During the afternoon and evening of 5 June 2012, central Montana experienced a rare tornado event for that region, with three confirmed tornadoes from two supercell thunderstorms. While the background environment supporting this event was generally consistent with that corresponding to a severe thunderstorm and tornado event in the mid latitudes, particular factors supporting this event in central Montana were seasonally anomalous. We present climatological anomalies, with mid-level lapse rates and deep moisture content being particularly high for this case. In support of future pattern recognition and forecasting of such an event, for which large potential impact could exist, the synoptic and mesoscale environment evolution, and the radar evolution associated with this event are investigated. Impact-based decision support services and detailed tornado assessments from the National Weather Service in Great Falls will also be discussed.

For accommodations based on disability, or more details, please call 325-6561. All visitors without NOAA or University of Oklahoma identification must register at the registration desk on arrival. Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required.

The University of Oklahoma is a smoke-free / tobacco-free campus.
