The TAF or Terminal Aerodrome Forecast product is written to provide the commercial and general aviation industries with forecast surface weather information critical to the safe operation of flights at specific airport terminals. TAFs are issued four times per day, valid for a 24-hour period, and amended as weather conditions dictate. The forecast covers a circle of 5 nautical mile radius centered on the airport or airport runway complex.  A knowledge of the airport operations is necessary to understand the impact of weather on the aviation user community. The Quad-Cities forecast office issues TAFs for four airports in Eastern Iowa/Northwest Illinois.  They are Burlington, Cedar Rapids, Dubuque and Moline.

North Central TWEB routes

TWEBs or Transcribed Weather Broadcasts are route or local vicinity forecasts mainly for VFR general aviation pilots flying generally below 12,000 ft. These products are used for both preflight and en-route planning. TWEBs are recorded for dissemination on various FAA radio frequencies, and some FAA FSSs also use them in briefing pilots. Route forecasts are for a 50-mile wide corridor along a line connecting the anchor points, with a 25 mile radius semi-circle around the end points. Local vicinity forecasts are for an area with a 50 nautical mile radius for metropolitan areas. The local vicinity forecasts prepared by NWSO DVN include CID (305) and MLI (303). Route forecasts include CHI-MLI (217) and CHI-BRL (216). TWEBs are issued four times per day, valid for a 12-hour period, and amended as weather conditions dictate.

All TWEBs can be found at the Aviation Weather Center's TWEB page.
