Forecast temperatures over the next week.
The triple-digit drumbeat isn't anything too unusual for the Bayou City in the summer. However, this round of high heat will break records and possibly set a new all-time record.
Depicted above is the temperature forecast from various computer models. Note the white line which represents the model average. It approaches 105° could even go higher. In fact, it is possible that the highest ever mark of 109° set memorably on August 27, 2011, could be challenged. During that month in 2011, all but one day registered 100° or higher.
Here are the forecast temperatures and records for the up-coming misery:
Aug 7 102° 104° (2003)
Aug 8 102° 104° (1962)
Aug 9 103° 106° (1962)
Aug 10 106° 104° (1962)
Aug 11 106° 102° (2011)
Aug 12 105° 105° (1962)
Additionally, there will be enough humidity to push the heat index over 110°. This is a depiction of the forecast for how hot it will feel. It is a reminder to be sure you exercise caution when outside, especially keep the young ones in and check in on elderly neighbors.
Whenever southeast Texas roasts like this, it's because a ridge of high pressure is parked over the state. Under the ridge, the air is sinking and compressed, leading to 100° days. Here is the upper-level wind pattern depicted centered firmly over southeast Texas by late Sunday:
The ridge won't break down appreciably until the end of next week. As it shifts to the west, a slight chance of isolated showers could return. Ah...summer in H-town!
