This is a video made late this afternoon showing where Sandy should go and what impacts to expect. The storm is still well out at sea, but it was supposed to be there according to previous forecasts. However, the various computer models have insisted the storm is about to hook to the left and head straight for the coast. The video shows where the storm should be at various times during the next couple of days. Keep in mind that dangerous wind and rain conditions will arrive long before the center reaches or passes you. In fact, the weather will slowly improve right after the center passes, but the damage will have been done. I'll write to you again tomorrow morning.
Tropical Storm Erika could eventually affect Florida and other sections of the Gulf Coast or Southeast, but for now it poses no threat for the Northeast. This map shows the storm as of early this morning.
The second concern is Erika. The map below shows what many different models area saying. While there is a good agreement in the short range, the longer-range spread is quite larger, with tracks ...
This picture shows where Erika is. The various models show a track toward Florida with a lot of uncertainty after that. If it does make it to land, then moves slowly (steering forces look weak), it could be a major rain producer.
It is way too early to be definitive about these storms, but the many models being used in predicting the track have closer agreement than many storms have at this point.
On this satellite picture, you can see a cold front approaching the Appalachians. That front helped produce thunderstorms in the Midwest yesterday, but that activity died out overnight. It is likely to reactivate today, with...
...shows a north-south trough line over New England. Moist air will approach this line from the southeast while northerly breezes bring in dry weather west of the line. As the front stalls then slowly backs up, some moisture can spread westward later in the weekend.
