It'll be tough to get any rain over the next 10 days
A triple-digit heat wave is settling into Houston, leaving just a glimmer of hope for any rain.

HOUSTON, Texas (KTRK) -- Rain will be difficult to find over the next couple of weeks as we look to be entering the hottest and driest stretch of summer.

Temperatures Tuesday afternoon will climb to near 100 degrees once again. We will have more clouds in the sky than we've seen the last couple of days, but they won't offer up much shade. One silver lining is that drier air mixing down during the afternoon should keep the heat index from getting out of hand. Peak heat index values will range between 103 and 107 degrees in most places.

Are we going to be dealing with triple-digit heat all week?

Pretty much. High temperatures will likely hit 100 nearly every day left this week...and most of next week, too. Humidity levels will also increase by the weekend, pushing the heat index higher. A Heat Advisory may be issued by the National Weather Service later this week.

There's really no rain in the forecast?

Rain chances are slim to none over the next few days. Dry air is over the state of Texas and a heat dome will help reinforce this drier pattern. It's not until the second half of the week when the heat dome moves west of Texas, allowing for an increase in Gulf moisture. We've got a 10% chance for rain on Friday and Saturday, and that's about the best we can do right now. That said, there is an increasing concern for drought conditions to settle in quickly over the next two weeks across portions of Southeast Texas with this hot and dry forecast.

What's happening in the tropics?

Lala is no longer impacting Hawaii but still churning out there in the central Pacific. Meanwhile in the Atlantic, we are watching some tropical waves and Saharan dust emerging from Africa. For a more in-depth discussion on what's happening in the tropics, visit our Daily Tropical Update page.
