Since 1980, the average date of the first reading of 80° or warmer is April 21 (a month later than the average date of the first reading of 70°+). This is about a week earlier than 1900-1979, and two weeks earlier than the 1869-1899 period. It's happened as early as March 13 (in 1990) and as late as June 7 (in 1924).
Lows of the past six days exhibited the following pattern: 40°-42°-41° and 40°-42°-41°.
The day after winter's last below-freezing low (28°), the high jumped to a balmy 75° (and tomorrow's high would rise to 82°).
This was the first Easter Sunday since 1871 to have a high in the 80s, and at 85° it was the warmest on record (until 1962). By contrast, yesterday's high was in the mid-60s, as would be tomorrow's.
This was the 19th day in a row with no measurable precipitation, the longest stretch of dry weather since one of 26 days in October 1973.
A late cold snap saw the morning low tumble to 33°, a year after a low of 32° was reported on 4/17. (By contrast, the warmest temperature this month, 81°, came at the beginning of April.) This morning's frosty low was the coldest reading since March 21.
For the third day in a row temperatures were well above average, and very similar: 77°/57° today, 75°/57° yesterday, and 76°/57° two days ago.
A steady, cold rain, sometimes on the heavy side, fell throughout the day, amounting to 2.28" - a record for the date. The high was only 46°, seventeen degrees below average.
My flight to Pittsburgh, for an Easter visit to see my mother, was delayed six hours due to inclement weather in the Mid-Atlantic states. 1.62" of rain fell, with more than half of it coming down between noon-3 PM. It was also chilly, as the high got up to just 49°, fourteen degrees below average.
Today's high of 79°, sixteen degrees above average, came after a seasonable low of 45°.
Under sunny skies, today's high reached 71°, the last day this month to be in the 70s. April had seven 70-degree days in total, one fewer than the exceptionally mild March.
