More October Snow and Hurricane Sandy

On October 13th, freeze warnings (light blue) were in effect across most of the northeast, and there was a frost advisory (blue) for Washington DC:

The low temperature that morning at Dulles Airport was 30.

On the night of October 24 (Wednesday), this storm began producing significant snowfall in Nebraska:

Up to 4" fell near North Platte and Broken Bow, and CoCoRaHS observers reported 6" in the panhandle near Sidney. Another system put down more snow last night across Wyoming and Colorado, with 8" being reported by a CoCoRaHS observer 17 miles northwest of Cheyenne. Snow is being reported currently in Garden City, KS.

Hurricane Sandy is currently moving northward through the Bahamas toward waters 1-2 degrees C above normal:

Buoy 41001 is 150 nautical miles east of Cape Hatteras and near the center of the forecast track, and is reporting a water temperature of 79.2 F. Sandy is forecast to continue moving to the north until Sunday or Monday (the 28th or 29th) when a perfectly timed shortwave trough digging into the Mid Atlantic will turn it to the northwest or even west and into the East Coast. Landfall appears most likely to be at Delmarva or New Jersey. Because of the strong westerly component to the track, areas to the north of landfall will have an unusually high impact from wind and storm surge.
