Temperatures will soar past 90 degrees this afternoon and tomorrow in much of the I-95 corridor from D.C. to near Boston. The chance for thunderstorms will increase from west to east on Sunday as a cold front from the middle of the country approaches. Some of the storms from northern Virginia to Maine could be severe Sunday afternoon. Once the front goes by, temperatures will trend down.

Today's Chicago area video:
A south to southwest flow of warm humid air controls all of the Great Lakes and Northeast regions.
The first of two pulses of cooler air will arrive in the I-95 corridor with some showers this afternoon (this is separate from the rain that affected eastern New England this morning). This map shows where showers were occurring at 9:30 a.m. ET.
This map shows the predicted upper air flow for Saturday. Chilly air from west-central Canada will have a clear path to the Middle and North Atlantic states. However, another warmup seems likely as we go through next week.
A cold front that will cross the Northeast and Middle Atlantic states this afternoon and evening will trigger showers and, in some places, a thunderstorm. Once the front is offshore, a high pressure area from the Midwest will take over for the weekend.
This map shows the high pressure area that is promoting cool, dry weather in the Northeast today. The low pressure area on the left side of the map is associated with a cold front that will send showers eastward tomorrow.
With fine weather likely on most of the days ahead through early next week, leaf viewing will be a cool experience for many, especially in areas highlighted on this map showing the typical progression of peak fall colors:
This map is a forecast of the upper air flow early on Saturday, Oct. 16. It shows a mild to warm pattern for the Great Lakes and Northeast. The second map is for two weeks from today. Northern snow showers, anyone?
