    3. The cold front now in the middle of the United States will move to the East Coast on Thursday. The upper-air pattern will change quite a bit, and is forecast to look like this on Friday morning. The trough on this map is predicted to strengthen a bit as it comes across the Appalachians on Saturday. Perhaps some showers will break out.

    4. However, this will not be a permanent change to chill. This forecast of the upper-air flow suggests warmer air will be streaming back into the Northeast early next week. This maps shows a forecast of the flow aloft next Monday:

    5. However, most models show that the pattern will be progressive. This suggests that after another round of warming, cooler air will return. Then again, the calendar suggests the same thing.
