Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0357 AM CDT Fri Jun 23 2017 Valid 261200Z - 011200Z ...DISCUSSION...

While a few afternoon storms are possible across the central and southern High Plains, the overall threat appears minimal due to weak shear. On D5/Tue, the upper trough will lift east, with a brief period of shortwave ridging before a low-amplitude wave emerges into the northern High Plains. Moisture will be in the process of returning north, and, midlevel flow looks to be marginal, but perhaps minimally supportive of a feread more »
