Severe thunderstorm watch

No alerts have been posted, but the NWS noted that a "severe thunderstorm watch may be needed during the day on Thursday."

What's next:

The prime time for a potential heat wave next week will be from Sunday through Thursday. While relatively few locations may actually hit the 100-degree mark, the combination of high temperatures and elevated humidity levels will make it feel significantly hotter.
