The hot temperatures, along with continuing gusty winds through the week will lead to an increased risk of fire danger.

There is also the potential for an increase in heat-related illnesses.

Officials suggest drinking plenty of fluids and checking up on relatives and neighbors.

Cooler conditions are expected on Saturday, with temperatures dropping significantly by Sunday.

A storm system may even make its way into the region Sunday night and bring showers into Monday morning.
