I always read a range as the lower amount is most likely and the highest amount is max potential. Not sure what is confusing about it tbh.

The range is a range...the lowest amount is basically your floor and the highest amount is your ceiling....you can make a caveat and say "isolated amounts up to X inches" if you want to convey a bit more potential....but I don't think anyone has typically forecasted that 3-6" means that 3" is your most likely amount. That means your distribution curve of snowfall is insanely skewed to the left (smaller)...which we know in reality doesn't really happen. Most systems over the long haul will bust high about as often as they bust low.

If most likely is 4", but it could go to 6" (or 7" on the next map), call it 3-6" and just make 1 map

I understand it fine, but for general public it is confusing

Hitting squalls hard

 

 
Snow squall threat. Sheared and stretched impulse through otherwise
cyclonic flow yielding weak surface low pressure along an inverted
trough from the departing Tuesday low. Cold air advection proceeding
through the low- to mid-levels collocated a decent pool of moisture
wrapped back along the inverted trough from Tuesdays low, maintained
by W flow off the Great Lakes. Steepening lapse rates to H6 within
which there is decent W flow around 25 to 35 mph and a fairly moist
0-2 km moist profile with little change in theta-E within the layer.
Instability on the order of 25 j/kg and high total-totals indices
above 50.

No surprise to see the Burlington WRF indicating snow squalls per
associated parameter developing around midday and going through
afternoon. With these squalls can see white-out conditions with the
potential for a quick 1 to 2 inches along with blustery winds and
falling temperatures (near-advisory level).

Threats highlighted within the hazardous weather outlook as there is
confidence of aforementioned impacts. Honestly there is difficulty
in nailing down where this will likely occur and will continue to
monitor high-res guidance. Evaluating precipitable waters, the
better moist profile resides over N/W areas of MA and CT (around
0.25 inches) within the H925-85 layer of better moist convergence /
frontogenesis, while less lift and moisture is apparent S/E. Could
potentially see some narrow-banding.

Keeping consistent with the prior forecaster will keep it likely
PoPs N/W. Everywhere else will speculate there is at least a slight
chance given synoptic conditions which should at least yield snow
showers, potentially near white-out, and coating to 1 inch snow
accumulations. Blustery W winds with temperatures around the mid to
upper 30s.

Qpf with this has been quite limited on all the models so the ceiling is pretty low for higher totals.

They may be a surprise in the IVT though...I could see it happening where someone picks up 8" of fluff. I certainly wouldn't forecast that, but it isn't out of the envelope of realistic outcomes. Coastal Maine might actually have the best chance of a big surprise.

And that is quite possible, Someone pulls .50"+ but that would be in a narrow band if the IVT comes to fruition,  But won't know where that ends up until the event is underway if it happens at all.
