Tonight: Skies turn mostly cloudy as we get into the evening. Scattered showers are likely during the evening into the overnight, mainly after 8 p.m. or so, and maybe an isolated thundershower. Humidity levels creep a bit higher as lows settle in the upper 50s to low 60s. Confidence: Medium-High

A look ahead

Heat and humidity are on the rise Friday and Saturday. Friday highs could reach near 90 to the low 90s with just the chance of an isolated late-day storm. Saturday we could be talking mid-90s, and with moderate humidity, that could mean a heat index approaching 100. Both days should be partly to mostly sunny with only the chance of an isolated shower or storm. Confidence: Medium

Sunday looks to start with some sunshine as temperatures make their way back toward highs well into the 80s and perhaps near 90. Still humid, too, before a cold front brings increasing clouds and a chance of strong storms during the afternoon into evening. Confidence: Low-Medium
