... CLOUDY AND WET MONTH ...
CLOUDS WERE ABUNDANT THIS MONTH WITH FULL DAYS OF SUNSHINE LACKING.
THE FIRST AND LAST WEEKS OF THE MONTH WERE QUIET AND WARM, WHILE THE
MIDDLE WEEKS OF THE MONTH FEATURED TWO HIGH END WIND EVENTS, AND
SEVERAL LAKE EFFECT SNOW EVENTS FOR THE ROCHESTER METRO AREA. THE
COMBINATION OF THESE LAKE EFFECT EVENTS AND GENERAL RAINFALL PUSHED
THE PRECIPITATION FOR THE MONTH TO 13TH WETTEST ON RECORD.
THE TEMPERATURE FOR THE MONTH AVERAGED 30.1F. THE MAXIMUM
TEMPERATURE WAS JUST 1.6F DEGREES ABOVE NORMAL, WHILE THE MINIMUM
TEMPERATURE AVERAGED WELL ABOVE NORMAL, COMING IN AT 6.2F DEGREES
ABOVE NORMAL. THE COMBINED DECEMBER AND JANUARY AVERAGE TEMPERATURE
OF 35.0F IS SECOND WARMEST IN 153 YEARS OF RECORD FOR THIS 2-MONTH
STRETCH, AND WARMEST SINCE 1931-32. THERE WERE JUST 8 DAYS THAT
AVERAGED BELOW NORMAL, ALL CONSECUTIVE DURING THE MIDDLE PART OF THE
MONTH. THE 11 DAYS THAT REMAINED AT OR ABOVE FREEZING IS 4TH
GREATEST IN RECORDED HISTORY. DESPITE THE WARM MONTH, THERE WERE NO
TEMPERATURE RECORDS SET.
PRECIPITATION TOTALED 4.18 INCHES FOR THE MONTH, FINISHING TIED FOR
13TH WETTEST ON RECORD. PERSISTENT LAKE EFFECT SNOW MID-MONTH, AND A
SYNOPTIC RAIN EVENT THAT DROPPED OVER AN INCH OF RAIN ON THE 26TH
PRODUCED THE WET MONTH. THE NUMBER OF DAYS (23 DAYS) WITH MEASURABLE
PRECIPITATION WAS 4 DAYS MORE THAN NORMAL (19 DAYS). SNOW TOTALED
25.6 INCHES WHICH IS JUST A COUPLE INCHES SHY OF NORMAL. LIGHT SNOW
THROUGH MUCH OF THE FIRST THREE WEEKS OF THE MONTH, WITH THE
GREATEST DURING THE WEEKEND OF JANUARY 19TH TO 21ST WHEN A FOOT OF
LAKE EFFECT SNOW ACCUMULATED ACROSS MUCH OF THE ROCHESTER METRO AREA
ON A NORTHERLY FLOW OFF LAKE ONTARIO. THE SNOW DEPTH BUILT TO 9
INCHES THIS MONTH WHICH IS AVERAGE.
THE MILD START TO WINTER CONTINUED INTO THE FIRST HALF OF JANUARY
WITH ABOVE NORMAL TEMPERATURES RECORDED THROUGH THE 13TH. THERE WERE
TWO RELATIVELY CLOSE WIND EVENTS THIS MONTH THAT PRODUCED WIDESPREAD
WIND DAMAGE. BOTH EVENTS FEATURED STRONG SOUTHEASTERLY DAMAGING WIND
GUSTS, NOT THE COMMON SOUTHWEST WIND DIRECTION FOR HIGH WIND EVENTS.
THE FIRST EVENT, ON THE 9TH AND 10TH OF THE MONTH WAS FOLLOWED BY
THE SECOND EVENT ON THE 13TH AND 14TH OF THE MONTH. BEHIND A COLD
FRONT ON THE 13TH, THE FOLLOWING 8 DAYS FEATURED BELOW NORMAL
TEMPERATURES. LAKE EFFECT SNOW ON THE 13TH THROUGH THE 15TH
OSCILLATED ACROSS THE BUFFALO METRO AREA, OCCASIONALLY REACHING AS
FAR EAST AS ROCHESTER. AFTER A SYNOPTIC WAVE OF LOW PRESSURE PASSED
ACROSS THE REGION WITH A LIGHT GENERAL SNOWFALL ON THE 16TH, ANOTHER
BAND OF HEAVY LAKE EFFECT SNOW FORMED ACROSS THE BUFFALO SOUTHTOWNS
LATE ON THE 16TH. THIS BAND OF SNOW AGAIN OSCILLATED ACROSS ERIE
COUNTY THROUGH THE 18TH. WHILE THIS BAND OF SNOW AGAIN EXTENDED TO
ABOUT THE ROCHESTER METRO AREA ON A SOUTHWEST FLOW OFF LAKE ERIE, A
NORTH TO NORTHWESTERLY FLOW ACROSS THE OPEN LAKE ONTARIO WATERS ON
THE 19TH THROUGH 21ST BROUGHT DAY-TO-DAY LAKE EFFECT SNOWFALL THAT
ADDED UP TO AROUND A FOOT OF FLUFFY SNOW ACROSS THE NORTHERN GENESEE
VALLEY. WINTER`S BRIEF APPEARANCE ENDED ON THE 24TH WHEN
TEMPERATURES WARMED INTO THE LOWER 40S WITH WIDESPREAD RAINFALL.
THIS RIPENED THE SNOWPACK, SUCH THAT THE INCH OF RAINFALL ON THE
26TH MELTED THE SNOWPACK PRODUCING POOR DRAINAGE FLOODING. WHILE ICE
JAMS OCCURRED ON AREA CREEKS THEIR IMPACTS WERE MANAGEABLE DUE TO
THIN ICE THICKNESS. SEVERAL CREEKS AND RIVERS ROSE TO NEAR OR BEYOND
BANKFULL DURING THIS WARM STRETCH, INCLUDING THE BLACK CREEK AND
IRONDEQUOIT CREEK. A LITTLE LIGHT RAIN AND SNOW ENDED THE MONTH WITH
LITTLE IMPACT. THE FINAL DAY FEATURED A SUNNY START, A RARE PERIOD
OF SUNSHINE FOR THE MONTH.
WINDS AVERAGED 1.3 MPH BELOW NORMAL. THE STRONGEST GUST WAS DURING
THE FIRST MAJOR WIND EVENT ON THE 10TH, WITH THIS GUST FROM THE WEST
AT 56 MPH DURING THE EARLY AFTERNOON.
IN ALL A FEW WEEKS OF IMPACTFUL WEATHER MID-MONTH, OTHERWISE MILD,
WET AND CLOUDY.
