Screen Shot2015-07-19 20_30_01Sunday lived up to expectations and justified the heat advisory across much of the Mid Atlantic. The high temperature at Baltimore’s BWI was 97°F, but with the dew point temperature holding around 70°F, it felt like 104°F. The heat was only beat by 98°F at Washington’s Reagan National. Today was the hottest of the year 2015 (so far). It was not a record by any stretch.  But considering that we have not hit the 90s in almost a month, I wanted to break down the numbers and explain why I have been saying that this has not been much of a summer.  Beyond the record June rain, the typical summer heat has been absent from central Maryland. At least by local standards.

By the Numbers

97°F – High temperature in Baltimore today (July 19, 2015)

87°F – The average high temperature on this date.

103°F – Record high set in 1930.

3 – Days in a row with records still on the books over 100 degrees (July 19-21 1930).

25 – Days since the last day reaching 90 degrees.

94°F – The temperature on that last day of June 23.

7 – Total Days (so far in 2015) at or above 90°F in Baltimore.

Comparing to the past five years

We had some hot summers starting this decade, but there has been a downward trend since peaking in 2012

We do have one or two more days in the 90s ahead in this stretch. Check back for the forecast update.
