Northeast...
An upper-level trough will dig southeastward across Ontario on
Saturday as a cold front advances southeastward across the
northeastern U.S. A moist airmass is forecast ahead of the front
with surface dewpoints across southeast New York and southern New
England in the mid to upper 60s F. In response, a pocket of moderate
instability is forecast to develop by Saturday afternoon.
Thunderstorms should develop along the front and move
east-southeastward across the region during the early to mid
afternoon. Moderate deep-layer shear, veered low-level flow and
steep low-level lapse rates will be favorable for damaging wind
gusts with the stronger storms. The severe threat should move toward
the New England coastal areas by late afternoon.
