PM Update: Some more showers around tonight and into a much cooler Friday.
It initially looked like we’d add a few days of 90s in this heat streak, but it only ended up being one today. It was the first time we’ve reached or topped 90 degrees in the city in two weeks, and it was brutal with the high humidity. Then storms came along to help knock back the heat a bit. Those storms are a harbinger of a new air mass that’s about to set up shop for a few days.
Through tonight: The evening round of storms is moving away to the east, and the next few hours should be quiet. Partly to mostly cloudy conditions persist into the night. A couple more showers may move through late tonight. Maybe even a rumble as the cold front slinks this way. Lows make the mid-60s to around 70. A few patches of fog may form.
Tomorrow (Tuesday): Some showers and perhaps a rumble are around in the morning. Activity should tend to wane as we go through the midday and get deeper into the afternoon. Skies are probably breaking by late day, as daytime highs try for the low and mid-70s. Humidity is coming down through the day, too, on a gusty northwest wind.
