It looks like things might be changing. What do u think don
Yep moisture here BUT very cold and only an inch total moisture. Night temps in the teens at 7000 feet next 48 hours.
Snowfall expected 9-18 inches from SAN DIEGO well into Oregon above 6000 feet. (Already snowing in Oregon)
This is a 2 part storm 3-9 inches Tues 19 FEB before the sun comes up and then a repeat 3-9 inches Wed 20 FEB before the sun comes up
Snow levels expected to start at 2500 feet.
Storm center coming thru Fresno with lots of wind.
Okay that was the good.
So it will get real cold and dump very dry powder with high winds. Hope it sticks somewhere but usually this kind of dry snow fall just blows away.
On the good side this may be the start of a new cycle with a storm every 7-10 days?
