Considerable cloud cover held temperatures about 5 degrees below predicted levels, with highs reaching 75-80. But it was plenty humid and that moisture coupled with an incoming disturbance brings a chance of showers and storms overnight. The disturbance scoots out by Saturday night deeming Sunday the pick of the weekend.

Through Tonight: A few showers and possibly the rumble of thunder are possible between roughly 9 p.m. and 3 a.m. overnight (40 percent chance).  The rest of the night is mostly cloudy with just a 20 percent chance of showers.  It’s very mild, with lows 62-67 (suburbs-city). Winds are light from the south.

Tomorrow (Saturday): There’s a small chance of showers in the morning (around a 25 percent chance), with the best rain chances between roughly 2 p.m. and 8 p.m. (60 percent chance).  Some thunder and a few heavier downpours are possible in this window.  It won’t rain the entire time, but keep a close eye on radar if you have outdoor activities planned.  Highs are around 80 and you’ll notice some humidity.  Rainfall totals are highly variable, but average around 0.25-0.5″.

Saturday night and Sunday: Showers and thundershowers are possible Saturday night, but chances decrease from 60 percent in the evening to 20 percent by the pre-dawn hours.  Lows are around 60.  Skies clear Sunday morning with the balance of the day mostly sunny and not as humid, with highs 80-85.
