I say go up and take a look. I suspect conditions might be ok, especially if you hit it really early. Bring an alpine rock rack too, and if the ice isn't safe, climb the NE Ridge of Pinnacle or another of the buttresses.
One year on April 30 we climbed Pinnacle Gully in the early AM (started first pitch at 6:00am), and the NE Ridge of Pinnacle later in the day. Conditions had been similar during the week, with warm days but below freezing nights. However, that winter wasn't nearly as warm as this winter. But almost every year someone climbs ice in the Ravines in late October or very early November, when the days are warm but the nights dip below freezing. I don't see why you wouldn't find at least similar conditions this weekend.
Disclaimer: that all assumes safe avy conditions...
