One rare Spring storm system. Several bookmarks in the weather history books.
For starters, Mount Lemmon woke up to a dusting to 1″ snow yesterday. This marks the first recorded May snowfall since 2008. The record for most May snow is 7.8″, set on May 7th, 1995.
Tucson’s daytime high of 68° Tuesday is noteworthy on a couple of levels. It marks the 2nd coolest May afternoon in the last 30 years, last occurring on May 21st, 2009. Between Friday’s daytime high of 104° and yesterday, the temperature dropped an incredible 36°. This is the largest 4 day temperature drop during the month of May.
Finally, the Bisbee-Douglas Airport recorded 0.07″ rain on Tuesday. While it’s not much, it does set the record for most rainfall on May 9th. The old mark? A whopping trace back in 1997.
