flirt with the 100-degree mark<\/a>, getting to 99 degrees in the afternoon. But with southerly breezes and drier air in place, heat index values will rise only a few degrees higher, likely to 103.\u00a0<\/p>\n\u201cThe main wrinkle in the weather Monday is that a decent plume of dusty Saharan air is expected to spread across Texas throughout the day Monday,\u201d the weather service said, adding that the concentration of dust \u201cshould be enough to produce milky blue-white afternoon skies and add a noticeable orange tinge to the day\u2019s sunrise and sunset, depending on timing.\u201d<\/p>\n

Heat index values will be in the triple digits by 3 p.m. Monday along the Interstate 35 corridor, including in Austin, according to the National Blend of Models, a composite weather forecast model.<\/p>\n

\u201cSteady hot and sunny weather is likely to continue as we close out June and kick off July,\u201d the weather service said.<\/p>\n
Forecasters were anticipating the development of slow-moving systems of low atmospheric pressure over the western United States to allow the system of high pressure dominating our region to shift northward.<\/p>\n
\u201cThis should relax the pressure\u00a0gradient over our area with the daytime breezes likely to diminish\u00a0over the course of the week,\u201d the weather service said. \u201cThis change-up only minimally impacts\u00a0temperatures, so daytime highs throughout week ahead are still\u00a0forecast to reach the mid-90s to around 100, with overnight lows\u00a0bottoming out in the mid to upper 70s.\u201d<\/p>\n
Fourth of July forecast\u00a0<\/p>\n

\u201cThe first few days of July continue to look dry and we don\u2019t have rain in the seven-day forecast for most of South-Central Texas,\u201d the weather service said.<\/p>\n
However, forecasters expect the shifting position of the high pressure to allow rain chances back into the outlook. But likely not\u00a0for Austin.<\/p>\n
\u201cAs high pressure lifts\u00a0north, increased easterly flow around its periphery over the\u00a0northern Gulf could bring some rains to the Coastal Plains late
week, ” the weather service said. \u201cTo the west, the amplified trough (of low pressure) should \u2026 spark afternoon\/evening storms during the week, though it is highly unlikely that any of this activity will reach the southern Edwards Plateau and Rio Grande Plains.\u201d<\/p>\n

So will we be able to enjoy Fourth of July fireworks without fear of being rained out on Saturday?<\/p>\n
\u201cFor now, the general\u00a0expectation is that it\u2019ll be seasonably hot and dry for Independence\u00a0Day festivities (with less than 10% of models in the latest\u00a0model blend showing any rain),\u201d forecasters said.<\/p>\n","protected":false},"excerpt":{"rendered":"A dense plume of Saharan dust (seen here in\u00a0purple and blue)\u00a0in Texas on Monday could be concentrated enough…\n","protected":false},"author":2,"featured_media":354242,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[27,29,28],"class_list":["post-354241","post","type-post","status-publish","format-standard","has-post-thumbnail","category-texas","tag-texas","tag-texas-headlines","tag-texas-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts\/354241","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=354241"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts\/354241\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/media\/354242"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/media?parent=354241"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/categories?post=354241"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/tags?post=354241"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
