The 850 MB chart is especially useful in the winter in determining precipitation type and is helpful in the summer in locating low-level jet streams and low-level temperature advection. The solid blue line indicates 0ºC, with red isotherms from -2 to -8º C. Hashed white, to magenta, to black areas indicate saturated or nearly-saturated areas.
