OceanStWx Posted April 3, 2011 Share Posted April 3, 2011 Cumulus off to our west are looking a bit more vertically developed. The cirrus shield to the west is the leading edge of the jet forcing (lift), and you can see on the satellite how the Cu starts to grow more congested as it approaches.

OceanStWx Posted April 3, 2011 Share Posted April 3, 2011 Yup, from nothing to 40 dbz in 1 scan, two counties east of DMX. That 40dBZ is up through 27kft, so it's a legit convective shower. Link to comment Share on other sites More sharing options...
