Mount Holly's take on the heat for Friday into the weekend-
Friday through Sunday...The heat is on and will continue through the weekend. Surface high pressure will situate itself over the western Atlantic with a surface trough across the eastern seaboard. In the mid and upper levels, we will see a large ridge spread across the Mid-Atlantic, which will help in facilitating an increasingly hot airmass through the weekend. While the numbers may vary across the models, the 850mb temperatures look to rise around 22-23C each day, which translates to upper 90s to around 100 degrees at the surface, especially for Friday and Saturday. With dew points in the mid to upper 70s, it will feel oppressive and it is looking increasingly likely that heat headlines will be needed for this period. Overnight lows will remain in the upper 70s to around 80, especially through the urban corridor, providing no relief from the heat. The heat starts to break a bit for Sunday as the upper/mid ridge starts to shift towards the east but both the GFS and ECMWF hold onto the higher 850mb values through Sunday so anticipate that the excessive heat will continue through the end of the weekend.
