The strong storm that brought wind-whipped heavy snow to Amarillo, flooding rain from parts of the Gulf states to the Carolinas and an assortment of other ingredients in between is now heading toward the Northeast region. When rain moved into the the higher elevations of western North Carolina this morning, damaging freezing rain broke out in some communities. However, in general, the air mass ahead of this storm is nowhere near as cold as the air masses that were in place for previous storms. Therefore, rain is likely to be dominant through much of Pennsylvania, the lower elevations of New York state and much of central and southern New England.
Once the storm slowly moves away, the Northeast should have an extended period of chilly weather. While not extremely cold, it will become more unseasonable because the long-term average temperatures are trending higher from now into summertime. In parts of the Middle Atlantic states, tomorrow may be about as mild as it gets any time in the next couple of weeks. Later this week, the chilly air mass will be fairly moist, and we may see snow showers lining the Appalachians.

There's a west to northwesterly flow of basically dry air from south-central Canada to the northern part of the Middle Atlantic states. The flow changes orientation farther south. A light northerly flow is helping slightly less humid air to seep southward.
In parts of the Northeast, a sky looking as blue and clear as the one in the picture will be quite a departure from the look of the rainy skies that were much more common earlier in the summer.
The steering winds aloft are changing, and the next phase looks like it will feature a northwesterly flow of cooler air this weekend and much of next week.
It's going to be hot hazy and humid in the much of the Northeast today through Thursday. The recalescent, sudorific, canicular, pyrogenic frying heat gains our attention.
A line of persistent showers and thunderstorms stretched from Long Island Sound to Cape Cod. Some areas in this zone had more than 3 inches of rain this morning, and there can be highway flooding in localized heavy showers this afternoon and evening. This radar shows the rain zone just after 10 a.m. ET.
This map shows the predicted upper-air flow for tomorrow night. Our timing estimates suggest showers and some thunderstorms could affect the I-95 corridor from Portland and Boston to New York City (and perhaps Philadelphia) on Sunday.
