"Slight cooling will occur for late in the work week, then another warming trend will likely develop over the weekend," forecasters said.

Highs are expected to be in the mid 80s in the valleys and in the mid 90s near the foothills Friday, according to forecasters. It will be foggy in the morning and breezy in the afternoon.

A heat advisory has been issued for mountain communities until 8 p.m. Monday. Temperatures are expected to be in the high 90s Friday, Saturday and Sunday.

In the desert, highs will be in the triple digits and reach 110 in some areas.

In areas under the threat of excessive heat, forecasters repeated their standard warning for people to be on the lookout for signs of heat illness, particularly in "the very young, the very old, those without air conditioning and those active outdoors."
