Isobars are represented by solid black lines every 4 hPa with the thicker isobars every 16 hPa . You really can't tell, for example, what is causing the cloudy weather with rain (the dot symbols) and drizzle (the comma symbols) in the NE portion of the map above or the rain shower along the Gulf Coast. visible; hence, seen together. Choose a validity time for the surface analysis chart.

Historically, the surface weather map was the first weather map produced, dating back to the early 19th century. Weather maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temperature, and cloud cover onto a geographical map to help find synoptic scale . They display isobars (lines of equal pressure) and indicate areas of high (H) and low pressure (L) along with their central pressure value.
