Weather Discussion for Saturday December 8, 2018

Normal high/ low temperatures for Dec 3-Dec 10  (high/low) Redding 57/38, Chico 57/37, Quincy 47/25, Chester 44/22, Susanville 44/23, Grass Valley 53/32, Weaverville 47/29, Mt. Shasta 45/27, Yreka 46/26, Alturas 44/18

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.

We will be under a weather pattern like the one shown on the map below for the next week.  The jetstream will bring low pressure troughs and frontal systems rapidly across the Pacific and then as they reach the coast they will be pulled northeastward and weakened.  This means the systems passing across Northern California will be fast moving and relatively weak.  

Today we will have partly cloudy to cloudy skies.   The next storm will move through Sunday afternoon and early Monday with light rain or showers.  Snow levels will be 4000 to 5000 feet.  Monday will be a break and then a weak system will bring light rain to the coast range, the northern mountains, the valley north of Red Bluff, and the Sierra Cascade north of Plumas county.  Snow levels will be 5000 to 6000 feet.

Thursday afternoon and Friday a slightly stronger system will bring rain to all of the north state with snow levels near 4000 feet.   The next storm will move into the area late Saturday and Sunday.

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.

***Updated at 1000 to put better map and satellite picture***

The low pressure area off the coast has spread clouds and light showers over Northern California.   The low will move inland later today over Central and Southern California.   The north state will have scattered showers through this evening with the snow level near 3000 feet.  

A weak high pressure ridge will keep things partly to mostly sunny Thursday and most of Friday.   Saturday we will see a few clouds from a weak frontal system and there could be isolated light showers north of Redding.  Sunday and Monday a stronger low pressure trough will move through (see map below).  Northern California will have light rain Sunday afternoon and Monday with snow levels 3000 to 4000 feet.  

Skies will clear Tuesday and Wednesday and then another low pressure trough will move through Thursday and Friday.

The precipitation will turn to showers late Thursday morning and then taper off during the afternoon.  A colder low pressure area will move into the area late Friday and Saturday (see map below).  This system  will bring rain to all of the north state with snow levels 3000 feet north and 4500 feet south. 

The rain will end by Saturday afternoon and evening and skies will be partly sunny to partly cloudy Sunday and Monday.  Another low pressure area will move into our area Tuesday and Wednesday for more rain.

Weather Discussion for Monday November 26, 2018

Normal high/ low temperatures for Nov 26-Dec 3  (high/low) Redding 58/39, Chico 59/38, Quincy 49/26, Chester 46/24, Susanville 47/25, Grass Valley 56/34, Weaverville 51/31, Mt. Shasta 47/27, Yreka 48/27, Alturas 47/21

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 low pressure trough has developed in the Gulf of Alaska and is moving eastward.   The trough has generated several frontal systems which will pass through Northern California Tuesday through Thursday.   The first of these systems will move through Tuesday with rain and gusty south winds.  Snow levels will be 5000 to 6000 feet.  The precipitation will turn to showers Tuesday night.  The next system moves through Wednesday and early Thursday with more rain and gusty south winds.  The snow level will be a little lower...4000 feet in the north and 5000 feet south.  Thursday afternoon the rain turns to scattered showers. 

Friday there will be a break between storms and the north state will be partly cloudy to  partly sunny.  A colder low pressure area will move through our area Saturday (see map below).  This system will bring more rain and gusty winds.  Snow levels will be 3000 feet north and 4000 feet south.  Sunday and Monday a weak high pressure ridge will bring drying to the north state.
