Sunday 5 PM
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.
The wind will not roar like a lion in the Northeast on Sunday March 1. It certainly won't be lamblike. However, with more cold and snow in the forecast, it might be suitable for this group:
The surface analysis shows to low pressure area off the North Carolina coast, a large cold high pressure area in the northwest corner of the map, and a broad northeasterly flow of cold air between pressure centers. Cold will continue in this whole area through Saturday.
In reaction to this, the flow aloft may become more southwesterly over the Eastern states. This would promote less chill in the Northeast but cause more storminess. The following maps are U.S. model predictions of total snowfall and precipitation from now through next Wednesday.
Is there any warmth in future? The following two maps suggest the answer is yes, but it is only temporary. This map shows projected flow aloft for next Tuesday. If you trace the origin of the air, you see a southwesterly flow of air next Monday (March 2).
New York City often has its coldest days when the air comes straight south through the Hudson Valley... rather than from the Great Lakes. This map shows how today's wind flow matches the profile for extreme cold.
There will be a non-uniform snow accumulation pattern because the precipitation will be organized in bands and blobs around which precipitation rates vary quite a bit. This map is designed to give a quick overview about expected snow accumulations:
