Narrative:

Holding over sps, in WX, icing conditions. Experienced slow rise in cabin pressure along with flow light. After several mins of troubleshooting, unable to correct problem. Asked ATC for and received a clearance for expedited descent to a lower altitude. In a descending left turn at around 10000 ft, pressure system returned to normal, diverted to okc due to thunderstorms at dfw and pressurization malfunction. Maintenance unable to fix, flew okc-dfw in another aircraft with passenger to dfw.
