The Mixed Surface Analysis map shows a comprehensive analysis of current conditions
and fronts at ground level using radar
and infrared satellite
imagery. The Surface Analysis
loop animation shows sequential maps at 3 hour intervals for the past 18 hours. A surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations. 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 features such as weather fronts.
