Upper Midwest and Northeast
A quiet early “spring” weekend in the region saw light to locally moderate flights in the central Mississippi River valley, Ohio River valley, and the northern and central Appalachians. But a strong passing cold front shut down these early movements. Wednesday and Thursday night saw a return of similarly distributed light to locally moderate flights.

West
Local light movements occurred from California through the Desert Southwest to begin the weekend. However, scattered precipitation in many areas quickly quieted these flights. The next round of movement was similarly distributed, occurring on Tuesday night. Some of these flights were more intense, locally moderate in the Desert Southwest. This intensity expanded to additional southern reaches of the region on Wednesday and Thursday nights.
