DVN The first issue is a Clipper system that will affect at least a portion of the forecast area Wednesday night into Thursday. The GFS/GEM continue to be more bullish with QPF than the ECMWF/WRF, which limit most of the snow to north of Interstate 80. Not going to discount the GFS/GEM yet, and have boosted pops/QPF/snowfall from the model blend output. This yields 1-2 inches north of Interstate 80, with a light dusting south. Would not be surprised if we eventually need to consider an advisory with the arctic air in place and SLR`s at or above 20:1. Snow with the first Clipper will likely taper off Thursday evening in the northeast. The next Clipper likely arrives Friday afternoon and evening, with another quick 1-2 inches possible. Consensus pops favor the southwest half of the forecast area for the most snow. Another shot of bitterly cold air will arrive behind this wave, with wind chill values to 25 below zero across the north. For Saturday, the GFS is advertising an third Clipper, while the ECMWF is dry. Have continued low pops for this period. What is more certain is continue cold conditions, with wind chill advisory criteria likely over much if not all of the forecast area Saturday night and again Sunday night.
