Narrative:

On climb out from okc to ord we noted an area of rain and cell activity from tulsa north. As we continued to climb the activity began to thin and go below us. We received permission to deviate as needed around the rest, as others in the area had done. Some 30-20 mi short of the area we received a smoke in the forward lavatory alert. I, as PNF, began the procedure for the alert. The alert, after a short period of time, corrected itself, but I still received a no smoke call from the flight attendants. I then returned my attention to the flight in time to notice a cell dead ahead. I instructed my first officer to make a turn to the left to avoid it as much as possible. We skimmed the edge of the cell enough to get some moderate turbulence and rain. Even though all of this happened very fast, I noted the first officer's radar was not showing any WX in front of us at all. His range and tilt were set to a point that he should have painted at least the cell we went around. Shortly after the turn, we lost and could not reset the autothrottles for the remainder of the flight. Next came a short-lived high tgt alert that I believe reset itself. 7 mins or so later came a #2 stabilizer trim failure alert. This we reset and it was fine from that point on. Finally, on final, we lost the first officer's flight director. This reset itself at some point of time by itself. Looking back at this flight, we really only had 1 mechanical failure in my opinion, and that was the WX radar. The autothrottles reset on the ground in a second by maintenance. While all the others came on as spurious ones.

Narrative: ON CLBOUT FROM OKC TO ORD WE NOTED AN AREA OF RAIN AND CELL ACTIVITY FROM TULSA N. AS WE CONTINUED TO CLB THE ACTIVITY BEGAN TO THIN AND GO BELOW US. WE RECEIVED PERMISSION TO DEVIATE AS NEEDED AROUND THE REST, AS OTHERS IN THE AREA HAD DONE. SOME 30-20 MI SHORT OF THE AREA WE RECEIVED A SMOKE IN THE FORWARD LAVATORY ALERT. I, AS PNF, BEGAN THE PROC FOR THE ALERT. THE ALERT, AFTER A SHORT PERIOD OF TIME, CORRECTED ITSELF, BUT I STILL RECEIVED A NO SMOKE CALL FROM THE FLT ATTENDANTS. I THEN RETURNED MY ATTN TO THE FLT IN TIME TO NOTICE A CELL DEAD AHEAD. I INSTRUCTED MY FO TO MAKE A TURN TO THE L TO AVOID IT AS MUCH AS POSSIBLE. WE SKIMMED THE EDGE OF THE CELL ENOUGH TO GET SOME MODERATE TURB AND RAIN. EVEN THOUGH ALL OF THIS HAPPENED VERY FAST, I NOTED THE FO'S RADAR WAS NOT SHOWING ANY WX IN FRONT OF US AT ALL. HIS RANGE AND TILT WERE SET TO A POINT THAT HE SHOULD HAVE PAINTED AT LEAST THE CELL WE WENT AROUND. SHORTLY AFTER THE TURN, WE LOST AND COULD NOT RESET THE AUTOTHROTTLES FOR THE REMAINDER OF THE FLT. NEXT CAME A SHORT-LIVED HIGH TGT ALERT THAT I BELIEVE RESET ITSELF. 7 MINS OR SO LATER CAME A #2 STABILIZER TRIM FAILURE ALERT. THIS WE RESET AND IT WAS FINE FROM THAT POINT ON. FINALLY, ON FINAL, WE LOST THE FO'S FLT DIRECTOR. THIS RESET ITSELF AT SOME POINT OF TIME BY ITSELF. LOOKING BACK AT THIS FLT, WE REALLY ONLY HAD 1 MECHANICAL FAILURE IN MY OPINION, AND THAT WAS THE WX RADAR. THE AUTOTHROTTLES RESET ON THE GND IN A SECOND BY MAINT. WHILE ALL THE OTHERS CAME ON AS SPURIOUS ONES.
