Dallas weather: July 18 morning forecast
We are heading into a much drier and hotter pattern. Today will be the coolest day on the 7-day, but highs are still expected to climb into the mid-to-upper 90s.
DALLAS - A stubborn low-pressure system that dumped over two feet of rain in parts of Texas is finally exiting the state, paving the way for a dramatic shift to extreme summer heat and triple-digit temperatures next week.
While the departing system leaves behind swollen creeks and rivers across central and southern Texas, North Texas is expected to remain largely dry. There is a slim 10% chance of isolated morning and afternoon showers on the radar, primarily confined to areas north and west of the Dallas-Fort Worth metroplex.
Saturday is projected to be the coolest day of the week, with seasonable afternoon highs reaching the mid- to upper 90s. South winds of 10 to 20 mph, with gusts up to 30 mph, will keep the air moving but will also pull hotter air into the region.

Timeline:
If you've got outdoor plans for today, know that yes, it is still hot. You need water, you need sunscreen. But as we step into the next week, this really doesn't hold a candle to the kind of heat that we expect moving forward.
An expansive high-pressure system is forecast to move overhead and park itself over Texas for the entirety of the upcoming workweek, effectively shutting off any chances of rain across central and northern parts of the state.

Deadly Texas Flooding: Sunday, July 18 morning update
On Sunday morning, residents and local officials continue to clear the damage left behind in the aftermath of this week's deadly flooding. FOX 4 Meteorologist Josh Johns is in Kerr County as those floodwaters recede.
Temperatures are expected to climb to the upper 90s on Sunday before hitting triple digits on Monday. By midweek, afternoon highs are projected to reach between 102 and 103 degrees.
With the average high for this time of year sitting at 96 degrees, the upcoming heat wave is expected to trigger widespread heat advisories and potential extreme heat warnings. When factoring in humidity, heat index values—or "feels-like" temperatures—are projected to soar between 105 and 110 degrees by mid- to late week.
Please take heat precautions, limit outdoor exposure during peak daylight hours, and stay hydrated as the state transitions into a prolonged period of intense summer heat.
