Narrative:
Crossing restr issued to cross tammy intersection at and maintain 10000 ft MSL. Aircraft crossed tammy intersection at 14000 ft MSL. Severe thunderstorms and turbulence impeded descent. Crew was distraction by WX, poor radio reception. Additionally, mem active runways reversed while WX active. Landing data recomputation and checklist execution all contributed to crew distraction. Belaying checklists would have helped toward relieving immediate cockpit workload. ATC advised of WX problems. No conflicts noted. Supplemental information from acn 410211: given crossing restr of 10000 ft at tammy intersection on marvel 2 arrival mem. Due to cockpit training going on at flight engineer position (IOE), very busy radio traffic, runway change (runways 18 to runways 36) and WX considerations (cumulo nimbus in area) did not meet restr.

Title: ACR FRT B727 FLC DISTR WITH EXTERNAL AND INTERNAL ACTIVITIES, UNDERSHOT STAR XING RESTR. PIC ALLEGES DISTRS CAUSED BY TRAINING, WX, RWY CHANGE AND CHKLISTS.
Narrative: XING RESTR ISSUED TO CROSS TAMMY INTXN AT AND MAINTAIN 10000 FT MSL. ACFT CROSSED TAMMY INTXN AT 14000 FT MSL. SEVERE TSTMS AND TURB IMPEDED DSCNT. CREW WAS DISTR BY WX, POOR RADIO RECEPTION. ADDITIONALLY, MEM ACTIVE RWYS REVERSED WHILE WX ACTIVE. LNDG DATA RECOMPUTATION AND CHKLIST EXECUTION ALL CONTRIBUTED TO CREW DISTR. BELAYING CHKLISTS WOULD HAVE HELPED TOWARD RELIEVING IMMEDIATE COCKPIT WORKLOAD. ATC ADVISED OF WX PROBS. NO CONFLICTS NOTED. SUPPLEMENTAL INFO FROM ACN 410211: GIVEN XING RESTR OF 10000 FT AT TAMMY INTXN ON MARVEL 2 ARR MEM. DUE TO COCKPIT TRAINING GOING ON AT FE POS (IOE), VERY BUSY RADIO TFC, RWY CHANGE (RWYS 18 TO RWYS 36) AND WX CONSIDERATIONS (CUMULO NIMBUS IN AREA) DID NOT MEET RESTR.
