AgeeWx Posted April 30, 2012 Share Posted April 30, 2012 There's really solid rotation... and of course as soon as I say that the next scans prove me wrong. looks like I wasn't the only one not putting much stock in DDC today. Link to comment Share on other sites More sharing options...

knitwx Posted April 30, 2012 Share Posted April 30, 2012 Today is looking good off the Caprock. Not much to add to Panhandle magic. Tomorrow, Tuesday, I'd focus on whatever outflow boundary can drop through central Minnesota after morning rain. Northern Iowa may also be in play with backed low level flow. I know that is assuming a lot. My point is just that the OFB intersection with the DL will be better than down the DL in this situation. We're not in Kansas anymore. Farther south into Nebraska veering and/or capping could be an issue. Could. It may still go. On the other side, believe northern Minnesota stays stable in stratoform rain. Farther northwest, southern Manitoba might be some low-top sups close to the surface low. That is a separate target area in my mind. My primary would be depart MSP. Unfortunately I'm just a bit out of range for that and air fare is atrocious. My sister and I discussed this. She is setting up near Alber Lea MN Tue. Good Choice? We figured the road choices were many. I hope she won't be too far East. Link to comment Share on other sites More sharing options...

Minnesota Meso Posted April 30, 2012 Share Posted April 30, 2012 For Tomorrow 5/1. It looks like the NAM and the GFS have started to back off on the cape vales in MN according to their 18z runs. (I can't post pics, password protected site), for instance the Nam now shows at 7pm on the 18z run cape values around 1700-2000 for the MSP area as opposed to 2000-2500 on the 12z run. The GFS 18z has moved in the same direction. With the lack of CIN and the cloud cover that both models were showing on the 12z runs, this is not surprising. It looks like they will be going to the ECMWF solution which shows the best cape values just south of MSP for tomorrow night. But that is not a bad thing for severe convection for MSP, often times the biggest storms will set up along the northern edge of the greatest CAPE values. For instance this looks somewhat interesting. Link to comment Share on other sites More sharing options...

Given the magnitude of the low level and bulk shear, CAPE like that will be more than sufficient (300-500 J/kg probably isn't going make a whole lot of difference), any breaks in the clouds will obviously exacerbate the situation.
