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. THE FIRST WEEK OF APRIL SAW
FREQUENT SNOW SHOWERS, THOUGH THE SNOW RARELY ACCUMULATED OR STUCK
AROUND. THE HEAVIEST SNOW FELL ON APRIL 6 WHEN 2.0 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. HEAVY RAIN MOVED IN ON
THE 16TH WHEN MORE THAN 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 5 OUT OF 6
DAYS TOPPING 60 DEGREES FROM THE 23RD THRU 28TH.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 40.9 DEGREES WHICH WAS 3.4
DEGREES BELOW NORMAL AND THE COLDEST APRIL YET RECORDED IN THE SHORT
23-YEAR HISTORY OF OBSERVATIONS AT THE NATIONAL WEATHER SERVICE
OFFICE IN GRAY. UNTIL THIS YEAR, THE COLDEST APRIL ON RECORD WAS IN
2003 WHEN THE AVERAGE TEMPERATURE WAS 41.1 DEGREES. THE WARMEST WAS
IN 2010 AT 49.0 DEGREES. THE TABLE BELOW LISTS THE WARMEST APRILS
RECORDED AT GRAY.

3     41.9  2007
4     42.0  1997
5     42.4  2016

A TOTAL OF 5.10 INCHES OF PRECIPITATION FELL WHICH WAS 0.72 INCHES
ABOVE NORMAL. THE HEAVIEST FELL ON APRIL 16 WHEN 2.16 INCHES WAS
RECORDED. THE WETTEST APRIL ON RECORD WAS IN 2005 WHEN 10.62 INCHES
WAS RECORDED. THE DRIEST WAS IN 1999 WHEN ONLY 0.35 INCHES FELL.

ALTHOUGH SNOW WAS OBSERVED ON 9 DAYS IN APRIL, ONLY 2.4 INCHES WAS
MEASURED WHICH WAS 2.4 INCHES BELOW NORMAL. SNOWFALL IN APRIL IS
OFTEN VARIABLE. THE SNOWIEST APRIL WAS IN 2007 WHEN 27.2 INCHES
FELL. NO SNOW FELL IN 1999, AND AN ADDITIONAL 3 YEARS OBSERVED ONLY
A TRACE OF SNOW IN APRIL, MOST RECENTLY IN 2009. THUS, ACCUMULATING
SNOW FALLS IN APRIL IN 83 PERCENT OF YEARS.
