The National Weather Service has issued Red Flag Warnings for the mountains today due to the threat of dry lightning from isolated thunderstorms.  Valley highs will also warm to well over 100 degrees.

RED FLAG WARNING

We are expecting valley highs to fall 3-5 degrees compared to Monday afternoon, but still well over 100.

A trough of low pressure off to the northwest will also help to pump some mid level moisture over the Northstate.  This moisture plus the heat, may destabilize the environment enough for some isolated mountain thunderstorms.

Cloud bases will be elevated and most of the rain will evaporate before reaching the ground.  So the threat for dry lightning will be around late this afternoon and evening.

Valley highs will fall to near 100 degrees Wednesday.

After hovering in the mid 90s to 100 degrees Wednesday - Saturday, the valley will warm back up Sunday into next week.  We will also have to start to watch the monsoon by the middle of next week.
