Weather Discussion for Monday March 19, 2018

Normal high and low temperatures for March 18-March 25  (high/low) Redding 66/43, Chico 66/41, Quincy 58/30, Chester 53/27, Susanville 55/30, Grass Valley 59/37, Weaverville 61/32, Mt. Shasta 56/ 32, Yreka 58/31 Alturas 55/26

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.

This morning's satellite picture (below) shows a large low pressure area to our west.  This system is moving slowly eastward and will move across Northern California Tuesday and Wednesday.  A colder low pressure trough will drop southward from the Gulf of Alaska and be along the coast Thursday afternoon and Friday (see map below) and will move across the north state Saturday. 

Clouds will increase tonight with rain Tuesday through Wednesday evening.  Wednesday night and part of Thursday we will have scattered showers and then more rain Thursday night and Friday with showers on Saturday.  The first storm is warm so snow levels will start out at 5000 feet and rise to above 6000 feet.  The second storm is cold so snow levels will start dropping Thursday and be down to around 3000 feet by Thursday afternoon and Friday. 

Late Sunday and Monday a frontal system will brush the north state with showers mainly over the higher elevations.
