MN/WI A fast moving shortwave trough over ND will track southeastward into the upper Midwest today. 12z model guidance is in general agreement that a pocket of modest CAPE will develop this afternoon over central MN in a region of broken clouds and rapidly cooling mid-level temperatures. This will likely lead to scattered thunderstorm development, with storms tracking into western WI before weakening this evening. Forecast soundings show steep mid-level lapse rates and strong westerly flow aloft. Given the strong large scale ascent, a few relatively low-topped supercells are possible with large hail being the main risk. A small SLGT risk has been added for this scenario. East TX into the Southeast A very moist and moderately unstable air mass is present today across much of east TX and LA into southern MS/AL/GA and north FL. Dewpoints in the mid-upper 70s and strong heating will lead to MLCAPE values of over 3000 J/kg across much of this broad area. This will lead to diurnally driven thunderstorms later today into this evening. Steering flow and vertical shear are weak across the region, suggesting slow-moving and rather disorganized convection. Nevertheless, the strongest cells will pose a risk of water-loaded downdrafts and occasionally gusty/damaging winds. Eastern NC A remnant tropical circulation is moving across NC and will be offshore by mid-afternoon. Until then, an isolated tornado cannot be ruled out in the stronger-sheared environment across the Outer Banks region. Refer to MD #1197 for further details. KS/NE/CO/NM Scattered thunderstorms may develop this afternoon in a zone of low-level warm advection over southwest NE and track into northern KS. Steep lapse rates and sufficient shear for rotating storms could pose a risk of large hail in the strongest cores. Other more widely scattered convection will develop southward into eastern CO/western KS/northeast NM, where gusty/damaging wind gusts are possible. NV A very deeply-mixed boundary layer will develop this afternoon over much of northern NV/northeast CA, along with enough CAPE for high-based thunderstorms. Strong mid/high-level winds and favorable thermodynamic profiles could result in a few storms capable of damaging wind gusts.
