Strong Coastal Storm to Track Up the East Coast Sunday and Monday...Heavy Snow Central PA

A Flash Flood Watch is in effect for nearly the entire New York City tri-state region. As much as 2 to 4 inches with locally higher amounts can be expected. A Severe Thunderstorm Warning is in effect for parts of Central New Jersey until 10:45 p.m. this evening. A Winter Storm Watch is in effect for Central PA for Sunday night and Monday for as much as 8 inches of snow and sleet.  This will cause power outages and numerous down trees and limbs in Jamestown, Bradford and Dubois. A developing storm near Florida this evening will track northward up the coast on Sunday. A very strong upper level trough is digging down across the eastern third of the nation. A 500 mb cutoff low circulation is now tracking across the Gulf of Mexico. This low will combine with a northerly jetstream to produce a large slightly negatively tilted cutoff low by 2 AM Monday morning (in 36 hours). This upper level trough will intensify the surface low over eastern NC and VA and will steer it across eastern PA into central New York State by 8 AM on Tuesday morning (in 66 hours).
