Update: As of 4 p.m., Reagan National Airport had reached at least 90 degrees today, marking the first 90-degree day of 2011.
67. Does that number mean anything to you? Oh how quickly we forget (or want to forget). That was the number of days last year the high at Reagan National Airport reached 90 or higher, good enough to tie the previous record for 90-degree days in D.C. - 67 in 1980.
I’m fairly sure this is a record very few would like to shoot for again this year. So far so good: The average date for the year’s first 90-degree day (May 19 based on 1971-2000 data, May 17 based on 1981-2010 data; stats courtesy CWG’s Ian Livingston) has come and gone without National reaching 90; we’re running quite a bit behind last year’s pace, when May 26 marked our third 90-degree day of the year; and our summer outlook predicts a tamer summer than the last, despite the early-season heat here now.
But today has the potential to be the season’s first 90, and if not we’ve got several more shots in our latest forecast into next week. Once we do get started with 90s, where do you think we’ll stop?...
