Talk:Baltimore weather

Extremes removed
To anyone wondering why there are no longer records displayed for Baltimore:


 * 1) After a closer examination of the [ Accuweather] source that provides 4F (in March 1996) as the March record low, the coldest it ever reached in March 1996 at the Customs House, the station for downtown Baltimore at the time, was 17F.
 * 2) Some of the record highs cited by both Accuweather and The Weather Channel are suspect, including the 97F in March 1998 and 85F in December 1998 as reported by TWC; the highs for BWI both months was 89F and 77F, respectively. It turns out the Customs House station was situated on the roof-top, which is well-documented to produce suspect data. It is impossible to know which parts of the Customs House data from 22 July 1950 to 1999 are acceptable and which are contaminated.
 * 3) The other option is to use part of BWI data from 22 July 1950; the obvious problem is many monthly all-time record lows that were set at Customs House before the July 1950 switch to BWI were readily shattered: namely &minus;7F in January 1984, 4F just recently in March 2014, and the record low for each of May thru October; on the same occasions, Customs House has come nowhere close to BWI in terms of lows. Given the prior consensus to use temperatures from downtown Baltimore, this option would be inappropriate. " My master, Annatar the Great, bids thee welcome! " 18:35, 4 April 2014 (UTC)
