SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1230 AM CDT Fri Mar 30 2018 Valid 301200Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible from the eastern Carolinas south into northern/central Florida today. Severe thunderstorms are not expected. ...Discussion... Broad cyclonic flow aloft is forecast to prevail across the U.S. today, though overall deamplification of the flow field is expected as embedded short-wave troughing traverses the Ohio Valley through the day, and then the Northeast/New England overnight. At the surface, a cold front is forecast to cross the Atlantic Coast states through the day, clearing all but Florida by evening. Ahead of this front, weak instability will prevail -- insufficient to support vigorous convection. Showers -- with occasional lightning locally -- will affect the eastern Carolinas and southeast Georgia, and into northern and central Florida during the day, moving offshore as the front advances. While the deep-layer wind field will remain strong enough to otherwise support organized updrafts, the anticipated lack of warm-sector CAPE suggests minimal severe risk -- insufficient for inclusion of any risk areas. ..Goss/Leitman.. 03/30/2018 Read more
