Lessons Learned • Frontal passages (esp cold) in the early morning hours lose much of their precipitation (esp in a confluent zone). • It is warmest just before a cold front, including at 5am (relative to normal) • Without organized lifting mechanisms, showers will tend to be widely separated east of the mountains in a southwest flow.
