Narrative:
On descent into pasco (psc) with tower closed, we checked WX with company. The report was similar to our final WX report received prior to leaving slc. They asked for braking action report on taxiway and first officer received no braking action report from company. A few mins later ZSE advised us psc braking action runway fair, txwys poor. This was first indication of other than clear, good braking, because our final WX field report showed 'no report' under field conditions for psc. Landed on runway 21R (winds 230 degrees 30 KTS) and braking was fair to poor. Slowed to a complete stop on runway, then very slowly taxied up to taxiway B. Once on taxiway B the aircraft began to slide sideways with braking action nil. I used #1 engine power to try to bring aircraft back to taxiway center. Aircraft nose moved about 40 degrees to right, but now aircraft started sliding backwards and sideways. Used both engines in varying amounts of power to finally return to center of taxiway, pointed 40 degrees to the right. Set parking brake and called psc operations, dispatcher, ZSE (PIREP) eventually a sand filled truck came out and deposited a lot of sand around aircraft and taxiway. A tug was finally able to hook up and tow us in. Total time from touchdown to block in 1 hour 51 mins. There was no actual taxiway excursion. Somehow the system at our airline broke down concerning field reports. Upon further follow up with dispatcher, I found out psc field reports had expired. Our airline is conducting some follow up with psc airport (why were txwys allowed to get that bad?) and in house to see how field reports were allowed to expire when actual conditions were so poor.

Title: FLC OF B737 IS GIVEN A RPT OF BRAKING ACTION RWY FAIR, TXWYS POOR. ONCE ON TXWY BRAKING ACTION WAS ACTUALLY NIL. LOSS OF ACFT CTL RESULTED AND ACFT WAS STOPPED AND A TOW REQUESTED.
Narrative: ON DSCNT INTO PASCO (PSC) WITH TWR CLOSED, WE CHKED WX WITH COMPANY. THE RPT WAS SIMILAR TO OUR FINAL WX RPT RECEIVED PRIOR TO LEAVING SLC. THEY ASKED FOR BRAKING ACTION RPT ON TXWY AND FO RECEIVED NO BRAKING ACTION RPT FROM COMPANY. A FEW MINS LATER ZSE ADVISED US PSC BRAKING ACTION RWY FAIR, TXWYS POOR. THIS WAS FIRST INDICATION OF OTHER THAN CLR, GOOD BRAKING, BECAUSE OUR FINAL WX FIELD RPT SHOWED 'NO RPT' UNDER FIELD CONDITIONS FOR PSC. LANDED ON RWY 21R (WINDS 230 DEGS 30 KTS) AND BRAKING WAS FAIR TO POOR. SLOWED TO A COMPLETE STOP ON RWY, THEN VERY SLOWLY TAXIED UP TO TXWY B. ONCE ON TXWY B THE ACFT BEGAN TO SLIDE SIDEWAYS WITH BRAKING ACTION NIL. I USED #1 ENG PWR TO TRY TO BRING ACFT BACK TO TXWY CTR. ACFT NOSE MOVED ABOUT 40 DEGS TO R, BUT NOW ACFT STARTED SLIDING BACKWARDS AND SIDEWAYS. USED BOTH ENGS IN VARYING AMOUNTS OF PWR TO FINALLY RETURN TO CTR OF TXWY, POINTED 40 DEGS TO THE R. SET PARKING BRAKE AND CALLED PSC OPS, DISPATCHER, ZSE (PIREP) EVENTUALLY A SAND FILLED TRUCK CAME OUT AND DEPOSITED A LOT OF SAND AROUND ACFT AND TXWY. A TUG WAS FINALLY ABLE TO HOOK UP AND TOW US IN. TOTAL TIME FROM TOUCHDOWN TO BLOCK IN 1 HR 51 MINS. THERE WAS NO ACTUAL TXWY EXCURSION. SOMEHOW THE SYS AT OUR AIRLINE BROKE DOWN CONCERNING FIELD RPTS. UPON FURTHER FOLLOW UP WITH DISPATCHER, I FOUND OUT PSC FIELD RPTS HAD EXPIRED. OUR AIRLINE IS CONDUCTING SOME FOLLOW UP WITH PSC ARPT (WHY WERE TXWYS ALLOWED TO GET THAT BAD?) AND IN HOUSE TO SEE HOW FIELD RPTS WERE ALLOWED TO EXPIRE WHEN ACTUAL CONDITIONS WERE SO POOR.
