The Center on Budget and Policy Priorities has published State Revenues Plummet:  July-September Revenue Numbers Are Worst in Years, by Nicholas Johnson & Andrew Nicholas:

States are beginning to report revenue collections for the July-September 2008 quarter, and the new figures raise the likelihood that large, additional budget shortfalls are developing. Of 15 mostly large and mid-sized states that have published complete data for this period, the majority collected less total tax revenue in July-September 2008 than was collected in the same period in 2007. … After adjustment for inflation, total revenue collections are below 2007 levels in 14 of the 15 states.
