Eastbound Thunderstorms: Chicago Today, Boston Sunday

September 19, 2013; 6:45 AM ET

Thursday 10 a.m.

A high pressure area off the East Coast will promote increasing warmth over the Northeast for the last few days of summer. A slow-moving, shower- and thunderstorm-producing system from the Midwest should cross the Appalachians on Saturday then affect the I-95 corridor Saturday night into Sunday. After that, there is quite a bit of uncertainty. Earlier, computer models had show a storm developing the Middle Atlantic states, but last night's runs suggest that a new cool high pressure area will move into bring dry weather to the Northeast early next week. Here is the video, and it includes the dry idea for early next week.

A large and dangerous typhoon (Super Typhoon Usagi) is on a course that could bring it into China not far from Hong Kong between Sunday and Monday. A track farther south than the one we currently project would be more troublesome for low-lying areas of the big city because there would be a greater chance for a strong storm surge from the resulting easterly winds. When storms track west and do not curve around to the north and northeast, we often see a ridge aloft over the East seven to 10 days later. In this case, there may be other typhoons in the overall pattern, so any one signal from one storm may not be reliable.
