Algorithm GFS 00Z GFS 12Z
Identification of Surface Fronts - FRONT.CMD
FRONT helps to identify surface fronts in subtropical and extra tropical locations. Highlights the positions surface fronts based on horizontal gradients of thickness and dewpoint in the lower troposphere, and precipitable water to a lesser extent. If present, surface fronts are usually positioned in the warm edge of the gradient (thick black contours).

Note: These algorithms are only forecast tools, not official forecasts.
