We'll see more widespread activity in the showers and thunderstorms today. The peak of the storm activity will be this afternoon into this evening, but some showers could be around during the morning hours too. Downpours are the biggest threat with any of the thunderstorms, so don't be surprised if you get a period of heavy rain today.
Temperatures won't be as warm as Wednesday (87). By noon, look for 70 to 75 degrees across the region. Highs will reach the mid to perhaps upper 70s in the city, mid 70s in the north and west suburbs, and the low 70s at the Shore. You will still notice the humidity though, so even though temperatures are cooler, humidity is not lower.
