A quick moving storm system brought a warm front north across the region...quickly followed by a cold front. While some gusty winds were reported, the only severe weather was a weak EF0 tornado that occurred in the warm sector behind the warm front. Isolated flash flooding also occurred with the training of rain showers ahead of the cold front.
