• Precipitation helps lower ceilings

• Occurrence of snow contributes to low visibilities

• Fronts typically enhance precipitation when strong jet dynamics are present

• Fronts cause rapid temperature drops as they pass through

• Light upslope flow leads to low ceilings, low visibility, and lighter precipitation amounts

• Without strong jet dynamics, precipitation tends to be light

• Temperatures do not move very much when there are low clouds
