Josh Rubenstein's Weather Forecast (July 21)
STUDIO CITY (KCAL9) — It's a decent start to what will be a warm work week. Temperatures will remain on the mild side Monday and Tuesday.
There was only a little bit of low cloud cover Monday morning, but by Tuesday the marine layer will become more organized as the inversion strengthens. However, inland it will start to warm.
A ridge of high pressure located over the four corner states is going to expand and that will bring an extended period of hot temperatures.
Get ready to turn up the furnace for quite a while. Right now it looks like a good five to seven days of extreme heat. Coastal valleys will reach between 100 and 103 while inland valleys will be closer to 107 to 110.
It looks like the high pressure may be able to draw up some monsoonal moisture by next weekend. Right now the best chances for thunderstorm development will be late Saturday into Sunday. Nevertheless get ready for our first big heat wave of the summer.
