SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1026 AM CST Sun Nov 08 2020 Valid 081630Z - 091200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTH FLORIDA... ...SUMMARY... A tornado threat may develop from late this afternoon through tonight across south Florida and the Keys, as Tropical Storm Eta approaches. ...South FL... TS Eta is moving slowly northwestward toward the FL Straits. Radar/satellite imagery show an area of heavier precipitation on the north side of the center. This area is forecast by most CAM solutions to approach the coast of southeast FL and the upper Keys after dark. Current observations and forecast solutions suggest that this activity will not be particularly organized, with relatively weak UH tracks/convective elements noted. Nevertheless, low-level shear will maximize during this period, which appears to be of greatest concern for a tornado or two this forecast period. The main time of concern will be roughly from 00-06z. Based on current guidance, will maintain MRGL risk, but will continue to monitor observational/model trends. ..Hart/Mosier.. 11/08/2020
