The hot streak of weather for the D.C. region continued on Friday with dangerous heat levels, capped off with some storms that were severe in some parts of the area.
The National Weather Service issued severe thunderstorm warnings as scattered strong to severe thunderstorms formed and drifted into the WTOP listening area just as the rush hour got going.
A severe thunderstorm watch for the listening area ended at 8 p.m.
The heat advisory for Friday was in effect until 7 p.m. for most of the region. The heat index ranged from 105 to 110 degrees during its peak in the afternoon into the early evening hours.
The cold front will bring more showers and storms with potential heavy rain on Saturday into Saturday night, but because of the clouds and the numerous showers, it will stay out of the 90s, so the heat wave will be over.
Northwesterly winds will start to dry us out on Sunday, bringing in not only more seasonable temperatures, but also much more comfortable levels of humidity.
