Excessive Rainfall Discussion
NWS Weather Prediction Center College Park MD
304 PM EST Sat Nov 16 2019
 
Day 3
Valid 12Z Mon Nov 18 2019 - 12Z Tue Nov 19 2019 

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

...New England...
Deep moisture and increasing mid level frontogenetic forcing in 
advance of short wave energy crossing New England on Day 3 is 
still expected to produce bands of heavy rainfall, mainly over New 
Hampshire and Maine. As the low level east northeast flow 
increases to greater than 40 knots, there is the potential for 
banded heavy rainfall that results in rainfall amounts in excess 
of 1.50 inches over portions of Maine. 

However, the is little to no instability expected anywhere in the 
column which will keep rainfall rates from supporting a low end 
flash flood threat. This continues to be more of a flood versus 
flash flood threat. Therefore, no excessive area was assigned here 
for Day 3.
