Narrative: Executing ILS Z approach to JAC in actual instrument conditions to minimums. Salt Lake Center cleared us for the approach at IAF Dunoir. Center did not instruct crew to 'contact tower' at any point on the approach. No approach control. Hand off is from center directly to tower. Approach was very challenging in blowing snow; high winds; and icing conditions. Vertical descent profile is significant to effectively and safely descend on published points on the approach. Crew was absorbed in the execution of approach in accordance with AOM and SOP. Achieved position in visual conditions for a safe landing just prior to published approach minimums. At that point crew realized we had not contacted tower for landing clearance. Contacted tower and requested landing clearance. Tower stated to report FAF inbound.  Visibility was reduced and tower could not see us. No radar in tower. Stated we were on short final. Radio became blocked and it is unclear if we ever received landing clearance. After landing; tower instructed crew to taxi to the flight line without further discussion or incident.1. Center instructs 'contact tower' now or at some point on the approach. 2. When tower knows they have an inbound aircraft they reach out to aircraft and establishing communication in low visibility environment; especially with lack of radar in tower.3. Establish an approach control facility in the area of operation.


Second narrative: Flying the ILS Z RWY 19 into JAC we never received a handoff from Salt Lake Center to JAC tower. The weather was such that we were IMC down to minimums and there was trace icing on the aircraft. The approach itself is rather challenging as it is in mountainous terrain and has several altitude restrictions between the IAF and FAF. As a crew we were backing each other up and flew the approach with no issues; but as we approached minimums we realized we had never been handed off to tower and had not spoken to them yet. On short final we contacted the tower and established communication but some transmissions were blocked and we are unsure if the clearance to land was given. Upon landing the tower controller directed us to turn off the runway at A1 and the taxi in was uneventful.Better vigilance on the part of ATC and the crew to establishing communication.


Synopsis: C560 flight crew reports not being handed off by ZLC to JAC Tower during an IMC ILS approach to minimums. The omission is detected by the flight crew and they contact Tower. However; it is not clear if a landing clearance was received due to blocked transmissions.
