Saturday: Perfect timing to set a D.C. record

By Dan Stillman

* Searing heat: CWG's Full Forecast | Predict Saturday's high temp *

Usually when we talk about flirting with record highs this time of year, the bar is set pretty high. 98, 99, often the the low 100s is what it takes to tie or set a record. It just so happens that tomorrow's date, July 24, carries the month's lowest record high temperature for Washington, D.C. -- 96 in 1987 (and at least one other previous year). With highs tomorrow expected to easily reach the upper 90s, and probably near 100 or into the low 100s, it seems fairly certain that we'll break that record.

After July 24th's 96 degrees, the next lowest record high is 99, which is the highest temperature recorded on July 11, 12, 29 and 30. The highest temperature on record for any date in D.C.? 106 on July 20, 1930, and on Aug. 6, 1918.

What seems unusual is that Washington has a July high temperature record as LOW as 96 degrees...I'm also surprised that the city has never gotten hotter than 106 degrees. All surrounding states have reached 110, mainly during the 1936 heat wave...even Wisconsin, Minnesota and parts of Canada have exceeded 110 degrees.

I'm guessing some places, "Wisconsin, Minnesota and parts of Canada" have had higher temps due to less moisture in the atmosphere. Humidity limits the range of temperatures. Even in the Amazon basin it rarely reaches 100 degrees. Around here our air masses that reach or exceed 100 degrees are usually relatively dry. This Saturday is one of the exceptions. Not looking forward to the temps and humidity tomorrow.

Remember, no Global warming now.

Do they keep records for dew point? I guess it wouldn't be official, but the Thomas Point station (TPLM2) is reporting a dew point of 84.9F (air temp=86 -> heat index=109.4). The nearby CBIBS-Annapolis buoy shows humidity at 80% with air temp @ 87F which works out to a dew point of 80F.
