The heat is about to lock in for the new week. First, the near-term concern is reduced visibility from fog for Monday morning.

Fog Possible

Light winds, clear skies, and ample moisture will allow patches of fog to develop. This will be a bigger issue for locations inland of I-95 as winds won’t entirely settle down along the immediate coast.

Fog will dissipate rapidly after sunrise and mainly sunny skies take over for Monday. The heat dome over the Eastern US will allow a hot spell to begin.

Heat

Remember to focus on hydration, do not over-exert outdoors, wear lightweight reflective clothing, and be mindful of heat illness symptoms if they set in for you or someone else. Check on elderly and vulnerable neighbors to make sure they are adequately cooled.

Temperatures Monday will reach into the mid-90s with a heat index of 100°-103°. Temperatures and humidity will both go up a notch for Tuesday and Wednesday. Heat alerts are possible at times this week as heat index values may reach 105°-110° Tuesday through Friday.
