forecasters said<\/a>. But light southeast winds off the Gulf Coast will be sending in moisture-rich air that will drive heat index values 10 degrees higher to 105.<\/p>\nIt\u2019s this surge of atmospheric moisture that will make weather dangerous.<\/p>\n

On hot days, we rely on the evaporation of sweat from our skin to cool down. But high humidity makes that process less efficient because the air is already filled with water vapor. The heat index takes this into account to more accurately describe the heat the body experiences, at least better than what actual air temperatures would suggest.<\/p>\n
Because your body\u2019s ability to cool down is compromised, the potent combination of excessive humidity and extreme heat can become dangerous for those performing activities outside. You risk heat exhaustion or heatstroke if you don\u2019t take adequate precautions for the heat.<\/p>\n
If you must be outside, drink plenty of water, wear loose-fitting and light-colored clothing, and take frequent breaks in air-conditioned spaces. Also, never leave children or pets unattended in a vehicle, not even for a minute or two.<\/p>\n
Nighttime relief from the heat will be limited this week, as overnight temperatures through the weekend will stay largely in the 80s, bottoming out around 78 degrees before sunrise.<\/p>\n

Rain chances near July 4<\/p>\n
The upper-level ridge of high atmospheric pressure responsible for the uncomfortable heat in Southeast Texas has shifted northeast, forecasters said, opening the door to rain chances in the region.<\/p>\n
\u201cThis will be accompanied by an increase in moisture moving in from the Gulf,\u201d the weather service said. \u201cAs the moisture plume moves into our region on\u00a0Thursday, shower coverage looks to increase to scattered (25-40%)\u00a0along and south of I-10.\u201d<\/p>\n
Houston on Thursday has a 30% chance of rain in the afternoon under otherwise mostly sunny skies.<\/p>\n
\u201cIf guidance continues to trend towards\u00a0richer moisture further west, rain chances may need to be increased\u00a0for the southern half of the forecast area for Thursday over the\u00a0next couple of days,\u201d forecasters said.<\/p>\n

Although major heat health risks are likely to increase Friday and through the Fourth of July holiday weekend, rain chances are also likely.<\/p>\n
\u201cThe potential for hazardous\u00a0heat will be closely monitored with it being the Fourth of July\u00a0on Saturday,\u201d the weather service said, adding that \u201cwe will continue with these afternoon\u00a0convection\/sea breeze storms through the Fourth of July weekend.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Heat index values, or humidity-driven \u201cfeels like\u201d temperatures, will be in the triple digits across Southeast Texas by…\n","protected":false},"author":2,"featured_media":357101,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[56,58,57],"class_list":["post-357100","post","type-post","status-publish","format-standard","has-post-thumbnail","category-houston","tag-houston","tag-houston-headlines","tag-houston-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts\/357100","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/comments?post=357100"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts\/357100\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/media\/357101"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/media?parent=357100"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/categories?post=357100"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/tags?post=357100"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
