SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1241 AM CDT Tue Sep 29 2020 Valid 301200Z - 011200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected Wednesday. ...Synopsis... Model guidance has trended away from the development of a mature upper low over the Southeast early Wednesday in favor of a less amplified, more progressive embedded shortwave trough. Consequently, the front is now expected to be well off the East Coast, with any moist and unstable conditions confined to central/southern FL. Upper troughing is still expected to persist across the majority of the central and eastern CONUS, with moderate to strong flow aloft arcing cyclonically from Alberta through the northern Plains, mid MS and OH Valleys, and Northeast. Forcing for ascent and cold temperatures aloft attendant to a shortwave trough moving within this upper trough may contribute to a few storms deep enough to produce lightning across the Upper Great Lakes region. Expansive upper ridging will remain in place across the western CONUS. Stable conditions beneath this ridging will preclude thunderstorm development. ..Mosier.. 09/29/2020
