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.
...after all that, the point is that zone will be north of most of the eastern half of the country. It will be very warm to hot south of the jet stream. However, weakening cold fronts can advance south of the jet stream. then return north as the next disturbance in the flow approaches.
Yesterday, the temperature hit 92 at Newark, New Jersey, and 90 in Boston. The following map shows a northerly flow affecting the Northeast today, and so it will be noticeably cooler and less humid.
This map shows lightning strokes from 8 a.m. ET yesterday through 7:54 a.m. ET today. There was quite a bit of it in Utah, Colorado, New Mexico and Arizona. For the whole map, 156,172 lightning strokes were recorded.
Looking at the west-to-east upper air flow over New England well ahead of the storm, it seems like the hurricane should stay out at sea, However, as we look through the series of maps, we see the upper-air flow congealing into a strong eastern trough that helped the storm to come right up the coast instead of heading out to sea.
On this satellite picture, we can see the basically dry weather in the Eastern states. The cold front that will ease the midweek heat in the Northeast is shown by the band of thunderstorms in the Midwest. The thunderstorms may weaken and become more scattered as the front comes into the Northeast.
A storm in the tropical Atlantic is being observed for possible strengthening. This map shows the variety of models purporting to show where the center will go. Most solutions suggest it stays well offshore, but you will notice a few outliers suggesting more threat.
