U.S. Weather Bureau Office at Little Rock

From FranaWiki

The U.S. Weather Bureau Office at Little Rock opened on July 1, 1879. During a devastating storm which struck the city's downtown on October 2, 1894 the office recorded the nation's first reliable measurement of barometric pressure change from a direct tornado strike. The funnel of the cyclone may have passed directly over the local U.S. Weather Bureau office occupied by George S. Harkness at 8:28 PM. Harkness recorded a 0.38 inch pressure drop on his Richards barograph machine.
