Narrative:

We were flying to jln, mo and were handed off to kansas city center. Center gave us the WX in jln as 25000 thin scattered nd 3 military visibility. We elected to fly straight in for the localizer back course 31. The runway and runway lights were visible from the air and appeared to be slightly obscured by haze and/or fog. When we got about 50 ft off the ground, we encountered thick patchy fog on the runway. I landed the aircraft because I had the landing surface and lights in sight. As we taxied off the runway, it was obvious that the airport was covered with patchy fog. This all happened at xypm. When I called columbia radio to cancel our IFR flight plan, I asked them what the current sequence report was, they said it was 500 overcast and 1/4 mi and fog. Kansas city center either did not give the most current WX or did not have us the current WX. Obviously I could not have initiated the approach with the current WX. There is obviously a time lag when the WX is taken and when it is disseminated to the computer from which center gives it to the pilot.

Title: COMMUTER PIC RPTS UNAUTHORIZED LNDG AT DEST ARPT ACCOUNT BELOW LIMITS. COMPLAINS OF POOR WX RPT RECEIVED FROM ARTCC RADAR CTLR AT CTR.

Narrative: WE WERE FLYING TO JLN, MO AND WERE HANDED OFF TO KANSAS CITY CTR. CTR GAVE US THE WX IN JLN AS 25000 THIN SCATTERED ND 3 MIL VISIBILITY. WE ELECTED TO FLY STRAIGHT IN FOR THE LOC BC 31. THE RWY AND RWY LIGHTS WERE VISIBLE FROM THE AIR AND APPEARED TO BE SLIGHTLY OBSCURED BY HAZE AND/OR FOG. WHEN WE GOT ABOUT 50 FT OFF THE GND, WE ENCOUNTERED THICK PATCHY FOG ON THE RWY. I LANDED THE ACFT BECAUSE I HAD THE LNDG SURFACE AND LIGHTS IN SIGHT. AS WE TAXIED OFF THE RWY, IT WAS OBVIOUS THAT THE ARPT WAS COVERED WITH PATCHY FOG. THIS ALL HAPPENED AT XYPM. WHEN I CALLED COLUMBIA RADIO TO CANCEL OUR IFR FLT PLAN, I ASKED THEM WHAT THE CURRENT SEQUENCE RPT WAS, THEY SAID IT WAS 500 OVCST AND 1/4 MI AND FOG. KANSAS CITY CTR EITHER DID NOT GIVE THE MOST CURRENT WX OR DID NOT HAVE US THE CURRENT WX. OBVIOUSLY I COULD NOT HAVE INITIATED THE APCH WITH THE CURRENT WX. THERE IS OBVIOUSLY A TIME LAG WHEN THE WX IS TAKEN AND WHEN IT IS DISSEMINATED TO THE COMPUTER FROM WHICH CTR GIVES IT TO THE PLT.
