Just in case you missed it... I updated the thread but more importantly... An unprecidented event is taking place where NWS offices in THE ENTIRE COUNTRY are asked to send weather balloons up every 6 hours.
Remember my posts on how cold it was going to get in the East? Well someone is going to ruin that for the NorthEast but take a look at where the cold goes because of it.
Given that ocean temperatures along the Northeast U.S. coast are about 5°F above average, there will be an unusually large amount of water vapor available to make heavy rain. If the trough of low pressure approaching the East Coast taps into the large reservoir of cold air over Canada and pulls down a significant amount of Arctic air, as predicted, the potential exists for the unusually moist air from Sandy to collide with this cold air from Canada and unleash the heaviest October rains ever recorded in the Northeast U.S. Another huge concern is storm surge flooding. Sandy is expected to have tropical storm-force winds that extend out more than 300 miles from the center, which will drive a much larger storm surge than its winds would ordinarily suggest.

This could be a historic cyclone in the Atlantic states…or it could just turn out to sea – lol.
It’s driving me nuts – lol. 960 Mb (28.35 in) is a severe system – Hurricane Donna (1960) was the last time a hurricane had a pressure that low…and made landfall between VA Beach and Cape Cod. So it would be a rare event. If it makes landfall above DE but south of Long island and hooks NW (meaning the eastern side of the cyclone passes over NJ/CT/MA/RI) it could be really bad. You know that tides are astronomically high on Mon/Tue....this would only add to the storm surge.
Hopefully this won’t happen; I’m still cleaning up tree damage and roofing issues from Irene last year.
Things happen in a hurry at 40.1 N. Latitude and 5,000 ft.
It was 80° yesterday afternoon, but tonight the lawns and roof tops are white with snow. We have a brisk NE. wind and the air is swarming with a hoary blinding snow. The streets are just wet, but if this keeps up we could have significant accumulation.
Temp. is 32° F. and the wind is NE at 21, gusting to 32 mph. One essential ingredient to a snow STORM is wind. It can certainly snow without wind, but if you don't have those gusty winds, you will not have a big storm. The winds picked up big time this afternoon as the moist air hit the mountains. Snow was inevitable.
Snow lovers, eat your heart out. It is happening here.
Met office predicting 5c and sunshine for tomorrow. Pretty amazing for October that the temp will rise so little.
I see it's snowing in Shetlands.
I still have temperatures forecast of 10C tomorrow, but yes that's a few degrees below average...
The October average high in Lerwick is just 10.2C/50.4F & was shocked to see that their record high is just 23.4C/74.1F!
