The video explores how the weather should unfold this weekend and early next week. While longer-range models show cold air building in Canada and moving south later next week, no snow or freezing weather is in the forecast for the Northeast for the next 10 days.
Nadine has been a fixture over various parts of the open Atlantic for weeks now, and it is likely to still be on the map at the start of October.
Note how the satellite coverage ends over the eastern Atlantic. The satellite that had monitored much of the U.S. and Atlantic Ocean malfunctioned earlier this week. The geostationary satellite that had been monitoring the western U.S. and the Pacific was moved east to make up for some of the lost coverage, but you can see the eastern edge of its picture taking ability from its newest location.
All foliage colors have peaked across much of the interior sections of New York and New England, but this weekend will offer plenty of dazzling color farther south. This barn and wooded hillside scene was photographed 4 miles west of State College, Pennsylvania, this week.
A storm strengthening off the Middle Atlantic coast will cause episodes of rain and cool gusty winds from Maryland to Maine. The heaviest rain today is focused on the Washington, D.C., to New York City area. Later tonight and tomorrow, the heaviest rain and strongest winds (gusts of 30-40 mph) should spread northeastward across New England. As the storm slowly departs, the weather will improve from southwest to northeast. This map shows the circulation around the storm as of 9 a.m. ET.
The reason for this is a growing and then stalling storm aloft. This map shows the predicted circulation around the storm on Wednesday evening, showing how the moisture could keep going round and round until the storm leaves.
This mornng, showers were moving across the lower Great Lakes region. A band of thunderstorms developed near Chicago before 6:30 a.m. CT and reached the southwest Michigan shoreline an hour later (8:30 a.m. ET). The following maps show the shower zone and Chicago area lightning.
The tropics have been more active recently. This map shows various entities that area being tracked and analyzed. Hurricane Gonzalo stands out clearly.
A couple of days ago, the storm entering the East had a stronger circulation than it does now. Here is the pressure analysis from earlier this morning. Several minor disturbance can be seen, and trough lines representing those have been sketched on the map. Note that there is little difference in temperature from western Pennsylvania to Wisconsin.
