August begins with another round of July-like weather, with thunderstorms expected today, followed by a possible heat wave - and more thunderstorms.
"Heat index values, particularly in urban areas, could approach 100 degrees Friday through Sunday," according to the National Weather Service.
Today, showers and thunderstorms could develop by midday, with "gusty winds and heavy downpours" possible.
The threat could continue through the afternoon rush hour, but should diminish by nightfall.
Today's high should be in the mid 80s, but Thursday could see the low 90s, followed by the mid 90s Friday through Sunday.
