Extreme heat expected this week in Houston

Houston’s stormy stretch is over, but the tradeoff is a return to intense summer heat. Temperatures will climb throughout the week peaking at 102°.
Several consecutive days of triple-digit temperatures are possible and heat index values will range between 108 to 110 degrees. This will prompt heat advisories starting as early as Tuesday. Overnight lows near 80 will provide little relief, increasing the risk of heat stress through the upcoming work week.
Monday’s Forecast:
This will most likely be the last day with more typical summertime heat. Temperatures climb to the upper 90s with a feels like number of 106°.

High pressure dome is responsible for the extreme heat:
A very stout ridge of high pressure is strengthening across the Central Plains and will be the dominant weather pattern for us for the next five days.

Once these high-pressure ridges get into place, they will not move for a number of days. We will likely see this high keep strengthening through the week.

This upcoming weekend the high pressure begins to move west, allowing for a weak front to approach the Gulf Coast. This will be the next best chance to see any measurable rainfall in southeast Texas.
Next Weekend
Heat index values will range between 106° to 110° each afternoon. Once the heat index hits 108° heat advisories go into effect.
