Narrative:
During our flight from den we encountered a thunderstorm that was not painting on our weather radar. We were in a climb; and were down to 130 KTS; and still loosing altitude at 1;000 ft per minute. The weather radar test worked; and we were able to paint ground. The event lasted approximately; 45 seconds. We picked up moderate to severe ice but due to the short duration; it was to no detriment.the weather radar needs to have another way to insure that it is working properly; and adequately. In addition; center gave no indication that we could possibly be flying through that line of thunderstorms. I realize they are not required to; but it would have been nice.
