3 Cold Warm Occluded Stationary

4 Winds Southwest Shifting to Northwest after Frontal Passage Weather Thunderstorms Rainshowers Visibility Decreasing Temperature Cooler and drier after frontal passage Rules of Thumb Southwest Wind Cumulus (puffy) clouds Falling Pressures Increasing cloudiness

7 Winds Southeast Shifting to Southwest Weather Rain, Drizzle, Possible Thunderstorm Fog (when ground is cool) Visibility Decreasing Temperature Warm and Moist After Frontal Passage Rules of Thumb Southeast Wind Stratus (flat)clouds) Falling Pressures Increasing cloudiness, low ceilings, slow clearing after passage

8 a Common Warm Frontal Cloud

9 Winds Northeasterly on cold air side, southeast on warm air side Weather Thunderstorm on Cold Air Side Visibility Potentially poor Temperature Minor variations across front Rules of Thumb Persistently poor weather STATIONARY FRONTS CAN LAST FOR DAYS OR WEEKS!!!

10 Winds Southeast to south, after passage West to Northwest Weather Combination of Warm and Cold Fronts Rainshowers, Drizzle, Possible Thunderstorm Fog (when ground is cool) Visibility Poor in precip, improving after passage Temperature Change less significant Rules of Thumb Mixed bag of weather Low Pressures
