It’s probably a little too early in the evening to tell how things are going to shake out tonight, as there’s rain in the picture already. Not long after taking off, some birds are probably being put back on the ground by a line of rain pushing east through Connecticut and, eventually, through western Mass, then later, Rhode Island. It’s possible that for eastern swaths of the region, this band of rain will have the effect of letting birds leave, but blocking some from arriving. It may also create light fallout conditions through the region, but my prediction would be that more fallout will occur in the areas where birds run into the rain coming from the south and later tonight, that will be Connecticut. The movement out of Jersey has been lighter than in the past few days, so that event may not manifest itself either. These kinds of evenings can be the trickiest to evaluate.
All of this said, it’s still early. I think for tomorrow, the maxim that rain and birds can produce some concentrations if the right conditions occur holds very well, so it’s worth checking your concentration points, like those that fared well on Saturday morning when the combo of rain and birds was just right (at least for Rhode Island).
