The big story for the next several days after all the fairly cool weather in July and August is the return of summer warmth and humidity. There will be periodic chances for storms, with the most widespread coverage expected tonight and into Thursday as a warm front lifts north and an upper level disturbance moves over the area. Given the very moist air mass that will be in place, any storms tomorrow night into Thursday could produce heavy downpours and localized flooding. Also, gusty winds and small hail may be a threat with any stronger thunderstorms. But as has been discussed, much warmer and humid conditions will persist through Sunday and possibly into Monday. There may be a stretch with heat index values reach into the middle to upper 90s, especially Thursday through Sunday.
