CoastalWx Posted February 1, 2013 Share Posted February 1, 2013 What does csi and mpv stand for? Conditional symmetric instability and moist potential vorticity. If you reeeaaallly want, you can dive into those topics and have your head explode. LOL. CSI is what can cause narrow, but heavy bands of snow and rain actually. It is an instability that is released when the criteria is met and a parcel is allowed to rise in a slant wise direction. MPV reduction is a key ingredient to help with CSI. It reduces the instability in a layer (but not pure upright convection) such that the slantwise moving parcel has a good push to move vertically. If you want, I suggest anything related to James Moore who has modules and PPTs out on this topic. This guy was amazing. RIP though. Link to comment Share on other sites More sharing options...

CoastalWx Posted February 1, 2013 Share Posted February 1, 2013 Could have been some CSI, but to me...it didn't have that look when I caught the radar images earlier. I'm sure it was possible with pretty strong moisture and temp gradients. Nice MPV reduction can just enhance the vertical component of the circulation. The 12z GFS sounding had a conditionally unstable look at the top of the saturated layer which isn't surprising. That can lead to more convective type stuff. Just a guess anyways, I don't have AWIPS EPV type tools at my disposal either. Link to comment Share on other sites More sharing options...

Bliz299 Posted February 1, 2013 Share Posted February 1, 2013 As of noon 4.1", peak gust 42mph@10:50am. At 12:30pm 28°, intermittant light snow, Driving through North Cape May at 10am near whiteout conditions. Loved it! Hope the next two do as well.

A whole bag of 'em! I fully expect it to either a) crap out as we get closer or trend too far south to affect me...Its been primarily option a so far this cold snap, but i actually like option b for the 2/5-6 clipper..seems to have the more potential as many have noted, but it will probably miss me (Keep in mind I'm up in stamford, CT so option b doesnt necessarily apply to this forum) Link to comment Share on other sites More sharing options...

That band ment business man, I was at work in Ardmore didn't even know those 2 bands even fired up until a coworker said its really snowing outside, loaded radar scope and whoa, then once done I measured at work had a half inch of surprise snow.

_AR_ Posted February 1, 2013 Share Posted February 1, 2013 Currently HEAVY snow right now with this squall. Near zero visibility. Intense! Roads are very bad in spots. Link to comment Share on other sites More sharing options...
SP Posted February 1, 2013 Share Posted February 1, 2013 Made it into Poconos. White out squalls. Accidents and closed roads everywhere Around 209. 115. 940 and 80. 3-4 inches and vis down to a few hundred feet. Be careful. It was amazing but dangerous as heck going through effort.
