For the fifth year in a row rain fell on this date. Today's measured 0.15" and fell between 7 AM and 1 PM.
0.66" of rain fell in a 30-minute period (7-7:30 PM) and within that half hour 0.44" fell during the fifteen minutes between 7:15-7:30.
A pre-dawn shower that amounted to just 0.07" of rain, ended an extended dry spell of twenty-six days, the second longest in the 1960-2020 period. (Only a 35-day drought that occurred two years earlier in May/June 1999 was longer.) Then, between May 21-29 rain would fall on eight of the nine days, amounting to two inches.
Today was the fourth day in a row with rain, and it culminated in a record amount for the date - 2.18". The four-day total of 3.91" accounted for 3/4 of the month's total rainfall. This was the fourth year since 2000 to have more than an inch of rain fall on this date. Also, today's amount was double the amount that fell last year on this date.
For the second day in a row temperatures were in the 90s, with today's high of 92° a record for the date. This was the earliest instance of back-to-back 90s since April 2002. Besides the high temperature setting a record, the low of 75° did as well. It was also the second warmest low temperature ever recorded in the month of May (warmest is 76°, set on May 31, 1987).
This morning's low of 60° was the first low in the 60s this year, the latest date for this occurrence since 2003 (when it happened on 5/30). Under partly cloudy skies, today's high rose to 82°. (Last year's first 60+ low was also late, occurring on 5/15.) Since 1980, the typical date of the first 60+ low has been 5/2.
