i think 8-10 a great forecast for a wide swath south of 78, if you want to account for under or over performance a general 6-12 from north central jersey through middlesex ocean monmouth down to philly
i mean 12-18 was a ridiculous starting point...they could have gone 8-16 or 8-14...all their pinpoints are 14 right now..what model even shows that, even the gfs 10-1 isnt
not just that storm... 40 years of watching these overruning events...thump to sleet to snizzle...the end part usually dry slots and we get less qpf than forecast
the rgem is what I think will happen for me at least
the mix line is way north even at that time so additional accumuations are not that much....a difference of 25 miles is huge for me on the nam vs 3k....10-14 vs 4-6
Enough
I dont have to wait for the Euro
Here is Warlock's first call 54 hours out...and being a first call this will change at least once before final call8-12 inches Central Jersey up to Newark/NYC that could see as little as 6 if sleet mix moves in quicker and if sleet is delayed or never materializes we see the 12-14 inch totals10-14 inches N of 78 to Nw NJ. If sleet reaches these areas could cut down to 8. Colder air could make for high ratios and 16 inch amounts in sweet spots6-9 inches monmouth/ocean/philly/south jersey. Could approach 12 inches if warm nose does not materializeCoastal south jersey 3-6.
