WEATHER BUREAU

WEATHER BUREAU. Dubuque's first weather observations were made by Dr. Asa HORR beginning on January 22, 1851. Horr measured temperature, humidity, barometric pressure, and precipitation from an observation point at Fifth and Main. He walked outside and measured wind speed with his hand. In 1858 Horr moved his weather gathering operation to Ninth and Main, a location he used for the next thirteen years. He made his last weather observation in 1871.

In 1873 the United States Army Signal Corps established an observation headquarters on the third floor of a building located on the southwest corner of Sixth and Main. The station was manned by Sergeant Robert Bell who began his work on July 10th. Bell was also in charge of daily setting the TOWN CLOCK.

Weather forecasts, expressed as probabilities, were first issued while the observation point was located at Sixth and Main. In 1889 the observatory was moved to Fifth and Main. It remained there until the Panic of 1893 when it was closed as an economy measure.

Until the observatory was re-established four years later, T. W. Reute served as an observer at 568 Main. In 1902 the weather bureau was moved to the old post office building at Ninth and Locust. In 1934 with the completion of the new federal building, the weather bureau was moved again. The weather bureau was moved for the ninth time in 1951. Transferred to the municipal AIRPORT, the bureau was able to coordinate weather and aviation forecasts.
