April 2018 Weather Recap - Chilly, Snowy, Rainy

Rainy day in new york

 

Like four of the past five months, April was colder than average.  (February, the mildest on record, was the outlier.)  This was the chilliest April since 1975, 3.5 degrees below average.  Eight days had mean temperatures ten degrees or more colder than average (and half of the month's days were five degrees or more below average).  Just three days had highs of 70°+, the fewest since April 2000.  Two of them were back-to-back: 82° and 77° on 4/13 and 4/14.  Earlier that week the month's coldest temperature, 32°, was posted on consecutive days, on-par with what the coldest reading is during a typical April (33°).  However, the number of days with highs chillier than 50° (nine) and lows in the 30s (sixteen) was well above average (three and five days, respectively). 

 

April was also a wet month, with 5.78" of precipitation measured, making it the third month in a row to receive more than five inches (5.83" fell in February, 5.17" in March).  The last time this occurred was August-October 2011.  More than half of the month's precipitation fell during a rainstorm on 4/15-16 that dropped 3.29", the biggest deluge since April 30, 2014.  Finally, Easter, which fell on 4/1, was sunny and pleasant, with a high of 60°.  However, 5.5" of snow fell the next morning (forcing postponement of the Yankees' home opener).  This was the biggest snowfall in April since 1982.

April 2018 was just one of three Aprils since 1970 to have an average temperature below 50.0 degrees (coming in at 49.5).  Before 1970, however, April temperatures this cool were much more common, with half of the Aprils between 1869 and 1969 being that chilly.  Therefore, when compared to all Aprils, this April ranks as 44th coolest overall.  Finally, March and April 2018 combined were the coldest first two months of meteorological spring since 1984, and the third coldest in the years since 1970.
