Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0317 AM CDT Sat Aug 09 2025 Valid 121200Z - 171200Z ...DISCUSSION... A shortwave trough will move from the northern Plains into the Northeast during the Tuesday/D4 to Wednesday/D5 time frame, with an initial push of drier air southward across the Midwest/Great Lakes. Stronger instability is forecast to redevelop by Thursday/D6 and beyond as a low-amplitude upper trough moves across the northern Rockies and Plains and increasing southerly low-level winds bring dewpoints into the mid 70s F northward across the Mid MO/Upper MS Valleys. This may yield one or more severe events across parts of the northern Plains to upper MS Valley, but confidence is low. Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0232 AM CDT Sat Aug 09 2025 Valid 111200Z - 121200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not forecast for Monday. ...Synopsis... On Monday, a weak upper trough will remain over the central US, but winds aloft are forecast to dwindle as a primary midlevel wave sweeps across the northern Plains to upper Great Lakes. A weak surface trough may remain from the southern Plains into the lower MO Valley, but lift here will remain subtle. Overall, a moist and unstable air mass will still exist, but the lack of large-scale ascent and weakening lapse rates aloft is expected to mitigate severe storm potential. That said, a corridor of strong storms is most likely during the afternoon/early evening from parts of West TX across OK, eastern KS, MO and IL, with areas of gusty winds. ..Jewell.. 08/09/2025 Read more
