April 7 is a study in contrasts. Not only is it the latest date for a sub-freezing high temperature (1982), it's also the earliest date for a high in the 90s (2010).
The temperature jumped from 46° to 89°, thirty-two degrees above average. (Yesterday's high was 59°.) At the time this was the earliest date for a temperature so warm.
The Yankees played their home opener under sunny skies, but in very chilly conditions. After a morning low of 31°, the game was played with temperatures in the mid-40s. At least skies were sunny.
A warm front moved through just as the Mets' home opener was beginning, and over the course of the afternoon the temperature rose from 47° to 63°.
In the aftermath of yesterday's snowstorm, the morning low was 21°, twenty-one degrees below average and the coldest reading so late in the year since April 1, 1923 (when the temperature dropped to 12°). Today's afternoon high of 30° was the latest date on record for a sub-freezing high.
The last snowfall of the winter fell at around daybreak, a surprise 0.6". It didn't last long, however, as the temperature rebounded into the low 50s under sunny skies. A total of 13.4" of snow fell during the winter, about half the average amount, and the third winter in a row with well below average snowfall.
Four inches of snow fell, the biggest April snowfall in twenty-one years. This brought the season's snowfall total close to 50 inches. And like 1982's snowfall, today's happened on the day of the Yankees' home opener, which was postponed.
The afternoon high hit 92°, an incredibly hot temperature for so early in the season. In fact, it was New York's earliest 90-degree reading on record, besting the previous record from 1991 by one day. This temperature was 34 degrees above average - even in mid-July, today's high would have been five degrees hotter than normal. At 11 PM it was still 80°. The next 90-degree reading wouldn't be for seven weeks, when the high reached 92° on May 26.
Morning sunshine dimmed by mid-day and rain moved in late in the afternoon, but it held off until the Yankees' home opener had ended (they beat the Orioles 4-2). The game was played under overcast skies with temperatures in the chilly low 50s.
Two-and-a-half weeks after a four-day streak with lows of 29°, today was the fourth day in a row with a low of 42°, which was at the seasonal average. Highs during these days were also very similar: 60°-61°-63°-62°, three or four degrees above average.
Today's high of 68° was the mildest reading of the month. This became the first April since 1940 to have no readings in the 70s or warmer. (Since 2000 the average warmest reading in April has been 85°.)
