Extended Forecast: Temperatures will heat up inland early this week, with highs in the 90s and some valleys reaching the low 100s by Tuesday. Along the coast, nights and mornings will bring low clouds and fog, but afternoons should clear out. By midweek, a low-pressure system moving into California will cool things down and increase clouds, with only a very slim chance of rain or an isolated thunderstorm in far southern Mendocino or Lake counties.
