Low pressure west of the Appalachian Mountains on the 23rd underwent secondary development along a baroclinic zone lingering off the Mid Atlantic coast. That secondary area of low pressure steadily deepened as it moved northeastward into the Gulf of Maine by the 24th. Mid level low centers developed in a location that ensured that warm air struggled to get very far north and prevented most of the mixed precipitation potential. That and a cool and dry antecedent air mass meant that the predominate precipitation type was snow across most of western Maine.
