My guess is is keeps chugging until it gets closer to the upper low and is captured and starts becoming vertical, that's when it is likely to slow and almost stall before lifting back out but that's just a guess.

Thanks, Wes. Your "guesses" generally pan out pretty well.

Also, if it's not too dumb a question, can you (or anyone) explain "baroclinic intesification?" I've read that as Sandy goes extra-tropical, that's the deepening that we should expect to see.

I think that has contributed to Sandy's strengthening some already. IN this case approaching trough had a really nice double jet streak structure to enhance upper level divergece along the frontal boundary that was approaching from the west. The trough would have probably formed a noreaster without Candy. Whenever you have strong upper level divergence you are removing mass (air) from the top of the column which helps lower pressure. Negative tilting troughs like this one generally have stronger upper level divergence than other troughs. as tropical system gets closer to the through it increases the temperature gradient along the front and baroclinic zone which strengthens any lifting along it. Add lots of moisture and then you get that latent heating to add fuel to the system. That's a real simplistic answer. Others who have been to school more recently can probably do a better job explaining it.

Agree 100%. This changes very little outside of the very near term IMO. This sucker likely still has a reserved parking space around the Mason Dixon.

Best post I've read all day.. thanks!

New LWX snow map

I'm going to say we see some flakes around here in most of northern virginia tomorrow morning. I will bump this early tomorrow.

The surface temps tommorow morning are forecast to be in the upper 30 so it better be preipitation pretty hard. Light precipitation and temps that warm usually don't work.
