SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1127 PM CST Mon Feb 24 2025 Valid 251200Z - 261200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm probabilities are less than 10 percent across the lower 48 States today. ...Discussion... Strong upper trough is moving onshore along the Pacific Northwest Coast early this morning. This feature will deamplify a bit as it digs southeast across the northern Rockies into the central Plains/upper MS Valley region by the end of the period. As this short wave shifts inland, surface pressures will build over the northern Rockies/Great Basin forcing a cold front into the eastern Dakotas-central NE-central CO by 26/00z. Large-scale forcing ahead of this feature will contribute to mid-level moistening within a steep lapse rate environment. Forecast soundings along/near the frontal zone suggest weak mid-level buoyancy, likely sufficient for at least shallow elevated convection. While a few of the strongest updrafts may penetrate levels necessary for lightning discharge, current thinking is the probability for thunderstorms is too low to warrant a risk this period. ..Darrow/Thornton.. 02/25/2025 Read more
