I'm still leaning toward a warmer solution, along the lines of Upton's current map. The NAM, HREF, and even extended HRRR have fared well in sizing up mid-level WAA this season. Since they all introduce mixing into the interior, and given what we know about SWFEs in general, I think expectations should be tempered. The upside is that rates will be good to start out - that's a solid NW-SE fgn signature coinciding with the best upper-air support. Even where changeover is delayed/avoided, though, ratios will get progressively worse as the event wears on, with moisture becoming shallower and riming more prolific.
Could be a fun event for many, but nobody in this subforum should be expecting a blockbuster.
