Local controller cleared a B727 into position and hold during IMC conditions with a commuter aircraft on final approach for the same runway. After the B727 had already crossed the runway hold line about 20 ft, the controller instructed the aircraft to hold. The B727 flight crew then observed the landing aircraft appear out of the rain and land over them.

Narrative:
Taxiing for takeoff at roc. Current WX: few 700 ft, overcast 7000 ft, 1 3/4 mi visibility, rain/mist. Runway 22 in use. ILS GS OTS. Same controller working ground and tower frequencys! We began our taxi on ground frequency. Approaching the hold short line for runway 22, we switched to tower frequency and advised we were ready for departure. Controller cleared us 'into position and hold runway 22.' I acknowledged 'position and hold runway 22.' both captain and I visually cleared final. Captain called for before takeoff checklist 'below the line' and began to taxi into position and hold. As we were accomplishing the checklist, I overheard another aircraft talking to tower, quickly followed by tower telling us to hold short of runway 22. As tower was telling us now to hold short, I looked out toward final and was surprised to see a commuter aircraft appear out of the rain on short final for runway 22. At the same time, I was telling tower we were already beyond the hold line (by about 20 ft). Captain was applying maximum brakes, but because of our orientation to final and the position of the aircraft on final, he was still unaware of the reason. At this moment, the commuter aircraft crew notified the tower that we were not a factor and continued to land. It appears the roc controller forgot about the commuter aircraft on final when clearing us into position and hold. When controller changed instructions for us to hold short of the runway, we did the best we could to stop. The commuter crew was also heads up and luckily we were able to stop in time to prevent an incident/accident or to cause the commuter to abort its landing.

Title: LCL CTLR CLRED A B727 INTO POS AND HOLD DURING IMC CONDITIONS WITH A COMMUTER ACFT ON FINAL APCH FOR THE SAME RWY. AFTER THE B727 HAD ALREADY CROSSED THE RWY HOLD LINE ABOUT 20 FT, THE CTLR INSTRUCTED THE ACFT TO HOLD. THE B727 FLC THEN OBSERVED THE LNDG ACFT APPEAR OUT OF THE RAIN AND LAND OVER THEM.
Narrative: TAXIING FOR TKOF AT ROC. CURRENT WX: FEW 700 FT, OVCST 7000 FT, 1 3/4 MI VISIBILITY, RAIN/MIST. RWY 22 IN USE. ILS GS OTS. SAME CTLR WORKING GND AND TWR FREQS! WE BEGAN OUR TAXI ON GND FREQ. APCHING THE HOLD SHORT LINE FOR RWY 22, WE SWITCHED TO TWR FREQ AND ADVISED WE WERE READY FOR DEP. CTLR CLRED US 'INTO POS AND HOLD RWY 22.' I ACKNOWLEDGED 'POS AND HOLD RWY 22.' BOTH CAPT AND I VISUALLY CLRED FINAL. CAPT CALLED FOR BEFORE TKOF CHKLIST 'BELOW THE LINE' AND BEGAN TO TAXI INTO POS AND HOLD. AS WE WERE ACCOMPLISHING THE CHKLIST, I OVERHEARD ANOTHER ACFT TALKING TO TWR, QUICKLY FOLLOWED BY TWR TELLING US TO HOLD SHORT OF RWY 22. AS TWR WAS TELLING US NOW TO HOLD SHORT, I LOOKED OUT TOWARD FINAL AND WAS SURPRISED TO SEE A COMMUTER ACFT APPEAR OUT OF THE RAIN ON SHORT FINAL FOR RWY 22. AT THE SAME TIME, I WAS TELLING TWR WE WERE ALREADY BEYOND THE HOLD LINE (BY ABOUT 20 FT). CAPT WAS APPLYING MAX BRAKES, BUT BECAUSE OF OUR ORIENTATION TO FINAL AND THE POS OF THE ACFT ON FINAL, HE WAS STILL UNAWARE OF THE REASON. AT THIS MOMENT, THE COMMUTER ACFT CREW NOTIFIED THE TWR THAT WE WERE NOT A FACTOR AND CONTINUED TO LAND. IT APPEARS THE ROC CTLR FORGOT ABOUT THE COMMUTER ACFT ON FINAL WHEN CLRING US INTO POS AND HOLD. WHEN CTLR CHANGED INSTRUCTIONS FOR US TO HOLD SHORT OF THE RWY, WE DID THE BEST WE COULD TO STOP. THE COMMUTER CREW WAS ALSO HEADS UP AND LUCKILY WE WERE ABLE TO STOP IN TIME TO PREVENT AN INCIDENT/ACCIDENT OR TO CAUSE THE COMMUTER TO ABORT ITS LNDG.
