
POSED ANOTHER RISK FOR ICE JAM FLOODING, WITH A FEW OF THE MORE
COMMON AREAS SEEING SOME ISSUES FROM ICE JAMS, BUT NOT TO THE SAME
EXTENT EXPERIENCED EARLIER IN THE MONTH. ON JANUARY 29TH AND 30TH,
AN INVERTED TROUGH ASSOCIATED WITH A COASTAL LOW BROUGHT SNOW TO
MOST OF WESTERN NEW YORK FROM ROCHESTER ON WEST WITH THE BUFFALO
AIRPORT PICKING UP 5.1 INCHES OF SNOW. AT THE BUFFALO AIRPORT, THE
MONTH OF JANUARY 2018 ENDED UP WITH 31.2 INCHES OF SNOW, WHICH IS
5.9 INCHES ABOVE THE NORMAL OF 25.3 INCHES. WITH THE ADDITION OF THE
SNOWFALL FROM JANUARY, THE SEASONAL SNOWFALL TOTAL IS NOW 65.1
INCHES, WHICH IS 3.6 INCHES ABOVE THE NORMAL 61.5 INCHES THE BUFFALO
AIRPORT WOULD HAVE RECEIVED THROUGH THE MONTH OF JANUARY. FOR THE
MONTH OF JANUARY THE TOTAL LIQUID EQUIVALENT PRECIPITATION AT THE
BUFFALO AIRPORT WAS 3.73 INCHES, WHICH IS 0.55 INCHES ABOVE THE
NORMAL OF 3.18 INCHES.

FOR THE BUFFALO AIRPORT IN JANUARY 2018, SEVEN DIFFERENT RECORDS
WERE BROKEN. ON JANUARY 1ST, THE LOW TEMPERATURE WAS -4 DEGREES,
WHICH SET A NEW RECORD LOW TEMPERATURE, BREAKING THE PREVIOUS RECORD
OF 0 SET BACK IN 1970 AND OTHER YEARS. JANUARY 5TH AND 6TH, BOTH SET
RECORD COLDEST MAXIMUM TEMPERATURES WHEN BOTH DAYS ONLY REACHED 4
DEGREES, BREAKING THE OLD RECORDS SET BACK IN 1912 AND OTHER YEARS
OF 9 DEGREES FOR BOTH DAYS. JANUARY 7TH, TIED A RECORD LOW OF -5
DEGREES WHICH WAS ORIGINALLY SET BACK IN 2014. THE ONE AND ONLY
RECORD HIGH TEMPERATURE FOR THE MONTH WAS SET ON JANUARY 11TH, WHEN
THE TEMPERATURE REACHED 61 DEGREES, BREAKING THE OLD RECORD OF 59
DEGREES SET IN 2006 AND OTHER YEARS. ALSO ON JANUARY 11TH, A RECORD
WARM MINIMUM TEMPERATURE WAS SET AS THE LOW TEMPERATURE ONLY DROPPED
TO 48 DEGREES, THUS BREAKING THE PREVIOUS RECORD OF 38 DEGREES SET
IN 1975. ONE RECORD PRECIPITATION EVENT OCCURRED FOR THE MONTH WHEN
THE COMBINATION OF RAIN AND LIQUID WATER EQUIVALENT FROM SNOW
TOTALED 1.10 INCHES ON JANUARY 12TH, WHICH BROKE THE OLD RECORD OF
0.76 INCHES OF PRECIPITATION ON THE SAME DATE IN 2012.

LAKE ERIE WAS 33 DEGREES FAHRENHEIT ON JANUARY 1ST, AND DROPPED DOWN
TO 32 DEGREES ON JANUARY 2ND, WHERE IT REMAINED THROUGH THE REST OF
THE MONTH.

IN ALL, A MOSTLY AVERAGE MONTH OF JANUARY FOR WESTERN NEW YORK.
