Set rain chances at 20% or less for Wednesday with only spotty showers expected for Thursday, Friday, and Saturday. Those drier afternoons will come with slightly higher temperatures as metro Baton Rouge approaches 100° by the end of the week.

High pressure aloft will maintain the “heat dome” that has impacted much of the central and southern U.S. over the past many days. While the next several days may not be entirely rain-free, daily rain chances are set a 20% or less for Wednesday through Sunday.

For metro Baton Rouge and much of the WAFB area, muggy morning starts will be in the mid and upper 70°s over that five-day stretch while afternoon highs will climb to or near 100° by the weekend. The above-normal temperatures and abundant Gulf humidity will drive peak heat index readings into the 105° to 110° range each day, prompting a HEAT ADVISORY for Wednesday with additional advisories likely for Thursday through Sunday.

The outlook into next week offers some hope for a break in the current hot-and-dry weather pattern, with scattered mainly-afternoon thundershowers expected to return by Monday and continue through the final days of June. Those afternoon rains should provide relief from the afternoon heat for parts of the viewing area each day, but highs will still manage to reach the mid 90°s on most days before those daily rains arrive.
