A watch is possible should convective trends warrant. DISCUSSION...Thunderstorms have initiated near a stationary boundary in southern Minnesota. This activity is tied to an upstream shortwave trough in western Minnesota per water vapor imagery. Filtered heating through cirrus clouds has allowed temperatures to rise into the low/mid 80s F. The very moist air will support around 1500 J/kg MLCAPE. Continued heating and increasing mid-level ascent will eventually lead to widely scattered to scattered storms. Isolated damaging winds and hail may occur with the strongest storms, though low/mid-level lapse rates are not overly steep. The surface reflection of the shortwave trough is also rather nebulous. Even so, low-level shear is sufficient for weakly rotating storms conditionally capable of a brief tornado. A watch may be needed this afternoon. ..Wendt/Hart.. 07/08/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...GRB...MKX...ARX...MPX...DMX...
