SPC Feb 28, 2022 1630 UTC Day 1 Convective Outlook

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0947 AM CST Mon Feb 28 2022 Valid 281630Z - 011200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few thunderstorms are expected across parts of northern Florida and southeast Georgia today. ...Synopsis... Thunderstorm potential today will largely be limited for most of the country amid modest height rises across the western/central CONUS and persistent surface high pressure from the southern Plains into the Northeast. Although somewhat poor mid/upper-level lapse rates were sampled across northeast FL in 12Z soundings, thermal profiles should improve through the day as a weak upper-level wave approaches the region and cools temperatures aloft. Shallow convection is already noted across northern FL this morning, and this activity should gradually deepen through the day as profiles become more supportive of deeper convection. Isolated thunderstorms across northern FL should increase in coverage along the FL/GA coast late this afternoon before moving offshore tonight. ..Thompson/Moore.. 02/28/2022 Read more CHECK UPDATE ZOOM GRAPHIC
