South Florida's heat continues with Saharan dust limiting rain chances

In South Florida, including the Keys, residents are facing hot, hazy, and humid conditions with a heat advisory in effect from 10 a.m. to 6 p.m. Heat index values are expected to reach as high as 112 degrees, with a layer of Saharan dust moving in from the southeast. This dust will give the sky a gray-brown appearance and limit rain chances for the next few days, with only isolated showers possible. Winds are forecasted to shift to become more easterly by Thursday, gradually strengthening heading into the weekend as an area of high pressure builds back towards the region. The Saharan dust layer is expected to erode by Friday, allowing for higher rain chances and a slight cool down over the weekend. While neither Saturday nor Sunday will be washouts, spotty storms are likely to return to the forecast, bringing highs back to near average in the low 90s. Overnight temperatures will remain warm, offering little relief from the heat, with lows in the mid-70s over the interior and low 80s along the coast. The hazy sky caused by the Saharan dust will create monochromatic sunsets and sunrises, with heat index values peaking between 105 to 110 degrees. Tuesday is expected to be mostly cloudy with a high near 88 and heat index values as high as 100. Wednesday will bring mostly sunny skies with highs near 89, while Thursday will be partly sunny with showers and thunderstorms likely in the afternoon, and highs in the upper 80s. By the end of the week, the Saharan dust is anticipated to move out of the area, leading to higher rain chances and cooler temperatures, with highs returning to the low 90s. The National Weather Service advises residents to stay hydrated and take precautions against the extreme heat.
