PM Update: Summery Saturday, fall-like Sunday, showers in the middle

The work week ended beautifully with lots of sun and temps cresting near 80 degrees. The weekend presents two very different types of days. On the first “official” day of fall Saturday, it’s summer-like, with highs 84-88. On Sunday, fall fully expresses itself with cooler, breezy conditions. The transition occurs late Saturday, when a cold front produces possible showers and thundershowers.

Through Tonight: Partly cloudy and not as chilly as the last few nights. Lows range from the mid-50s in the cooler suburbs to the low-to-mid 60s downtown.

Saturday: It’s warm with even a modest touch of humidity through the early-to-mid afternoon. Between 2 p.m. and sunset, showers and thundershowers develop from west to east. They’re scattered, so not everyone gets wet, but I’d give 60 percent odds. A few of the thundershowers could produce a strong wind gust or two. Highs range from 84-88. Winds are from the south at 10-15 mph.

Saturday night: Lingering showers Saturday evening gradually fade and clearing begins after around 10 p.m. It’s a little breeze and turns cooler, with lows 52-59 (suburbs-city).

Sunday: It’s mostly sunny and breezy. Highs are around 70 - chilly enough to feel cool in the shade, with winds from the northwest at 10-20 mph.
