This year's colder-than-normal start is looking like it could stretch nearly to summer, with Baltimore appearing likely to go later than it has in at least five years without hitting 90 degrees.
In 2011, Baltimore-Washington International Thurgood Marshall Airport didn't break the 90-degree barrier until May 26, when it reached 91 degrees. Forecasts through that date this year don't predict anything above the lower 80s.
In four of the past five years, BWI has hit the 90s for the first time in April -- late in the month in 2009, but as early as the 6th in 2010 and the 10th last year.
May is pacing to be the first warmer-than-normal month this year, at 2.3 degrees above average through Monday.
Through March, winter's chill had 2014 off to its seventh-coldest start on record and the coldest since 1978. April was then just slightly colder than average.
The year's streak below 90 degrees could end before meteorological summer begins in June -- the U.S. Climate Prediction Center forecasts strong odds of warmer-than-normal temperatures for the last several days of May and first few days of June.
