A few storms may produce hail on Thursday from far northeast Kansas and southeast Nebraska across northern Missouri and into much of Iowa. ...Synopsis... On Thursday, a progressive upper trough will move from the central and northern Rockies into the Plains, as upper ridging develops from the OH Valley into the Northeast. Surface high pressure will be in place over much of the East in the wake of the previous days cold front, providing generally stable conditions. Lee troughing and an associated cold front associated with the mid-level trough will traverse the central Plains Thursday afternoon and move into portions of the Midwest by the evening. Some low-level moisture will advect northward ahead of the cold front, but will mix out as it does with only minimal surface-based instability expected. A few storms may develop during the afternoon along this front, but will likely struggle to be severe due to the limited instability. Once the 1 to 2 km layer starts to moisten after 00Z in response to a strengthening low-level jet and mid-level temperatures start to cool, more substantial elevated instability is expected. Sufficient forcing due to isentropic ascent and dCVA will support some elevated convection during the evening and into the early overnight hours. Moderate instability and 30 to 35 knots of effective shear may support a few supercells capable of large hail. ..Bentley.. 10/23/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
