I think Powderfreak has been writing the BTV discussion:https://forecast.weather.gov/product.php?site=BTV&issuedby=BTV&product=AFD&format=CI&version=1&glossary=1
The biggest change as we enter into the
temporal realm of higher-resolution mesoscale and Convection-
Allowing Models (CAMs) time range has been a delayed onset of
winter precipitation as well as snowfall accumulation. While it
is tempting to use straight 10:1 SLRs or kuchera snowfall
amounts, the fact that we are two weeks after the start of
astronomical spring warrants a closer look at the thermal
profiles. While it is not impossible to accumulate snow at 34
degrees with mesoscale banding, the snow does have to come down
fast and furious in the valley locales. Besides the sun angle,
there is also the potential for a prolonged duration of sleet,
which will significantly cut down snowfall amounts in the
valleys. All things considered, a better proxy for this upcoming
late season winter storm is the positive snow depth change.
While far from perfect, it should provide better context on what
would most likely occur compared to low probability worst case
scenarios depicted by straight 10:1 or kuchera snowfall outputs.
