The national synoptic map is full of weak frontal systems creating a hodgepodge of lackluster weather events. This translates to migration conditions across the country ranging from mediocre to optimal. It’s worth checking out the loop from yesterday afternoon through current time on Paul Hurtado’s NEXRAD archive here. Migration was heaviest in the center of the country, sandwiched by two stationary fronts. Also heavy was the migration over the Upper Midwest, northwest of the stationary front, where winds were more northwesterly and favorable.

The heaviest movement continued to be out of the Upper Midwest where birds could be seen streaming in from Southern Canada down through southwest Iowa. See below for a more detailed look at this region. Continue reading
