As temps pushed toward 90 for the third-straight day, the region hunkered down under another official heat wave Monday.
The heat wave became officials as temperatures reached 90 by mid-afternoon. The high temperature on Saturday was 91 and Sunday was 93.
The heat wave was expected to last through Wednesday according to NBC10 Chief Meteorologist Glenn "Hurricane" Schwartz.
Isolated storms began to pop up Monday afternoon, including one caught from the air by SkyForce10 over Bucks County and another in Northeast Philadelphia.
A flood advisory was in effect for south central Bucks County, east central Montgomery County and Northeast Philadelphia until 9:15 p.m.
Hot and muggy stays in the forecast through Friday with a possibility of pop-up storms each afternoon.
We can expect a break from the humidity come the weekend.
