SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0646 AM CST Mon Feb 01 2021 Valid 011300Z - 021200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across south Florida this morning, but severe storms are not expected. ...Synopsis... In the wake of a deepening cyclone just off the Mid-Atlantic coast, a surface cold front will move across south FL and offshore by late morning. In the interim, a low-level air mass with dewpoints in the low 60s and weak buoyancy will support a continue threat for isolated thunderstorms prior to frontal passage. Otherwise, a lead shortwave trough will approach the northwest CA and OR coasts late this afternoon, though the larger-scale trough will remain offshore. Very weak buoyancy will approach the immediate coastal areas, but any marginal thunderstorm threat is expected to remain too low for an outlook area. ..Thompson.. 02/01/2021
