* Heat advisory noon to 8 p.m. Wednesday *

The heat trickled into the region today. Tomorrow it’s on full blast. Add on top of that moderate-to-high humidity levels, and it’s not only uncomfortable, but potentially hazardous. Remember to drink plenty of water Wednesday and take time to cool off if you’re outside for long periods.

Through Tonight: It feels like the thick of summer, although we await the “official” start of the season for another day. Skies are mostly clear, with lows ranging from the upper 60s in the cooler suburbs to the low-to-mid 70s downtown.

Wednesday: An intensely hot sun beats down on us (wear sunscreen - UV Index to be very high to extreme), raising the afternoon mercury into the mid-to-upper 90s. Factor in moderate-to-high humidity levels (dew points 67-71), and it will feel like 100-105. There’s not much of breeze to offer relief, with winds from the northwest around 5-10 mph at best.
