However, the overall severe threat should remain isolated. DISCUSSION...Scattered strong thunderstorms have been increasing over the last couple of hours, particularly over southern MT. Across the northern High Plains, strong surface heating has supported upper 80s to 90 F surface temperatures, and with 9 C/km low and mid-level lapse rates in place, over 1000 J/kg MLCAPE has become commonplace. Nonetheless, deep-layer flow and subsequent shear remains modest, especially where richer low-level moisture and resultant instability are in place. Therefore, multicells and transient supercells will continue to percolate in intensity over the next few hours. Severe wind and hail are possible, but should occur on a more intermittent and isolated basis. ...Squitieri/Guyer.. 06/26/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!9HtVXromFouK7c6h23NNKg65oF4MbkUrR_ArEj1_6NwbZVaWVSiycDlaMWeI_Tq3GdcTmlIUK= _gCPlE3F8VRogET4uU$ for graphic product...
