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. Migration was evident from coast to coast with some of the heaviest migration of the season so far for the Western U.S. The Northeastern U.S. and New England experienced the least migration with suboptimal conditions in terms of winds and atmospheric disturbance prevailing.
