The front comes through on Friday, anything tomorrow would be pre-frontal trough related. Hudson Valley to the CT River will see scattered storms develop during the afternoon, perhaps evolving into multiple lines but there won't be much in the way of west-to-east progression, will be more southwest-to-northeast so probably will see some flash flooding where storms train...probably within the CT River Valley and Naugatuck Valley (should start mentioning them too for future reference because of the rate they flood in these setups).
