I think mother nature is a little confused this time around, but we have to roll with the punches!
From the 70's and severe thunderstorms to the 30's and snow all in a matter of a week! This weekend will be a weekend to make indoor plans and stay out of the elements.
While it is 48 hours before the system, it does look like some of our area will see minor accumulations Sunday morning. Snow that falls before sunrise may stick to some surfaces, though major accumulations are not expected. I'm thinking 1-2" in the central & northern Valley with less than 1" in the southern Valley. Of course this is subject to change as we still have 2 days to see how the system progresses.
I wouldn't cancel plans for Sunday, but I would advise not driving before sunrise. Late March snow systems are completely different than January & February. Why?
#1: Sun angle - we have a stronger sun in late March - that means after sunrise, while it may be snowing, temperatures will have a greater chance of getting above freezing and promote melting.
#2 Warm Surfaces - Keep in mind that temperatures have been well above average for the past 2-3 weeks. It's going to take a lot of time for accumulation to begin and melting will occur even after accumulation begins.
The time frame for this event is 2am-lunch time Sunday, but after sunrise this should be a minor issue.
Stay tuned for updates with Meteorologist Aubrey Urbanowicz this weekend.
