Houston weather: Heat advisory on Wednesday
A heat wave begins today and the season's first heat advisory is in effect! Be prepared for high temperatures in the upper 90s and low 100s for at least a week and probably the next two weeks. Chances for rain are low with a quick moving storm possible tonight, but overall, expect hot sunshine with feels like values above 105 in the afternoon.
HOUSTON - Today is Day 1 of a heat wave, and millions of Texans are under a heat-related alert.
A developing "heat dome" will bring highs in the upper 90s and low 100s for at least the next two weeks.
SUGGESTED: Recognizing heat exhaustion vs. heat stroke
Our area is under a heat advisory from 1 p.m. to 7 p.m. today to warn of a heat index value above 105. Parts of the Rio Grande Valley could see highs near 110 and a heat index near 120!
High temperatures across Texas will be even warmer tomorrow with lots of triple-digit heat and very high humidity, so more heat advisories are expected.

With a jet stream pattern that favors a strong ridge of high pressure over Texas and a dip in the jet stream over both the east and west coasts, we may set up a "blocking" pattern that results in a long period of hot, sunny weather.
SUGGESTED: Staying safe in dangerously high temperatures after heat advisory issued for Texas
The outlook for next week from NOAA shows a high likelihood for a continuing heat wave for Texas and much cooler air for the western US.
Here is advice from the National Weather Service for dealing with extreme heat:
"Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances."
