Houston Forecast: Heat Advisory for some today; Feels-like 105°-110°

Another round of afternoon storms with heavy downpours possible today and Sunday.

HOUSTON — Today will be just a tad bit hotter and more humid which has prompted the National Weather Service to issue a Heat Advisory for some of our northern and eastern counties.

Just because your city or town isn't listed under a heat advisory does NOT mean it will feel any cooler nor will the heat be any less dangerous. Heat index values regionwide will be in the range of 105° - 110° at times this afternoon.

Like Friday, the daytime heating will interact with the driving sea breeze and initiate isolated to scattered afternoon showers and thunderstorms. These will be slow movers and with very high precipitable water values means downpours will be likely that could deliver a few inches of rainfall in a short amount of time.

The sun sets and all the activity fades. It will be a warm and humid overnight leading into Sunday and then we do it all over again.

Sunday could be another day of Heat Advisories to start off the month of August. Highs right back into the upper 90s with heat indices in the range of 105°-110°. Afternoon storms look to be a bit more widespread than today though.

Looking down range, there is some minor relief coming our way and it looks to get here by Tuesday. A weak, rare cold front will drop in from the north, as it does so rain chances will begin increasing beginning Monday night and expanding south into Tuesday. With the cloud cover and rain activity we can expect temperatures to be held back slightly, we should see highs only in the upper 80s. If the front makes it far enough south we may even briefly enjoy some lower dew points. It doesn't last long though, by next weekend that front will have lifted back north as a warm front and we return to business as usual for southeast Texas in early August, hot and humid with afternoon storms.
