Narrative:
Lots of thunderstorms around. We were rerouted twice by ATC, from a southern arrival to iad, then up to cvg, then to gso. Last reroute put us into area of WX. As soon as a thunderstorm appeared on radar ahead, I asked ZID for 15 degrees right deviation. Controller said we could not deviate then, but soon. Soon turned out to be later. I told controller we needed to turn in 8 mi, controller refused. Frequency was quite congested. Finally I instructed first officer to tell ATC we were climbing right to 160 degree heading and I avoided top of a TRSA directly in front of us. Controller thanked us for staying near assigned heading. I do not believe there was any traffic alert. Problems: poor planned reroutes, from over arkansas to cvg back to gso, put us into area of WX we should not have been near. ATC overloaded, another aircraft at our altitude too close for either of us to deviate in WX!

Title: AN ACR PIC'S RPT ON PROBS WITH ATC ENRTE PLANNING FOR REROUTES DUE TO SEVERE WX ON A FLT TO IAD, VA.
Narrative: LOTS OF TSTMS AROUND. WE WERE REROUTED TWICE BY ATC, FROM A SOUTHERN ARR TO IAD, THEN UP TO CVG, THEN TO GSO. LAST REROUTE PUT US INTO AREA OF WX. AS SOON AS A TSTM APPEARED ON RADAR AHEAD, I ASKED ZID FOR 15 DEGS R DEV. CTLR SAID WE COULD NOT DEVIATE THEN, BUT SOON. SOON TURNED OUT TO BE LATER. I TOLD CTLR WE NEEDED TO TURN IN 8 MI, CTLR REFUSED. FREQ WAS QUITE CONGESTED. FINALLY I INSTRUCTED FO TO TELL ATC WE WERE CLBING R TO 160 DEG HDG AND I AVOIDED TOP OF A TRSA DIRECTLY IN FRONT OF US. CTLR THANKED US FOR STAYING NEAR ASSIGNED HEADING. I DO NOT BELIEVE THERE WAS ANY TFC ALERT. PROBS: POOR PLANNED REROUTES, FROM OVER ARKANSAS TO CVG BACK TO GSO, PUT US INTO AREA OF WX WE SHOULD NOT HAVE BEEN NEAR. ATC OVERLOADED, ANOTHER ACFT AT OUR ALT TOO CLOSE FOR EITHER OF US TO DEVIATE IN WX!
