The computer models all show a precipitation-producing feature affecting areas over or near the Middle Atlantic coast late tonight (1 a.m. to 7 a.m. period), but they differ from each other in important ways. This is really a time when you should plan to check back on accuweather.com a number of times as you go through the weekend. Here is the European model's take on this.
The GFS has the same features but is farther along than the Euro. The Euro showed some enhanced precipitation in New Jersey and New York City during this period, while the GFS has the same thing in southern New England.
The NAM seems to have the same timing as the European model but is lighter and less extensive with the precipitation:
The current maps with precipitation areas give few clues about which model will be best.
If correct, cooler, drier and more comfortable weather will take over in the Northeast as we go into the holiday weekend, then warmth and humidity would increase as we go through next week. This map matches that scenario.
that short wave is what the models latch onto in bringing a cold front through the Northeast Wednesday night and Thursday. This would bring noticeable cooling to the Northeast late in the week.
Labor Day is a week from Monday. The computer model used here, the GFS ensemble mean, suggests the weather will favor outdoor late summer activities across the Great Lakes and Northeast:
In response to heating at ground level and a weak cold front approaching from the west, showers and locally strong thunderstorms should develop across northern Ohio this afternoon.
... much greater interest is being generated on threats and rumors about tropical storms. It is worthwhile to read Dan Kottlowski's authoritative reports on this. Here is a copy of his map from this morning:
The tropical Atlantic shows signs of life in the storm development department. Dan Kottlowski's expert discussion suggests the third storm (which could be Hermine) of current concern is one that could head to the Bahamas, Florida, the Gulf or ???
