Pretty Epic band of Lake Effect rain going on right now just north of Buffalo. Should be drifting south through the area tonight.

Yea as that surface shortwave passes to the east, winds will become more southwesterly to west-southwesterly. There also looks like there was some lightning detected over the center of Lake Erie.

142 feet higher then the Buffalo airport is negligible at best. That difference does not cause up-slope btw. :facepalm:

i was talking about downtown BUF near the lake which is at or below 600 feet. Definitly had that upslope look to it as precip was happening right where the elevation increases are. The heaviest rain was to my S and E where the elevation is higher than it is here.

Quite enjoyable reading the New England forum about this. Eh, it's too far out for now.

Yeah there is a ton of uncertainty in this situation. In order for Sandy to become an intense extratropical low and track near the east coast, it has to phase with a trough forecast to move into the Ohio Valley and southeast. Considering the average NHC track error is about 250 miles at 5 days out, a forecast 7 days out is probably going to have an even greater error meaning that a phase is more uncertain. A weak ridge forecast to be northeast of Sandy may guide the system towards to the coast, depending on its strength. There is also uncertainty in the amplitude and speed of the trough which could depend on how much a frontal wave deepens ahead of the trough.

if this were to happen Wed have to call it the perfect storm part duex.

The 00z Euro has Sandy phasing with the trough over the midwest and making landfall in Central NJ. It gives most of WNY from west of ROC down through the shore of Lake Erie and into BGM over 1 inch of liquid equivalent frozen precip. The higher terrain of the Chautauqua ridge gets over 3 inches of frozen precip.

The 06z GFS does not phase Sandy with the trough, however it still produces an interesting scenario. An inverted surface trough is forecast by the model to develop as the upper level trough becomes more amplified and negatively tilted. This leads to rising motion along the front associated with the upper level trough, with plenty of moisture being tapped from Sandy. The inverted surface trough then deepens some to form a surface low which retrogrades into Northern NY. This scenario also produces frozen precip with the BUFKIT profile for Jamestown showing 1 inch of liquid equivalent snowfall.

The GFS seems like more of a lake enhancement situation with some dynamic cooling enhanced by the right entrance region of a south-north oriented 250 mb jet. The Euro shows more of a synoptic event, with maybe some lake enhancement at the end.

The GGEM has a similar solution to the GFS, with Sandy tracking out to sea and a secondary low developing off the coast of New England. Right now, it seems like the Euro has more support from the ensembles and has been fairly consistent in phasing the storm. However, the GFS scenario or something in between such as a later phase than the Euro could also occur.

Well, IMO, it's ALMOST game on for the W. Southern Tier and Northern PA hills.....snow from a former hurricane!!!!....only from the dreams of a child!!!

im hoping for a slight track east. But even if it didnt move east I think the dynamic cooling of the column may give me some snow here at 880 ft. Obviously not all snow but prob the first real flakes and maybe accumulation if the year.

I'm just going to assume we are all speechless.

lol

Euro and GFS are pretty big on wind in western and CNY...could be really good, even all the way over here.

That 850 jet cranks overhead as the low retrogrades. Storm force winds and hurricane force gusts per the gfs on Lake Ontario. Euro also has 45-50 kt sustained on the lakes on the wunderground graphics.
