10:00 pm update: Severe weather warnings have ended in the region. Storms are weakening as they move across northern suburbs. They should continue to die out over the next hour or so.
9:30 pm update: It’s the summer that just won’t quit when it comes to storms around here. Activity rolled out of the mountains and into our region this evening, and it’s now crossing northern parts of the area. These storms have been putting out a ton of lightning, in addition to causing some isolated severe weather worries. There is some risk of damaging winds and large hail with the worst of storms, although most spots that see them will mainly see heavy rain and lightning.
Keep an eye out for pop-up storms for the rest of the afternoon. Some of these storms will feature torrential downpours and small hail. Otherwise, we continue to be stuck in this hot and humid stretch of weather with no real break in sight until the end of this week.
Through tonight: Isolated thunderstorms will continue to pop up during the remaining daylight hours. These storms will be slow-moving and loaded with rain, so some urban flash flooding is possible in areas where the storm cells linger long enough. Warm and quite muggy overnight, with lows in the mid-70s and areas of patchy fog.

Tomorrow (Monday): Another hot and humid day with isolated afternoon thunderstorms. Afternoon highs will be in the mid- to upper-90s with heat-index values over the century mark. Mostly cloudy, warm and humid again tomorrow night with lows in the mid- to upper-70s.
