And the watches  begin

URGENT - WINTER WEATHER MESSAGE
National Weather Service Quad Cities IA IL
1035 AM CST Sun Feb 23 2020

...HEAVY SNOW POSSIBLE MONDAY NIGHT THROUGH EARLY WEDNESDAY...

.A slow moving winter storm system moving out of the southern
plains is expected to bring snow across eastern Iowa and
northwest Illinois Monday night, which will continue through
Tuesday night. Precipitation will start out as rain during the
day Monday which will change to snow Monday evening. Snow may be
moderate to heavy at times, especially Tuesday through Tuesday
night. Increasing north to northwest winds may cause blowing and
drifting snow Tuesday night into Wednesday morning.

The storm has the potential to be one of the strongest winter
storms of the season so far. While it is too soon to determine
specific snowfall amounts, there is above average confidence that
this system will produce heavy snowfall amounts over portions of
the watch area.

With the standard many ways to underperform and disappoint, I like the potential for an over performer. Long duration, with ratios being notoriously difficult to get accurately. With this much qpf, a 10:1 will be a substantial ground level difference over 6-7:1

I’ll say one thing, being on the west side of Lake Michigan from an incoming classic winter storm track is definitely one of the best ways to get a really good snowfall. I just hope to dear God that this doesn’t all come crashing down on Monday.

If its too soon to determine snow amts its too soon for a WSW. Why not issue them tomorrow after 12Z runs to see if it holds up then warnings Monday evening or early Tuesday?
