Discussion

After landfall later today, the remains of “Zeta” will turn northeast and combine with a strong upper-level low to generate a powerful storm system and a significant rain event is coming to the Mid-Atlantic region from tomorrow into early Friday. By late tomorrow night, this powerful storm will likely be situated off the Mid-Atlantic coastline and a cold air mass will begin to get wrapped in. As a result, there is a good chance that some of the higher elevation, interior sections of the Northeast US (e.g., Poconos, Catskills, Hudson Valley) experience a changeover from rain to snow with accumulations certainly on the table. Following the departure of the storm, it’ll turn quite cold on Friday night with the first freeze of the season likely and low temperatures in the upper 20’s. If, in fact, Saturday does bring the first freeze of the season, it’ll actually mark the shortest growing season in some spots since 2002 at 174 days between freezes. On Saturday, temperatures could very well average out to be some fifteen degrees below-normal making for quite a cold time of it for trick-or-treaters as we end the month of October. One final note, this is the weekend to turn the clocks back as of early Sunday morning, November 1st.
