Wednesday’s Forecast:
Wednesday brings another mostly sunny and very hot afternoon, with Houston reaching around 100 degrees. There is no Heat Advisory currently posted for Wednesday, but heat index values will still climb well above 100, so the heat remains dangerous despite the lack of an advisory.
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.
These systems are very stubborn and hard to move so expect very hot days with very humid mornings generally in the low 80s. Storm chances will be very hard to find for most of the next 5 days.
The peak of the heat arrives Thursday through Saturday, with highs around 101 to 102 degrees and very little rain relief. Sunday finally brings a slight change, with temperatures falling into the mid-90s and a 30% chance of showers and thunderstorms.
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.
The tropics will stay quiet:
We’ll get long break from our next storm. There is nothing brewing in the tropics for the next seven to ten days in the Atlantic basin.
10 Day Forecast:
After several days of triple-digit heat, temperatures should ease slightly early next week as scattered rain chances return. Highs remain in the upper 90s for most of next week, with only isolated showers expected each day, before temperatures potentially climb back toward 100 by next Friday.
