Summary of Early Weather
•East of the Cyclone: widespread clouds and precipitations to
the north of the warm
front in the forms of rain, freezing rain, and/or snow.
•South of the Cyclone: a line of showers or thunderstorms forms
along the leading
eastern-most boundary, which could be the upper-level front, dry line, or a cold front.
•These two precipitation centers (east and south) form a “Comma”
cloud.
•Northwest of the Cyclone: Snow forms along the up-slope
side of the Rockies.
