March 5 - Inverted Trough/Snow Squalls

Recommended Posts

So it looks like we have an interesting setup for early Monday.  There is a potent s/w diving out of Ontario.  While this is occurring our storm that just exited yesterday will be pinwheeling back an inverted trough.  These 2 will interact with each other and light off a brief but potentially intense bad of snow squalls.

The 1st image shows 850mb level frontogenesis and the 2nd is the 500mb level s/w, that closes off south of us.  Location of the best banding can be difficult to determine at this lead but it's a pretty solid signal for some snow in the air for some.

These usually favor eastern areas and just adjacent inland areas, But try nailing down this even inside 24 hrs can be problematic, Typically these can end up a nowcast type deal.

3k NAM has a decent little band of fronto go through RI before the main inverted trough swings through from NE to SW.

It's not snowing and it's not sleet. It's white mini balls of frozen precipitation. This is what came down at Magic Mtn for a good part of the day. 39/25.

1" at MRG with around 2" at Mt Snow.
