Vertical Cross-Section through LAPS domain from West to East through Boulder, CO. Terrain is shown in solid red. White areas denote fractional coverage of cloud layers in eighths. Colored areas (if present) denote radar reflectivity. Purple is 0-20 dBz, Green is 20-30 dBz, Blue is 30-40 dBz, Orange is 40-50 dBz, Yellow is 50-60 dBz, Red is > 60 dBz. Symbols '*' and 'R' denote snow and rain, respectively.

Note that the surface reflectivity and surface precip type fields are further processed based on additional data. They may thus be slightly different (and better) than inferring surface conditions from this 3-D graphic.

Wind barbs show wind direction and speed. A barb pointing to the left means the wind is from the west. Each flag is 10 knots (11.5 mph), and half flags are 5 knots.

The coutoured field is temperature in degrees Celsius.
