Narrative:

Crew departed without weight and balance. Takeoff weight problem. Routinely; this flight has a weight problem operating out of mwcr with B737-400. The flight was weight restr and prior to departure; the passenger restr was lifted; but still restr for cargo. The flight departed; and since the actual temperature was cooler than the planned; I expected the weight problem was resolved with current temperature. I did not receive any information from crew; station; or load planning that the flight needed its revised weights. The flight was airborne; and WX moved into clt area. I checked the revised weights to see if there was open weight; and found there was no revised weights sent. Contacted the load planning agent and asked if flight had received it; and was told that the flight had departed with no final sent to crew. The load planning agent had taken into account the current winds and temperature; and said flight departed 450 pounds overweight. Flight was takeoff restr. Dispatch checking all information regarding the flight; due to WX in clt area and needed to know final weights. Concern for fuel while making a plan if WX delayed arrival into clt. The flight's arrival fuel was planned to be low due to payload. In so doing; dispatch discovered crew never received the final weight and balance. No action required due to flight's takeoff weight being takeoff restr. For my part; should have sent ACARS message to crew to remain on gate till final was received. On the part of the crew; staying on gate when weight is a problem till revised weights is received. On the part of the station; getting information in a timely manner to load planning.

THE FLT WAS WT RESTR AND PRIOR TO DEP; THE PAX RESTR WAS LIFTED; BUT STILL RESTR FOR CARGO. THE FLT DEPARTED; AND SINCE THE ACTUAL TEMP WAS COOLER THAN THE PLANNED; I EXPECTED THE WT PROB WAS RESOLVED WITH CURRENT TEMP. I DID NOT RECEIVE ANY INFO FROM CREW; STATION; OR LOAD PLANNING THAT THE FLT NEEDED ITS REVISED WTS. THE FLT WAS AIRBORNE; AND WX MOVED INTO CLT AREA.

DISPATCH CHKING ALL INFO REGARDING THE FLT; DUE TO WX IN CLT AREA AND NEEDED TO KNOW FINAL WTS. CONCERN FOR FUEL WHILE MAKING A PLAN IF WX DELAYED ARR INTO CLT. THE FLT'S ARR FUEL WAS PLANNED TO BE LOW DUE TO PAYLOAD. IN SO DOING; DISPATCH DISCOVERED CREW NEVER RECEIVED THE FINAL WT AND BAL. NO ACTION REQUIRED DUE TO FLT'S TKOF WT BEING TKOF RESTR. FOR MY PART; SHOULD HAVE SENT ACARS MESSAGE TO CREW TO REMAIN ON GATE TILL FINAL WAS RECEIVED. ON THE PART OF THE CREW; STAYING ON GATE WHEN WT IS A PROB TILL REVISED WTS IS RECEIVED.
