With eyes on a weakened Tropical Storm Karen in the Gulf of Mexico, Long Island's weather has slipped into a late summer pattern. Rain from a front, and possibly from Karen, will end this warm spell, as fall weather returns next week.
Humidity remains high into Sunday with highs in the 70s. Low clouds and fog will be around for Sunday and Monday morning. As a cold front approaches from the west, it will hook up with any available moisture from the remnants of Tropical Storm Karen on Monday. This rain approaches Long Island into Monday night and into early Tuesday.
There is the possibility of as much as 1-2 inches of rainfall with the front and Karen's remnants early next week. Where and when exactly is still to be determined, but the possibility, albeit lower than previous forecasts, still exists.
On Monday, skies remain mostly cloudy with highs in the mid 70s. After the rain, humidity drops and skies clear nicely on Tuesday, and for the rest of the week. Highs return to seasonable then, in the 60s to near 70.
While a longshot as of Saturday, tropical moisture on the tail end of the cold front may hook up with a strong tropical flow out in the eastern Atlantic Ocean. There are subtle hints from computer models that this moisture may come into play for Long Island's forecast later next week. On the other hand, a strong high pressure system may keep moisture at bay and out to sea. There are no true 100% indications of anything, so it's "wait-and-see."
