Tomorrow’s Outlook: Severe Storms Possible

With a cold front approaching, temperatures will warm up again tomorrow morning, peaking early in the upper 80s to lower 90s inland and in Long Island/S CT, with lower to mid 90s in the immediate NYC area and parts of Long Island closer to NYC. With the cold front, occasional thunderstorms, some of them strong/severe, are expected to affect the area especially after 1 PM. These storms may be capable of producing heavy rain, strong wind gusts and potentially hail. The storms are expected to end in the evening hours with clearing skies and dropping temperatures overnight.

Forecast Overview:

With the cold front moving offshore, mostly to partly sunny skies and temperatures in the lower to mid 80s will return for the weekend. By Monday, however, a strong upper level low will drop into the region as another ridge builds into Canada, once again locking a trough into the region while keeping the heat well to the west. Occasional rain and possibly thunderstorms are expected on Sunday night into Monday, followed by drier conditions for Tuesday and Wednesday with occasional sunshine, a risk of scattered showers, and below average temperatures, only reaching the lower to mid 70s for highs across most of the area. While no significant heat will build into the region, a gradual moderation in temperatures is likely for the second half of next week. Stay tuned for more information on the longer range with tomorrow’s update.
