The heat wave over the last two weeks of August and the first nine days of September had students and teachers sweltering in their classrooms. Boulder was breaking or tying temperature records day after day. Seven of the first nine days in September had highs in the 90s…Jennifer Francis, a research scientist at the Institute of Marine and Coastal Sciences at Rutgers University, surmises that this outlandish rain was the result of a split jet stream. In an NPR interview Sept. 25, she said, "High up in the atmosphere, one stream was carrying moist air from the Pacific to the Rockies. Then, lower down, an unusual eddy was pulling in more moist air from the Gulf of Mexico. Finally, an unusual bulge in the jet streams was causing all this weather to stall near Boulder."
