...COMFORTABLE APRIL...

COMFORTABLE DAYS RETURNED TO WESTERN NEW YORK IN APRIL FOLLOWING
ANOTHER HARSH WINTER AND SLOW START TO SPRING. THE MONTH HAD THREE
WEATHER REGIMES...WITH EACH LASTING ABOUT 10 DAYS. THE FIRST 10 DAYS
IN APRIL SAW DAILY SWINGS IN TEMPERATURES AS WINTER`S COLD AND LATE
SEASON SNOW BATTLED WITH THE STRONGER APRIL SUN ANGLE AND WARMTH OF
SPRING. THE MIDDLE OF THE MONTH WAS PLEASANT WITH ABOVE NORMAL
WARMTH AND A FEW APRIL SHOWERS. THE END OF THE MONTH FINISHED ON THE
COOL SIDE WITH SCATTERED LIGHT SHOWERS AND SPRINKLES.

THE AVERAGE TEMPERATURE THIS MONTH WAS 47.6F DEGREES...WHICH IS OVER
A DEGREE ABOVE NORMAL...AND FIRST ABOVE NORMAL MONTH SINCE LAST
DECEMBER. THE FIRST 80 DEGREE READING OF THE YEAR OCCURRED ON THE
13TH WITH A READING OF 84F DEGREES...WHICH IS ABOUT TWO AND A HALF
WEEKS EARLIER THAN NORMAL. THERE WERE NO RECORDS ESTABLISHED THIS
MONTH.

PRECIPITATION FOR THE MONTH SUMMED TO 2.70 INCHES WHICH IS JUST SHY
OF NORMAL. ALONG A WARM FRONT NEARLY AN INCH OF PRECIPITATION FELL
ACROSS THE GENESEE VALLEY ON MONDAY APRIL 20TH. THERE WAS A NORMAL
AMOUNT OF DAYS (13 DAYS) WITH PRECIPITATION THIS MONTH. THERE WAS
MEASURABLE SNOWFALL ON THE 24TH-25TH WHICH TALLIED HALF AN INCH.

A WARM FRONT LIFTED ACROSS NEW YORK STATE ON THE 2ND AND BROUGHT THE
FIRST TASTE OF SPRING TO THE REGION. GUSTY SOUTHERLY WINDS BROUGHT
TEMPERATURES INTO THE UPPER 60S AND LOWER 70S ACROSS WESTERN NEW
YORK. FOLLOWING A COLD FRONT PASSAGE ON THE 3RD...A MINOR SNOW
ACCUMULATION OCCURRED ACROSS THE REGION ON SATURDAY APRIL 4TH. THE
PATTERN FOR THE NEXT WEEK FEATURED EARLY SPRING TEMPERATURE
FLUCTUATIONS THAT CUMULATED WITH A STRONG COLD FRONT ON THE 10TH
THAT BROUGHT STRONG...DAMAGING WIND GUSTS ACROSS WESTERN NEW YORK.
FOR MID MONTH A DOMINATING RIDGE OF HIGH PRESSURE REACHED WESTERN
NEW YORK FOR THE MIDDLE PORTION OF THE MONTH. THERE WERE SUN-FILLED
DAYS THAT ALLOWED THE GRASS TO GREEN AND EARLY SPRING FLOWERS TO
APPEAR. RAIN SHOWERS WERE LIGHT AND TENDED TO FALL DURING THE LATER
EVENING AND OVERNIGHT HOURS. THE LAST THIRD OF THE MONTH WAS
DOMINATED BY A SLOW MOVING CUT OFF LOW THAT BROUGHT UNSEASONABLY
COOL TEMPERATURES AND CLOUDY DAYS TO WESTERN NEW YORK. THIS SYSTEM
BROUGHT SEVERAL INCHES OF SNOW TO THE HILLS OF SOUTHWESTERN NEW YORK
STATE ON THURSDAY THE 23RD...AND EVEN A FEW TENTHS OF AN INCH OF
SNOW ACROSS THE GENESEE VALLEY. THIS SNOW FALLING THROUGH THE EARLY
MORNING HOURS SNARLED THE MORNING COMMUTE. LATE APRIL`S WARMTH
RETURNED FOR THE FINAL FEW DAYS OF THE MONTH.

IN ALL A TYPICAL APRIL THAT WAS WELL WELCOMED FOLLOWING THREE MONTHS
OF WELL BELOW NORMAL TEMPERATURES.
