Narrative:

We departed the jacky 4 departure from dfw, which is a west departure routing. After takeoff, the WX over the northwest departure gate was severely covered with thunderstorms, all the way to the texas panhandle. Quick thinking was in order because my preflight review of WX had deteriorated rapidly in a short amount of time. We requested a northeast routing. It took ATC a bit of maneuvering to get us over there. We directly overflew dfw to 'get on the other side of dfw arrs.' I handed the first officer the airplane and ATC while I decided to consult with dispatch regarding the WX situation. Again, the WX was worse than I or dispatch had expected. After communicating with dispatch that WX over the northeast of dfw was passable, I assumed PNF duties. We were given climb from 4000 ft to 6000 ft. Because of the high workload situation dealing with WX, talking with flight attendant to remain seated, possible routing changes, many different vectors by ATC, etc, we forgot to climb. A few mins later, I noticed traffic at 12 O'clock position at our altitude via TCASII. I watched traffic and told first officer to expect an RA. We got the RA shortly after that. Since we didn't have traffic in sight, we executed a climb. While waiting to advise ATC, ATC quickly asked us when we were going to climb to 6000 ft. I advised ATC we were now climbing to 6000 ft. We visually acquired traffic and no further conflict arose. The situation arose from many factors: WX that had worsened in a short amount of time, a westerly departure when we really needed an easterly departure, communicating with flight attendant communicating to passenger to remain seated, and conferring with dispatch about WX situation, communicating with first officer about safest route around WX, and making sure deviations would deplete our fuel, etc.

Title: SF340 CAPT BECAME DISTR WITH WX WATCH AND FORGOT TO CLB AS ASSIGNED BY DEP CTL, RESULTING IN TCASII RA WITH ANOTHER ACFT.

Narrative: WE DEPARTED THE JACKY 4 DEP FROM DFW, WHICH IS A W DEP ROUTING. AFTER TKOF, THE WX OVER THE NW DEP GATE WAS SEVERELY COVERED WITH TSTMS, ALL THE WAY TO THE TEXAS PANHANDLE. QUICK THINKING WAS IN ORDER BECAUSE MY PREFLT REVIEW OF WX HAD DETERIORATED RAPIDLY IN A SHORT AMOUNT OF TIME. WE REQUESTED A NE ROUTING. IT TOOK ATC A BIT OF MANEUVERING TO GET US OVER THERE. WE DIRECTLY OVERFLEW DFW TO 'GET ON THE OTHER SIDE OF DFW ARRS.' I HANDED THE FO THE AIRPLANE AND ATC WHILE I DECIDED TO CONSULT WITH DISPATCH REGARDING THE WX SIT. AGAIN, THE WX WAS WORSE THAN I OR DISPATCH HAD EXPECTED. AFTER COMMUNICATING WITH DISPATCH THAT WX OVER THE NE OF DFW WAS PASSABLE, I ASSUMED PNF DUTIES. WE WERE GIVEN CLB FROM 4000 FT TO 6000 FT. BECAUSE OF THE HIGH WORKLOAD SIT DEALING WITH WX, TALKING WITH FLT ATTENDANT TO REMAIN SEATED, POSSIBLE ROUTING CHANGES, MANY DIFFERENT VECTORS BY ATC, ETC, WE FORGOT TO CLB. A FEW MINS LATER, I NOTICED TFC AT 12 O'CLOCK POS AT OUR ALT VIA TCASII. I WATCHED TFC AND TOLD FO TO EXPECT AN RA. WE GOT THE RA SHORTLY AFTER THAT. SINCE WE DIDN'T HAVE TFC IN SIGHT, WE EXECUTED A CLB. WHILE WAITING TO ADVISE ATC, ATC QUICKLY ASKED US WHEN WE WERE GOING TO CLB TO 6000 FT. I ADVISED ATC WE WERE NOW CLBING TO 6000 FT. WE VISUALLY ACQUIRED TFC AND NO FURTHER CONFLICT AROSE. THE SIT AROSE FROM MANY FACTORS: WX THAT HAD WORSENED IN A SHORT AMOUNT OF TIME, A WESTERLY DEP WHEN WE REALLY NEEDED AN EASTERLY DEP, COMMUNICATING WITH FLT ATTENDANT COMMUNICATING TO PAX TO REMAIN SEATED, AND CONFERRING WITH DISPATCH ABOUT WX SIT, COMMUNICATING WITH FO ABOUT SAFEST RTE AROUND WX, AND MAKING SURE DEVS WOULD DEPLETE OUR FUEL, ETC.
