SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook CORR 1 NWS Storm Prediction Center Norman OK 0107 AM CST Sat Nov 07 2020 Valid 081200Z - 091200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF SOUTH FLORIDA... CORRECTED TO ADD SOUTH FLORIDA INTO THE THIRD TO LAST SENTENCE ...SUMMARY... A marginal tornado threat is expected to develop Sunday night across south Florida as Tropical Storm Eta approaches. ...South Florida... The National Hurricane Center is forecasting Tropical Depression Eta to become a tropical storm and move northward across Cuba on Sunday. The outer rainbands of Eta are forecast to move northward into southern Florida near Miami by Sunday evening. As the center of Eta approaches south Florida Sunday night, low-level winds will steadily increase. NAM forecast soundings from 06Z to 12Z on Monday for Miami show winds near 50 kt at 1000 feet above ground level. As a result, 0-1 km shear is forecast to increase to near 40 kt late Sunday night which should support a marginal tornado risk. Cells that remain semi-discrete moving inland into the Florida Keys and south Florida will have potential to rotate. These storms could be associated with an isolated tornado threat. For these reasons, a marginal risk area has been added in parts of south Florida for this outlook. ..Broyles.. 11/07/2020
