\"\"A thick plume of Saharan dust is crossing the Gulf of Mexico, barreling into the Texas<\/strong> coastline as of tonight, Sunday, June 29<\/strong>. While light haze will already be visible by morning, the bulk of the dust cloud<\/strong> is expected to sweep across the region by late Sunday night into early Monday<\/strong>, leaving a noticeable mark on sky visibility, air quality, and health<\/strong> through Tuesday<\/strong>.<\/p>\n

<\/h3>\n

Hazy skies from San Antonio to Austin by Sunday morning<\/strong><\/h3>\n

As of Sunday morning<\/strong>, residents along the Texas Gulf Coast<\/strong> and across cities like San Antonio<\/strong> and Austin<\/strong> should expect slightly hazy skies<\/strong>. Early temperatures<\/strong> will be comfortable<\/strong>, holding steady in the mid to upper 70s\u00b0F<\/strong> (24\u201326\u00b0C<\/strong>).<\/p>\n

By midday<\/strong>, San Antonio<\/strong> will warm up quickly, hitting 90\u00b0F (32\u00b0C)<\/strong> around 1 p.m.<\/strong>, and peaking at 93\u00b0F (34\u00b0C)<\/strong> in the late afternoon. Thanks to high humidity levels<\/strong>, the heat index<\/strong> will hover near 100\u00b0F (38\u00b0C)<\/strong>, increasing the perception of heat.<\/p>\n

Some isolated showers and weak thunderstorms<\/strong> may develop by the afternoon, but rain coverage<\/strong> will be sparse, with only a 20% chance<\/strong> of precipitation. That means most of the region will stay dry<\/strong> through the evening hours.<\/p>\n

<\/h3>\n

Dust surge intensifies overnight across East Texas<\/strong><\/h3>\n

The real impact of the Saharan dust plume<\/strong> will unfold after sunset. Unlike the dramatic wall-like haboobs<\/strong> sometimes seen from Arizona<\/strong> to West Texas<\/strong>, this event will be more gradual<\/strong>. You\u2019ll notice the skies growing hazier overnight and especially by Monday and Tuesday<\/strong>.<\/p>\n

The heaviest concentrations<\/strong> of airborne particles will accumulate over East Texas<\/strong>, affecting cities like Houston<\/strong>, Beaumont<\/strong>, and Lufkin<\/strong>. Meanwhile, moderate dust levels<\/strong> will also be felt along the Interstate 35 corridor<\/strong>, including New Braunfels<\/strong>, San Antonio<\/strong>, and Austin<\/strong>.<\/p>\n

The dust particles<\/strong>, which have already traveled over 4,000 miles<\/strong> from the African continent<\/strong>, contain microscopic minerals<\/strong> like silica and quartz<\/strong>. These particles can be inhaled deeply<\/strong> and may irritate sensitive respiratory systems<\/strong>. While the general population is unlikely to experience severe issues, people with asthma<\/strong>, cardiovascular conditions<\/strong>, or chronic respiratory illnesses<\/strong>, along with young children<\/strong> and the elderly<\/strong>, are at higher risk<\/strong> for complications due to the reduced air quality<\/strong>.<\/p>\n

<\/h3>\n

Less dust, same heat by midweek<\/strong><\/h3>\n

By Wednesday<\/strong>, concentrations of Saharan dust<\/strong> will begin to fade across Texas<\/strong>, with skies slowly clearing<\/strong>. However, temperatures will remain elevated<\/strong>, staying consistent through the midweek.<\/p>\n

From Tuesday through Thursday<\/strong>, San Antonio<\/strong> is expected to see highs between 91\u00b0F and 93\u00b0F (33\u201334\u00b0C)<\/strong>. Overnight lows will remain mild<\/strong>, staying in the mid-70s\u00b0F (24\u00b0C)<\/strong>. There may be a few brief showers or weak storms<\/strong>, but rain chances will remain very low<\/strong>, between 10 and 20%<\/strong>.<\/p>\n

Looking ahead to Friday, July 4<\/strong>, temperatures will climb again<\/strong>, with San Antonio<\/strong> forecast to reach the mid-90s\u00b0F (35\u00b0C)<\/strong>. Despite partly cloudy skies<\/strong>, high humidity<\/strong> will push the heat index<\/strong> back near or above 100\u00b0F (38\u00b0C)<\/strong>. Rain looks unlikely<\/strong>, making it possible for most Independence Day outdoor events<\/strong> to go on uninterrupted.<\/p>\n
