Houston set its record for most consecutive 100+ degree days on Monday, with 15. It has since added two to the record yesterday and today

Houston Chronicle science blogger Eric Berger complained:

It’s bad enough that this August is nearly 3 degrees warmer than any previous month in the city of Houston’s historical record. And that we’re in the midst of a 16-day [now 17] streak of 100-degree days that’s showing no signs of ending soon.

That’s bad.

It appears the high pressure bringing brutal heat and snuffing out thunderstorm development may persist through the weekend.

Houston is now just four shy of its summer long record of 100+ days (32, set in 1980). If the current forecast holds, it will tie that record on Sunday.

THE CITY OF HOUSTON HAS NEVER RECORDED AN AVERAGE MONTHLY HIGH TEMPERATURE GREATER THAN 100 DEGREES. THE CURRENT AVERAGE MONTHLY HIGH TEMPERATURE FOR AUGUST IS 101.0 DEGREES. IF CURRENT TEMPERATURE FORECASTS FOR WED/THU VERIFY...THE CITY OF HOUSTON WILL ONLY NEED TO AVERAGE A HIGH TEMPERATURE OF 97.9 OVER THE LAST 13 DAYS OF THE MONTH TO ACHIEVE AN AVERAGE VALUE OF 100.0 DEGREES.

Meanwhile, Wichita Falls had its 80th 100 degree day yesterday, setting the record for most 100 degree days in a year. The old record was 79 in 1980.

Although Dallas fell two days short of its record for most consecutive 100+ days earlier this month (tallying 40 such days, whereas 1980 had 40), it had a stifling low temperature of just 86 Tuesday for the fourth time this summer. Wunderground’s Jeff Masters discussed the significance of this:

The low temperature yesterday morning at Dallas/Fort Worth International was 86°--the all-time highest minimum temperature recorded there. This is the 4th time this summer Dallas has had an 86° minimum temperature, with the other dates being July 26, August 3, and August 4. Prior to this year, the hottest minimum temperature ever recorded in Dallas was 85° on September 1, 1939 (which they also matched this summer on July 25, August 7, and again this morning.) Thus Dallas has matched or exceeded their all-time hottest minimum temperature seven times this year.
