2010: a tally of busted/tied weather records
So let's see if I can gather up a complete record of all the Baltimore weather records broken or matched so far this year. Feel free to add more if you think I've missed something:
1. Hottest summer: The average temperature at BWI-Marshall from June through August (the meteorological summer) was 79.3 degrees. That broke the previous record of 79.1 degrees, set in 1943.
2. Most 90-degree days: The total now stands at 56 days, counting Wednesday 9/8. We broke the previous record of 54 days set in 1988.
3. Most snow: The official total at BWI was 77 inches (for the season). That broke the previous record of 62.5 inches set in the winter of 1995-96.
3. Snowiest month/snowiest February: The total was 50 inches, beating the previous record of 40.5 inches in February 2003.
4. Most 100-degree days: Seven days. This was a tie, matching the total in 1988.
5. Record-high daily temperatures were set on 10 dates: April 5 (84 degrees); April 6 (90 degrees); June 23 (97 degrees); June 24, (100 degrees); June 27, (100 degrees); June 28 (99 degrees); July 6 (105 degrees); July 7 (101 degrees); July 24 (101 degrees); July 25 (100 degrees);
6. Record-high minimum temperatures: set May 3 (69 degrees); July 24 (82 degrees)
7. Warmest month/warmest July: Temperatures in July averaged 81.5 degrees. This matched the record for the warmest month and the warmest July, first set in 1949 and matched in 1995.
8. Hottest average daily high temperature: July's daily highs averaged 92.5 degrees, beating the previous record of 91.9 degrees, set in 1988.

Thanks, Mr. Weather Blog Dude, for officially documenting what we've all been talking about...Baltimore's totally awesome bipolar weather this year.

Please note the snow is not a rebuttal of climate change but the opposite. The key factor was the abnormal amount of precipitation, which is what the theory of climate change suggests will happen.

Wasn't the snowfall in December 2009 also a record for the month of December? (I know it's not in calendar year 2010, but December 2009 was part of meteorological winter 2010. And you MUST include it to get the record snowfall for the season (item 3).)
FR: No. After a closer look, it turns out that December 2009 was initially listed as the snowiest December on record, with 22.2 inches. However, an adjustment to the total made by the National Weather Service after the discovery of measurement errors by an FAA contractor at BWI-Marshall later reduced the total to 201. inches. That slipped it below the record of 20.4 inches established in 1966. December 2009 was the wettest on record, with 8.06 inches of melted precipitation. That beat the previous December record of 7.44 inches set in 1969. But I can't find a reason to include that in a listing of 2010 records.
