Upper Midwest and Northeast
The period began with local light to moderate flights along the coast, and to some extent over New York and New England, while the remainder of the region remained generally quiet. With the arrival and passage of a cold front on Monday night, light to moderate flights began anew in the Upper Midwest. These intensified and grew more extensive by Tuesday night, but their intensity and extent stopped at the Appalachians. The period ended with a similar quiet to its start, with only locally light to moderate flights but this time in the Upper Midwest.

Great Plains
Locally moderate to heavy flights kicked off the period in the southern Plains, diminishing rapidly by Saturday night; however, the remainder of the region was quiet. With the passage of low pressure on Monday came a pulse of light and moderate flights in the northern and central Plains, followed on Tuesday night by a more intense flight in the central and southern Plains. Wednesday saw a movement very similar in intensity and extent to the weekend’s kickoff flight in the southern Plains, and the period ended with local light and isolated moderate flights across the region.

West
The period was generally quiet from a migration perspective. California, portions of the Pacific Northwest, and portions of the Desert Southwest were the only areas that saw action, and even this was restricted mostly to a few nights of the period. The most regular and intense flights occurred in California, with the Central Valley experiencing locally moderate flights on most nights.
