The weather pattern that brought heat that lingered around 100 degrees has passed, but it won't be forgotten soon. It brought some notable weather extremes and set at least three records in the Baltimore area.
Here's a review of the past two weeks or so, by the numbers:
- 67: Wind speed, in mph, at BWI Marshall Airport during the derecho storm June 29.
- 675,000: Power outages the storm caused in the territory Baltimore Gas and Electric Co. serves; later, heat and smaller storms raised the number as high as 748,000 outages within a week.
- Nine: Days it took BGE crews to restore all the storm-related outages.
- 12: Consecutive days with high temperatures at 90 degrees or above at BWI, starting June 27.
- Eight: Place that 12-day streak ranks among the longest stretches of 90-degree-or-above high temperatures at BWI; the record is 25 days, set in 1995.
- 104: Highest temperature recorded at BWI during the stretch, on July 7, the hottest day of 2012 so far in Baltimore.
- Three: Temperature records set or tied at BWI over the weekend, including the 104-degree record high Saturday, a 100-degree high Sunday, and an 82-degree low Sunday.
There was some confusion over Saturday's high, as it was reported in The Sun's Sunday editions and online Saturday evening as reaching 103 degrees at BWI but later corrected to 104 degrees. That's because the National Weather Service office in Sterling, Va., which covers the Baltimore area, issues a preliminary daily climate report around 5:30 p.m. each day based on weather data through about 4 p.m. that day, said Steve Zubrick, science operations officer at Sterling.
While BWI had recorded a high temperature of 103 degrees at about 3:58 p.m., the 104-degree mark wasn't reached until 4:16 p.m. Weather service meteorologists can't easily reprogram when their instruments report the high temperature, and the official report for the day doesn't come out until after 1 a.m., when the 104-degree high was made official, Zubrick said.
Either way, it was the hottest July 7 on record in Baltimore, easily surpassing the old record of 101 degrees.Copyright © 2015, The Baltimore Sun
