I'm still trying to wrap my brain around the idea of sustained 60 mph winds over Lake Erie. IIRC the flow would not have been over the lake for the blizzard of 78 and likewise for hurricane Ike remnants. I have no idea if there are storm surge models for Lake Erie, but you've got to wonder if that will be an issue. I can't think of any other events that would have produced 60 mph winds out of the NE for coastal Ohio.

A storm surge is definitely possible for Lake Erie or any Great Lake. Happens on the southern end of Lake Michigan once every year or every other year - usually in the winter.

Newest NHC forecast map cone. Looks like they are siding with the EURO.

There will be damage here along the coastline. The shore to west of Cleveland is the most densely populated place between Chicago and the East Coast. You have a lot of buildings and a ton of huge oak trees with intact leaves, combine that with wet soils from a very wet fall and strong winds coming directly from the lake and there will be fallen trees everywhere, and when they fall they go through rooftops. As exciting as this may be, I know it spells damage here.

That's probably being conservative at this point.

ATTENTION FOR THE SHORT TERM PERIOD WILL FOCUS ON THE MOVEMENT OF

THE REMNANTS OF HURRICANE SANDY. CURRENT THINKING IS THAT THE

CENTER OF THE LOW WILL STRUGGLE TO GET WEST OF CENTRAL PA BEFORE

DRIFTING INTO EASTERN NY ON WEDNESDAY. THE REGION SHOULD SEE AN

EXTENDED PERIOD OF WRAP AROUND MOISTURE. THE MAIN STORY FOR

NORTHERN OHIO INTO NW PA APPEARS TO BE THE WIND. ADVISORY LEVEL

WINDS ARE A GOOD BET WITH GUSTS OF 45 TO 50 MPH POSSIBLE BY

MONDAY THROUGH AT LEAST TUESDAY NIGHT. THIS PROLONGED BATTERING

FROM A NORTHERLY DIRECTION COULD TOPPLE MORE TREES THAN USUAL.

SOMETHING TO MONITOR CLOSELY FOR THE BEGINNING OF NEXT WEEK.

Areas near the lake at least should be able to gust higher. There are really strong winds just off the deck at CLE (18z GFS has 900 mb winds of 65 kt at 96 hours). Precip is a double edge sword...on the one hand it could cause enough low level stability to keep gusts a bit in check but on the other hand the high winds may be able to mix down in heavier bursts.

How is this looking for the Toronto and southern Ontario region? The 18z GFS scenario would seem to have Sandy hitting us with high winds, possibly close to tropical storm force.

I was wondering the same thing. I don't think many people in Toronto have a clue about this storm. It's expected to rain a lot this weekend with the passage of a slow-moving cold front. The addition of even more rain this weekend could really be a problem with the ground already being so saturated.
