It may be the dog days of summer, but Baltimore didn't break out of the 70s this weekend, continuing a trend that has this month on pace to be the third-coolest August here on record.
Highs were as much as 10 degrees below normal this weekend at Baltimore-Washington International Thurgood Marshall Airport, the point of record for Baltimore. Saturday, temperatures reached only 72 degrees, the coolest day there since June 21.
Temperatures have been consistently below normal all month -- the daily average temperature at BWI rose above normal on only one day so far this August, on Thursday, with a high of 87 degrees and a low of 64 degrees translating to an average 1 degree above normal. On all other days, average temperatures have equaled or fallen below the norm.
Remarkably, temperatures have also yet to crack the 90-degree mark this month. A high of 89 degrees was recorded Aug. 5, the hottest of the month. There are about eight days in the 90s or hotter each August in Baltimore, on average, and in the past several years there have been between six and 11 such days each August.
It will most likely be the coolest August in more than two decades. The average temperature of 72.3 degrees through Sunday matches the average for August 1992 and is about 1 degree cooler than the average for August 1996.
With a week of the month to go, temperatures are forecast to remain between the 60s and the 80s into September. The best chance of tallying the month's first 90-degree day could come Wednesday, when highs are forecast in the upper 80s.Copyright © 2015, The Baltimore Sun
