While we have experienced some seriously beautiful weather so far this August we have also had several very chilly mornings in the Mid-Atlantic. When you average the high and low temperatures together, we rank in the top three coolest months of August up to this point at Dulles and Baltimore. Here is a graphic from the National Weather Service that shows our average temperature so far from August 1st through the 15th compared to the averages and records for the month.
Not once did the thermometer at Dulles or BWI reach 90 degrees in August of 2014. 87 was the hottest day of the month at Dulles, VA on the 5th. If we take a look at Reagan National, while it was also cooler than average, it definitely tells a different story.
The average temperature here is less than two degrees below the normal of 77.1. It did hit 90 degrees, but only once on the 5th. And it doesn't even make the top ten coolest Augusts on record. It really goes to show you how different weather can be just a few miles apart in our region. Now that the month is half over, what can we expect as we end it? Will there be a big warm up?
- 6 to 10 day Outlook
Well, at least a bit of one... The medium range forecast has temperatures near the seasonal average with above average temps nearby . We could hit 90 in there for a day or two if we're lucky (yeah, I wouldn't mind one more). So far, D.C. has had 16 days at 90 degrees or above. On average, we get between 25 and 30 of them in a year. The summers with the fewest 90 degree days were in 1905 and 1886 when there were only 7 days. (Thanks to Alex Liggitt and a previous blog for those last two stats).
