Temperatures had topped 80 degrees by about 12:30 p.m., and rose quickly, with 85 degrees recorded at BWI Airport and 86 degrees at the Sun weather station as of 4 p.m.
That surpassed the forecasts of both the National Weather Service and AccuWeather.com. The National Weather Service had been predicting highs in the upper 70s, while AccuWeather called for a high of about 82.
It was a few degrees shy of the hottest April 15 on record for Baltimore. The record is 88 degrees set in 1941.
But it was the hottest day of the year so far. The next hottest, March 23, Baltimore hit 83 degrees.
There could be a better chance for a heat record Monday, and in the least it should be another hot day. Forecasters are calling for the mid- to upper-80s, while the record is 90 degrees.
Get out and enjoy the sun while you still have a few hours of weekend left.
