.UPDATE...

Latest short term guidance continues to show two-pronged event
affecting southern WI from late afternoon Saturday through Sunday.
Strong low to mid-level warm air advection over baroclinic zone
draped across southern WI will result in strong lift Saturday
night into Sunday. Layer Q-vector convergence increases to 10 to
20 units at 850-700H and NAM cross-sections are showing increasing
frontogenetical forcing in good Dendritic Growth Zone later
Saturday night into Sunday morning. Latest NAM showing 24 hour QPF
valid 00Z.12 around 0.8 tenths. Short wave trof and passing low
pressure will continue to generate snow across the area later
Sunday into Sunday evening. Per coordination with neighboring
offices, will post Winter Storm Watch for our western CWA
beginning late afternoon Saturday, and across eastern CWA
beginning 00Z.Sun. Thinking snow fall amounts by 06Z.Mon likely to
be in the 6 to 10 inch range across southern WI. Breezy se winds
will cause some drifting on Sunday and again late Sunday night
into Monday. Perhaps a period of some blowing snow early Monday
morning.

Getting mixed signals on potential for some lake enhancement in the
east on Sunday. Will watch that closely.
