Quick 4 AM update on Iota, the rain/wind for tomorrow, potential future snow, and LI forecast:

There is no change in the forecast for Tropical Storm Iota, as it will become a powerful hurricane and make landfall somewhere near the Nicaragua/ Honduras border early next week bringing damaging wind gusts, life-threatening storm surge, and the potential for 20 to 30 inches of rain.

After Iota, no other tropical systems are on the horizon. I wouldn't be surprised though if we get another named storm before the end of the year.

The timing of the rain/wind for Long Island tomorrow afternoon/evening still looks generally on track. It will be interesting to see if the National Weather Service issued a Wind Advisory. As of now, their map is only showing wind gusts up to 32 mph on Long Island, but there will likely be gusts over 40 mph.

The GFS is showing a storm with snow and some sleet for southern New England and Long Island on the Tues/Wed of Thanksgiving week, but it's too early to tell. The GFS snow map is crazy, lol. The odds are still low, but there is a much better chance of snow for the higher elevations of central to northern New England and upstate NY.
