SPC May 17, 2023 Day 4-8 Severe Weather Outlook

LIVE MAP (ABOVE) ... Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0441 AM CDT Wed May 17 2023 Valid 201200Z - 251200Z ...DISCUSSION... Medium-range models appear to be in reasonably good large-scale agreement on the general upper flow pattern over the U.S. through Day 6. Beyond this time, though model differences increase, it nonetheless appears that large-scale/organized severe weather potential will be low through the end of the period. In the shorter term, limited severe risk will likely exist from portions of Texas eastward across the Gulf Coast states and Georgia day 4 (Saturday), as a cold front continues to sag southward toward the Gulf of Mexico. At this time however, both instability and shear appear likely to remain somewhat limited, which suggests that stronger storms should remain isolated. Once this front reaches the northern Gulf Day 5, surface high pressure is forecast to expand southeastward across the central and eastern U.S., and likely remain there through the end of the period. As such, overall severe risk should remain limited through the period. Read more CHECK UPDATE ZOOM GRAPHIC
