Upper Midwest and Northeast
Moderate to heavy movements kicked off the period in the Midwest, while the remainder of the region was mostly quiet. But Monday night saw more widespread moderate flights as more favorable conditions for migration spread across the region. This intensity of movement continued, but became increasingly restricted to the Appalachians and Atlantic Coast by Wednesday night as a significant disturbance moved through the Upper Midwest. With unsettled weather still spread across the region, the period ended with a similar spread variety of migration intensities, the highest of which were in the Upper Midwest and mid Atlantic states.

Gulf Coast and Southeast
Increasing but still scattered light to moderate flights started the period. But with the arrival of more favorable migration conditions on Sunday and Monday nights, more intense movements took flight including heavy to very heavy movements between the Mississippi River Valley and the southern Appalachians. Following these large movements intensities waned, despite maintaining their more regional extents, for the remainder of the work week. Generally, the southern Appalachians continued to be the most active areas to end the period.

Great Plains
A moderate to heavy flight night on Friday and a locally heavy northern Plains flight onSunday were the highlights of the weekend. Locally moderate to heavy flights punctuated the work week, but scattered precipitation that was party to an unsettled atmospheric scene kept movements from reaching regional or even sub-regional extents.

Light to moderate flights were apparent across the region for much of the weekend. This was particularly true for the Central Valley of California, the area around the Great Salt Lake, and parts of the Pacific Northwest and northern Rockies. By the beginning of the work week, intensities and extents of migration had decreased, with most of the action along the Pacific Coast for the remainder of the period. This included nice flights in the Pacific Northwest on Tuesday night and in California on Wednesday and Thursday nights.
