Wednesday June 15 – If you had solid rain this morning, consider yourself in the primed zone. There has been a very narrow band of rain roughly 50 miles wide the extended across central Pennsylvania and Maryland this morning. On either side, it was just spotty or sprinkles. That is moving out, but the atmospheric memory will show this same region set up for the net batch of energy arriving tonight. There will be a line of rain pushing east and southeast.

This should pass over metro Baltimore by midnight, and extend off to Delmarva early Thursday morning.
