Instructions: Draw isotachs every 20 kts starting at 50 kts (purple line). Draw a red arrow along any jet stream axes.

Instructions: Draw height contours (black-solid line) every 60 gpm (use 5400 gpm as a base). Indicate locations of any troughs using a brown dashed line. Outline areas where the dew-point depression is less than 2°C in green.

Instructions: Draw isobars (black solid line) every 4 mb and temperature (red-dashed line) every 4°C using 0°C isotherm as your base contour. Identify and draw in the fronts for each chart. Include centers of high and low pressure. Surface pressure values are not decoded on the maps.
