Excessive Rainfall Discussion
NWS Weather Prediction Center College Park MD
856 PM EDT Fri Apr 11 2025

Day 1
Valid 01Z Sat Apr 12 2025 - 12Z Sat Apr 12 2025

The probability of rainfall exceeding flash flood guidance is less
than 5 percent.

....Mid Atlantic to Southern New England...
Large area of moderate to occasionally heavy rainfall continues
along the mid-level deformation axis/backside of the Cold Conveyor
Belt (CCB). However, given the lack of instability, rainfall rates
are really struggling to get over 0.35"/hr. Given these hourly
rainfall rates well under 1"/hr, any short-term runoff issues would
be at worst confined to poor drainage locations.
