A surface weather analysis is a type of weather map that depicts positions for high and low-pressure areas, as well as various types of synoptic scale systems such as frontal zones. Isotherms can be drawn on these maps, which are lines of equal temperature. Isotherms are drawn normally as solid lines at a preferred temperature interval. [2]

The first daily weather forecasts were published in The Times in 1861. [16] In the following year a system was introduced of hoisting storm warning cones at the principal ports when a gale was expected. [18] The "Weather Book" which FitzRoy published in 1863 was far in advance of the scientific opinion of the time.
A manual prognostic chart of the weather in the United States 36 hours into the future. Manual prognostic charts depict tropical cyclones, turbulence, weather fronts, rain and snow areas, precipitation type and coverage indicators, as well as centers of high and low pressure. [6]
