Weather Discussion for Saturday June 30, 2018

Normal high and low temperatures for June 25-July 2  (high/low) Redding 96/64, Chico 93/58, Quincy 86/43, Chester 81/43, Susanville 85/48, Grass Valley 84/54, Weaverville 90/47, Mt. Shasta 81/49, Yreka 86/49, Alturas 83/42

This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring.

A large high pressure area is currently over most of the U.S. with another high pressure area off the coast.  This pattern will hold through Monday.   During this time Northern California will see clear skies with daytime temperatures 8 to 12 degrees above normal.  Strong gusty north winds will occur through midday Sunday with light moderate north winds through Monday.  

Tuesday a weak closed low pressure area will form off the coast between the 2 highs (see map below).   This system will linger off the coast through Friday and then weaken and move northeastward.   At this time it looks like the main affect this system will have on our weather is to cool temperatures back to normal or a little below.  There could be some isolated afternoon and evening thunderstorms over the mountains north and east of the valley Tuesday through Friday.   If the low was to move closer the thunderstorms will be more widespread.  

Next weekend the high pressure ridge that is over the U.S. will push back to the west and this will bring back the hot weather to the north state.
