2015-06-02 EVENT: ND,SD,NE

[Mike Marz]

Tuesday has been looking somewhat intersting for almost a week now. Both the NAM and the GFS are forecasting a good to great amount of CAPE building up tomorrow across portions of ND, SD, and NE. Mid and upper level winds are not forecast to be great, but they could be good enough to get the job done. If I pull the trigger on this setup, I am hoping to get storms developing somewhere in western/southwestern SD and hope one of them becomes dominant and stays discrete. The 850s are forecast to strengthen during the evening hours, and this will really boost the low level shear for any discrete storms roaming around out there. I am intersted to hear what other people think tomorrow could produce.

Looks good in the eastern Dakotas. Stay east of the surface low. Western Nebraska may have sups but not enough low level shear south of sfc low.

Dakotas have better speed shear and low level turning especially along boundaries. Appears WF will sit over ND. Nebraska OFB may lift over SD. Both intersections with DL/CF look good. While OFB may have a little more CAPE the WF will have more low level turning today. If CAPE is not too much lower WF I favor WF today. Normally I favor OFB but upper speed shear is notably better WF today.
