Today’s reduction in humidity hardly registered. It remained uncomfortably sticky as highs got up close to 90. It’s a similar situation Saturday before a powerful cold front brings a line of potentially severe thunderstorms into the region late in the afternoon and evening. We’re rewarded with a picture perfect Sunday.
Through Tonight: Someone, somewhere could see an isolated shower/storm before sunset with the juicy atmosphere (just a 10 percent chance). Most of us are partly cloudy and warm, with lows from the upper 60s in the cooler suburbs to the low 70s downtown. Light winds from the south at 5-8 mph.
The weekend: Most of Saturday is actually OK, if you don’t mind the humidity. Highs reach up into the upper 80s, but it feels like 90-95. We see variably cloudy skies with showers and thunderstorms likely (60-70 percent chance) in the 4-10 p.m. timeframe (earlier west, later east). We may see a dangerous line of storms develop with torrential rain, dangerous lightning, damaging winds and hail. An isolated tornado cannot even be ruled out.
Any severe weather should clear out from west to east Saturday evening between 8 p.m. and midnight. A few showers could linger before clearing pre-dawn. It turns noticeably cooler late, with lows ranging from 56-62 (suburbs-city).
Sunday looks magnificent. We should have mostly sunny skies, very low humidity, and fall-like temperatures with highs in the mid-to-upper 70s. Winds will be from the northwest at 10-15 mph.
