Extended TCF

The Extended Traffic Flow Management (TFM) Convective Forecast (TCF) is a high resolution model blend denoting a high confidence graphical representation of forecasted convection meeting specific criteria of model echo top and convective precipitation fields. The Extended TCF graphics are produced every 2 hours and valid at 2 hour increments from 10 to 30-hours after issuance time. The Extended TCF potential polygons are derived from looking at agreement between the model solutions in a common location.

The Extended TCF domain is the Flight Information Regions (FIR) covering the 48 contiguous states and adjacent coastal waters.
