Tuesday 9 a.m.
In today's video, we look at the forecast for the rest of the week and the Labor Day weekend.
In Philadelphia and New York City, the greatest chances of rain appear to be today, Sunday and Monday. Temperatures are likely to be in the 80s each day with nighttime temperatures mostly in the 70s. Philadelphia, Baltimore and Washington will have locally flooding downpours today. There is less chance of this in New York City and on northeast from there.
From Boston to Portland, it will be humid but not as warm, with days mostly in the 70s and nights in the 60s. There is little sign of rain on the way to either of those places today, though some showers may pop up this afternoon.
In Chicago, where it reached the mid-90s yesterday, today will be 10-15 degrees cooler. Temperatures will be in the 80s tomorrow afternoon, then near or just past 90 Friday through Sunday. Labor Day itself looks to be dry and cooler from this distance out.

A large high pressure area centered just south of Chicago will furnish a northwesterly of pleasantly cool and dry air to the eastern Great Lakes and all of the Northeast today into Tuesday.
As the trough moves through each locality, warm humid weather will be followed by showers and thunderstorms, then cooler an drier air will arrive
D actually makes up the largest part of this map and represents the large area that is sunny for the most part
The map shows three areas of more concentrated shower activity...
