SPC Mar 19, 2023 0600 UTC Day 1 Convective Outlook

LIVE MAP (ABOVE) ... SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1153 PM CDT Sat Mar 18 2023 Valid 191200Z - 201200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on today. ...Discussion... As an upper low crosses Quebec and shifts into the Canadian Maritimes today, remnant troughing extending southwestward across the eastern U.S. will weaken/advance slowly through the period. Upstream, ridging will generally prevail over the West, though short-wave troughing over the West Coast states early will be replaced by a stronger short-wave trough that should approach/reach the Pacific Northwest Coast overnight. At the surface, a cold front is forecast to continue moving southward across Florida early in the period, clearing the southern coast/Keys by early afternoon. Meanwhile, in the wake of the front, high pressure will shift eastward across the south-central and into the southeastern U.S. through the period. Little lightning potential is evident onshore through Monday morning. A few flashes may occur across southern Florida or the Keys early, as the front progresses southward. A couple of flashes will also be possible over portions of the Sierra of central/northern California. No severe weather is expected. ..Goss/Lyons.. 03/19/2023 Read more CHECK UPDATE ZOOM GRAPHIC
