Upper Midwest and Northeast
Light to moderate flights in the mid Atlantic kicked off Friday night, followed by a pulse of mostly moderate and locally heavy flights in the Midwest for the remainder of the weekend. A similar, albeit less intense example of the same pattern followed on Monday and Tuesday night. With a frontal boundary moving across the region late in the period, a more extensive mostly moderate intensity flight ended the work week; note that most of this movement was south and west of the eastern Great Lakes.

Gulf Coast and Southeast
Locally moderate flights kicked off the weekend, with more intense local flights and more widespread moderate flights arriving by Sunday night in most areas. Intensities of movements dropped significantly during the course of the work week, as southerly flow and warmer temperatures built back into the region. But Thursday night saw a break in these conditions, with the return of more widespread moderate and locally heavy flights in almost all but the most southern reaches of the region.

Great Plains
Locally moderate to heavy pulses were the norm for the entire period across the region. No region wide movements occurred, primarily because of multiple passing disturbance that were neither intense nor extensive in their extents. The heavies flights occurred in the southern Plains, on Sunday, Wednesday and Thursday nights, with Thursday’s flight the most intense in particular over eastern Oklahoma.

West
Aside from the isolated moderate flights in the Pacific Northwest on Friday night, the West experienced a quiet migration weekend. Scattered precipitation and some unfavorable winds kept birds grounded in many areas. Scattered light movements aside, the next more intense flight came in California on Tuesday night reaching moderate levels. Slightly less intense but similarly distributed, more coastal, flights continued through the end of the period, most notably reaching their greatest extents on Thursday night.
