Narrative:
Assigned to cross the shonn intersection on the sketr 2 arrival, following approved deviation around thunderstorm over rwf VORTAC. Initiated descent late. Descent was shallow due to power application to monitor anti-icing system. Captain informed center that aircraft would not make crossing restr as published at shonn intersection and requested 'relief.' center replied 'just do the best that you can.' aircraft reached the assigned altitude 3 mi late at the fcm 248 degree radial, 028 DME. As first officer and PF, I should have initiated the descent earlier and monitored it more closely to ensure making the proper crossing restr.

Title: DC9-30 CREW GOT THE ZMP CTLR TO LIFT A XING RESTR THAT THE CREW WAS UNABLE TO MEET DUE TO ICING LIMITATIONS.
Narrative: ASSIGNED TO CROSS THE SHONN INTXN ON THE SKETR 2 ARR, FOLLOWING APPROVED DEV AROUND TSTM OVER RWF VORTAC. INITIATED DSCNT LATE. DSCNT WAS SHALLOW DUE TO PWR APPLICATION TO MONITOR ANTI-ICING SYS. CAPT INFORMED CTR THAT ACFT WOULD NOT MAKE XING RESTR AS PUBLISHED AT SHONN INTXN AND REQUESTED 'RELIEF.' CTR REPLIED 'JUST DO THE BEST THAT YOU CAN.' ACFT REACHED THE ASSIGNED ALT 3 MI LATE AT THE FCM 248 DEG RADIAL, 028 DME. AS FO AND PF, I SHOULD HAVE INITIATED THE DSCNT EARLIER AND MONITORED IT MORE CLOSELY TO ENSURE MAKING THE PROPER XING RESTR.
