... in higher elevations at the end with very cold air behind the storm.***
- Both the HRRR and NAM are showing the potential for rainfall amounts locally over 4 or 5 inches, but the HRRR has it for parts of Long Island and southern New England, while the NAM has it really just for some of the higher elevations, which would cause major problems. Generally though widespread rainfall amounts of 1.5 to 3 inches with higher amounts. I have included 3 wind maps below, and gusts will be strongest for the coast, especially for Long Island and coastal southeastern New England and coastal Maine with max wind gusts of 55 to 65 mph. The wind will be out of the south from the low-level jet ahead of the cold front. There is also a chance of thunderstorms with very heavy downpours. I have included some future radar maps below. I'll have many more posts today with updates on the storm. There will also be significant Lake Effect snow, and I've included the Model Blend snow map below.
- Behind the storm, we have the cold air and then a system for Sunday/Monday with uncertainty in the details, but basically milder with rain for Long Island and there could be some snow much farther north.
