SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1127 AM CST Wed Nov 05 2025 Valid 061200Z - 071200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Thursday or Thursday night. ...Discussion... A progressive pattern with multiple embedded shortwave troughs will be present across the Northwest to North-Central States on Thursday. A pocket of cooler mid-level temperatures associated with one trough may aid in very isolated thunderstorms across parts of the northern Rockies. Farther west, a strong mid-level jet and associated shortwave trough should reach the Washington coast by late afternoon. Cooling temperatures aloft and some increasing moisture amid onshore flow may result in a few low-topped thunderstorms. Strong shear and strong flow below 1km would support an isolated damaging wind threat, but instability appears too limited at this time. In addition, some isolated storms may also persist inland across northern Washington and perhaps into northern Idaho and far northwest Montana on late Thursday night as the trough moves inland. As a mid-level trough amplifies across the Plains on Thursday afternoon/evening, a surface low will slowly deepen as it moves from the Upper Midwest to the northern Great Lakes. A strengthening low-level jet ahead of the associated cold front will transport some moisture northward across the Ozarks. As this moisture advects northward, a few general storms may develop amid weak elevated instability and isentropic ascent across parts of the Midwest. ..Bentley.. 11/05/2025
