This afternoon tops out at a mostly sunny 89°, with a south-southwest breeze at 5 to 10 mph keeping things from feeling too oppressive. Tonight stays mild and mostly clear, with lows only dropping to around 73°.
Sunday is when it turns into a real heat day: sunny skies, a high near 95°, and heat index values climbing as high as 99°. The wind shifts southwest at 5 to 10 mph, but it won't do much to cut the mugginess. If you've got plans at the parks or anywhere without shade, plan around the middle of the day — that's when the heat index peaks.
Sunday night offers only modest relief, with clear skies and a low around 74° — and even overnight, the heat index is expected to run as high as 97°. That kind of overnight warmth means less of a chance for homes and bodies to cool off before round two.
Monday repeats the pattern almost exactly: sunny, a high near 95°, southwest wind 5 to 10 mph, then another mostly clear night with a low around 74°. Two straight days in the mid-90s with heat index values pushing toward 100° is enough to plan around — hydrate, check on anyone without reliable air conditioning, and shift outdoor exercise to the cooler morning hours.
