THE SPRING-LIKE WARMTH THAT FINALLY ARRIVED AT THE END OF MARCH MADE
A SWIFT DEPARTURE ONCE APRIL CAME AROUND. SEVERAL BACK TO BACK
TROUGHS OF LOW PRESSURE BROUGHT COLD AIR IN FROM CANADA, WITH THE
APRIL SUN TRIGGERING AFTERNOON SHOWERS. SOME OF THESE SHOWERS FELL
IN THE FORM OF SNOW, THOUGH THE SNOW RARELY ACCUMULATED OR STUCK
AROUND. THE HEAVIEST SNOW FELL ON APRIL 6 WHEN 0.6 INCHES WAS
MEASURED. AFTER A BRIEF WARM UP BROUGHT 60 DEGREE WARMTH, MORE COLD
AIR POURED IN FOR THE MIDDLE OF THE MONTH. THE COLDEST DAY WAS APRIL
15 WHEN THE TEMPERATURE WAS BELOW FREEZING ALL DAY. SLEET AND
FREEZING RAIN FELL MOST OF THE DAY, LEAVING AN ICY COATING THAT IS
QUITE UNCOMMON FOR THIS LATE IN THE SEASON. THE HIGH TEMPERATURE OF
32 ON APRIL 15 WAS THE LATEST DATE ON RECORD THAT THE HIGH
TEMPERATURE DID NOT WARM ABOVE FREEZING. HEAVY RAIN MOVED IN ON THE
16TH WHEN NEARLY 2 INCHES OF RAIN FELL WITH TEMPERATURES WARMING UP
JUST A BIT, BUT STAYING BELOW NORMAL. WARMER, SPRING-LIKE WEATHER
FINALLY ARRIVED AGAIN BY THE END OF APRIL, WITH 6 OUT OF 7 DAYS
TOPPING 60 DEGREES FROM THE 22ND THRU 28TH, INCLUDING A FEW THAT
REACHED 70.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 41.6 DEGREES WHICH WAS 3.5
DEGREES BELOW NORMAL AND THE COLDEST APRIL SINCE 2003. THE COLDEST
APRIL ON RECORD WAS IN 1874 WHEN THE AVERAGE TEMPERATURE WAS 37.0
DEGREES. THE WARMEST WAS IN 1941 AT 51.4 DEGREES.

A TOTAL OF 4.30 INCHES OF PRECIPITATION FELL WHICH WAS 0.89 INCHES
ABOVE NORMAL. THE HEAVIEST FELL ON APRIL 16 WHEN 1.80 INCHES WAS
RECORDED. THE WETTEST APRIL ON RECORD WAS IN 1904 WHEN 7.44 INCHES
WAS RECORDED. THE DRIEST WAS IN 1941 WHEN ONLY 0.42 INCHES FELL.

A TOTAL OF 1.7 INCHES OF SNOW FELL WHICH WAS 1.1 INCHES BELOW
NORMAL. THE HEAVIEST FELL ON APRIL 15 AND 16 WHEN 1.1 INCHES OF SNOW
AND SLEET WAS RECORDED. SNOWFALL IN APRIL IS OFTEN VARIABLE. THE
SNOWIEST APRIL WAS IN 1874 WHEN 35.0 INCHES FELL. THERE HAVE BEEN 10
YEARS THAT HAD NO SNOW IN APRIL, INCLUDING MOST RECENTLY IN 2012. AN
ADDITIONAL 36 YEARS OBSERVED ONLY A TRACE OF SNOW IN APRIL, MOST
RECENTLY IN 2010. THUS, ACCUMULATING SNOW FALLS IN APRIL IN 69
PERCENT OF YEARS.

THERE WERE NO DAILY RECORDS SET OR TIED IN APRIL 2018.
