I mean there's got to be something in this about saturating the column, dendritic growth zones, and whatnot. Hoping for some strong ratios.
KLOT kind of eluded to quicker onset:
Radar shows virga has overspread northern IL and northwest IN
with very slow top down saturation noted as a closing "donut
hole" on our WSR-88D. This top down saturation process should
continue through the day with some light snow likely to
eventually develop from west to east across the area this
afternoon. It`s possible this process may be a tad quicker than
progged in current pops, so may eventually need to tweak the
timing up a bit. Initially, snow should be very small flake size
which should be very slow to accumulate.
