Fireworks viewing away from the coast will be best due to low cloudiness and patchy fog Monday night, according to the National Weather Service.
A gradual warming trend is expected this week through the coming weekend with the warmest temperatures occurring Saturday and Sunday.
Temperatures across inland areas will climb by a few degrees each day, while areas near the coast remain more moderated by marine layer clouds and prolonged onshore flow each morning.
High temperatures on Tuesday were predicted to reach 70 to 75 along the coast, 76 inland, 76 to 81 in the western valleys, 81 to 86 near the foothills, 79 to 88 in the mountains and 100 to 105 in the deserts, according to the weather agency.
The marine layer becomes more shallow starting Thursday, with low clouds struggling to develop away from the immediate coast and some of the coastal valleys by the weekend.
Meteorologists said this will also allow coastal areas to warm up by a few degrees.
