After storms shifted north of our area early, early this morning & an outflow boundary popped a storm or two in the northwest this morning, outflow boundary will pop a some storms this afternoon-evening. These storms would tend to our over the northwestern half of the viewing area (Lafayette & northwestward). An isolated severe storm or two is possible.
Otherwise, it looks dry, very warm to hot & muggy with highs today 77-90 (coolest northwest) with most of the area in the 85-90 range. Heat indices will run 79-97 (coolest northwest). Most of the area will see heat indices in the 90s.
As I type this, our WLFI ob site weather station reads 87 with a heat index of 95 with southwest wind at 7 mph.
After 60s for lows tonight (with some patchy fog), highs tomorrow should reach 83-90 with heat indices of 85-96.
