LAPS has finally caught up a bit.\u00a0 Seems to be struggling a little with the line of storms crossing the IA\/NE border.\u00a0 Here’s LAPS forecast 1930Z column max reflectivity<\/p>\n

Here’s DMX-88D from 19:30.\u00a0 Notice model underestimation of developing line.<\/p>\n

Jump ahead to 2030Z.\u00a0 LAPS had that initial cell move no the NE and dissipate completely, then rapid redevelopment of convection between 20:15 and 20:30Z near the IA\/NE border again.<\/p>\n

\"laps2rawing\"<\/a><\/p>\n

That initial line of convection never quit, though…and by 20:27Z a much stouter line of convection was continuing and farther east than what LAPS has indicated.\"rad2Drawing\"<\/a><\/p>\n

What remains to be seen…here’s the LAPS forecast valid 2200Z.\u00a0 Line of convection continues…what seems odd is the east\/west line of something that develops near the IA\/MO border and is moving northeast. Also of note…an east\/west, wave-like formation in the CAPE forecast that drifts in from the south.\u00a0 Anomalous CAPE ridges spurring on a convective response in the model?\u00a0 Is this a model issue near the domain edge or is there a process that the model is trying to pick up on?\u00a0 someone remind me to check at 22Z!\u00a0 db<\/p>\n

Update: it’s a boundary condition issue.<\/p>\n
