After working in public safety and transportation for almost 20 years, I can tell you that light to moderate snow events are far, far more impactful. Folks see the lane markers and think they can drive like it's dry roads. Nope.
Yup. Rapid onset of an arctic airmass and no wind to wick the surfaces dry. Classic flash freeze.
Agreed. This is probably our best shot for a widespread, warning level snowfall this season. My go/no go would be the 12z runs on Thursday, 1/22. My goal for this window is at least one, widespread warning level snowfall of 6"+. Bonus would be two, warning level snowfalls of 6"+. That would cement the region with it's first above normal snowfall in a decade.
Bottom line: I'm very optimistic about the period Jan 25 - Feb 15.
Radar building across Delmarva and most of the Delaware/Maryland mesonet obs show a NW wind now. Looks like precip should be picking up in intensity for the southern NJ folks here within the hour.
