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.
This map shows several boundaries, each playing a role in the pattern of showers and/or temperature.
This map shows the pressure analysis for the Northeast and Great Lakes. The gusty flow on the west side of the low pressure area adds a real autumn feel to the air.
Since individual lines and clusters of thunderstorms have limited life spans and change character constantly, forecasting whether it will or won't rain at any one time this weekend is difficult at best. One solution is to have your tablet or phone available with the AccuWeather.com app so you can see where all the storms are at the times when it concerns you the most.
It does look warmer for the weekend, but every time the warm air tries to extend into New England it gets chopped down. There could be more showers at times Sunday and early next week as forest we can tell. If any forecast gives you a headache, why not take a friend's advice: Take two aspen; sequoia in the morning.
This map from 5AM ET shows the cold front that is continuing toward this Northeast and Middle Atlantic states. Temperatures stayed up in the 70s all night ahead of the front but it turned noticeably cooler after the front moved through.
The cold front that will cut off the heat will generate strong gusty thunderstorms as it moves southeastward today. The National Weather Service Storm Prediction Center highlights the most likely area for these severe thunderstorms today and tonight.
As the high pressure area in the Northeast moves away, the the southwesterly flow pattern will shift eastward. This means Wednesday could be the hottest day of the week from D.C. to Boston. A cold front will follow.
