Weather Discussion; The Old Forecaster

Chris Fontana, "The Old Forecaster" 4/19/2014

Normal high and low temperatures for this week April 14-April 20 (high/low)...Redding/Red Bluff 70/47, Chico 73/44, Quincy 64/32, Chester 57/28, Susanville 62/34, Grass Valley 61/39, Weaverville 67/35, Mt. Shasta 59/34, Yreka 64/34 and Alturas 60/30.

High pressure is still along the coast and this forcing low pressure troughs and frontal systems to  our north.   Today and Sunday  most of the north state will be sunny with a few high clouds.  The exception will be the north coast and counties along the Oregon Border, which will become partly cloudy this afternoon as a frontal system moves through Washington and Oregon.  Temperatures today and Sunday and will continue 5 to 10 degrees above normal.

A big change in our weather begins Monday when a cold low pressure trough drops southward from the Gulf of Alaska toward Northern California.  This system will move across our area Tuesday (see map below).   The low will bring scattered showers to Northern California Monday and Tuesday with thunderstorms possible Tuesday.  Colder air will move into the state and by Tuesday snow levels will be down to 4000 to 5000 feet. Precipitation amounts will be light.  Gusty southwest to northwest winds will occur Monday afternoon and Tuesday.

The showers will end over most areas by early Wednesday, with decreasing clouds during the day.  Thursday the north state will be partly to mostly sunny with temperatures back to near normal.

Friday and Saturday a stronger....windier and wetter system will move into Northern California.  Light rain is  expected Friday with heavier rain and stronger winds Saturday.   It looks like this will be first of several storms with wet weather through the end of the month.
