1. In my opinion sandy will stay as a warm core system up until landfall but a dryslot may develop in the SE quadrant of the storm as the cold core trough goes negatively titled.
2. After landfall sandy will merge with a giant cold core trough over the south east.
3.The phasing of the polar jet stream will cause historic pressure falls and what i think could be a sub 940mb storm at landfall as it continues to strengthen over the gulf steam water. It will get stronger then it was last night between saturday and monday in my opinion as it moves north with a landfall off of coastal NJ or MD.
4. Historic flooding and power outages may occur and a potential disaster scenerio for philadelphia as water piles up in the delaware bay with a SE wind which would flood the delaware river contributing to major flooding across the area. The wave watch model illustrates this point well and locations all along the eastern seaboard should take safety measures.
5. Major flooding and wind damage will take place from this system both along the coast and inland. Here in ontario heavy rain, wind and possibly some snow may occur depending on how much cold air gets pulled in on the back side of the trough. The track of the storm will also matter with a solution north landfalling in NJ or a solution similar to the 18z GFS may mean more cold air on the back side and less warmth being pulled northwards in front of sandy. Also if the storm does not move inland too far then more cold air could move in. Nonetheless people in southern ontario and quebec should be keeping an eye on the evolution of this storm. Current model runs are showing significant wind and rain for southern ontario. Are these amounts overdone? Unknown at the moment but if these conditions do develop and the models stay consistent with what they are depicting then a Hazel like scenerio may be setting up for inland areas with extensive damage possible. This is a possible scenerio but should not be overlooked and it should be understood that we do not have a good grasp yet on the exact impacts of this system. I still think that a high impact storm is coming for inland areas but we will have to see to what extend these occur. Is this just a minimal TS for canada or something that can really make an impact and be remembered for a long time and truly feeling historic?
European has 932 off the NC coast weakening and becoming cold core inland but retains strength and high winds are being felt on the back side.
GFDL sub 930 with devastating scenerio for NYC:
18z GFS has 930 MB storm and as it moves into NJ has 70+ kts 900mb winds across southern ontario. thats very impressive!
