DISCUSSION

KEY MESSAGE 1
Following a cold frontal passage this morning, dry and seasonable conditions will be on tap through Tuesday. Aloft, the westerlies will dominate the northern two thirds of the country with a broad upper trough from the Northern Plains all the way to the eastern seaboard. This will allow for cooler temperatures. At the surface, weak high pressure builds east through Tuesday, then offshore later in the day. Gusty NW winds this morning will fall by afternoon. A return southerly flow sets up Tuesday afternoon.

KEY MESSAGE 2
High astronomical tides due to the recent new moon will gradually fall off through midweek. However, water levels will be close to minor coastal flood benchmarks during the nighttime high tide cycles for the more vulnerable locations of the south shore of Nassau, coastal Fairfield, and portions of coastal NJ.
Without much wind forcing, expect this to mainly be statement worthy.

KEY MESSAGE 3
Warm advection showers, possibly a thunderstorm, will be on tap for Wednesday. Best chance will be from NYC and points north and west. Temperatures remain seasonable, but humidity will be on the increase in a southerly flow.

A strong low pressure system may develop over the center of the country and approach from the west later Wednesday night into Thursday. SPC has portions of the area on Thursday (Day 5) with a 15% chance of severe weather. Details regarding this possible system will come into focus in the coming days.
